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.

Cavalier LS

First my catalytic converter went, and rather than look at why, it was fixed. then it ran out of oil 300 kms later, they thought they had forgot to put in oil, even though i had seen black smoke spewing from the tail pipe. finally it ran dry on a road trip and killed the engine and it had to be replaced. also many problems with the suspension, steering - over $11,000 CDN warranty work on a car that cost $16000 - definitely a lemon. GM and my dealer have been very good, but now that it's almost completely off power train warranty i am very afraid. new clunks all the time.
