GMC Yukon XL Denali Problems

Heating and AC Temperature and Air Delivery Mode Door Actuators May Fail

One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.

Air Conditioning Compressor May Fail

A rattling noise may develop from the AC belt tensioner. This can be caused by an internal fault with the AC compressor, AC performance may also be diminished when this occurs. Our technicians tell us that replacing the ac compressor will commonly correct this concern.

The rear window defogger may stop working due to a wire terminal broken off of the rear glass. Our technicians tell us that terminal can be reattached using a special glue or silver solder.

Roof Rail Air Bags May Be Damaged During Deployment

The roof rail air bags may be punctured or torn by the roof carrier hardware during deployment due to being installed without proper reinforcements where they mount. Dealers will replace the roof carrier attaching hardware free of charge to resolve the concern.

Possible Under Hood Electrical Fire

The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.

Possible Service Engine Soon Light, Engine Stalling, or Hard Starting

The RTV seal on the fuel system control modules may allow water to enter into the module. Water in the module can cause a short, which may cause hard starting, a crank-no start condition, or stalling, and the Service Engine Soon light may come on. If the engine stalls unexpectedly, there is an increased risk of a crash. Dealers will replace the fuel system control module free of charge. The recall began on May 18, 2009. The GM recall number is 08411.

I brought my 2001 Yukon XL Denali new and still drive it today. It has 183K+ and is still in what I would call excellent condition. I'm a mechanic and have done all of my own work after my warranty expired. Although, I've had many parts failures (2 x more than my 97 Chevy C1500 PU which I also still drives), I still would rate this vehicle as "good". The largest part replaced was front differen...
