Problems with the engine on the Kia Sportage 3. Kia Sportage (2013)

Kia Sportage 3. Losses engine oil

Cause of malfunction	Remedy

Oil leaks from the nodes of the lubrication system (the nodes themselves or neighboring areas are covered with oil)	Check for signs of oil leakage at the nodes. If oil leakage is not obvious, use an ultraviolet leak detector. Install new gaskets or assemblies as needed
Leakage through glands crankshaft	Replace crankshaft seals
Leaks from engine oil channels	Use an ultraviolet leak detector to check for cracks in the engine oil passages. If there are cracks, replace the cylinder block

Causes of engine oil loss

Sometimes the cause of the engine oil level dropping too fast can be an oil leak. In this case, the first and necessary action will be to check and replace worn parts responsible for tightness - oil seals, gaskets, etc. It is not always possible to notice a leak during a superficial examination, and the consequences of such a breakdown, even without taking into account additional expenses for engine oil, can be quite serious. Therefore, every driver should immediately contact the station Maintenance in cases where the consumption exceeds the figures stated in the service documentation for the car. Each car requires maintenance, and how efficiently and how long the car will work depends largely on its owner. Correct selection lubricant to the required viscosity grades and performance specifications, monitoring the oil level, as well as its timely replacement and regular inspections, can protect your car from many potential breakdowns

Increased engine oil consumption

Lubricant consumption is influenced by factors such as the condition of the gaps in the cylinder-piston group (over time, natural wear of parts is possible, which leads to an increase in oil consumption), the correct settings and adjustments of the engine, the pressure in the crankcase and leakage at those connection points that have seals or rubber hoses, etc. Do not forget about driving style: the prevailing operating conditions have a significant impact on oil consumption. Of course, important criteria are correct selection engine oil and compliance with the terms of its replacement. Oils that do not meet tolerances are not able to provide effective protection for engine parts, which leads to increased wear and, as a result, engine failure. In addition, if in car engine Unsuitable, contaminated or used oil is used, oil foam may form during the rotation of the shaft, which rises through the ventilation system in the direction of the intake system. This not only leads to excessive consumption of oil, but can also cause the system to fail.

What oil consumption in the engine should be normal

Lubrication consumption is one of the important indicators of the general condition of the engine. From some car owners you can hear that the engine does not take oil, that is, the level remains the same or remains within acceptable limits from replacement to replacement.

Others report increased or high flow oil in the engine, which makes it necessary to add lubricant. We note right away that the ICE manufacturers themselves separately indicate the norms for oil consumption in the engine. This means that the power unit can consume lubricant within certain limits, and such consumption is not a malfunction.
This phenomenon is commonly referred to as oil consumption for waste. However, exceeding the norm for adding oil to the engine may well indicate problems with the internal combustion engine, a mismatch of the lubricant with the tolerances and recommendations of the engine manufacturer, etc.

In this article, we will consider what kind of "oil appetite" of various power units can be considered acceptable, as well as what factors and features affect the consumption of lubricant in the internal combustion engine.

All engines use engine oil to a greater or lesser extent. This happens taking into account the characteristics ICE designs, namely because of the urgent need to lubricate the components and parts of the CPG. In other words, the main loss of lubricant occurs as a result of the need to supply lubricant to the cylinder walls.

This area in the engine is a heat-loaded area. For this reason, partial evaporation and combustion of the lubricant occurs. Also, part of the oil is not removed from the cylinder walls by the piston rings, as a result of which the remaining lubricant burns along with the fuel in the combustion chamber.

As a rule, in modern engines the declared oil consumption is, on average, from 0.1 to 0.3% of the total fuel consumption that was spent to overcome any segment of the journey. It turns out that if the car has traveled 100 km, and the consumption is 10 liters of fuel, then the consumption of an average of 20 grams of oil will also be the norm.
It turns out that the lubricant consumption can be considered acceptable if it does not exceed the mark of about 3 liters. per 10 thousand kilometers traveled. At the same time, it is also important to understand that the consumption rate will greatly depend on the type of engine, the degree of its forcing, etc.

For example, for many atmospheric gasoline ICEs, the norm is about 0.1%. On gasoline turbo engines, the consumption rate is noticeably higher. As for the diesel engine, the declared lubricant consumption will normally be greater than any gasoline counterpart and averages from 0.8 to 3%. The indicated 3% are consumed by forced turbodiesels with two turbines, etc.

You can also separately mention rotary motors, which are particularly prone to lubricating fluid consumption. Such units (taking into account their fully operational condition) consume about 1-1.2 liters of oil per 1000 km. run. For reference, in the manuals for different engines it is indicated that the rate of oil consumption for waste is 1 liter per 3 thousand km traveled, that is, about 3 liters per 10 thousand km.
At the same time, manufacturers also note that the consumption directly depends both on the technical condition of the internal combustion engine and on the characteristics of the operation of a particular vehicle (load on the unit, speed, etc.)

What determines the oil consumption in the engine and how to reduce it

As mentioned above, oil is consumed in any engine, since the oil film on the parts to protect against dry friction burns in the chamber along with the fuel charge. If we add to this the natural wear of the internal combustion engine during operation, then the consumption of lubricant increases further.

However, it becomes quite obvious that 3 liters of oil per 10 thousand km. for a small car with an in-line aspirated engine, it can be considered a large expense, while for a powerful unit with a large displacement, this is a completely acceptable indicator. Practice shows that even if the engine began to “eat” oil above the norm, it is more economically profitable to simply add lubricant than to immediately overhaul the engine only because of increased consumption.
The fact is that at many service stations, masters prefer not to diagnose a separate cause. increased consumption oil, and immediately offer the owner to make a major overhaul. At the same time, it is important to take into account that not always in such expensive repairs there is a need.

First of all, lubricant consumption can be increased due to the fact that oil flows out of the motor. In this case, it is enough to replace the gaskets and seals. As a rule, you need to pay attention to the valve cover gasket, cylinder head gasket, front and rear crankshaft oil seal, camshaft oil seals, valve oil seals, etc.
AT different situations grease can flow on the outer surface (leak out) and also penetrate into other systems. For example, if oil flows between the gearbox and the engine, the crankshaft oil seal is to blame, and a puddle may form under the car.

