My 2014 Mazda3 is leaking from a seam in the fuel tank. There is an existing campaign for other 2014 Mazda3s #16v684000 but my VIN apparently is not caught in that campaign. Seems highly suspect that some vehicles of the same year were missed when developing the campaign. My vehicle is on the lift now and my mechanic is watching fuel drip from the seam in the tank. Note this is happening with a full tank of fuel, when vehicle is stationary. After parking there is distinct fuel order emanating from the rear of the vehicle.
Purchased as new vehicle. From the time of purchase I smelled gasoline in garage after parking overnight. After 1,000 miles/3 months the gas smell became increasingly stronger and gas mileage plummeted from 30 mpg to 18 mpg. Took the car to the dealer for repair. They said the seams of fuel tank were leaking--entire tank had to be replaced; not safe to drive.
