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.

2003 Toyota Matrix Owner Comments

problem #2

My check engine light came on, and the local Toyota dealership charged me about $50 to tell me my catalytic converter needed replacement at a cost of over $1,000 for my 2003 Matrix with about 92,000 miles. Seemed unlikely, so I took it to a local non-Toyota repair shop, his computer also showed catalytic converter, but he said the way the car was performing, it might be the oxygen sensors. He replaced both, and the car has been great ever since. Too bad my local Toyota dealer wanted to gauge me.