If the cylinder head gasket turns out to be problematic, there may not be any leaks outside, the engine will be dry. In this case, the lubricant will enter the coolant, the coolant will become cloudy, the oil in the engine will also begin to foam, an emulsion will appear under the oil filler cap and on the dipstick.

If the oil is actively consumed in the engine for waste, from exhaust pipe blue oily smoke will come out. In this case, especially compared to a leak, it is much more difficult to establish the cause without disassembling the engine.
However, even in such a situation, you can try to fight the waste before agreeing to a repair. First of all, the lubricant consumption depends on the mode of operation of the motor. In other words, driving at high speeds leads to an increase in temperature and loads, the oil liquefies, it is worse for rings to be removed from the cylinder walls, it burns out, etc.

It is also important to understand that the lubricant may not be suitable for the engine in certain parameters. This means that you need to know which oil to choose for the engine and what features to consider.
If the motor is worn out, then in parallel it is necessary to take into account the features of the selection of oil for engines with high mileage. In a nutshell, the reduced viscosity material forms a thin film that the oil rings cannot remove from the walls. If the lubricant is thick, then the film is very thick, while the rings cannot remove such a layer in full.
In view of the foregoing, it becomes clear that you need to use the most suitable oil both in terms of tolerances and the high temperature viscosity index. For example, from the list of recommended lubricants in the manual, you need to select a product with a higher viscosity compared to what is currently filled.

You can also switch from synthetics to semi-synthetics, which also in some cases reduces lubricant consumption. The main thing is that such semi-synthetics are allowed for use in a particular internal combustion engine and comply with the recommendations of the motor manufacturer.

Valve stem seals (valve seals, oil seals) are also an element, problems with which increase the oil appetite of the unit.
At the same time, for many ICE replacement caps can be made without removing the cylinder head, the cost of the spare part is very insignificant. Lubricant consumption after replacement in some cases is significantly reduced.
The main reason for the failure of valve seals is their drying and hardening, since the elements are made of rubber. Also, seals can be influenced and unsuitable for engine oil aggressive to rubber.

Wear of piston rings is often similar in symptoms to their occurrence. If in the first case the rings need to be changed, that is, disassembly and repair of the internal combustion engine will be required, then in the second case, the piston rings can be decarbonized.
Simply put, the accumulation of soot and coke does not allow the ring to move in the groove, that is, the rings are stuck. A decrease in mobility means that the ring does not fulfill its function, the oil is poorly removed from the walls and burns out in the combustion chamber.

To solve the problem, there are flushes that are poured into the lubrication system. You can also use flushing oils. A radical way is when a special composition is poured into the candle wells to decarbonize the piston rings.
Each of the solutions has both its pros and cons, however, for a worn engine, in many cases it is possible to reduce lubricant consumption and extend the life of the engine before overhaul.

Increasing the pressure in the crankcase also causes excessive consumption of lubricant. In simple terms, high crankcase pressure causes oil to end up where it shouldn't be.
As a result, the lubricant enters the cylinders through the intake, after which it burns out in the engine along with the fuel. In such a situation, it is necessary to diagnose and clean the crankcase ventilation system.

Problems with the turbocharger also lead to lubrication leaks in the supercharger area, oil also enters the cylinders through the intake, etc.
The solution requires diagnostics and repair of the turbine. In extreme cases, you can replace the turbocharger, while the lubricant consumption will also decrease.

Eventually

The main reason for engine overhaul is the presence of significant defects and damage, as well as high wear of parts and wear on the cylinder walls (seizures, changes in geometry, etc.).

In this case, eliminate the "zhor" of the oil only by decoking, replacement rings, valve stem seals Or switching to a more viscous lubricant will no longer work. Typically, engines with such damage have low compression, start poorly both cold and hot, and lose power significantly.

During operation of the unit, knocks and extraneous noises may be present. As a rule, after disassembly and troubleshooting, the block must be bored/sleeved, the crankshaft must be ground, etc. In other words, it is necessary overhaul.

If the engine is worn out, but it works normally, while the oil consumption is above the norm, then you should not expect an instant increase in lubricant consumption. Lubricant will be consumed more and more, but this problem will progress slowly.
It turns out by adding several liters of lubricant for every 10 thousand km. will allow such a motor to be operated for more than one tens of thousands of kilometers without major repairs (if no other breakdowns occur). At the same time, it is more profitable to top up the lubricant than to repair the motor.

Additionally, the use of a more viscous oil, replacement of valve seals and cleaning of the crankcase ventilation system will help reduce overall lubricant consumption and the cost of maintaining and servicing the internal combustion engine.

At Russian club forums and in in social networks relatively recently, alarming bells began to appear about the reliability of the 2.0-liter KIA / Hyundai G4KD engine, associated with the appearance of knocks in the cylinder-piston group (CPG). At the same time, problems with these engines are not heard in Belarus. What is it - the features of Russian exploitation, as some say, or is it a technological miscalculation? To find out, abw.by journalists assembled several cars and sent them for endoscopy at the CPH.

To begin with, the G4KD (Theta II) and 4B11 "clone" engines are built on the architecture of the Global Engine Alliance - an alliance created by Chrysler, Mitsubishi and Hyundai, but at the initiative of Hyundai. Each company made some adjustments for its brand, but the architecture remained the same. The main part of the development was carried out by Hyundai.

The motor is completely aluminum, contains four valves per cylinder, two camshafts in the cylinder head (DOHC), as well as a variable valve timing system with electronic control MIVEC (intake and exhaust). Accordingly, on Korean cars, the letter designation is G4KD, on Japanese cars - 4B11. The motor was installed on KIA Cerato, KIA Optima, KIA Sportage, Hyundai Elantra, Hyundai ix35, Hyundai Sonata, Mitsubishi Lancer Mitsubishi Outlander, Mitsubishi ASX and numerous American-made Chrysler and Dodge models.

