Chevrolet Tahoe 3 / GMT900

The Chevrolet Tahoe is, in a sense, a relic. The SUV is based on a solid base from the “truck” – a full-size GM platform with a frame and a rigid rear axle. But on closer inspection, especially with the top versions, it turns out that the Tahoe is a comfortable and luxurious car. In addition, the tall and heavy SUV (2.5 tons) is quite responsive and holds the road well. Passengers are comfortable in traffic, but large irregularities will not go unnoticed. Simple, clear and convenient are the best words that characterize the salon. In the first and second rows there is a lot of free space above the head and in the legs. There is also a third row of seats, but getting there is not easy. The huge size leaves no doubt that the Chevrolet Tahoe is a very safe car. And it's true. In crash tests according to NHTSA, the mammon-like SUV earned a maximum of 5 stars. The model was assembled in the United States and Russia. In the secondary market, the advantage is for immigrants from Kaliningrad ("Autotor").

Engines

In the arsenal of the model only the classic atmospheric V-shaped eights:

In the secondary market, most SUVs with engines with a volume of 5.3 liters and only a small share are cars with units with a capacity of 6.2 liters.

American engines are very reliable, and the HRM chain lasts a long time. Interruptions in operation can occur due to cracking of the body of the ignition coils or contamination of the throttle. After 150 000 km often fails fuel pump in the tank - there are lapses in the thrust. The cost of the new module is from 17 000 rubles.

Transmission

All engines were combined with a 4-speed automatic transmission 4L60-E, and since 2011 - with a 6-speed 6L80. Both boxes are pretty reliable. Many owners after 120-150 thousand km note the appearance of aftershocks, which are treated by flashing the ECU. Episodically there are problems with the hydrotransformer - vibrations occur. For repairs will need about 40 000 rubles. However, the service machines rarely come, and if there is such a need, the cost of restoration is relatively small. The main thing is to update the oil in the box every 60,000 km and monitor the cooling tubes of the automatic transmission oil. They sometimes begin to leak after 80-110 thousand km (from 7 000 rubles per set).

The all-wheel drive system has four operating modes: 2H (rear-wheel drive), Auto (front wheels are connected automatically using a multi-plate clutch), 4H (clutch locked) and 4L (downlink).

The transfer box is quite reliable, but sometimes the pump damper fails. As a result, the pump starts to knock on the dispensing body and breaks it. With large runs, the drive chain can stretch.

After 50-100 thousand km, it is often necessary to change the worn crosses of the rear driveshaft.

To 100,000 km, individual owners note the appearance of the backlash of the right semi-axle of the rear axle. This is the result of wear of the groove holding the semi-ring. When the backlash becomes critical, then there is a knock - the semi-axis will have to be replaced.

Walking

The front suspension is completely independent on double transverse arms. The top lever is steel, and the bottom is aluminum. The upper ball support, unlike the lower one, changes with the lever (from 9000 rubles) and lasts longer. As a rule, ball wears out after 100-150 thousand km. By this time, the turn and front hubs (from 13 000 rubles) comes.

In Tahoe, three suspension options were installed: conventional, with springs of variable stiffness and active - with electronically controlled shock absorbers and pneumatic elements at the rear. Unfortunately, pneumoballons (from 18 000 rubles) have a relatively low resource - 80-120 thousand km. A faulty balloon forces the pneumocompressor to work constantly, which leads to its premature wear (from 35,000 rubles). Front shock absorbers (from 18 000 rubles) run more than 100-150 thousand km.

Over time, a backlash appears in the lower cross of the steering shaft. Many people prefer not to notice this defect. Fortunately, there is no trouble due to cross-breeding.

Sometimes the body rolls to the driver's side. The difference in height reaches 3-4 cm. The car does not take you anywhere. To eliminate roll, you have to either change the springs or update the control program for body position sensors (if there is an active suspension). Or you have to get used to it and do nothing.

Body and salon

The paint coating of the body is not particularly durable. With age, paint flakes off on the trunk door, chips appear on the bumper, in the lower part of the wings and doors. The room on the frame (on the right side in the back door area) requires additional protection against corrosion.

Top versions were equipped with footsteps with electric drive. Often within a few years they began to creak or peck. The mechanism requires regular prevention: removal, disassembly and lubrication with a mud repellent composition. Otherwise, the hinges wear out, the bracket is destroyed, the drive motor or gearbox fails.

After 4-5 years, the shock absorbers of the trunk door (from 1,500 rubles) are handed over or the external button refuses - water enters the door (from 1,000 rubles). In addition, the contact of the rear window heating falls off. By this time, the trapezoid wipers sour, and its hinges wear out (from 10,000 rubles). Sometimes the door locks fail.

Mirror elements and branded wheel caps are often the prey of thieves.

With age, more crickets appear in the cabin, the steering wheel is wiped, and the paint is erased from the fan control buttons of the climate unit.

Other problems and malfunctions

Problems with the air conditioning system often arise due to rotten tubes of the rear circuit. For repairs will need 16-20 thousand rubles.

Do not differ in durability and sensors of parktronics - often refuses the extreme left (from 3000 rubles).

Sometimes the front shock sensors fail (from 7000 rubles). They are located on the frame behind the front bumper. Moisture enters the sensor body, and corrosion occurs. As a result, errors appear in the airbag control system.

Shows, bargaining and re-registration take time: buyers look, promise to think and disappear. Fair price after inspection closes the auction on the spot. If money is needed urgently, the purchase takes away waiting and repeat displays.
