This is the second time that the vehicle has stalled at a stop. I am seriously concerned with the safety of my wife. What if this happens and she involved in a serious accident because her vehicle basically shuts off and leaves her very vulnerable" what if the vehicle stalls during driving" GMC is no help, I have called and all they say is there is no recall. I get on their website and it does not work. We have had trouble with the ignition, having to have it repaired and also the timing chain making horrible noise. The latest incident really concerns me as it may place my wife in serious danger. Please help!

The check engine light came on so I took it to radley Chevrolet in fredericksburg, va to have it checked out. I was informed that the catalytic converter was bad and needed to be replaced. The cost was $1125. The SUV is only 4 years old. The mileage is high because I tow it behind my motorhome. The real running miles should be somewhere in the low 60,000 miles range. The dealer told me that the SUV was out of warranty and that I would have to pay for the repairs. This is ridiculous that a 4 year car needs to have such an expensive part replaced and especially one that involves the emissions of the car. I believe it should be covered.

While traveling down the highway, check engine light came on and display read power steering problem. After getting off the highway and coming to a stop at a redlight, the car would not drive when the light turned green. It had no power, even though it was running and engine was idling hard and making a terrible noise. Car was towed to dealer and the fixed the cam actuator. Car drove fine for another 2,000 miles and same issued occurred. It is currently being repaired...again. Will file another complaint when I know what the issue is.

Camshaft position sensor error occurred. GMC has issued a recall for model year 2011 Terrains, but not 2010. Same issue is affecting that model year as well. (voluntary recall 11195 & 11195A).

While driving on the freeway in houston an engine power reduced light came on and my vehicle lurched and reduced in speed from approximately 60 mph to 10mph causing cars behind me to take evasive action and almost causing a multiple car major accident. I frantically kept trying to start the car and was able to get over to the feeder road. Since this incident I have done some research and have found numerous complaints for this issue and am surprised that there has not been a recall issued. This is a very serious and dangerous issue and I am surprised that more hasn't been done.

On Thursday July 22 when I went to go start my car my vehicle would not drive forward, it would only roll forward. The car dash stated it was because of the "stabilitrack" and the transmission light was also on. The car was towed and supposedly fixed. On Thursday July 30, I was driving on a major highway at 70mph about to turn off onto a ramp where my car stops driving in heavy traffic. The car was able to roll into the emergency lane. Again, the transmission light came on and "stabilitrack" came up on the dashboard. The car has been there for 4 working days and they still have not fixed it. They think it is a bad switch or wire in the transmission. This concerns me because it may happen again. If I did not recognize what was going on and thought quickly, I could have cause a major accident because of the speed the cars were driving on the interstate.
