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

The Toyota made master cylinder had already been replaced in this car once when the brakes started slipping again. Basically any time I needed to stop short or stop quickly I can feel the brakes slip - sometimes it's bad enough that the car shudders. It's dangerous. I took it to a different and reputable shop (we had moved, hence the different shop) and they said the master cylinder was bad again and replaced it.

I have had the Toyota made master cylinder replaced in this car twice already. I know it's the same problem because the brakes are slipping when I try to stop quickly again. Toyota says they can't help me because the part is just over a year old - even though this is the third cylinder to go bad on this car.

It's dangerous, and I'm furious. I bought this car in the hopes that I wouldn't have to buy another car for a very long time, and now forget it. I will never buy another Toyota again. Ever. And the customer service representative told me "I'm sorry you feel that way ma'am" and hung up on me.

I bought this car used from an elderly gentleman who was the original owner. I took it for a test drive and when I tried to brake going down a hill my foot went straight to the floor. The owner had the master cylinder, brake pads, and rotors replaced by a reputable auto shop and then I bought it from him. He paid five hundred for the repairs (the Toyota dealership quoted him a price of 900). This is my first rant about this problem. The master cylinder has since gone out twice more on this car.
