I was driving and when I went over a small hill the car seemed to lose power. The service /ESC message came on. I was barely able to get to the side of the road the car was running but would not move at all. It had no power whatsoever. When I called onstar they said to shut it off for a minute and turn it back on to see if the code would clear. It didn't so I called a tow truck to tow it to banks Chevrolet (nh). After sitting in the car for about an hour with the engine running (it was February and very cold out) the tow operator arrived. I shut the car off for about 3 minutes, he then started it and low and behold the message was gone the car had power and he proceeded to drive it on the tow truck. The garage had the car for several days trying to recreate the problem. They could not. They said a service bulletin did go out about this problem. I will admit it does make me nervous the car was 1 month in my possession when this happened not even 1500 miles on it. I now have 7500 miles and no problems since then. It could have been catastrophic if I had been merging onto the highway and lost power at a high speed-thank-god that didn't happen!!! but really no resolution they couldn't find out what caused it they did however give me some song and dance about things loosening up from going over bumpy roads. Well I live in the northeast so that is pretty unavoidable.

I have a 2011 Malibu, I changed my tires out on my car and tire pressure low light came on, then 3 days later service ESC light came on, an I instantly felt like I was in a wrong gear, power and speed reduced, thankfully I wasn't in heavy traffic, I'm under the 5 year warranty can I get service, and is it dangerous for me to drive.
