- 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. …

Gas tank is leaking from the TOP. I could smell gas after a refill (and refilling a portable tank) that I thought must have been a spill I hadn't noticed, and the smell faded. But then it happened again at the next refill, and I knew it wasn't just a spill. Brought it to our trusted mechanic who said that the TOP of the tank was rusted out (wow!)(so, not from road salt) and needs to be replaced. Not cheap, but worse, I'd been driving around in a very hazardous situation that Mazda knows happens. No warning lights, no recall. Thanks, guys. Here's a thread about this being a common issue: https://www.mazda3revolution.com/threads/2014-mazda3-fuel-tank-replacement.245797/

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.

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.

Mazda Motors North American Operations (Mazda) is recalling certain model year 2014-2016 Mazda3 vehicles manufactured January 4, 2014, to September 18, 2015. The fuel tank of the affected vehicles may have been improperly handled during manufacturing and, as a result, the welded attachment of the Inlet Check Valve (ICV) may fail and allow fuel to leak. Consequence A fuel leak in the presence of an ignition source increases the risk of a fire. This is what i seem to be experiencing please expand recall...

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.

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 NHTSA 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.
