2014 Mazda MAZDA3: check engine light

Filed Jun 14, 2026 · Fuel system · RI

The fuel tank leaks fuel at a full tank and smells of gas in the cabin until about 3/4 tank. Car was dripping a large puddle of gas inside of a parking garage. Problem has been reproduced by my mechanic even after replacing the fuel pump retaining ring. It has not been inspected by the manufacturer or police. CEL did not come on until recently reporting a very small EVAP leak. Inside the car and the surrounding area would smell of gasoline even if there was no leak in the ground.

Accelerating on the highway passing a semi-truck when I lost acceleration power. Nearly caused a serious accident at highway speeds. Engine light then came on. After the incident the car's engine would stutter when accelerated above 2000rpm. Was able to bring it to a local mechanic who diagnosed both fuel pumps as damaged and replaced. Part was not inspected by police or insurance as it did not lead to a crash.

While merging onto the highway and accelerating to highway speeds, the car lost power, the check engine light flashed, the traction light came on, and the check tire pressure came on all at the same time. The car also would not allow me to accelerate past 35-40 MPH. After taking it to the dealership, it was determined that one of the four engine coils needed to be replaced. A month and half later, the same thing happened and another engine coil is needing replacement.

Occasionally the engine will hesitate when accelerating, and then the check engine light, tpm, and stability control light will illuminate on the dash. Less frequently, the engine will occasionally stall while driving or while sitting at a stop light. The lights on the dashboard will remain illuminated, so I do not think it's a total loss of power.

On february 23, 2015, I purchased a new 2014 mazda 3 s grand touring sedan with technical package, VIN # [xxx]. The vehicle current mileage is 5,470. Since purchase, this car has had a stalling problem that is intermittent, unpredictable, and not reproducible on demand. Stalling means it does not respond to normal pressure on the accelerator, and literally coasts for a period of time. This time may vary from 2 to 10 seconds in a given instance. During this time the motor is running, there is no check engine light, and no codes are thrown. I have learned that quickly repeated pressing of the accelerator may help terminate the stalling. Common factors when stalling occurs seem to be when the engine is warm. The car has been driven for a while, and then the car has been parked for a short time, restarted, and moved back to traffic followed by a 90 degree right or left turn or car is driving normal route then stops for a stop light/stop sign or traffic, followed by a 90 degree right or left turn. In both these scenarios, there is a sharp turn. The car will just finish the turn and then stall when the accelerator pedal is pressed. It should go without saying that if this problem occurs at the wrong time, it could be a major safety hazard to life and property.