Based on this unit, the G4KE (Theta II) / 4B12 engine with a working volume of 2.4 liters was created. In addition, on the basis of 4B11, a turbo version 4B11T was created for sports Mitsubishi Lancer Evolution and Mitsubishi Lancer Ralliart.

“The owner of a non-warranty KIA Sportage recently contacted me,” says a car repairman from Minsk. “The car arrived from Russia a year ago, there are all service documents - it was serviced at a dealer. Here the owner did not drive even 8,000 kilometers. First, the owner went to a Hyundai dealer, where they listened to the car, they said that the piston was knocking, they say, bullies, remove the engine, sleeve, change the piston - we are aware of the problem ... We did not believe it, we went for endoscopy. It turns out that the guys from Hyundai were right What I saw is normal for old motors with mileage of 400-600 thousand, working for years on mud, with a holey toe instead air filter, but not on a four-year-old KIA with a careful mileage of 120 thousand. The walls of the cylinder are scuffed, long, plentiful and ugly. It is still shallow, as it started pounding recently, about 500 kilometers ago. Compression test showed 13-12-13-13. That is, the motor is still "alive", but in the second cylinder the pressure is already falling. Another 10 thousand kilometers, and it will consume oil for waste and "breathe" into the oil filler neck. After 50 thousand, it will build and "die". If it doesn't jam earlier."

Having removed the pan and found metal powder in it, the motor was dismantled and disassembled. It turned out that scuffs are present in all cylinders on the front and rear walls. In this case, the most damage is in the second, third and fourth "pots".

Needless to say, the pistons suffered as well. After digging around on the Internet, we found out that the case is not at all isolated.

There are already 640 (!) pages of discussions on this issue on the Russian forum of the KIA club, on drive2.ru there are many cases of problems with the G4KD CPG, and on YouTube there are suspiciously many videos about teasing and knocking Korean motor. Symptoms are as follows: in the period of 50.000-150.000 km, the engine has knocks "on the cold". The noise gets louder as the car gets warmer and stops disappearing as it warms up. An autopsy shows the presence of scoring on the "skirts" of the pistons and cylinder walls. And it doesn’t matter where the car was serviced, at a dealer, at third-party service stations or in garages.

Interestingly, a recall campaign was even carried out in the USA, affecting half a million (!) Cars with engines of the Theta II series, which includes the motor we designated. In addition, there was a campaign to extend the engine warranty. But a slightly different problem was stated there, connected with the blocking of oil channels by metal shavings, which led to oil starvation and engine shutdown.

Nevertheless, a large number of Korean cars with these engines have been sold in Belarus, and it seems that little is heard about the problem on our forums, unlike Russian forums. Initially, abw.by learned about the issue from a story with KIA engine Sportage from a Minsk auto repairman: it seems that the mileage is small, and the engine has already required repair due to scuffing.

To find out if these problems are far-fetched, abw.by contacted the KIA Sportage club.

In total, four cars with knocking engines were found in Minsk (in two cases, the knocks were already “hot”), of which three cars eventually participated in our “dismantling”. They also invited the owners of two cars with a mileage of 70,000 and 140,000 km, who did not complain about knocking.

There were problems with the endoscope. "Videomaster PRO" sent from Russia does not see the cylinder walls. It turns out that there are no endoscopists in Minsk. There is only an individual entrepreneur, an experienced auto repairman who is engaged in engine endoscopy. By the way, a car was diagnosed with him a month ago, the internal contents of the engine of which are shown at the beginning of the article.

The endoscope at the master is a special medical one. The probe can be rotated in any direction and bent with special "twists". The cylinder walls are very visible. But the problem is that the device does not take a photo. There are two more Chinese electronic endoscopes in service, but there were problems with them in the process of work. In general, we look into the cylinders with a medical optical endoscope.

The first vehicle inspected in 2011 has already covered 87,000 km. Bought new from a Belarusian dealer, after which it was operated by one owner. After the end of the warranty, there were knocks "on the cold". Over time, they were also present after the engine warmed up, however, noticeably quieter. At the same time, before warming up the engine, small vibrations began to be felt.

The day before the experiment, the owner visited a service station of an official KIA dealer. The "officials" did not have an endoscope, but the mechanics by ear determined that there was a badass in the cylinders. Like, this is a known problem, it is necessary to open the engine and change the cylinder block at a cost of about $4,000.

The owner claims that he drives calmly, the first kilometers he presses the "gas" carefully. The car is regularly serviced at the dealer. Moreover, he even reduced the maintenance interval from 15,000 to 10,000-12,000 km. The oil recommended by our dealer is poured into the crankcase - Motul 8100 5w30.

We remove the coils, we take out the candles. And we see that the insulators of the candles are broken. Interestingly, this pattern was observed in all inspected Sportage, where NGK candles were used.

Moreover, it even breaks through candles that were replaced less than 10,000 km ago. The regulation for their replacement is as much as 30,000 km. A lot of. But there were whole Boschs on one car, so, most likely, it was the candles.

We look into the cylinders with an endoscope - we find strong scuffs in the second and third cylinders, which in total occupy almost 2/3 of the entire circumference on both sides. In the fourth, there are fewer of them, but they are there. The first cylinder is clean. According to the auto repairman, he did not see scoring in the upper part of the cylinders, which indicates that the piston "skirt" leaves scratches.

Looking ahead: soot on the bottom of the pistons is found in all machines, somewhere less, somewhere more. The master qualifies the amount of deposits as "average", but on these runs there should not be such a picture at all.
What's next? Over time, the problem progresses. Knocks will intensify, a strong maslozhor will begin. After a while, the engine will simply stop starting. Expensive engine repairs (replacing the cylinder block or sleeve) can no longer be avoided. When exactly this will happen is difficult to say.

Next car 2011 onwards was also bought in Minsk. At the moment, the mileage is 109.000 km, the warranty is over. The owner is concerned about knocking "on the cold". The car was serviced on time, in the cold it warmed up for a short time, the driving style is calm. Total and Zic 5w30 oils were used. The dealer stopped servicing the car after the third MOT.

However, we listen - the knock is perfectly audible and "hot". Of all the machines here, we heard the loudest and most obvious knock. But even it is not audible in the cabin after warming up.

