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.

2000 Oldsmobile Alero Owner Comments

problem #4

Jun 012007

Alero 3.2L V6

  • Automatic transmission
  • 113,000 miles


This light was on all the time and every time I had it checked the codes were the same, o2 sensor and purge valve. Every year I would have to pay for them to be replaced and the light would be off for about 5 to 10 min. then come back on. After several mechanics I finally got someone to look into it further. There is a connector between the fuel tank up to the engine that comes loose or even not connected. Unfortunately you have to be under it to look and thats not so easy. Happy hunting!!!

Autozone told us that the car has a 4th cylinder misfire after running tests on it. the misfire causes the car to shake pretty bad in reverse and don't get as good of gas mileage.
