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.

2008 Toyota Matrix Owner Comments

Matrix 8-cyl

  • 46,000 miles


I noticed a chirping noise from the engine. My husband took the Matrix to a Toyota dealer who advised us, upon inspection that the bolt that holds the lifter arm hadsheared off inside the engine. We are extremely fortunate that this did not result in an injury accident whilst traveling at highway speeds! the service manager said he had only seen this happen before when a belt was replaced. The issue has not been resolved since the dealer and Toyota seem to feel that it is not their problem. The dealer quoted $2200+ and advised that if they cannot drill the bolt out, that the short block would need to be replaced.
