GMC Yukon Repair and Maintenance

A guide to problems, costs, maintenance and repair for your GMC Yukon

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 power door lock actuators may become slow to operate or stop working completely and require replacement.

The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.

changed gas cap twice, garage replaced vent valve but have code. Do not know where purge valve is located but saw evidence of leaking in the rubber gas fill hose from filler to gas tank. I think I need to replace the filler rubber hose.

I'm a young mechanic and I really need this manual for Cummins QSD 2.0 engine, I can't find it anywhere. So please, who can give me a link to get it?

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.

I've just been told that I need a new transmission. My yukon only has 101,000 miles on it and has been well maintained. Any suggestions of what could be causing hesitation when going 50+ MPH instead of a new transmission? What should the cost be for a transmission?

I've had my 1999 4WD SLT Yukon since it was new from the dealer. I've had some issues over the 12 years. Replaced the air conditioning, fuel pump, water pump, power steering fluid hose, water intake manifold hose, breaks twice, serpentine belt twice. It's got 152,000 miles on it. I consider these fixes fairly normal. I would buy the same truck again.
