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.

2001 Pontiac Aztek Owner Comments

problem #1

Oct 192005

Aztek 6-cyl

  • Automatic transmission
  • 50,000 miles


The contact owns a 2001 Pontiac aztec. Five months ago the exterior and interior lights malfunctioned while driving. The contact replaced two oxygen sensors; one in May 2005, and one in August 2005. The contact was still experiencing the same problem. The contact went back to auto zone today and their computer showed her that she needed another oxygen sensor. The car was no longer under warranty. The contact has not spoken to the manufacturer. The contact stated she had gone to several mechanics, and they did not know what the problem was. The only thing showing up was a bad oxygen sensor.