As expected, seizures were found in all cylinders. Moreover, the most problems are in the second and third, where the bullies are located over a large area around the circumference of the front and rear walls. There are fewer problems in the first and fourth cylinders, although the seizures are concentrated in a relatively small area on the side of the exhaust manifold, but they are very deep. Nagar on the bottom of the pistons of the engine of this machine is the most. In general, the most advanced option. But, according to the owner, there seems to be no oil zhora yet.

On knocks owner next car didn't complain. The mileage is only 76,000 km, the year of manufacture is 2012, the owner bought it in Russia when there were 42,000 km on the odometer. Service book with marks on the passage of MOT available. In Russia, Shell 5w30 oil was poured every 11,000-12,000 km, in Belarus, Kroon-Oil 5w30 oil is changed at an unofficial service station every 7,000-8,000 km. There are orders, orders, original spare parts were used, so the owner hopes to maintain the guarantee in Russia.

There are no scuffs in the first cylinder, but strong scratches were found in the fourth in a small area on the side of the exhaust manifold. In the second and third - small badass on the release side. The owner did not complain about the knocks, but the minder still heard small "snorts" "on the cold". There is no oil consumption.

The next car arrived from Russia in 2015. At the time of purchase, the mileage was 86,000 km, now 115,000. Knocks after starting the engine appeared when the owner read the forums. Yes, yes, perhaps many of them simply do not hear.

The presence of problems in the cylinders was confirmed. On the walls of the second and third cylinders - medium scuffs from the side of the exhaust manifold. The first cylinder is clean, the fourth has a couple of scratches on the back wall. There is not much Nagara relative to other cars, but still clearly not at 115,000 km of run.

It was this car that the journalists tried to shoot with Chinese USB endoscopes. The first saw only the piston, the second nevertheless recorded vertical scratches on the cylinder wall. True, we managed to turn the camera at a small angle, so the wall is visible only at the very bottom. After five minutes of trying, the probe overheated and the device turned off forever.

By the way, pay attention to the ends of the body of the candles. It is at the second and third candles that carbon deposits are noticeable. So, if you suspect a G4KD is bad, but you don't have an endoscope, you can try to unscrew the plugs and look at the ends of the case. Black deposits will indicate that not everything is in order in the cylinder-piston group.

In general, the car is still driving, how much more it will drive is unknown, but the problems have already begun.

Black Sportage 2012 onwards ran the most - 140,000 km, bought with a mileage of 40,000 km in Russia. Almost nothing is known about the service there. The first drained oil surprised the owner: in appearance, either it had not been changed for a very long time, or it was counterfeit. The sticker says that Shell oil was poured. After purchase, the owner uses Zic 5w30. A black crust of deposits formed on the dipstick - the owner had to clean it off for a long time. The engine sounded very loud, but after service it began to work normally.

In Belarus, the car was serviced properly and in a timely manner, but the owner admits that he likes to press the gas pedal well. True, it does this only after the engine is fully warmed up, before that it drives carefully. Auto start is also installed, so the engine warms up for some time at idle before starting.

The owner did not report any extraneous sounds, it was a completely random car, but "cold" knocks are still audible.

We looked at the oil level, figured out what it was like 5000 km ago - a small consumption is still present, about 200-250 g per 5000 km.

There is only one scratch on the first cylinder. The second cylinder on the exhaust side is medium scoring, and the same as on the previous car. In the third cylinder, medium scratches are located on both sides, in the fourth - only on the back wall, but deep enough. Seizure angle - 15-20°.

There are carbon deposits on the ends of three candles, except for one - the first cylinder, on the wall of which there is only one scratch.

What is the result? We dismantled one engine with our own eyes. Examined five more motors - badass were found in all. In three out of five cases, the owners reported the presence of knocks - we took these machines for endoscopy specifically to find out the cause of the knocks. The other two were chosen quite randomly, the owners did not talk about knocking or any problems.

To be honest, it is strange that all three machines with the declared presence of extraneous sounds will have any problems. After all, anything can knock or not knock at all. The car enthusiast can take extraneous sounds the usual chirping of injectors, problems with the timing drive or the operation of unadjusted valves, since the G4KD does not have hydraulic compensators, the valves need to be adjusted. But no, there are bullies in three cars. In addition, they were found in cars whose owners did not hear any knocks ... And another car with a knock did not reach the endoscopy. In general, this is surprising.

No regularity could be identified. The crankcases for these engines are different: there are both 4-liter and 6-liter ones. Mostly cars were inspected. filling capacity 6 liters, but this is unlikely to affect anything. Oils were used in a variety of ways. Maintenance, as the owners assure, was carried out only according to the regulations, and some of them reduced the oil change interval. Two cars were bought in Belarus, four were brought in during the favorable exchange rate of the ruble from Russia. Some cars were serviced at official dealers, there are service documents, others - at unofficial service stations. "Automatic", "mechanics"? Doesn't matter.

The only thing that has been found is different machines bullies develop with different "intensity". On one of them, at 115,000 km, the onset of problems was diagnosed, and the second at 87,000 km will soon need repairs. Also, judging by the reviews, the problem did not affect Mitsubishi owners, under the hood of which a copy of G4KD - 4B11 is installed. At least nothing is heard about it.

There is an opinion that the problem lies in poor-quality service. Russian cars, counterfeit oil, bad gasoline and aggressive driving, especially "cold". Of course, illiterate operation exacerbates the problem, but if it were the main reason, then already half of Belarusian and Russian cars would be in line for engine overhaul.

You can guess about the reason indefinitely, besides, we are not KIA or Hyundai engineers, we have no statistical data. But there is an assumption by experienced car repairmen that the fault is in the calculation of thermal expansions. It seems to us that the version looks very convincing.

