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 have been two instances of this problem. The first time, I was completely stopped just back of an intersection, after coming out of my employer's parking lot, preparing to make a right turn on a two lane urban thoroughfare, when all of a sudden I felt the engine rev and my car surge forward, although my foot was on the brake. I pressed hard on the brake to no avail; I thought I was going to be propelled into the intersection into traffic. At the last moment, I managed to stop, I'm not sure now, if I applied the emergency brake or what, because although I relayed this incident to several people, including my brother-in-law, my aunt, and some coworkers, I later dismissed the incident as, other than what it was, possibly due to road conditions (a large building was being built alongside the road at the time). Today, however, while completely stopped waiting for the light to change in front of the exit from the lower parking lot this time, the same exact thing happened again: The engine suddlenly revved, and the car surged forward. I instinctively pressed on the brakes as hard as I could, but the car wouldn't stop until grabbed the gear shifter and put it in neutral.

2007 Toyota Matrix. Consumer states that vehicle stalled out while entering a highway. This issue almost caused her to be in an accident. She states that two days prior to the vehicle stalling out she was at the dealership getting maintenance work done and service of the engine due to it puttering. After 20 minutes of sitting, the consumer was able to restart the vehicle and drove it to the dealership. The consumer was charged an additional $1,197.28 after just having paid $ $606.94 for maintenance work. The consumer believed the stalling problem occurred because of something they dealer did when they first had the vehicle, or the problem was a part of a recall.

While driving the car on the night of December 6th it suddenly stopped. I waited for a while, and the car started again; after a mile or so it stopped again. The car stopped a total of 4 times before I was able to get home. The next day I took it to a mechanic who indicated that it had a "recall" problem. I took the car on the 7th to the Toyota dealership. On the 8th they confirmed that indeed was a "recall" problem and that they would probably will need to keep the car for two weeks, because they did not have the parts at hand to fix it. I had to rent and borrow a car in order to move around. Toyota should have had the parts readily available and not keep the consumer suffer for their total lack of preparation. I did not get any correspondence from Toyota in regards to this specific recall.

2007 Matrix bought new, having stalling and puttering engine problems when it had only 67,000 miles on it and regular maintenance. Early April, 2010, car stalled out when I was entering on-ramp to freeway 15 in California. A car almost hit me in the rear as a result. Managed to get car over to shoulder, where it died. Couldn't restart it for 20 minutes. Got it to Toyota dealership where I purchased it. Explained the weird stalling problem. They charged me $1,197.23 and only two days earlier had charged me $606.94 for a total of $1,804.22. I told them I thought it was something they had done; or part of the recall or a related safety issue of Toyota, but dealership wouldn't listen. Argued with me, poor customer service. I am now writing to Toyota to request reimbursement, as I've seen articles (cnn time article dated 8/10/10, saying there have been thousands of complaints on 2007 matrixes for stalling problems. Toyota wouldn't even acknowledge this, and made me pay this outrageous amount.

I was driving home from work when I noticed the door light was on the display console in my car. I was at a red light and checked to see if my door was open, it wasn't, the door light remained on. I continued driving, but smelled plastic burning. I looked down, saw orange flickers and realized my car was on fire. The fire was burning in the drivers side dash, it was contained behind a small storage compartment. I tried desperately to put the fire out, threw water and left over soda on it, but I think I actually made it worse. I screeched into a gas station, put the fire out, and called 911. The fire department came out and said I did everything right. I am now having difficulty getting my car into a body shop. The insurance company I am with has yet to tow the vehicle and now I find it is costing me out of pocket expenses, due to my insurance not rolling over to cover a rental. I am extremely frustrated. I did call Toyota, who said I could tow my car in, but the car is "no longer under warranty" per the service guy. I would like advice as to what to do. I am waiting for my insurance company to tow the car to a local bodyshop, but am extremely wary of having a car that has been on fire repaired.

I was driving down a very busy 45mph highway when I suddenly lost the ability to accelerate in my 2007 Toyota Matrix. The rpms dropped to approximately 1000. I had to coast in to a parking lot where my vehicle was then towed to a Toyota dealer and the engine computer was replaced.
