GMC Yukon Recalls

Ignition Switch

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.

Loss of Power Steering Assist

A fault can develop with the Electric Power Steering resulting in sudden loss of power steering assist, increasing the risk of a crash. Dealers will replace the power steering assist motor kit to correct this concern.

Engine Stalls From Electrical Module Short

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.

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.
GMC Yukon 2002. Started with 3 miles directly from the dealer. Now the mileage is over 334488. Have picture to prove it. Amazing truck! Towed a lot and very strong and reliable. Definitely love it!
