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.

Takata recall, I was driving my vehicle 2 weeks after 2 recalls were repaired on it. It was rush hour I went to push on my breaks and the steering wheel locked and the car turned off, at this point im freaking out. I contact Chevy service for assistance and they advise that they can not fix the problem because the recall was repaired they also could not duplicate the problem because it was to dangerous for their employees. So I ask the bank to refinance me another vehicle because this car was way too dangerous to put my baby in, they said no due to my credit. I then had them repo the vehicle because I would not continue to pay for a death trap. Now they are suing me for the remanding balance on the vehicle. I am going to court and wondering if I have a case.

I have recently had my Cobalt to the Chevy dealership in redlands ca due to a horrible gas smell. The dealership looked if my car was under recall for the fuel pump however it was not. I indeed had a crack on the fuel pump having to replace it as the fuel smell was over the top. I paid for the part and labor out of pocket yet wonder why my VIN was not recalled when I have a 2009 Chevy Cobalt with the exact same fuel pump issue"?"

Driving on a highway going 65 mph and the check engine light came on along with the traction light. The display says engine power reduced, service traction. I was nearly rear ended when this happen because my car automatically slowed down to 10 mph and stalled out and was barely able to get it over to the shoulder. I keep going to different mechanics and everyone says its something else and I have already sank over $1500 into this and yet it is still happening with no end in sight!!

I have a 2009 Chevy Cobalt and since I purchased it it has been problem after problem first the key got stuck in the ignition before the recall. I had to spend all day at the dealership, then I had to take it back for the ignition switch recall. Next it was taken back for suspension problems and a cracked steering column, now I kept hearing a noise when I pressed the gas to speed up took it to two places and it was the catalytic converter which cost me $1,548 out of pocket because the warranty I had didn't cover the catalytic converter this car only has 89414 miles on it I keep up the maintenance but this car is beginning to make me not want to buy any american car ever. I initially purchased the car because it was economy car, good on gas which is still good on gas. I seen in the earlier models there were recalls on the catalytic converter so I was trying to find out if there were any on this particular model? when I purchased this car I was happy about the the car but problem after problem is beginning to be more than I can handle and the last thing is this catalytic converter, thank god I had the money. The catalytic converter was cracked and gaskets had to be replaced.

Service engine light has been on intermittently for a year. Dealer said it was probably due to a loose gas cap and nothing more. Engine started shaking when stopped at stop lights and the service traction and traction off lights would come on. The engine light would start blinking, and if the car was stopped for too long the engine would shut off. One mechanic said it was the cam shaft, which I got fixed and still continued to have the same problem. Took it to another mechanic who replaced the cylinders. Problem continues to occur which engine shutting off if stopped longer than a minute.

I have already had the recall service performed on my 2009 Chevrolet Cobalt, but the ignition switch problem still persists after having the recall service performed. There's the possibility that a safety hazard to the american public still exists if there are cases similar to mine. The vehicle ignition was inadvertently switched to the "off" position while I was getting onto a highway. I was shifting my hips to adjust my seating position, and my knee bumped into my keychain and caused the ignition to switch to the "off" position. I lost speed control and power steering, but I was luckily able to move to the shoulder of the highway, shift into "park", and re-start the vehicle. This event happened within 48 hours of me having the recall service performed at a Chevrolet dealership.

My wife tried to start the car on 4/30/14. Put the key in the ignition and try to turn the key to start the car the key wouldn't turn. It was locked up. The steering wheel wouldn't turn, the engine wouldn't run. Eventually if she comes back after approx. One hour and try again the key will turn in the ignition and the car will start. This happens couple of time a year since we bought the car brand new from the dealer. We contacted the dealer service department; they told us that they do not know of any such problem with this Chevy model.

Driving vehicle on highway when engine check light comes on and "reduced engine power" message appears on status bar of dashboard. Repaired at dealership by replacing throttle control body. Occurred twice more over next 3 days, repaired at different dealership saying first throttle control body was defective. Occurred again 2 days later, dealership replaced crankshaft position sensor. Occurred again 1 day later. Need to take in for more service. Basic internet research shows that this is common problem on Chevrolet Cobalts.
