2003 Mazda MAZDA6 Owner Comments

problem #3

May 152006

Beginning in 2006, my 2003 Mazda 6 would randomly experience power failure while driving. This was both scary and dangerous. I would be driving, the car would completely loose power with no warning and all the lights on the dashboard would come on. I would have to pull over, turn my car off and back on, and then it would work fine till it randomly happened again. Obviously loosing power at a high speed is extremely dangerous for both myself and the other drivers. I took it to the dealership many times and they were never able to determine a cause. I brought my car to the dealership over 10 times for this behavior. Finally in August 2008, I was reading on a Mazda message board that this behavior is caused by a bad throttle body. There was even a Mazda service bulletin issued for it in 2006 (bulletins 01-016/06 last issued May 18, 2006). I called the dealership, had the throttle body replaced and have not experienced this behavior since. The service bulletin had serial numbers of bad throttle bodies listed on it, mine was one of them. I believe that this should be a Mazda recall, not just a service bulletin, as dealerships do not even seem to be aware of the problem and it the car is extremely dangerous if the throttle body fails.
