Failure to communicate with tcm/ecm/pcm. This problem has caused several occurances where driving the vehicle has been hazardous. Because of either the wiring or the tcm itself, I, the consumer, have nearly been in 2 accidents. At first I was told that it was the power steering assist module. Replaced that and problem still occurred. When the problem occurs, the gauges jump up and down and completely stop working (speedometer and tachometer), transmission shifts extremely hard when accelerating, power steering illuminates in the data information box which in turn causes loss of power steering (replaced power steering assist motor, issue still happens, 1 occurance of loosing power steering and being able to stop before going off the side a mountain when trying to maneuver a right hand turn), check engine light illuminates, when shifting from park to reverse, reverse to neutral, neutral to drive, the transmission engages very hard and results in an audible "clunk". 1 occurance of vehicle switching gears into neutral from drive, while driving (shift lever still in drive position),passlock light also illuminates in dash. Vehicle consistenly acts as it is going to stall (headlights and dash lights dim). Checked alternator and battery, both in optimal working condition. Presenting diagnostic code include p0700 and u0100. Vehicle maintanence has been performed at 3,000 mile intervals but has been pulled off the road due to the 2 occurances of near accidents. Vehicle has been experiencing issues for several months prior to removing it from opperation. I know for a fact, this Cobalt is not the only one having this issue.

The contact owns a 2006 Chevrolet Cobalt. The contact stated that the check engine and battery lights illuminated. The vehicle was taken to the dealer where the alternator was replaced twice. The contact also stated that the battery and relay were also replaced but the failure recurred. The dealer was unable to diagnose the failure. The failure mileage was 46,000 and the current mileage was 46,500. The VIN was unavailable.

My car shut off while driving out of a parking lot a couple of days ago. Everything shut down. I couldn't even brake. I was able to put the gear in park and restart it just fine. However this is the fourth time this has happened. The last time being on the george washington bridge. The very first time was 2 months after I purchased this car. I assumed it was because I went over a speed bump that was larger than normal. The second time I went over a pothole. The third time was on the highway. So I had a mechanic look at it and he stated that I could be the alternator. This was about 2-3yrs after purchase. However my time was very limited. I live in MD but I work in new york so I spend a lot of time there and leave my car at home. So I haven't had a chance to get it fixed. With this last incident I decided to search the internet and it turns out that I am not the only one with this issue. I found it funny that there were many others with the same or similar problem. I put in a search for "cobalt shutting off while driving" and found a couple of sites describing similar issues. This last incident reminded me of how dangerous this could be. I had my 4 yr old niece in the backseat and the exit of the parking lot was on a hill. Feeling the car rolling back and not being able to brake would surely be considered a safety issue. On a side note I did have my car examined for the recall I was given notice about. This was completed last year. Nothing abnormal was reported.

When I started my car and at the same time I wanted to pull down the window it didn't work. I think it was already too much for the car. It happened already 3 times in 2. 5 years and the car was new. Every time I have to go to the dealer to change the regulator in the window.

The contact owns a 2010 Chevrolet Cobalt. While driving at approximately 30-40 mph, the lights on the instrument panel illuminated and the vehicle suddenly stalled. The contact pushed the vehicle to the side of the road and had it towed to an authorized dealership. The dealer replaced the battery and the alternator. On another occasion, the antenna fell off while the contact was driving. The instrument panel also became warped and had a gap. The contact also stated that the cup holder broke off and she was afraid that her child would put her hand in the area which was on top of the shifter. The contact also stated the brakes sounded loud. The vehicle had not been repaired at the time of the complaint. The failure mileage was approximately 500. The current mileage was approximately 6,800.
