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. Notes: The Toyota Matrix is the mechanical twin of the Pontiac Vibe.

Both models were a joint GM-Toyota venture, manufactured together at a NUMMI production facility in Fremont, CA. Only the heating & A/C systems are different.

Matrix 1.8L

I have a 2003 Toyota Matrix first owner, we performed all schedule maintenance on time using all specified fluids and OEM replacement parts. at 130K miles the check engine light came on with the code P0420, Catalytic converter system fault. I make some search and the parts only the price is around $1,400.00. in my life I have had over 20 vehicles never had to replace the catalytic converter, I always trusted Toyota but I am very disappointed this time.
