The problem
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.
The risk
A fuel leak in the presence of an ignition source increases the risk of a fire.
The fix
Mazda will notify owners, and depending on the tank lot number, dealers will inspect the ICV weld, replacing the fuel tank, as necessary, free of charge. The recall began November 1, 2016. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 0116I.
