I noticed an approximate 4'' crack on my dash between the windshield and steering wheel hump. I then noticed a similar crack emerging near the top left portion of the front passenger side air bag. I thought maybe the employees where I get my car wash were applying too much pressure. However, after looking online to buy a new dash, I found that I was among many GMC owners that have the same issue. I dont think it is a coincidence that we all have the same cracks, in the same location on the dash. Also, the chrome plating on both my driver and front passenger inner door handles is peeling off. I heard that exposure to the sun may be a cause, however, my two front windows have had 5% tint on them since I bought it. Also, I just got my vehicle back from the dealership because of check engine light issues. The problem is fixed for now, however, after researching online it seems like there are hundreds of GMC Yukon owners experience very similar issues with their vehicle's engine. I keep reading about the "reduced engine power" and "service stabilitrak" warnings.

Vehicle gets extremely low gas, 13 mpg on average. Burns oil. Need to add 2-3 quarts of oil between oil changes. Engine cooling fan stays on for extended periods while driving. All of which the dealership says is normal for the truck. They removed the driveshaft because of clunking at 25K mi. Reaction carrier replaced and transmission reconditioned at 36,663 mi after car stopped in the middle of the street. Car had to be towed in. At 62K miles engine light on and idles rough. Replaced throttle body. At 67K won't engage in reverse and makes clunking sound from reverse to drive. Replaced reverse housing, reaction shell, etc. At 75K had a reaction carrier failure, lost power brakes and lost power to the car. Almost was rear ended. Had to stop in middle of parking lot during christmas rush. Waited 5 min and restarted. Engine light stayed on, but was able to get to dealership. Was told that throttle body needs to be cleaned every 15K miles under service maintenance. This was the first time I heard this! not really sure why it had to be cleaned, though, just had the throttle body replaced 13K miles ago. It seems that there are major flaws in the design of the engine. Obviously, the dealership has been putting band aids on my problem because they don't know how to fix. I have been very lucky that my family and children have not been in a major accident due to the major flaws in the engine designs. Every time I get my car fixed, the tech assures me that they have fixed the problem. I am really afraid to drive this car with so many close calls. The car is a hazard to drive!

I was driving the vehicle down the road doing 65 mph. The engine light came on and the message appeared that stated "engine power reduced" "service stablitrak" "traction control off". the car lost all power and I was unable to go over 20 mph the rest of my trip home. I went from 65 mph to 20 mph in seconds, on the interstate full of traffic. When I got home I then noticed a "hot" smell. I then had the car towed to a mechanic.

"reduced engine power" message while driving on the highway at 65mph. My truck immediately dropped down to 35 mph and nearly caused a wreck.

Serious safety issue please read, research and address!!! 2007 GMC Yukon 4X4 my stabilitrack light comes on then engine power flashes and I loose power ongoing problem! I was doing 70 mph down the freeway when this happened fortunely no one was behind me serious safety issue! I have had it to the dealer X2 two months ago. At first they cleaned the throttle body but could not pin point the problem. The second time I had it there they again could not find the problem. I have researched this online and this is a common problem. No real conclusive answer to why. There needs to be an investigation as this is a serious safety issue!! I am taking my vehicle to another auto mechanic. My vehicle has about 140,000 miles however this proble began nearly a year ago but it did not reduce engine power. The problem fixes it self if you shut the truck off and restart. Please address!! [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The cooling fan is very loud and stays on for an abnormal amount of time when the car is in park or at a stop while on only when the temperature outside is over 85 degrees. The fan will continue to stay on while driving for 10 to 15 minutes. Sometimes it won't shut off until the car is shut off and then restarted. Had it for repair on several different occasions at GMC and the technician said that is was normal.
