Car would randomly shut off driving in the middle of the road. Super dangerous and unsafe. Never gave a code about this. Never warned. Would just stall out and die. I was unsure of what the issue is. Though luckily I saw a youtube video (thank god for DIY mechanics and kind people) and fixed it myself. The job isnt hard to do at all in the Cobalt at least.

Just one thing to note is that the throttle body on this POS is electric or something but the motor is super sensitive if you want to remove and clean it you have to be careful not to move the motor manually. Otherwise this cheap POS will think it's always actuated when it's installed in the car and cause a more costly repair. Make sure you mechanic knows that too if you take it to him/her. It would probably be better to do it yourself as not everyone knows of these caveats.

I might've nudge mine a little bit because after I reinstalled it i had check engine light on for a while but it cleared on it's own. I could hear a louder revving on acceleration tho ever since (though I never cleaned it since 2008 to 2017 so that could've been the original sound). Though to be fair the car never randomly shut off on me again in the middle of driving or turning

My 06 Chevy Cobalt SS keeps shutting off on me while I'm driving. I took it to a local GM dealer when the problem first started and they couldn't find anything wrong with it! My husband thought I was nuts! Well, until it happened when he was in the car with me. When it happens its always when I'm slowing down (usually under 20mph) and it just shuts off. The radio still plays though. So I have to put it into park and try to start it and in order to keep it running I have to rev the engine while starting it so it keeps running. Today it did the same thing to me but it was a little different. When I try to start it, it clicks and won't turn over at all. I am planning to take it to the shop tomorrow and they better fix it and not send me away saying there isn't anything wrong with it. They need to pull their heads out of their asses and listen to their customers. We aren't made of money and we aren't bringing it in for sh*ts and giggles. There is something clearly wrong and its their job to fix it! I hate this car and I cant wait to finish getting it paid off so I can get rid of it. DO NOT BUY A CHEVY COBALT!!!!!!!! You will be biting yourself in the ass in the long run...trust me!!

I have a 2006 cobalt ls that i bought brand new and for the past year the engine has been shutting off completely for apparently no reason and with no warning. It kills backing out of my drive way, stopping at a stop sign, trying to cross an intersection I could go on for days. It always starts right back up. Just the other day it killed in the middle of a busy highway as I was trying to cross and someone almost hit me. I have a 7 month old daughter that I dread taking anywhere in my car cause I never know when this is going to happen. Its being brought in this week. This isn't even the only problem I've had with this POS. Had I known this car was going to be this much trouble I NEVER wold have bought it! Because of this car I WILL NEVER buy another Chevy!!!!!!

My 2006 Chevy Cobalt stalls randomly. Especially if the heater or air conditioner are running. The rpm's drop drastically making the lights flicker. I have talked to the mechanic about it and taken it into be diagnosed 5 times in the last year and a half. No one can find anything wrong with it. The dealer never hooked it up for a diagnostic test. I found out later because the engine control model doesn't work. He didn't tell me that of course. The last time I took it in, there were two other recalls on it that needed to be done and I wanted the problem fixed once and for all. He had me leave it for over two hours. I came back and he had not done the recalls and said his guess was the stalling problem was coming from inside the motor. He would have to tear it apart to get to it. He gave me an estimate of 1400.00 based on a hunch. He told me he would do the recalls and the repair at the same time and to make an appointment when I could leave it the whole day. I told him it might take me a while to come up with that much money. I asked if the car was safe to drive in the meantime. He assured me yes. My car had over 140000 miles on it by then. He didn't tell me the recalls were only covered up to 150000 miles. He never told me the engine control module doesn't work or that there was a "special coverage" on it (if it was done before 150000 miles). I took it to a competitor owned Chevy dealer to see if I would get the same kind of diagnostic and estimate and that's when I found out about the special coverage. Of course it was too late now as the car sat at 150100 miles. He said he promised to find the problem though, no matter what it took! He talked way too fast and pitched too many service memberships and extra upsells at me for me to trust him, but he talked me into doing an oil change. (I figured it needed it anyway) He said during the $40 oil change he'd be able to tell a lot better what the problem was instead of having to charge me $125 diagnostic fee. His quick switch in tactics made me spin on my heels and leave. After I left I realized he what making it seem kind of him "saving" me from an expensive diagnostic test, when in actuality he knew the diagnostics test wouldn't work and knew I didn't know at the time that the test was connected to the ECM coverage. They all know the ECMs don't work because none of them run diagnostic reports. They don't tell you they don't work or that they are covered for replacement. They don't know what's wrong with it without that report, so they guess at the problem with the most expensive prices they can think of and keep doing different repairs after that to rake in the revenue. Meanwhile cars with children in them are losing all power at high speeds on the freeway. Lives are at risk and yet they keep up the sherade. It is clear to me that if they know all these things and are not telling anyone and are not informing owners of the coverage that will let them know what is really wrong...they must be under orders from GM themselves. I'm guessing they made the car with faulty parts and systems that they knew could cause massive life loss, but put them out anyway because they were in the middle of a bankruptcy. So our cars are bursting into flames from the gas leaks, driving head on into traffic from loss of power steering and multiple car pile-ups from loss of power on freeways. There are also owner reports on this model of the seat belts not restraining you in an accident, the doors not unlocking and the air bags not deploying. I feel like I'm being led on a long walk down a short plank. I am on a mission to get a class action law suit filed on GM and hopefully the service managers too since they are all in on it. My experience with them constitutes fraud, theft, coverups, lies, reckless endangerment, gross negligence, and attempted vehicular manslaughter. I am outraged. Please everyone join me in this fight. It is not ok that our lives mean less than theirs and they continue to get away with this. This is intentional criminal activity. It stopped being just an issue about lemon cars and has become an obvious case of criminal intent.

