“My 2006 Toyota matrix completely stopped running while I was driving it to work to virginia from maryland on feb. 18, 2010. I was unable to restart it and had to have it towed to my mechanic. Later that day, my mechanic called to inform me that it was a computer problem with the engine control module because he had not been able to start it again after he brought inside the service bay. He informed me that there was a technical service bulletin regarding the engine control- engine no start condition and that Toyota is responsible for the repair since it is still under warranty. …”
NHTSA complaint #10314639, filed 2010-02, 35,913 miles“Heat shield hanger assembly failed and now heat shield vibrates against exhaust pipe making terrible noise. This is a very common problem as researched on the net. Toyota needs to fix this free.”
NHTSA complaint #10470254, filed 2012-08, 55,000 miles“Intermittently my 2006 Toyota matrix xr suddenly slows down to about 20 miles per hour and would not respond to pressing gas pedal. When this happens I will have to pull up to the side and turn the engine off for couple of minutes and then start. Then it would be fine. It has happened on the highway and local roads. It could be dangerous if it happens right in the middle of highway. So far in the span of less than a year it has happened more than five times. We took the car to the dealer. They quoted p2103: throttle actuator control motor circuit high and will cost $1085 to fix it. …”