“When designing any engine, the coefficients of thermal expansion of the body are calculated and selected,” says auto repairman Alexander. “In this case, most likely, we are talking about wrong selection thermal gap in a pair of "piston - cylinder" or the wrong choice of piston material and its shape. When the engine is running, especially in an increased speed range, the oil film is shed from the cylinder walls with the transition to semi-dry friction. The consequence of such engine operation is scuffing or "sticking" on the cylinder walls. An increase in clearances in the CPG assemblies due to semi-dry friction causes piston distortion and the occurrence of knocking in the engine caused by the impact of the piston "skirt" when shifting against the cylinder wall. The situation is aggravated by the high degree of forcing and the temperature regime of the engine, the visually insufficient area of the water channels of the block or the insufficient efficiency of the water pump. This version is supported by the fact that the second and third cylinders are always the most damaged, that is, the most heat loaded at a distance from the water pump. Based on the foregoing, most likely, there is a constructive miscalculation.

Can misuse of the vehicle cause such serious engine problems? No. Driving on a cold engine may exacerbate the problem, but cannot be the main cause of the problem. In the world practice of engine building, there are a lot of engines with aluminum blocks, and there are no such problems with cylinder walls. For example, the Renault/Volvo B5254 internal combustion engine or the B6284T turbocharged six-cylinder version. The manufacturer lays down the tolerance when calculating the CPG, as well as the absence of the need for special engine running-in after assembly.

Does the quality of fuel and lubricants affect the occurrence of scuffing in cylinders? No, it doesn't. The presence of at least one knock sensor in the G4KD injection system will prevent the engine from running at fuel mixture, causing destructive detonation due to low-quality fuel. The nature and type of wear cannot be caused by detonation in any way, since the "skirt" is damaged, and not the piston crown. There are no melting, bursting rings and inter-ring bulkheads. fuel quality and untimely replacement expressed in the form of tar / varnish deposits on engine parts and cause premature wear of the crankshaft liners, “bedding” of the rings and increased oil consumption. There were no such problems prior to the machine being repaired."

Often, oil nozzles are provided in engine blocks, which are designed to pour oil on the pistons from below, thereby cooling them, as well as improving cylinder lubrication. There are no such nozzles in the atmospheric version of this engine, they are only in the turbocharged version of the Japanese 4B11T, as well as in all diesel engines that are installed on the Sportage. Some motorists believe that their absence exacerbates the situation with G4KD - the piston overheats, which leads to a decrease in clearance.

True, there are engines without oil nozzles, which at the same time do not have problems with scuffing. It’s hard to say whether it’s the injectors or not, but if you wish, you can probably embed them into the block during a major overhaul. Also, perhaps, the installation of an oil-to-water heat exchanger from the "older" G4KE engine can help, since insufficient oil circulation "in the cold" in winter also aggravates the situation. True, we did not carry out any calculations and examinations, so all this is just an assumption.

How to solve the problem if the engine knocked and began to consume oil for waste? Two options are available: either replacing the cylinder block, which is very expensive, or lining the block, which is also expensive, but at least makes sense. The second option is the most common. Standard pistons and rings, liners (fit from Toyota), a set of gaskets and other necessary parts for repair will cost, as we calculated, about $ 1000. With work and other trifles, a tidy sum comes out: for example, for Sportage repair from the very beginning of the article, the owner gave $ 1,750 - a lot. At the same time, no one knows how long the motor passes after the sleeve, there are enough nuances here, hardly as many as the factory engine. If the car is under warranty, you are saved: there is a chance that the unit will be replaced under warranty.

Replacing the unit with a contract one? Also an option, but they are not particularly on sale yet. And if they appear, then we recommend buying such a used unit only after endoscopy of the CPG.

It is not yet known whether this is a massive problem, as journalists do not have statistics from the automaker and technical expertise. So far, only isolated cases have been recorded in Belarus.

But in any case, you need to be guided by a number of recommendations. quality oil change at least once every 10,000 km, pour only 95th gasoline into the tank. Forget about traffic light races forever - this motor, apparently, does not like heavy loads. It is important to drive carefully until the engine reaches operating temperature. At the same time, it’s also not worth driving “in tightness”, but at the same time, the “gas” pedal must be literally stroked. You need to be especially careful in winter, it is recommended to warm up the engine before starting or install an autonomous heater.

And what will the representatives of the exclusive distributor of the KIA brand in the Republic of Belarus of the company "Avtopalas-M" say about this?

"Our car service center received single calls on the specified problem with the G4KD engine. Basically, they were related to non-compliance with the rules for operating the car: harsh operation, ignoring winter conditions, using low-quality fuels and lubricants and fuel, etc. Almost all calls are from legal entities, from which such an attitude towards the car prevails.

Warranty obligations are always fulfilled if the customer's claim is justified. In particular, we generally cannot prove that the vehicle has been subjected to severe use, such as high revs on a cold engine, then the vehicle assembly must be replaced under warranty. At the same time, there were very few such cases for this engine. There can be no talk of mass character.

We recommend that all car owners carefully read and follow the operating instructions, carefully follow the recommendations of the masters, use only high-quality fuels and lubricants. This advice is universal for owners of any cars with any motors.
Are there any problems with the new generation of crossover? Said 2.0 engine was used for previous Sportage models. New model The Sportage QLE, which has been supplied to Belarus since May 2016, is equipped with a new engine."

Hyundai AutoGrad LLC also says that there are isolated cases of bullying in the engines of their Hyundai ix35. Perhaps that is the way it is.

We won't be 100% sure yet, but the G4KD story is strange. Yes, six cars are a drop in the sea of cars sold with this engine (not only KIA Sportage), we really have a lot of them. The Minsk club of Sportage fans has as many as 50 cars with mileage in the region of 100,000 km. And so far none of them have been overhauled, most owners do not complain about knocking. So far, no one is going to change cars in the club either.

But such noise on the Internet arises for a reason, and the results of our endoscopy of five motors and disassembly of one, to put it mildly, are surprising. In general, time will tell.

The second generation Kia Sportage was released in 2004 and received the designation KM. The car was a front- or all-wheel drive five-seater D-class crossover, sharing a platform with its twin brother. Hyundai Tucson. The Sportage received a minor facelift in 2008. The assembly of the crossover was carried out at home - in Korea, as well as in Slovakia and Kaliningrad.

