Engine light came on with evap leak code. Small leak at first then included large leak code later. Also began to notice strong gas smell outside vehicle after fueling. Turned out the fuel pump ring that holds down and seals fuel pump to fuel tank had cracked. Over time the split became larger. When tank was filled, raw fuel would leak out around pump on top of tank. Which also happens to be right under the rear seat where me kids sit. Replacement was expensive because the ring could not be removed from under the seat. It required dropping the tank to repair. Mechanic felt it was a stress crack. The fuel pump had never been worked on before. The original ring was installed at the factory.

Tl*the contact owns a 2004 mazda3. She stated that the vehicle could be driven as an automatic or a manual. While driving 20 MPH in manual mode she attempted to shift gears, to no avail. She had to take her foot off of the gas pedal in order for the gears to release and afterwards the gears started to shift on their own. She was able to exit the freeway when the vehicle lost all power, but continued to accelerate. She was unable to stop the vehicle or make a turn. The vehicle began moving from one lane to another and accelerated through a red light to avoid a collision. The vehicle stopped accelerating within in a few minutes. The vehicle was towed to a local mechanic who diagnosed the failure as the intake manifold. The intake manifold melted, damaged the sensor and the catalytic converter. The mechanic replaced the catalytic converter, sensors, and the gaskets; however, she had to add oil to the engine because the engine light illuminated constantly. She took the vehicle back to the mechanic who stated that the engine also needed to be replaced. She contacted the manufacturer and filed a report; however , the manufacturer stated that they would not assist with the repairs. The engine was not replaced. The failure mileage was 25,000 and the current mileage was 75,000.

While driving on a residential road, at a low speed, changing gears from 2nd to 3rd, the car stalled. Upon trying to restart the car, it wouldn't turn over. After the car was pushed off of the road, there was a puddle of oil left behind. Realizing that the car wasn't going to restart, it was towed to a local repair shop. After being put up on the lift, it was discovered that the rod slammed into the engine blocking, seizing the engine. There should have been no reason for the rod to crack on a well maintained engine, on a 2004 vehicle. In order to get this car back on the road, the engine will need to be completely replaced. I don't see any recalls on this make and model, and I truly feel that there was something compromised with the vehicle, in order for this to happen. The oil was changed just 5k miles before. There were no check engine lights on... We are very upset about this news and are hoping mazda has experienced other problems such as this one.

The lights on the console keeps popping on. First it was the air bag light that took 4 unsuccessful visits to the dealer. That problem subsided? And now the engine light is popping on...

My mazda3 is 4 months old and I have been towed 2 times in the last 3 days. Both times the check engine light went on first, then the engine started running rough and then I lost acceleration power and could only go a few miles an hour to pull over. The second time it happened was within 2 miles of the dealership after I had picked it up from "getting fixed"--the throttle body was replaced. Now they are telling me it was because I was "low on gas" (under 1/4 tank). Prior to this I was having hesitations at 30 miles an hour--most noticable when engine was cold. The dealer could never notice the problem despite my bringing it for service 2 times. ? If the problems are all related or not.
