I have the same stalling problem. It's happened 4 times...most recently at night in the rain on a 2-lane highway. The car suddenly stalls. I try to start it in neutral but the starter does not engage (headlights go off and everything else that's supposed to happen when you start happens...except no starter). Once off the road and stopped I put in in park...still won't start. If I turn it off and back on it starts and most times there are no problems. Once it ran rough and the most recent time it shifted rough.
 
Also...at times when I start it the windshield wipers turn on by themselves and run for a while before stopping. I can move the wiper switch but nothing happens.
 
Been to the dealer 3 times for all of these. Of course, it's never duplicated so they send me away.
 
Other than that it's a great car....much better than the Cavalier it replaced. Looks nicer, more power, better gas mileage.

What year is your Cobalt? How many miles does it have on it? Tell me if you call and what response you get from GM. It is so frustrating, maybe if enough call (thats a big IF) GM will take notice.

hi, i have 06 cobalt, stalling issues completely shuts off and I am getting the run around with my dealer. This will be the 4th time back to dealer since July. No trouble reports came back either. My cd died and had to be replaced. Also had problems with daytime running lights. I live in Pa and can't persue lemon law cause I have 21,000 miles. I am so aggravated that the dealer can't pinpoint the problem. It started with the fuel gage not reading full. I took it in for the head restraint seat recall and am so sorry I asked the dealer to fix the gas gauge. It hasn't been running right since. I have to keep 1/2 tank gas or more otherwise I am taking my life in my hands driving the interstate on a daily basis.
 
The dealer is now ordering a whole new gas tank unit including fuel pump? So another trip back in a week or two. I owe too much money to trade it in on another car. Thanks

I dont know if this is the right place, but im pretty sure this is electrical. First off, a few weeks ago, my car wouldn't start when i got up in the morning.. so i had to call roadside assistance, get them to get me and take me to the closest dealership, which is an hour away.. ok (oh, i have a 2006 cobalt). So i get ther,e i sit for 5 1/2 hours, missing school and work. ok, they said i needed a new battery, so they charged up my old one, told me to come back the next day. everything ran fine, im like ok.. well, two sundays ago, my check engine light comes on, after i am heading to edmonton (most of you probably dont know where that is, but its about 800km from me). so im going there, and all of a sudden my car becomes gutless and the check engine light flashes at me like 4 times.. whatever, i called the dealership they said to keep driving cause ther eis probably nothing wrong, cause the car ran good afterwards.. it didnt happen to me agian. ok, so two sundays ago, my check engine light comes on, and hasn't turned off since.. well, whatever, dealership told me to ignore it unless there was something phyiscally wrong with the car.. ok, fine. So i organize a check up on the car, just in case. (Jan 4th) So im driving around tonite, christmas eve, being bored.. and all of a sudden, my POWER STEERING sign turns on in my dashboard, and my spedometer quits, and everything is reset.. my trip counter, and everything, it just displays dashes.. well, this is getting quite annoying, because i seem to just have problem after problem ith this car... has this happened to anyone else??? anything like this!?!?!?! Thanks!

It will be almost 2 yrs (in Jan) that I bought my 06. I just took it for the 5th time to the dealer for the stalling of engine. I had problems with daytime running lights, CD player died, 4 times engine stalling with no lights turning on. Sensors were changed and the last visit I had (supposedly the gas tank and fuel pump replaced)
I don't know what to believe anymore. The dealer is very nonchalant about it and my salesman claimed the did nothing wrong & my response they did nothing RIGHT! Also asked if I wanted to trade car in and I said I should get a 2008 with no loss on my end and they didn't like that either. Heard again that they never get complaints and I'm the only one so I showed them the Edmunds complaints, no comment. I did contact 800# at GM and if there is a next time, I was told to open a case with Better Business Bureau. I do believe I have electrical problems also.
I even chose the bare bones package with no electrical windows etc so I would have less problems! Guess that didn't work. I also made the mistake of chosing a dealer with inconvenient hours never thinking I would be there so much!
 
Contact GM and BBB to start a paper trail. In PA, the lemon law is 1 yr/12 months so I don't qualify, I have 21K and am concerned about our winter coming up in the next 3 months. I hope they get it right this time.
 
I love the dealerships responses, like I have nothing better to do & make this stuff up about my car, barely missing 4 accidents with this car stalling.

Gas Gauge by gerald41

For anyone with fuel gauge problems there is a TSB out on it. I had it repaired in my car an 06 Cobalt. The fuel sensor is defective and has to be changed. I would fill my car to the cap and 15 miles later it would read a half a tank. I had no confidence in it till I had it repaired. I was told by a tech that the 05 and 06's had many issues that the 07 and 08's had most problems remedied. I had the radio changed because they found a short in it and the Keys stuck in the ignition as well.

2005 base COBALT electrical and keys by raydes

I have experienced fractures in keys followed by broken keys. The car also randomly displays ''LOCK'' on the radio but the action of turning off the car and starting it again makes the condition vanish without any code entry or anything else. The 2005 COBALT recently stranded me when the one good key I had broke off in the ignition. The dealer laughs and says he cannot fix what is not broken as the radio issue will not replicate in front of him. The key problem is explained by the dealer as " the only time this ever happened in the history of all COBALTS and therefore I must somehow be at fault''. GM/ CHEVROLET apologizes heavily and frequently '' that I am not satisfied" but follows with a nice two step of bewilderment and a promise to call the dealer. I was told today that the dealer told GM that he was too busy to talk to the GM representative yet but a conversation was promised. I could be stuck with a non running, broken ignition key car in a blizzard but GM is not able to arrive at a point of communication with a dealer they have a legal agreement with. The problems with building small cars persist at GM and it is interesting that the competition taking market share from them in various U.S. product segments today was founded on building mostly notable small cars.
