general problems of the 2011 Chevrolet Tahoe

Just purchased truck it has not been 30 days and the service suspension system light came on and when I drive the car will accelerate faster on its own. Which was very scary with kids in the car now my engine light is on plus traction control and it sometimes won't go over 70 mph. I feel like I was told truck was in great condition but it's not and scared it might accelerate on its on with kids in car. I was on highway when this happened I work from home so I haven't really had chance to drive truck but I feel un safe driving it berger Chevrolet should be shamed I have called multiple managers with no call back.

Driving on highway at night. Go to high beams and motor immediately begins to rev up/down, and run erratic. Switch beams to normal position=it stops. When depressing key fob to open and close doors, it only works frequently. Bizarre electrical issue. . . .

Stabilitrak and abs light comes on while driving, the door locks go crazy, radio goes in and out and you lose the ability to accelerate. Engine acts like it wants to die out. The first time I had it taken in, they said it was a sensor so I paid $600 to have it fixed. 6 months later it started doing the same thing so the same sensor was replaced again. One month later my Tahoe is doing the exact same thing and now the dealership says it's a short. I don't think they know what's going on and they are just trying different things to see if it works, so now I am out of pocket over $1000 for them to keep guessing what going on.

I was driving on the highway with my child, when then engine light came on. Seconds later the "stabilitrak off and traction control off" came on. "service traction" came on and within seconds the power steering left and the brakes seemed as if they were not working properly. Thank god there was not a lot of traffic!! I got over as the engine sputtered and finally died. This could have been a tragedy!! I have read many are having this problem and it needs to be fixed before someone really gets hurt!!.

I started to encounter the following errors on my 2011 chevy Tahoe; service traction control, service stabilitrak, engine power reduced during the winter months of 2012-2013. I could be simply doing the task of warming the vehicle up in the morning, driving on a paved road going 35mph, or full blown in the middle of freeway/highway traffic. The vehicle will violently start to idle with the warning indicators mentioned above, I then have to somehow pull over in the middle of traffic because I'm unable to get any power due to the engine power reduction. Shut the vehicle completely off and patiently wait until it decides to reset. This could happen once a day to multiple times a day. It could happen immediately one after another or at any given time. The service engine indicator will stay on for about a day before it goes away. Leaving you with the impression the vehicle is fine. Well it¿s not until it happens again and again. I was about to take my vehicle in right before it was turning spring weather was warming, (not sure if this had anything to do with the issue) but surprisingly it stopped. All spring and summer I had not one issue until now! January 8th 2014 and the weather is cold. This seems after reading on a few blogs on the web, numerous gm owners are having the same issue. They take the vehicle in to have serviced and the service fails. It sounds more like a faulty product which is unsafe having the engine power reduced with no ability to get out of traffic in the middle of the freeway.
