2014 Mazda MAZDA3: gas smell in the cabin

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.

Noticed strong smell of gasoline when the car was parked. Took it to an independent service dealer who diagnosed leaking fuel from top of the tank. Gas tank was removed and replaced. Tank cost was $380.00 plus repair shop labor/supplies cost. See attached invoice. During a recent online search for this vehicles current book value I noticed there was a manufactures recall issued for this same problem, that I paid to have repaired. I never received any recall notice for a leaking gas tank problem for my vehicle.

I thought I smelled gasoline when sitting in my car. I got out and inspected all around the vehicle, discovering that gasoline was leaking underneath. Both the hazardous fumes and the potential for a fire in the vehicle put me at risk. The loss of fuel on public roads could have resulted in danger to anyone behind me on the road due to the fire hazard and potential loss of traction before I noticed the problem. I immediately brought the car to my mechanic's personal shop (he is also a master mechanic at a local automotive dealership). He confirmed that the leak was gasoline and diagnosed the problem as a rusted seam near the top of the fuel tank having ruptured, allowing the leak and filling the cabin of the vehicle with fumes. I knew that the local Mazda dealership would be unable to repair this promptly, if at all, since they had just fixed the exact same problem in my mother in law's vehicle of the same make, model, and year, and had struggled to get the replacement tank for weeks due to the supply chain problems experienced during the COVID-19 pandemic. Therefore, I paid my own mechanic to source and install a tank, and coat it with anti-corrosion treatment. I contacted Mazda, explained the problem, and demanded they reimburse me, as the car was only 8 years old at the time. The Mazda representative refused to do anything to help me and did not answer my subsequent emails, so I posted about this problem on the [XXX] forum, and discovered others have had the same problem as my mother in law and I. There were no warning signs of the problem other than the smell of gasoline. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

The car has a smell of fuel when filling the tank and for a long period following. My mechanic tells me the surface of the tank has decayed and that it will cost $1600 to correct. I don't have the $1600, so he told me to fill the tank only halfway, which seems to have solved the issue of the fuel smell. I can't understand how a fuel tank could decay and believe Mazda should be responsible for something that is poorly designed or improperly manufactured.

- After filling up the gas tank and putting the cap back on, there is a distinct smell of gasoline until some of the fuel is used up. In summary, it appears to be spilling or leaking fuel/fumes when we fill up the tank. -This is a problem when parking our car in our garage and we are concerned that it could cause a fire. - We have not yet confirmed this with a dealer or independent service center nor have we had any other entity or person confirm this. - This issue was noticed recently and within the last year or so and without any alerts and/or warning lamps. - We understand that there is a recall on the Mazda3 for model years 2014-2016 regarding the ICV Valve (deformed gas tank) and even though it appears to be the same issue, our vehicle doesn't fall within the recall group. - Please help us determine if this is the same problem as the 2014-2016 model year recalls and if your agency will need to issue a similar recall on this model year.

Had a gas smell in our garage for months, thought our riding mower or snowblower was the cause but realized it was this car. Took to our mechanic and they said it was the fuel leak issue from the federal safety agency campaign 16V684000 however this car was manufactured in Dec 2013 and the official recall campaign began with cars manufactured the following month aka Jan 2014. We have been unable to get assistance from the dealership or reach anyone at Mazda due to the huge hold times.
