Vehicle wouldn't start. Like the battery was dead, wouldn't even try to turn over. Go to turn the key off and pop my trunk where the battery is located and I can not get my key to turn all the way back to the off position, as a result I cannot remove my key. The speedometer read 30mph even though the vehicle never started and wasn't moving. Non of the electronics were working so I was unable to pop my trunk. This has happened several times before and eventually the vehicle will start and when it does the battery light stays on and the dash reads; engine performance low. The transmission will surge as I am driving and I cannot go faster than 30mph. I have even had the car shut off completly while I was driving down the road. After anywhere between a few hours to a few weeks the vehicle will stop acting up and drive normal for a while. …

About once a month "power steering" appears on display, sometime power assist is gone, most times it is still there but transmission shifts very hard and stalls engine when stopped for red light. If power steering comes on right away after starting vehicle, shut off, smack pass side of center console, then start, usually off then, but if vehicle is hot from sitting in sun, or very cold in winter, you have to drive it and either heat it up or cool it off before pulling over parking and shut off for 15 minutes, then hit it then start it. Told dealer of this before p/s recall work was done they said it was not related, when I went to pick it up they ask if we were having trouble with the power steering and transmission, I said yes, they said oh have a nice day.

The first time it happened, was at interstate speeds.(60 to 70mph) the second, was in city stop and go traffic. The third was backing out of my driveway after a 5 minute idle. The fourth was when my last mechanic was test driving it because he thought he'd fixed it. Dash lights blink on and off, all warning lights come on, engine cooling fans stop operating, transmission hunts for what gear it should be in; resulting in the transmission self destructing. Engine management, other than the cooling fans, seems to be unaffected. I've replaced 4 TCM's so far; as all mechanics say that is the problem. It works for a few days or a week, then the same problem manifest. This seems to be a problem with quite a few GM vehicles.

I purchased a Chevy Cobalt brand new in 2005. From the moment it left dealership I have had one recall issue after another. The main issue is stalling while driving caused by the ignition switch. This had been fixed at schumacer Chevrolet several times. My vehicle continues to stall and I am terrified of causing an accident due to this recall which GM refuses to fix. I feel I was sold a lemon and all I get from GM and the local dealers is nothing. My vehicle is worse with the stalling. I don't know where to turn to. Please help. I don't want monetary compensation from GM if I or any passenger in my vehicle dies in an accident due to a malfunction due to GM.

My car has been stalling out as it gets to lower speeds and shifting very hard. There is a clicking in the dash somewhere and the speed odometer was fluctuating. It hesitates and tries to shut off at every stop. Loosing power and speed even down hill. The power steering reading has been coming on. And the display for gas mileage will now go to all lines no numbers. I am starting to be afraid to drive my car. That its going to get me rear ended when I am turning and it shuts off. I fear for my safety and the safety of my children. I went so far as to this morning recording the dash as it was acting up so I can show my husband.
