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.

2004 Chevrolet Aveo Owner Comments

First off: Chevy knows that they used a bad oil gasket as it is made out of a very cheap material that warps with age allowing oil to leak out. This occurs in 2004-2007 aveos. They have not and will not recall it, nor is it under any sort of warranty (seeing the age of the car). I had so many places look at my car and spent hundreds of dollars getting every "leaky valve" and "leaky gasket" replaced until I finally figured out where it was really coming from and got a quote from multiple sources for 900 smackaroons. At the age of my car and the amount of oil being lost and my wallet not being large, I'm not going to fix this problem.
