New Generation Kia Sorento does not claim the laurels of an “uncompromising” SUV. But, despite the fact that the frame and mechanical interlocks a thing of the past, efficient pluggable four-wheel drive still remains strong point crossover.

The main task of all-wheel drive in the Kia Sorento is to ensure safety in wet and slippery surfaces. And he copes with this very well. The simplest test for the efficiency of 4x4 operation is a sharp start from a standstill on a wet surface. With an engine that has a torque of 450 Nm, any front-wheel drive car would cause the drive wheels to slide during a sharp start. But this doesn't happen on the Sorento. Not at all sharp pressing gas from a standstill or while moving, the wheels practically do not slip. The rear axle instantly connects to the front axle to help and “push off” from the road, even the most slippery one, very confidently. At the same time, the car also obeys the steering wheel.

Let's figure out how the complete Kia drive Sorento

Another example is turning in an arc at speed, again at wet asphalt. In this case, the system does not spin the inner wheel, distributing torque to all the others. And the car seems to be screwed into the turn, making the maneuver safe. At the same time, the driver feels that the massive crossover obediently turns into turns, just as a passenger sports hatchback would do. It seems that you are such a master yourself. But no, all-wheel drive and smart electronics, quietly intervening, did something for the “master.”

Well, the last exam is on a wet, muddy primer.

We block the distribution of torque between the axles in a ratio of 50:50 by pressing the button under the automatic transmission lever and “go to start”! The lock indicator lights up on the panel and we (according to the official distributor FALCON-AUTO, the system operates at speeds of up to 40 km/h) move forward. If one wheel loses traction, after minimal slipping it is braked while the others help the car get out of this situation. Thus, the car travels several hundred meters until it reaches a more stable surface. It’s not worth driving for a long time through muddy mud - the clutch will overheat and you’ll have to run after the tractor. Despite the fact that the Kia Sorento is an SUV, it’s not worth trying to conquer heavy off-road conditions.

So complete Sorento drive It perfectly helps to cope with wet roads, gives the driver confidence in turns and does not let you down when driving through small obstacles without a hard surface. This is exactly what consumers who mostly drive on the road expect from a modern SUV. common use, regardless of their quality and weather overboard.

This article discusses the most common breakdowns Kia car Sorento with the factory index XM, second generation. Malfunctions of all-wheel drive (AD), as well as body electronics systems, will be described here, problems will be raised diesel engine R 2.2.

Sorento 2 came off production lines from 2009 to 2014. In 2013, the model underwent a minor restyling. XM has been replaced these days new model U.M.

Both the pre-restyling and post-restyling models have weakness in the design of the all-wheel drive system. Moreover, according to statistics, all-wheel drive most often breaks down on Sorento 2013–2014 model years.

Kia Sorento, all-wheel drive does not work

Most common problem is corrosion and complete rotting spline connection between the transfer case and the gearbox differential. This happens on both automatic and manual cars. For the driver this is manifested by the following symptoms: no all-wheel drive (do not spin rear wheels), the PP malfunction lamp does not light up, there are no errors, cardan shaft does not rotate when the front wheels rotate.

1: TORQUE CONVERTER HOUSING, 2: DIFFERENTIAL ASSEMBLY, 3: AUTOMATIC TRANSMISSION CASE

If the cardan does not spin, all that remains is to make sure whether it will have to be replaced transfer case. To do this, you need to unscrew it, move it (you don’t have to remove it completely) to the side and inspect the condition of the splines on the transfer case shaft.

The transfer case assembly must be replaced with a new one if wear (A) is greater than 50% of the width of the spline tooth (B).

After you have purchased all the spare parts necessary for repairs, you can begin to remove and disassemble the gearbox (gearbox). After all, the differential assembly, which will have to be replaced completely (or partially), is located inside the gearbox.

The entire repair usually takes about 5-7 hours of working time.

Repair or replacement of all-wheel drive clutch, Sorento XM F/L

On restyled models, those produced in 2013-2014, the all-wheel drive clutch often fails. It is a fairly simple design, consisting of a clutch pack and a pump that creates pressure of the working fluid to engage these clutches.

If the clutch breaks down, the all-wheel drive fault indicator appears on the instrument panel. The error codes are: P1831 Clutch Thermal Overstress Warning, P1832 Clutch Thermal Overstress Shutdown. At the same time, the cardan rotates when the front wheels rotate, and on rear axle the moment is not conveyed.

This problem usually manifests itself in the following way: when the PP is actively used, a noticeable impact occurs in the transmission and all-wheel drive disappears. The cause of the breakdown was a rupture of the factory weld on the hub of the clutch pack. The hub itself does not come as a separate spare part. You have to change the clutch assembly.

