Vsa Warning Light On problems of the 2011 Chevrolet Equinox

While driving the 2011 Equinox will jerk or jump as if being hit from behind while attempting to accelerate between 2nd and 3rd gear. The check engine light will not turn off. The stability track light comes on and off periodically while in motion. When the car is being turned off it shakes as if the motor is going to fall out. I have to turn off the ac before turning the ignition switch to off position to decrease some of the shaking, yet it does not prevent it. Furthermore while driving at approx. . 30-35mphs, the car jumps to 5th gear without allowing to accelerate any faster in the mist of traffic. The 2011 Chevrolet Equinox shakes and makes a wining noise while idling. It does so to the point where the hood is shaking. The car only has 54000 miles on it. Also I have to constantly adjust the seatbelt while driving because it cuts into my neck which is very uncomfortable and a huge distraction. This car will now go forward in drive but it will not reverse.

I was stopped at stoplight at 8pm the car shook as I started to turn left and the stability control light came on then low power engine light came on in my 2011 Equinox. The car powered down to 2 mph, it would not accelerate so I turned into a parking lot, shut the car off and turned it back on same thing happened again. I called onstar and had the car towed to phillips Chevrolet (great service) in frankfort, IL. The service manager called and told me that the throttle body had to be replaced. I had the extended warranty so the cost was $100. 00 to me, without the warranty it would have been $600. 00 to fix. I asked if he has replaced many throttle bodies in this model car he said quite a few. The car was fixed. I emailed Chevrolet and asked how many throttle bodies have been replaced in all cars, they said no recalls on this car. I was unsatisfied with their answer, that was not my question. Chevrolet called me back and said that a person would call me about my concern. They called and told me the same story, no recalls and the dealer could have been lying to me, which made me upset. I asked to speak with a supervisor and he told there were no records kept of how many throttle bodies have been replaced, which I do not believe. He also told me about a fuel pump problem that chevy would fix only if my car had a problem and a chain belt problem that could a cause serious problem to the engine if the car showed symptoms. I was not happy with that answer either. I will take my car in for a chain belt and fuel pump check now that I am aware of the potential problem. The supervisor told me that I would have to contact your agency about my concern. I would like an answer to my original question, how many throttle bodies have been replaced in Chevrolet cars? why did this happen and will a recall be issued? thank you.

I purchased a 2011 Equinox lt - Chevrolet -Dec 2010 - wanted a nice and safe car for the new year - I am a mother with small kids and wanted a smaller car than what I had, which was a Ford windstar, I had for 13 yrs. I started to have problems with the Equinox in July, August and again now, with the stability tract service light going on and lossing power and now this third time with no power to the trani - I could not change gears, I would give it gas and it just wouldn't move - then the car power locks go crazy -lock and unlock and the transmission jerks. I do not feel safe in this car. I hope they fix this problem and figure out what is wrong before someone or myself are in an accident.
