Door locks have failed on 3 out of 4 of the doors. Sometimes in the locked position, sometimes in the unlocked position. Some postings on this topic are referencing issues with wiring harness. If the locks were to not unlock in an car accident, or god forbid rolling over down a hill that there is the potential for loss of life. There are multiple complaints regarding this on the internet. GM is well aware of these failures. I really believe this should fall into the recall catagory of vehicles.

First owner of a 2009 GMC Yukon has had 3 door lock failures, which not only qualifies under the lemon law, but also poses a major safety issue. The first door lock failed. GMC does not consider door locks as a warranty item or safety item so I was forced to pay for a replacement. The next week, another door lock failed. The dealer did not charge for the replacement. Now, a third door lock failed only 10 days after the last repair. Why is this a safety concern? my child was able to open the door while all doors were locked. Due to E failure, the door was unlocked unknowingly. My child and any child or person risks falling out of a moving vehicle. Secondly, should a car accident occur, unlocked doors could result in a door opening and ejecting the passenger leading to death. There is a flood of complaints on the web for this issue. GMC has not owned up to it, but due to the major safety issues, this should be investigated and faulty actuators and the known pattern failure in wiring harness causing the failures should be addressed as an immediate recall.

Purchased a used 2008 GMC Yukon Jan. 23, 2010 and approximately 4 months later the first issue occurred with the car not starting in my driveway. I thought it was user error. A few months later coming out of the grocery store went to enter my vehicle and no start, went under the hood and moved the battery cable and it started. Later that night I tried to tighten the battery cable, but it wasn't loose. Approximately 1 month later while driving, the dash flickered and "stability traction" light illuminated with slight loss of power. Got to destination exited vehicle and upon return vehicle would not start until I once again moved battery cable around. The last incident which occurred on August 30, 2010 while driving approx. 15 mph through a residential neighborhood, engine just cut off. Wrestled car to side, put in park and restarted. This was the scariest incident because someone could have rear ended me. I took vehicle to shop GMC dealer and they found nothing wrong. 23,000 miles on vehicle now. Purchased with 17,500.

Some doors don't lock or unlock, I have had this into the dealership once to get it fixed. And now it has happened again, and thank goodness for car seats because my 3 year old daughter opened her door while I was turning a corner and almost his another car beside me. I am taking my Yukon in to get fixed again. The dealership said it was something to do with the electrical in the doors.

On all 4 occasions, the 2008 Yukon hybrid, lunges forward at low speeds, looses brakes, power steering and all power. Every time it has to be towed to the dealer. This has happened 4 times since August 2008. The first time there was a fire in the fuse box, then while the dealer had the vehicle, it caught on fire again. The dealer keeps telling me that it is fixed and safe to drive. The Yukon is back at the dealer and I am not taking it back. This vehicle is very dangerous and the government needs to look into this right away. I now have an attorney and we are contacting GM as well.

I have had multiple problems with my 2008 GMC Yukon. It first started with my radio cutting on and off. I have been to the dealer 3 times and they can't reproduce the problem. I have had the warning light come on alerting me that I have an open hood, unloosen fuel cap, and the engine light has come on and remained on for several days. Lately the alarm has been going off 5 times to date. I have notified the dealer but I don't feel that it is getting me anywhere. I have delivered it to them three times and have had them check it out twice. Today was the third time and they told me they didn't have a loaner car and to return on wed. 8.27.08. They did not write up that I was there today. I don't know what to expect the next time a dummy light goes off I only hope that it isn't something serious since all the issues seem to be a "boy crying wolf".
