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.

Vehicle will shut off without warning as I am driving and when I try to turn it back on the engine seems to struggle to turn on. I have no check engine light on dash board.

While driving my 2010 Chevrolet Cobalt home after leaving work, I was entering onto the thruway when my check engine light activated, my dashboard reader said, "engine power reduced", the car then lost acceleration, started to buck and shake. I quickly pulled to the side of the road and let the car sit for 15 minutes. Upon start up, I put the car into drive, it bucked into gear and I proceeded with caution not doing more than 30-35 mph. I went to advanced auto parts and ran their free obdii diagnostic reader. The code that came back was PO641 - engine control module - port #3. the check engine light cleared out after 2 days. The car runs fine now. Very concerned though.

Power steering gave out on a U-turn. Shut off the engine and it worked again. Looked it up on line and found out there was a recall. I brought it to rotolo Chevrolet in fontana, ca (the place where I bought it). They told me that there was a recall and they replaced my motor already. They charged me $100 and told me that they could put an upgraded motor in for another $200. The car was not repaired. You can buy the motor on line for $80. It's under the dash, two bolts and a plug to pull out. It takes ten minutes and a 12 mil wrench.
