What 2005 GMC Yukon Denali XL owners say
Electrical system
While driving I noticed that the speedometer needle was erratic going from zero to 120 MPH. When I stopped the needle was stuck at 30 MPH. At the same time the gear shift indicator light went from dull to non existent preventing me from knowing what gear I was in. This was happening sporadically but now the speedometer needle is always on zero and the gear shift indicator is never lit. I saw online that there has been a recall for the instrument panel for the same speedometer problem I am having but the recall ended with 2004 vehicles even though there is a lot of complaints online with the 2005 models also. I saw a recall (#05023) for the gear shift indicator light. I tried calling GMC to have it fixed and was told it is VIN specific. I explained that the recall did not specify specific VIN numbers. Was rudely told I am out of luck. I tried to address both issues with GMC to no avail. …
While driving on the highway with my cruise control set between 50-70mph, I began noticing my speedometer beginning to jump between 0-120mph causing the limiter to kick in and me losing the ability to control speed. Keep in mind I'm only going between 50-70mph. This later began occurring without the cruise control on. Shortly after this began happening another problem started. Now when the cruise control was set between 50-70mph, the engine would automatically accelerate maxing out the RPM's and sending the vehicle to approximately 80-90mph before I had to hit the brakes or completely cut off the cruise control. Later on when I would set the cruise control the vehicle would begin to jerk violently, revving high then going back to normal before revving high again and me shutting off the cruise control. There was never a check engine light the whole time this was happening. …
Brakes
Was driving about 30mph and hit the brake pedal, the brake pedal went to the floor and we ran into a trailer. The brake lines were rusted so bad that they busted, and caused the brake fluid to leak out. The estimate to repair the brake lines alone is $2800.
Started car in the morning to go to work. As I do every day. Foot on brake as usual, shift to drive, to begin a turn in my driveway, in making the left turn, which is a downward grade, applied brake, which went to floor. No resistance whatsoever, complete failure of brakes. Kept foot on brake and steered up the grade, then put car into park. Got out, opened hood. Checked master cylinder- no fluid visible at usual line. Checked under vehicle, brake fluid trailing on driveway under path of vehicle, and slow drip from under forward front driver side . Brake lines and connector completely corroded and rusted. Had I been on the road I would have been unable to stop, vehicle is driven by my son as well. Our lives and those of others in the vehicle as well as others that mead been in our path were clearly in danger. This problem should not occur, and is completely unacceptable.
Engine & cooling
The vehicle's engine shuts off while driving. Without warning. This happens at various speeds. Loss of brakes and power steering occurs after engine shuts off. This has happened on several occasions at varying speeds. Speed varying between 30 MPH to 70 MPH. Engine will restart (be turned back on after wait time at the ignition) and drive following these incidents, however incidents reoccur. Also upon taking it to a GMC Chevrolet dealership for inspection, service department was unable to find any "codes" related to this. Fuel pressure was tested in stationary position and in driving and fuel pressure appeared fine. Dealership noted no issues. Upon picking the vehicle up after inspection the engine cut out again while driving on the way home, again without warning. Incidents occurred on dry roads. …
