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.

problem #3

Prizm 1.8L

  • Automatic transmission
  • 125,000 miles


This problem was due to excessive oil burn which ate up the catalytic converter and exhaust. The post o2 sensor in the cat failed first and that was $110 to just get that and you had to take out the pass seat to replace it which was a pain in the ass. Even though it is supposed to be stainless steel it was a bad circumstance. I feel like I was sold a piece of crap and lied too.