I own a 2006 Cobalt LT Coupe. When the car had around 60,000 miles on it I began noticing that the car would idle very low when I would come to a stop or when I would start moving from a stop. It would idle between 300-700 RPM's and often the engine would stall. This happened several times at major intersections or when I would pull out of a side street and could easily have caused an accident if I had not pulled off the road quickly. I did some research online and was told to have the throttle body and fuel injectors cleaned out. I had this work done last week and the car is running like new again. I have had no more problems with a low idle or stalling. Also the dealership wanted to charge and arm and a leg, but I had the work done at Goodyear Auto Center for only $110. Hope this information helps anyone with the same problem. Thanks.

I just got my 2006 chevy cobalt and it had 50000 miles on it. And when i got my recall letter in the mail, i took it in and ever since, its had nothing but problems. first the clutch master cylinder went out. Then the slave cylinder went out. And now I'm at a stop light and go to take off and the engine stalls and go to start it back up again and it wont start. So luckily i was right next to a Circle K and so i pushed it in there. I jiggled the wires on the battery thinking it was not on securely. So i go to start it up and it works. So I start driving back home and it just starts bogging down and loss of gas pedal and there's nothing. So my dad pulls me back home and were looking at it and go to start it up and will not start. It cranks and everything but it just wont turn over. I don't know what it could be. I'm lost. Has this happened to anyone while driving

This is the fourth time in 3 months that my car as jerked violently and acted as though it will stall when I'm driving so bad that I've been forced to pull over and shut my car off.

So far each occurrence has been when I was going below 45 mph, but I do a lot of highway driving for work and am concerned it will happen then too. Once it happened as I was reversing out of my parking spot upon initial start-up of the day, once about 2 minutes into my trip while I was still in my apartment parking lot, once when I was about 5 minutes into my trip(today's) and once when I was on my way home from work about 10 minutes into my trip.

If I shut my car off for a minute and restart it seems to not happen again for a few weeks. A ding (similar to the one that sounds if the door is ajar or the passenger doesn't have their seat belt clicked yet) will sound before it happens so I have a bit of a warning. The ding has sounded in the past and nothing has happened but now each time it goes off my car does this.No service lights are on and I do not get a message on my screen that says why it is sounding or what is happening.

I hope I don't kill myself or someone else if this happens on the highway.

Update from Sep 12, 2011: After talking to a mechanic friend this complaint should have been listed under cylinder misfires..

This car is a death trap. It goes dead in the middle of the road. It goes dead when you come to a stop. I was taken my children to school and my car died in the middle of the road and we were almost hit. This car need to be recalled because this is not the only problem i have with this car. First the radio stops working then the power steering went out, the front end started to shake, Rattling noise from under the hood, orders of gas, gauges don't work properly, uses a lot of gas, I had to replace the battery, Sometimes it want start. The Air works half the time. CHEVY COBALTS ARE DANGEROUS

My car goes off whenever the rpm get below a certain point and I dont know why. I was told to have the gas filter replaced and that would fix it and that has not helped. It still happens 5-10 times a day a lot of times in heavy traffic. I think there should be a class action suit or a lemon law looked into on this since so many are having the same trouble. Has anyone came up with a solution. I've looked at older complaints and this seems to be a real problem with this car and no real solutions. Some of the complaints go back to 2007!Anyone please respond what you did hopefully it wont cost a arm and leg.

Sunday thunderstorm...bad lightening. Afterwards, went out to go home from work, car won't start. My son and my mechanic came, could not start car. Towed to shop, horrible time for now fourweeks not fixed. FINALLY..some computer part[s] fixed...needed programing?? new keys?? and now still have not gotten car back. THIS IS IMPOSSIBLE...WHO WHAT WHERE DO I GET SOME HELP WITH THIS?? MY POINT is that my mechanic was unable to figure this out and GM had no help/knowledge of what/why...is this a lemon...or is it something that should NEVER happen?? I only have this car because it is what I can manage $$..and how much is this costing me [besides no transportation for 4 weeks, loss of income etc]. IF I wasn't still paying [family loan] on this, I would dump it...
