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 Pontiac Aztek Owner Comments

problem #4

I have not driven my vehicle for 2 months because my mechanic told me my valve cover gaskets were leaking on to my exhaust manifold and that it why it was smoking when we stopped. I talked to my local GM dealer and they said it is not part of the recall so they could not help, so I have three choices let it sit in my driveway, pay several hundred dollars to get it fixed or drive it till it starts on fire. It has the 3800 motor like all the other cars in the recall. I can get a letter from my mechanic if needed.