Engines

The range of engines is represented by aspirated petrol - four-cylinder G4GC (2.0 l, 142 hp) and six-cylinder G6BA (V6, 2.7 l, 175 hp), as well as a turbodiesel - D4EA (2.0 l, 112 hp).

Gasoline engines are considered very reliable. Timing belt drive, the replacement of which is prescribed every 90,000 km. When operating a car in difficult conditions, it is better to reduce this period to 60,000 km.

in 2 liter petrol units there are no hydraulic lifters, and the valve clearance is adjusted by replacing the shims. A feature of the youngest of the gasoline ones is a soft tapping after starting a cold engine, lasting no more than 5-10 seconds. Such a phenomenon is not a defect, and in some cases the noise can be eliminated by selecting the viscosity and brand of engine oil.

The flagship 2.7 L has virtually no weaknesses. If you do not save on oil, then it will serve faithfully for a long time. With a run of more than 90 - 100 thousand km, tapping of hydraulic lifters may appear.

Diesel CRDI is somewhat capricious, but, first of all, this is due to low quality diesel fuel. The timing drive, as on gasoline units, is a belt drive with a recommended replacement interval of 90,000 km. The resource of fuel injectors is more than 60-100 thousand km. However, for some they go over 160,000 km.

After 80 - 90 thousand km, the receiving grid of the fuel pressure sensor may become clogged with metal products of the natural wear of the fuel pump. This leads to unstable operation of the diesel engine - it can stall.

Some have encountered such a phenomenon as engine freezing after starting a warm engine. In addition, the diesel engine may not start on the first try or stall immediately after starting. After a successful start, the speed hangs at around 500 rpm for a few seconds, not responding to pressing the accelerator pedal. After a short time, the speed increases to normal values. idle move and the engine continues to run normally. No clear reason for this "phenomenon" has been identified. In some cases, the disease is caused by clogged fuel injectors, after washing which everything returns to normal. This is also possible with a decrease in the operating voltage supplied to the computer, which happens when the battery is discharged - the computer reboots and freezes.

AT very coldy"Tired" glow plugs can cause difficulty starting, which is possible with a run of more than 90 - 100 thousand km. Be careful when changing spark plugs. With long runs, they “stick”, and haste can lead to their “bummer”. In this case, you will have to drill out the remains of the candle with the removal of the cylinder head.

The turbine runs at least 100,000 km. When oil appears in the inlet, do not rush to change it. A turbine from an authorized dealer will cost 55,000 rubles, plus 5,000 rubles for the work of replacing it. This unit can be purchased from intermediaries from Korea for 23,000 rubles, and repair of the turbine will cost even less - 15 - 16 thousand rubles.

Transmission

The Sportage was offered with both manual (manual) and automatic transmission gears (automatic transmission).

The manual transmission clutch remains operational for at least 140 - 150 thousand km. Only tough operation of a crossover can reduce its resource to 70 - 90 thousand km. Some owners complain about the appearance of small jerks and jolts when shifting and poor 2nd gear. There is also such a phenomenon as a metallic crack during acceleration “in tightness”, which disappears with increasing speed. In most cases, replacing the clutch assembly helps get rid of this.

After 150-200 thousand km, some owners were faced with the repair of a manual transmission. Usually the input shaft and the 5th gear were worn out. Symptoms: howling and knocking out the 5th speed. A set of spare parts will cost 17,000 rubles, and for work in the service they will ask from 16 to 50 thousand rubles.

Automatic transmission, as a rule, does not cause serious complaints. A small proportion of owners complain about the appearance of shocks when switching the box from 2nd to 3rd or 3rd to 4th with a run of more than 80 - 100 thousand km.

In everyday condition Sporteydzh front-wheel drive. On the all-wheel drive version, the rear axle is connected, if necessary, using an electronically controlled clutch. Owners of Kia Sportage 2 should not forget that in their hands is just a crossover, and not real SUV. The clutch is quite capricious and does not like overheating, so it is better to avoid prolonged slipping.

Signs of clutch failure are jolts when reversing and a “screeching” sound from behind. This can happen both with a run of 40 - 50 thousand km, and after 100 - 120 thousand km. The cost of the complete clutch is about 50 thousand rubles. Coupling failures are caused by bearing failure due to a weak seal, which wears out quickly and allows dirt to pass through. The cost of a bearing is about 500 rubles, an oil seal - 200 rubles, work - about 2000 rubles.

On crossovers of 2008 of the Slovak assembly, due to a poor-quality batch of drives, the right CV joint wore out by 30 - 50 thousand km. The cost of replacing at an authorized dealer is about 15,000 rubles.

Chassis

As experience has shown, the operation of the suspension is quite noisy. She starts knocking already at a run of more than 50 - 60 thousand km.

Knocks in front are caused by struts and stabilizer bushings. With a run of more than 40 - 60 thousand km, the front shock absorbers also begin to knock, but at the same time they do not flow and do not lose their performance.

Squeaks in the back cause stabilizer bushings rear axle. In this case, treating the bushings with silicone grease will help for a while. This shortcoming characteristic of crossovers of the Kaliningrad and Slovak assembly. It is better to replace it with an analogue from Hyundai Tucson, which will allow you to forget about the squeak for 70-80 thousand km.

Rattles in the rear can be caused by soft rubber on the mounts rear pillars- appears in cold weather. Replacing the racks themselves does not lead to a positive result, it is necessary to install more rigid supports. Often, the salent blocks of the subframe on the Korean assembly Sporteydzhah knock.

Not uncommon for the Kia Sportage is a quick departure of the camber adjustment with the car moving to the right. What caused this, no one can say for sure.

Hub bearings may require replacement after 90 - 120 thousand km.

After 70 - 90 thousand km, it may start to tap steering rack. Its cost at the officials is about 25 thousand rubles, the original from intermediaries is 17 thousand rubles. Do not rush to change the rail. The reason for the knock is the wear of the inner bushings, which can be replaced by purchasing a repair kit. Tie rods and tips go, as a rule, at least 100,000 km.

