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.

2005 Toyota Matrix Owner Comments

Request to the government: Please look into suspension problems in the 2005 Toyota Matrix and similar Toyota that cause irregular and premature tire wear, including "cupping" which could lead to unexpected tire failure and which cause owners to be required to replace tires prematurely. I experienced this problem, first noticed by loud, unexpected tire noise. I had to replace 4 tires at 30,000 miles, far earlier than ever in my 50 years of driving experience. A dealer unofficially admitted there is a problem with Matrix suspension. The internet has many angry owners describing the problem (under T. Matrix tire problems, and similar). Toyota never admitted the problem was faulty design, but in light of recent events, this clear fault should also be investigated. This is a defect that may have contributed to dangerous events at worst and extra expense commonly. Thanks

05my Toyota Matrix - irregular wear of tires possibly due to front shocks. Brand new tires don't last more than a few years on these vehicles. There are numerous complaints on the internet yet Toyota has not issued a tsb for this issue. It's not that the tires have lots of tread wear, but they wear unusually and lead to vibration - even after they are maintained and balanced. Additionally, I recently replaced my 4 tires that had unusual and irregular wear. With this wear, the vehicle steering wheel shakes significantly above 50mph. Please look into this complaint for a possible safety recall. Front shocks should be covered up to 80K since most of the 05's are almost out of warranty. Again tread wear is still good, but it's the way that the tires wear that is the issue.

Premature wear/cupping of tires on my newly purchased 2005 Matrix. Per tire manufacturer, it's a mechanical defect, not a tire problem. So, far taken to dealer twice on the same issue. Both times was told it was the tires. I will be taking car in again now to have them check proper alignment. Awaiting response from evaluation at this point.
