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.

The gas tank leaked gas due to corrosion on the top of the tank at the fuel pump. Strong smell of gas fumes evident and puddling of gas under the car after being driven. The problems was diagnosed at McGrath City Mazda in Chicago and also by my local garage JDH Auto repair in Prairie du Sac, WI. The fuel tank was replaced, along with the evaporation cannister. Until their was actual leaking of gasoline, there were no signs, lights, warnings of this problem. I have retailed the old tank if you wish to inspect the tank. This car was washed on a regular basis and did not show other issues from corrosion.

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.

July 2018 I noticed the rear passenger wheel getting really hot and making a popping sound after driving it on hot pavement. The brake caliper was stuck and I had to get a new rotor, rear driver's brake caliper and new brake pads. I had to wait 3 weeks for the caliper to come in. The mechanic said it was odd all the other calipers were available for immediate delivery except the rear passenger one. We looked online and noticed a recall but my VIN was not included. Fast forward 1 year - august 2019, I was smelling fuel around the driver's wheel well and inside the vehicle after fill up. I didn't notice any fuel leaking onto the ground underneath the car. I took the car to my mechanic and there is a fuel leak coming from the seem of the gas tank. The whole tank has to be replaced and possibly the fuel pump. Once again I have another wait for the parts from mazda - at least a week. These are 2 very expensive repairs in the matter of a little over a year for a car with 30,000 miles on it. He said when he looked under the back seat he couldn't believe how much fuel leaked out. He said from looking online, my car should have been recalled for both of these incidents since other models of the same year were. I contacted mazda corporate about each of these issues and they tell me my vehicle was not impacted by the recall and there is nothing they can do since it's no longer under warranty.
