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.

2002 Chevrolet Monte Carlo Owner Comments

problem #1

May 202006

Monte Carlo 6-cyl

  • Automatic transmission
  • 40,000 miles


I purchased the vehicle new in June of 2002. The car currently has 120,000 miles on it's 3.8 V6 engine. Every 40,000 miles we have had to put a new catalytic converter on the car. The check engine light comes on and the code reads catalytic converter bad. The dealership has made the repair under warranty each time, but can not identify the reason for the converter going bad. I have heard this is a common enough problem that GM extended the warranty on the converters for 10 years or 120,000 miles. The car runs well and gets good mileage. The check engine light never comes on, except when the converter has gone bad. I have tried E-mailing GM, but get no response from them. What are my rights here?
