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.

2004 Toyota Matrix Owner Comments

problem #3

Low noise from engine area, then heard a pop or thud. After this came a scratchy/grinding noise when car was in gear and coasting. The noise went away when clutch was depressed or car was taken out of gear to coast. I called a service repair to make an appointment the same day. The very next day the car locked up and was undriveable. Sounded like the engine had fallen out the bottom with horrible metal grinding noise. I had to have it towed ($150) and the service center said I would need a new transmission and clutch and that this is a common problem with Toyota Matrix and corolla. After reading online, it seems there is a problem with Toyota owners with low miles having bearing issues and that this problem has gone unaddressed. Even though I was going only 10 miles per hour, the car locks up. This issue will kill someone, someday. Cost of repair will be around $3,100+.

My car started making a weird noise. When the clutch was pushed in, the noise would stop. 3 weeks later I had to go to work so I got on the highway and the noise was getting louder and louder. My front wheels locked up and my transmission shot me out of gear. A car almost hit me which would of cost my life. I will never buy a Toyota again. It costs $2000 to fix. Hopefully you guys do something before someone gets seriously injured.
