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.

problem #2

Matrix 4-cyl

  • 30,000 miles


Parking brake doesn't hold vehicle on slope. Mechanic has fixed twice, but problem re-occurs in about two years. This is a safety issue since this is also the emergency brake and there is no warning when brake will start slipping again after repairs.

There was no drag when driving with the parking brake fully applied. The consumer was afraid the parking will not work in an emergency. Mr scc
