Chevrolet Tahoe Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Chevrolet Tahoe

The upper dash may crack, most commonly on vehicles in warm climates and exposed to a lot of sunlight. The common repair is to replace the upper instrument trim panel. Information on a technical service bulletin or extended warranty is not available at this time.

The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

The ignition switch actuator can bind causing the ignition switch to stick in the "start" position. If this were to occur the actuator can unexpectedly release, cause the ignition switch to snap back into the "Accessory" position. This would cause the engine to turn off with an associated loss of brake and steering power assist. If these conditions were to lead to a crash the airbags may not deploy as expected. Dealers will inspect and replace the ignition lock housing as necessary to correct this concern.

The chassis electrical module can short due to internal contamination. This can result in the vehicle stalling. Dealers will replace the chassis electronic module free of charge to resolve the concern.

All late model vehicles are equipped with a "Shift interlock" system that prevents vehicles with and automatic transmission from being shifted out of the Park position under certain conditions. Some of these vehicles are being recalled because they may have been assembled with a broken park lock cable or a malformed steering column lock actuator gear. Failure of these components can allow the shifter to be moved out of the Park position with the ignition key removed or in the off position. This can cause the vehicle to roll away unexpectedly increasing the risk of injury or a crash. Dealers will inspect the recalled vehicles and replace the steering column as necessary.

every time i let my tahoe sit over night or about 12 hours the battery is dead there is a slow drain we have changed the battery twice and i cant found where the problem is. but after we jump start it it starts and runs good . just cant figure it out

I purchased a 5.3 L 2 WD LT model with approx 12k miles...it now has 416,000 with orginal drive train. water pump, power sterring and alternator are the only replacements beyond normal maintenence. replaced the original spark plugs at 285, 000 miles and it did not make much difference! I don't even believe it out of a GM vehicle, but glad this one was mine

We have owned this vehicle since 2005 with only two problems: 1. transmission needed to be rebuilt and 2. front upper and lower ball joints and control arms. Otherwise this has been an extraordinary vehicle.
