The check engine light has been illuminated as well as the traction control light is on (indicates ABS needs to be serviced) also transmission "slips" when moving forward. At times when both the engine light and ABS light are on the engine will reduce power. Transmission was replaced at 63,000 for the same thing! have had to numerous shops who cannot locate issue. The doors will not lock shut- they come forward and pop out and reopen. Must operate manually.

It is probably a shorter list to list what we haven't had trouble with, but here goes. 1. the back power sliding doors will open and shut at will. Driving down the road, parted in the grocery store parking lot, etc. The neighborhood kids regularly come over to tell me my doors are open. My husband almost missed a flight because he spent to much time trying to fight with the door to stay shut. They have replaced almost every part of the doors several times, but was told by the dealership that last time I took it in they didn't know what to do now. 2. door locks will lock and unlock at will. One day it locked my 1 year old and 3 year old in the van when it was 107. It locked them in from the time it took me to walk from the passenger side to the driver's side. It finally unlocked on its own after not quite 10 min. My children would be dead if it hadn't already been cooled on the inside, but they wouldn't have lasted much longer. The dealership states that they can't duplicate the problem and don't know what to do to correct. 3. noise in steering column. Rack and pinion replaced, another repair done. The repairs last about 5 - 10K miles. 4. transmissions slips. They did a reset of something, but transmissions still slips, but the dealership states that the transmission is fine. 5. fuel gauge. It has always floated, was told that was how GM makes their gauges until I took it the last time to the dealership and now they state that it is a fuel sensor, but it is out of factory warranty and they never even looked at it before as they always told me that it was functioning as designed.

When doors are locked, either sliding door button on remote will unlock all doors and open sliding door with driver not knowing it leaving interior exposed to weather, thieves, animals and anything else nearby. GM refuses to correct it or even consider a buy back.
