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.

2003 Pontiac Aztek Owner Comments

2003 Pontiac Aztek. Took in due to fluid leaking into oil and causing it to look like a "milky" substance. Told that these vehicles are known for this issue and that the problem was with the intake manifold gasket. Had that replaced (over $1,000) - then discovered still a leak - now they are saying it probably needs an engine. The vehicle is not even 10yrs old. I read another description similar to this. How many individuals have to be gouged before something can be done about this. If this is a known problem with these vehicles, seems like something needs to be done to stop the manufacturer from preying on their customers.

I bought a used 2003 Pontiac aztec 6 months ago, and found out recently that there is a lot of known problems with the orange anti-freeze eating away at the tubes and gaskets of the engine. We are currently having to pay over $700 to fix this known problem. I think someone needs to investigate this issue and a recall needs to be done.