The price of the coupling is about 30,000 rubles, with officials it reaches 54,000 rubles. Coupling number 47800-3B520.

Fortunately, there is a possibility of repair. Moreover, this repair is not complicated. After removing the coupling, you need to completely disassemble it and weld the cut seam with argon. During disassembly it is recommended to replace working fluid couplings, as well as two coupling seals.

OE numbers: liquid - Ravenol TF-0870, front oil seal - analog Corteco 20026696B.

Rear view camera malfunction

On the Sorento XM, regardless of the year of production, the rear view camera fails. Sooner or later this happens on all cars without exception.

At first, the video signal from the camera may become cloudy or disappear and appear briefly. Next, the camera fails completely.

The reason is moisture ingress and oxidation of contacts. printed circuit board cameras. If the malfunction has just begun to appear, there is a chance to restore the camera’s operation by disassembling it and cleaning the contacts from oxide. To remove the camera, you will have to remove the trunk door trim, and if it is a car after 2013, then also the outer plastic trim.

A standard (original) rear view camera on a Kia Sorento costs about 11,000 rubles. Cat. No.: 95760-2P110

Replacing a rear view camera on a Sorento

Since the original camera is very expensive, it is often replaced with a similar universal Chinese one. The only problem with this is that universal cameras usually require a supply voltage of 12 V, while the original one is connected from 5 V. You can take the plus power from the flashlight connector reverse, and solder the video signal wires to the standard wires.

EGR valve malfunction on diesel Sorento XM

On cars with diesel power unit, at a mileage of about 100,000 or more, a problem with the exhaust gas recirculation (EGR) valve may appear.

This valve is included with all modern diesel engines. It is needed to reduce toxicity exhaust gases, in particular, to reduce the amount of NOx in the exhaust of turbocharged engines.

The USR is solenoid valve, with valve stem position sensor. It stands in the air channel connecting an exhaust manifold with inlet. The EGR has a cooler through which coolant circulates; this is necessary to cool the exhaust gases sent for afterburning. intake manifold and then into the cylinder.

The reason for the failure of the EGR valve is poor quality diesel fuel. It comes into contact with the exhaust, gets very hot and cokes due to the high soot content in the exhaust gases. On long runs The valve stem and disc simply become stuck in soot, which is the cause of error codes P0401, P0402, P0403, P0404.

The logic of the engine control system is such that when any of these errors occurs, the control unit goes into fuel pressure limiting mode. The car does not develop power, the “Check” lamp lights up.

The EGR valve itself costs about 9,000 rubles for the original one. Therefore, before replacing it with a new one, it makes sense to clean it. In 90% of cases this helps.

Despite the apparent accessibility of the installation, it is not always possible to quickly remove the valve. Often it turns sour that it cannot be moved.

After the valve is removed, it must be soaked in injector cleaning fluid or kerosene. With the help of chemicals, all carbon deposits are easily removed.

If EGR error codes still appear after cleaning, you may still have to replace the valve. Catalog numberEGR valve for Kia Sorento 2(XM) 28410-2F000.

As befits a modern SUV, the Kia Sorento sports automatically engaged all-wheel drive, implemented using a clutch manufactured by the Magna concern. In normal mode on dry Kia road The Sorento is front-wheel drive, but with reduced traction the ratio of traction on the front and rear wheels ax can vary from 100:0 to 50:50, respectively. From multiple sensors the electronic unit receives information about angular velocity rotation of each of the four wheels, lateral acceleration, steering angle.

Based on these readings, the electronics redistribute torque between the front and rear wheels to provide maximum directional stability in different driving situations. The system sends a signal to the electric drive, which increases the pressure on the drive clutch pack rear axle, ensuring the transmission of torque to the wheels of the rear axle. The higher generated pressure, the more torque is transmitted to the rear axle.

By pressing the corresponding button in the cabin, the driver can forcibly lock the rear axle drive clutch package, which performs the function center differential. Then the torque distribution is set to 50% on the front and 50% on the rear axle. However, this mode only works at speeds below 40 km/h. If the speed increases above this mark, the system switches to Auto mode, i.e. the clutch package is unlocked, and the torque is flexibly distributed based on the driving mode. But, as soon as the speed drops below 30 km/h, the clutch again blocks the clutches, ensuring equal distribution of traction between the axles.

Compared to Sorento previous generation The transmission has been upgraded, so that the engagement time of the rear wheels when slipping is now only 0.15 seconds. Therefore, according to the manufacturer, the Kia Sorento can handle wet, snowy or sandy roads. By the way, similar all-wheel drive transmission installed on the new generation crossover Kia Sportage, which will appear in Ukraine early next year.
