Power door locks are defective. My Cobalt locks go up and down by themselves the switches or fob will work. By doing some research online hundreds of people seem to have this problem. It is defective and General Motors should issue a recall about this.

My taillight assembly is 1/3 filled with water, due to a broken seal (which is allowing water to enter). Due to the broken seal, the water damaged the entire L/R taillight assembly, rear turn signal (drivers rear), the lamps, bulbs, flasher, and switch. Several mechanics said that the broken seal in my 2009 Chevy Cobalt, appears to be a Chevrolet manufacturer's defect.

Cobalt 4-cyl

I started my vehicle up and parked it in the garage. When I went to remove my key from the ignition, the key wouldn't turn and I couldn't get my key out. In order to turn the car off, I had to remove the fuse and unhook the battery. I'm taking the car to schmidt Chevrolet in centralia, il first thing tomorrow, but there is no active recall on my vehicle at this time. I see that his has been an issue for multiple Cobalt owners and even the mechanics that I was able to get a hold of told me that this is a known issue. I believe that my vehicle should be included in this recall and that any money spent should be refunded to me by Chevrolet for a poorly designed ignition.

The contact owns a 2009 Chevrolet Cobalt lt. The contact stated that the vehicle failed to start after being informed by neighbors that the headlights and brake lights were illuminated all night. The vehicle was towed to a dealer where they advised the contact that the computer module failed and needed to be replaced. The vehicle was repaired for the computer several months later. In addition, while driving approximately 50 mph, the power steering failed. The vehicle was taken to the dealer and repaired under NHTSA campaign id number 10V073000 (steering:electric power assist system) however, the failure recurred shortly after having the recall repairs performed. The manufacturer was contacted and they offered no assistance. The failure mileage was approximately 100.

Headlights side marker cover came off on both headlamps not at the same time short time after the first one then the right side came off causes glare. Power locks do not function any more with buttons only function with gear shifter sometimes locks will go lock to unlock by themselves multiple times with or with not driving the car. Contacted GM and they informed me that the headlights are not recalled on my year but they are for the 2005's. obviously they did not fix the problem from then. I will not by another GM product ever.

Ignition switch stuck on. Had to disconnect battery and stall car. Found recall # 10256 and called dealer, dealer said they have no recall notice. Dangerous situation for someone that does not know how to disable car.

Cobalt 4-cyl

  • 54,000 miles
Key is stuck in ignition in the on position. Car will not turn off. Had to disconnect the battery (while car is running) to turn off. Although support bulletin 10256 references this exact problem with 2009 Cobalts, GM and dealer are saying that my car is not included in this and I have to pay to get fixed. The support bulletin says dealers fix at no cost through January of 2013. But...my VIN was not included in the support bulletin. This is a serious issue. My daughter was not home when this happened. Having to disconnect the battery while the car is running and damage that may be caused to other equipment because of connecting and disconnecting the battery. I see so many reports of this problem online with some people having issue. How do we get the list of VIN's updated. How do we get the word out to customers that this is a known problem. I am very upset that I have to pay for this. I was told that a key getting stuck in the ignition is a common problem. GM did compromise with me with my deductible but I honestly think this should have been a recall and I should not have to pay for a known issue.

Ignition switch. Could not turn off engine. Could take key out in any gear but wouldn't turn off engine. Had to pull fuse out to get it off. For 79,732 miles I think this is a hazard.

The key will not turn in the ignition cylinder. Therefore the car will not turn off. There is a special bulletin #10256 about this exact problem including only the 2009 Cobalt however as there is not an open recall the manufacturer will not repair my car because my car has a branded title and they will only repair 'open recall' items. This issue is not listed in the global database when my VIN is searched but it needs to be listed under my VIN and there needs to be an open recall on this issue because it is certainly a huge safety problem that many owners have been experiencing. The only way to turn the car off is to get under the hood and remove the fuel relay fuse. In case of a fire this would be a catastrophic safety issue which could result in serious injury or even death.

During July I had to have my 2009 Chevy Cobalt towed into a repair shop because I couldn't turn my key in the ignition. I had to have the ignition cylinder replaced which cost me over $200. Now in November 2011, 4 months later, my car is having the same problems. There hasn't been a recall yet on this and multiple people are having the same issues. This is getting ridiculous.

Key is stuck in the lock cylinder. Can not turn off car. This is an extreme safety hazard. Electro-mechanical release mechanism interlocked with gear shifter appears to be working correctly (inside bottom of steering column). The key is physically stuck in the ignition lock cylinder, so the car can not be turned off. Quick search on the web reveals dozens of the same complaint on Cobalt models at least back to 2005.

Cobalt 4-cyl

  • 40,000 miles
The first occurrence was on 9/9/2011 at 7:30 am in the morning. The vehicle would not start. The second occurrence was on 9/9/10 at 5:00 P.M. the vehicle started and when arriving at designated location the vehicle would not stop in park. The engine continued to run, unable to take key out of ignition, the vehicle when put into other gears was able to drive. We attempted to get the engine to stop and get the key out of the ignition but we failed to do so for a lengthy period of time. The battery had to be disconnected with the engine running. This decision was made after no other alternatives could be made to shut off the vehicle. This was a dangerous situation and could have cause electrical burns or other issues while doing this.

Issue: My ignition key will not turn once inside the ignition, preventing my car from starting. Dealership: Will charge for replacing and cylinder, housing and key if vehicle exceeds bumper-to-bumper warranty (36,000 miles or ~2 years, whichever comes first). Cost including labor is $797 + tax! number of occurrences: 2 safety: Depending on where you last park your car, you can be stranded anywhere! tip: I have learned from the tow company that this is the most frequent problem from these Chevy vehicles and that many people have had this problem.

I have a big issue about the odometer reading on my Cobalt. I have made several complaints to the dealership. I bought my car 7/29/09 and it now has 59,740 miles on it. This is only an in town car. I bought tires in 3/11 and the tire place last week said I put over 12,000 miles since then. This is no way possible. They say they have tested it and there is no problems. I have not change my driving habits since I bought this car. The car I had before this had a regular odometer and not the digital. The car was 1997 and it had 155,000 and I drove out of town a lot. By the end of the year I won't have a power train warranty anymore. There is just no way in hell this is correct and I have heard others say the same. Someone needs to step up to this issue.. this looks like a way for the manufactures to get out of warranties.