The braking system is also sometimes inconvenient. Many owners consider it insufficiently effective. Some have encountered the following feature of the brakes - wedging in the pressed position. After releasing the brake pedal, it does not fully return to its original position, while the pads remain compressed. This manifests itself with a run of more than 20 - 50 thousand km. The official dealer cannot solve this problem, perhaps the reason lies in the check valve of the master brake cylinder.

Front brake pads go on average 40 - 60 thousand km, rear - 70 - 100 thousand km. 60 - 100 thousand km will serve the front brake discs.

Body and interior

The paintwork of the crossover body is not good enough, especially on specimens assembled in Slovakia and Kaliningrad. On cars older than 2 years, paint swelling on the 5th door is possible. Weak spots on the door - under the glass and license plate. glass hinges back door often climb after the first winter. The authorized dealer will replace them under warranty. The cost of loops is about 2000 rubles and 200 rubles - work.

An unpleasant creak can be emitted by an external plastic lining at the bottom windshield over the "frill". With a run of more than 40 - 50 thousand km, individual elements of the plastic interior trim sometimes begin to creak, especially in cold weather.

Some notice during acceleration a monotonous chirping behind the instrument panel. It occurs only on cars with manual transmission. The source of the sound is the coils of the clutch pedal return spring, itching when touching each other.

The leather trim of the steering wheel begins to peel off already with a run of more than 15 - 20 thousand km, mainly on fresh cars in 2010.

Poor positioning of the driver's seat up and down lever causes the driver's seat to lower constantly. The lever is located too high - on the same level with the bottom cushion of the chair. During landing, the driver involuntarily presses down on the lever, lowering the seat. Some got rid of the disadvantage by setting the lever "beak" down.

Conclusion

Front-wheel drive 2-liter crossovers consume about 12-13 liters of gasoline in the city and 9-10 liters on the highway. The same amount is asked for all-wheel drive cars with manual transmission. With automatic transmission in the city, consumption rises to 14 - 16 liters, on the highway it remains about the same - 9-10 liters per 100 km. The flagship 2.7 liter in the city consumes up to 15 - 17 liters, and on the highway - 10 - 11 liters. Diesel is much more economical - up to 12-13 liters in the city and 7-8 liters of diesel fuel on the highway.

What is the result? Good engines, but a weak clutch and booming suspension. And with high mileage, problems with the manual transmission began to be observed. This is an average car for every day to conquer hard pavement without outstanding outstanding abilities.

Childhood diseases KIASportageIII (2010 - 2014, restyling 2014 - 2016).

In 2010, the third generation KIA Sportage was released. The car was produced at the factories of Korea, Slovakia, Russia. Russian assembly takes place for a "tick" (to reduce customs clearance). Initially, all delivered vehicles are assembled in Slovakia, then disassembled and sent for SKD assembly in Kaliningrad.

Engines for the Russian Federation: petrol 2.0 (150 hp, acceleration to 100 km / h - 10.7 seconds, combined consumption - 7.8 liters per 100 km). Diesels: 2.0 (136 hp, up to 100 km / h in 11.1 seconds, average consumption - 5.5 l), 2.0 (184 hp, up to the first hundred - 9.8 s, city / highway consumption - 6.1 l). There is one interesting engine for domestic market Korea - 2.0 liter turbocharged gasoline (261 hp, up to 100 km in 6.5 seconds, average consumption - 10 liters), was imported by "gray dealers" and 150 hp was indicated in the TCP. (in the database of the customs of the Russian Federation, another gasoline version does NOT exist).

Transmissions: mechanics for five or six gears, 6-speed automatic.

All-wheel drive is implemented using a clutch, ground clearance- 172 mm (which is not serious for our roads), 5 safety stars according to the EuroNcup rating.

Basic equipment: ABS, 2 airbags, 4 el. window regulator, el. adjustable mirrors with heating, air conditioning, board - computer, front armrest, alloy wheels with a diameter of 16, rain sensor, AUX / USB.

AT maximum configuration: system exchange rate stability, 6 airbags, hill-climb assist, a roof with a panoramic view, leather interior, keyless entry, rear view camera, parking sensors, automatic parking, tire pressure sensors, cruise control, heated steering wheel and all seats, el. seat adjustment, el. folding mirrors, heated wipers, AUX / USB navigation system with Bluetooth, bi-xenon headlights.

Sores of KIA Sportage 3 or what to look for when buying a used one.

Koreans modify their cars during operation by the consumer. For many sores, they issue service bulletins -. Many problems have already been fixed by the owner himself under warranty. Little trick! If childhood illnesses surfaced in the diagnosis, bargain. Then write - call the KIA representative office and they will probably be eliminated for free.

sores	Solutions
Suspension
knocking (felt on the steering wheel) with small irregularities	replacement: steering tips, right rack bushing (for fluoroplastic), lubrication and installation of a gasket in the power steering clutch (cut from a piece of rubber - diameter 22mm), rack and amplifier - changed under warranty
shock absorbers often leak and knock (in winter)	installation, NOT original racks - Sachs
sagging rear springs	installation of reinforced springs - “suspension from Tolka” (DO NOT sag!)

doors do not close the first time, the reason is door seals, for the Russian market they are more “thick” (in order to improve tightness in winter)	make holes in the seals
cracked glass in the heating zone of the wipers	remove the fuse - F15, (15A)
Electrician
often the battery "dies" on cars with DRL	disconnect the battery integrity sensor (located on the negative terminal)
constantly "beeping" rear parking sensors	replacement under warranty or non-original installation (for example, order in China)
error - P2562, drop in dynamics - development of the turbine damper rod (diesel)	calibrate the rod (described in detail at the kia club)

lock knock rear seat, from bad roads the bracket unwinds	put engraving washers under the bolts of the lock bracket, grease with silicone
the leather on the steering wheel is peeling off	exchange under warranty or alter
cracking "skin" on the side support of the seats	warranty or replacement
armrest creak	glue around the perimeter with “modelin”, especially the latch hook
stove whistle	change the cabin filter more often
Engine
flowing oil supply pipe to the turbine (diesel)	replace the rubber part of the tube (oil-resistant hose, diameter - 6mm) - tighten with clamps
knocking - seizures in the cylinders, the G4KD engine (gasoline 2.0 - 150 hp), if NOT warmed up, drive actively (especially on the "cold") - the pistons overheat, there is no forced cooling - a design feature	before buying - be sure to check with an endoscope
Transmission

Kia Sportage third generation can be called one of the most liquid used cars. Used Korean crossovers find new owners very quickly. But is it possible to call the third generation Sportage also one of the most reliable "rogues"? big question! No matter how much the owners of the Korean crossover would like to admit this, the car is not without serious design flaws.

