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.

CarComplaints.com 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.

Toyota accident I drive a leased 2009 Toyota Matrix. At 8:24 am on November 16, 2009. Pulling into a parking space at the doctors office building boca raton. The car was almost stopped and my foot was on the brake, when the car revved up to the maximum, jumped the curb and hit a palm tree. I immediately switched off the engine. I was dazed, and after a couple of minutes I got out the car to see the damage. Having heard of car mat problems, I inspected the mats, but nothing was out of place. After a few minutes, I went to my doctors appointment, but had to leave before I saw the doctor, as I didn't feel well. Despite a lot of front end damage, the car was drivable, so I decided to drive the car to my home, but I was frightened all the way as I thought the car might do the same thing again in traffic. When I got home I called allstate and reported the accident. I told them there is a problem with the car, as it accelerated by itself, and the driver side airbag did not inflate.. per instructions from allstate, the car has been towed to ed morse Cadillac for repair of the damage incurred. My question is, can I legally break my lease and return the car to Toyota, as it is unsafe.. updated 05/25/10 updated 07/29/10 updated 12/21/10.
