Please also check out the statistics and reliability analysis of the 2012 Mazda MAZDA3 based on all problems reported for the 2012 MAZDA3.
Gas leaking from back of fuel tank after filling it up. It I only fill up half way no leak.
Smell of fuel is very noticeable after filling up the gas tank. Further investigation indicates there is leaking somewhere near/around the tank but not on top where the fuel pump is. It is observed that the leak happens when tank is filled up full and more so if parked uphill. If filled up full, the leak seems to stop if car is parked downhill. Research indicates several other 2012 Mazda 3 owners have experienced the same issue. This is quite dangerous. For a part that is not moving or wearing out, whether the tank or attached hose, to break for a 7-8 year old car is unacceptable. This can cause a fire or explosion leading to death.