Possible problems with the body

To quality paintwork Kia Sportage, however, no one has any complaints. Even on the oldest specimens, foci of corrosion are extremely rare. Nevertheless, it is worth approaching the inspection of the body of the car you like very seriously before buying. The fact is that the cost of the original body panels for the KIA Sportage is quite high. So restoring a car, even with seemingly minor damage, can be very costly. It also seems surprising that there are not so many more affordable body parts from third-party manufacturers on the market. Yes, and their quality is a big question.

When inspecting the Sportage, it does not hurt to check the performance of the front and rear optics. and lanterns on the Korean crossover burn out quite often. And the worst thing is that the weak link in the car's electrics has not yet been found. Another weak point of the Sportage of the first years of production is the driver's doors, which tend to sag after a run of 30-40 thousand kilometers. Fortunately, they can be adjusted quickly enough.

Do not be too lazy when inspecting the car to check the presence of a side seal on the left wing. On many cars, it has already been lost, which is fraught with moisture getting under the hood, which, under unfortunate circumstances, can flood the engine control unit. And if you let everything take its course, then very soon you will have to spend money on a new block.

From time to time, owners of a used KIA Sportage will have to save their money for the purchase of parking sensors, the resource of which does not hold water. It is possible that you will have to spend money on a rear-view camera. Its tightness leaves much to be desired.

What are the problems with the engine

But all these shortcomings are actually not so critical that they refuse to buy a car because of them. Rather, buying a used Sportage will have to be abandoned because of its engine. The two-liter gasoline powerhouse on pre-styling crossovers turned out to be extremely unsuccessful. Not only is it dynamic characteristics leave much to be desired, so also its resource is extremely low. Judge for yourself - already after 100 thousand kilometers in an atmospheric engine, the liners can turn. And worst of all, repairing a damaged engine is extremely difficult and expensive. The choice of spare parts is poor.

In addition to turning the liners, pre-styling owners may encounter flooding of the phase shifter clutch control valves. Most often this happens with a run of 80-100 thousand kilometers. After restyling, the two-liter engine became more reliable. Although it is possible that this reliability is only apparent, since most of the relatively fresh Kia Sportage have not yet managed to roll at least 100 thousand kilometers.

Diesel engines were also offered for the third generation Sportage, which were built on the same base, but due to different turbines, heads and fuel equipment they produced different power - 136 or 184 horsepower. In these power units, as well as gasoline engines, a gas distribution chain drive is used, which has proven to be very reliable. But that's where the positives end. Disadvantages of diesel Kia engines Sportage is enough. The main one is delicate fuel equipment, which begins to fail after a run of 100-120 thousand kilometers. So if you notice that there is more diesel fuel, and a warm car stops starting the first time, then be sure that you are clogged with chips that appeared as a result of high pressure wear. In this case, the piezo nozzles and the pump will have to be restored, which will cost a tidy sum. Buying new parts, of course, will be even more expensive.

The dual-mass flywheel has proven itself not too well on diesel KIA Sportage. He rarely nurses more than 90-100 thousand kilometers. But the turbines on diesel Sportage turned out to be unexpectedly long-lived. They are rarely changed. This is true for glow plugs as well. Owners of diesel crossovers do not face serious problems with the exhaust gas recirculation system.

The reliability of the box and suspension of the third generation Sportage

A manual gearbox in our market was offered only for petrol Sportage. And, unfortunately, there are a lot of complaints about the “mechanics” of the Korean crossover. Due to a manufacturing defect on cars that were produced in 2010-2011, mechanical box gear shifting had to be changed under warranty after 30-40 thousand kilometers. Naturally, the Koreans quickly dealt with the problem that had arisen, but the sediment remained. So if you buy a used Sportage with "mechanics", then it is better to give preference to cars of the last years of production. Or better yet, choose a crossover with an automatic transmission. Unlike the "mechanics" it has an enviable reliability. Sportage owners with an “automatic” will only have to periodically change transmission oil. The replacement interval in our conditions is better to be reduced to 40 thousand kilometers. It is a pity that you can only fill in the box original oil with special Kia approvals. Finding it is easy, but the price tag is not encouraging.

The plug-in all-wheel drive system on the third-generation Sportage has become more reliable than that on its predecessor, but it hasn’t completely eliminated weaknesses. One of them is a splined connection that passes through the transfer case of the intermediate shaft and the right drive. On crossovers that were released in 2010-2011, it wore out literally after 40 thousand kilometers. Fortunately, defective parts official dealers changed under warranty. Otherwise, there are no complaints about the all-wheel drive transmission.

In the suspension of a Korean car, wheel bearings have the lowest resource. On new crossovers, they rarely withstood more than 40-60 thousand kilometers. Fortunately, most Sportage owners have already managed to replace them with more affordable analogues, which, moreover, last longer. Another nuisance that may await the owners of used Korean crossovers, lies in the fact that the camber adjustment bolts in the rear arms turn sour over time. As a result, in worst case the usual operation "dismantling-collapse" can end with the replacement of levers.

But what the Kia Sportage has no complaints about is the steering. And this equally applies to both hydraulic power steering and electric. Did not deserve special criticism and the brake system "Korean". Most crossover owners have already managed to change low-quality factory discs and pads to third-party products, after which they brake system forgot.

It turns out that such a popular third-generation used Kia Sportage in our country cannot boast of high reliability. Moreover, in the first years of the conveyor life, the design of the car was frankly “raw” at all. Then the situation improved significantly, but in terms of reliability, the Kia Sportage did not get close to the leaders in its class. And when buying a used crossover, this must be taken into account. You will have to call in for service on the Kia Sportage a little more often than we would like.
