Plague with fuel system problem. 1st time check engine came on, when car reached 44,000 miles. I took it to dealer, they ran a diagnostic, and replaced the O2 sensor. Warranty covered. 2nd time check engine came on at 51,000 miles. Dealer replaced 2 of the fuel injectors. When car reach 85,000 miles, engine started sputtering when I pressed gas pedal, engine just dies on the street. This time dealer said fuel pump might be bad. So we got it replaced for $800. When car reach 100,000 miles I had fuel line cleaned from fuel tank to the fuel injectors, and replaced spark plugs. At 105,000 miles check engine light came on again. I took car to autozone parts and had it read. The code says, P2004 (variable tumble shutter valve stuck open). The next day I was going take it to a local auto repair shop and have it looked at, but on my way the check engine light wasn't lit anymore, so I drove straight to work. 3 days after, check engine light came on again, so I just ignored it. And 2 days later, it disappeared. All these time, since I bought my car I never missed a regular maintenance, I.e., oil change, air filter change, flushed fluids. The car has gone through tire replacement, new brakes pads, new battery. Right now, the check engine light is not lit.

My wife sondra was stopped in our 2005 Mazda3 when she was struck from behind by an individual driving a 2001 Malibu. The vehicle was doing approx. 30 mph when it stuck our car. Our car was then pushed into the vehicle stopped in front of her. My wife was injured and transported to the hospital, injuries were, 8 stitches to the bridge of the nose, back and neck injuries, she is under going therapy and is waiting for more test to be performed. The reason that I am contacting you is because of some of the concerns I have about the following safety that failed. 1. the drivers seatback broke during impact. 2. the airbag did not deploy when she struck the vehicle in the front of her. 3. the emergency switch that shuts down the fuel system did not activate. Our vehicle was totalled from all the damage, the car is valued at $ $18,700. I emailed Mazda approx. 10 days ago about my concerns and still have not received a response.

2005 Mazda 3S would not start. Mechanic reprogrammed the main relay and replaced fuel pump & gauge twice but problem persists. The fuel pump and gauge were replaced a second time but the vehicle still failed to start occasionally. The vehicle was taken back to the dealer but they were unable to find the cause of the problem. Mazda tech support was called and the they suggested changing the fuel canister. It was replaced on June 22, 2006.
