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.

There multiple times were my vehicle will lose all power and not restart after being turned off. I have had the battery changed to brand new, plus a different alternator installed with no fix to the issue. I do believe my vehicle ECM has gone bad and I have not received a recall notice.

The contact owns a 2007 Toyota Matrix. While stopped at a traffic light, the vehicle engine seized without warning. The vehicle restarted and while driving less than 10 mph, the speedometer read 20 mph. The failure recurred multiple times. The contact mentioned that smoke started emitting from under the hood, as well as, the right passenger seat. The contact heard a loud abnormal noise. The contact stated that the engine sounded like it was going to start on its own and then the windshield wipers activated and the dashboard lights flashed. The firemen arrived and unplugged the battery. A report was filed by the fire department. The vehicle was towed to the contact's residence and then was taken to the dealer for investigation. The vehicle was not repaired. The approximate failure mileage was 85,000.

I am requesting that dot NHTSA investigate the electronic acceleration system and/or the ECM causing sudden unintended acceleration of my 2007 Toyota Matrix. On 9/18/2010 my son was driving my 2007 Toyota Matrix. He was pulling into a parking space in front of a store & was almost completely stopped when, even though he had his foot off the accelerator & on the brake, the car began to accelerate on it's own. He then pushed harder on the brake & turned the wheel & the vehicle continued to accelerate. The vehicle ended up crashing into the glass window of the store, to the right of the parking spot, coming to a stop with the front end inside the store. There was approximately 4 feet of sidewalk between the front of the parking space and the building and about a 2 inch raise in surface height. My wife later informed me that she had an unintended acceleration problem that same day while driving the same vehicle. She turned onto a street & was traveling at approximately 25 mph & approaching a slower moving vehicle in front of her. She then took her foot off the accelerator to coast. The vehicle continued to accelerate with her foot off the accelerator and without the accelerator pedal moving. It accelerated to about 50 mph when she then had to apply the brake & tap the accelerator several times to get the vehicle slowed to avoid hitting the vehicle ahead of her. I have contacted Toyota & they are sending an engineering analysis company to inspect the vehicle. I was contacted by the company on 9/27/2010 to find out where the vehicle is & set up the investigation. The Matrix is currently at the progressive collision center in clearwater fl. No work has been done to the vehicle, awaiting Toyota inspection. Could you please investigate this incident.

Sudden lose of power affecting steering and braking. When taken to the dealer I read the Toyota service bulletin issued in Sep 2007 that specifically stated that warranty repair only in the event a customer complains. Toyota has left many drivers of corollas and Matrix with defective computer which causes lose of power which includes loss of power steering and braking at high speeds. This is dangerous especially on a turn or with an elderly driver. This should have been a recall and proactively repaired.

The computer of my 2007 Toyota Matrix suddenly died while I was on the highway and I was forced to maneuver to the side of the road. I was lucky that I was able to pull over without an accident.

Check engine light would come on and tach would jump all over- diagnostic tool read bank one low pressure. Light would go off and on by itself. Shortly after while driving on the highway car almost stalled and would only go around 20mph then corrected itself. This became a daily event - took car into dealer for service this spring they had to replace ECM - car had 55000 or so miles on it. Car now has 64000 miles on it and it is starting to do the same thing.
