Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The Cobalt was introduced to replace two of Chevy’s smaller cars, the Cavalier and Prizm. But the compact’s fresh start that Chevy was hoping for was riddled with issues, most notably widespread power steering failure.

The power steering failed so often that GM was forced to issue a recall in March, 2010. Great, but what about other problems like the key getting stuck in the ignition or all the other electrical demons this car possesses?

And, oh yes — then there’s the terribly dangerous issue where the Cobalt randomly shuts off while driving. As it turns out, that problem is related to GM’s massive 2014 recall for a dangerous ignition switch defect. A recall that eventually ballooned to 2.6 million vehicles in one of the automotive industry’s biggest scandals.

Cobalt 4-cyl

  • Automatic transmission
  • 37,000 miles


I have a 2005 Cobalt I purchased new. I have had numerous problems with the brakes, headlights, a.C., signal lights etc. But the newest problem is the power steering it goes out without any warning. It does this every day at no certain time. And this is very dangerous as it is very hard to steer when this happens.when the steering goes out it says power steering on dash, most of the time I can pull over and turn the car off wait a minute and restart the engine and it steers fine for awhile. The car has 37,500 miles on it and the warranty just ran out. This could easily cause a loss of control and or a collision. Feel free to contact me with any questions you may have.....thanks.

#1 I brought it back because steering wheel always was to the left even though I was going straight. Dealer said it was fine, I complained to customer service and then dealer said they fixed it. When going straight the steering still looks left. #2 air conditioning not working, #3 liquid coming out of vents #4 cricket noises out of passenger side dash area. I was told air conditioning was fine, no cricket noises and it was normal for fluid to come out of vents. I brought the car back again said A/C is not fine I asked them if it could be some sort of filter (I am no mechanic) but it was. They had car all day, went to pick it up but they said dash was apart because they were fixing the problem with the fluid coming out of the dash (and I said I was told there was no problem) they had the car for the weekend. They tried to charge me for the filter and I said I would not pay for it because there was problems with that ac and defroster etc since day one. They took out the filter and put in an old dirty filter that did not come from my vehicle as the guy from the Chevy dealership in malden said he found it in the trash, (has made my daughter sick). #5 while driving the car I was getting off of the highway into a rest area and the car just died, there was no power steering no brakes etc. The key was in the switch and it was not off. I started the car up again. #6 the electrical didnt work, they fixed that. I have contacted Chevy customer service on several occasions and they say they will check into it etc and call me back, but they never do. I want them to fix the steering wheel, fix the car stalling out for no reason (we could have been killed) and put in a new filter not someone elses dirty filter. I don't trust the malden dealership. I have brought the car to the dealership on at least 7 occasions most of which they say nothing wrong.

My Cobalt has been in repair the center at 2 different dealerships for a total of 17 visits. The air conditioner leaks excessively into the passenger floorboard. My headlight indicator comes on repeatedly, my temperature controls do not always work, my emergency brake light comes when the brake is not on, most recently my gauges have been quitting as I am driving and my left blinker has stopped working. My car has been in a shop for a total of over 60 days since I bought it in Sept. 2005. I have contacted GM/Chevrolet in an attempt to settle these problems and they will not assist me. My warranty will expire in less than 8000 miles. GM/Chevrolet - manufacturer and dealerships- will not assist me. I am very unsatisfied with my purchase, GM delivered a defective car and they will not stand by their reputation.

: the contact stated while the air conditioner was on, there was excessive condensation on the dashboard. The dealership inspected the vehicle and determined the vehicle was manufactured that way. The manufacturer was contacted.

2005 Chevrolet Cobalt developed problems with the brake light equipment. Two days after the vehicle was purchased brake light illuminated on the dash. The consuemr contacted the dealer but they explained that there was not a problem. The vehicle has been taken back and forth to rectify the problem. The dealer has had the vehicle since April 23, 2005. The A/C would not work due to a short in the A/C pressure sensor.
