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.

My 2004 Chevy Aveo has had more problems than you can imagine. I had to replace the timing belt twice, severe engine damage both times. Ocean Chevrolet and GM were absolutely no help. Rotors had to be replaced at 48,000 miles, an evap leak for another $600. Both timing belt repairs were over $2000 each. I have put more into repairing this car than I paid for it. Got runarounds from the dealer and GM and wouldn't recommend a Chevy product to anyone.

I purchased my 04 Chevy Aveo on June 20,06. Five days later the brakes were metal to metal. My car was not safety inspected before the sale. Since then I have taken the car back to where I purchased it several times and have even had the service manager to ride with me to show him that the brakes are sticking. (the calipers need to be replaced) tim marburger Chrysler/Dodge tried to say that is was a warped rotor due to excessive mountain driving, my car was only driven 7 miles one way to go camping and 7 miles back once a week. I would hardly call this excessive. The first tank of gas I got the mileage of 284 miles since 06/20/06 until now 10/10/06 my gas mileage for a tank of gas is now 210 miles. Nobody at the dealership has offered to fix my car. I have been cussed, talked to like a dog. The general manager denny fruith slammed my car door and proceeded to argue with me in the front parking lot in front of the showroom doors. Refused to fix my car and it was still under warranty, the dealership put my lug nuts on so tight that they could not be manually taken off. The vice president of the company Mr. Felix mcclat refused to fix my brakes and also refused to even let me come to the dealership and have them loosen my lug nuts. And the car was still under warranty. The brakes on my car will put themselves on without me pressing the pedals. And when you do press the pedals you can be going down hill and take your foot off the pedal and the brakes grab and the car will come to almost a complete stop...down hill. All this was shown to the service manager david anderson and the car has not been fixed yet.
