As NHTSA's recall record states it for campaign 15V621000.
Defect description
Mazda North American Operations (Mazda) is recalling certain model year 2015-2016 Mazda3 vehicles manufactured May 21, 2015, to August 25, 2015. The affected vehicles are equipped with a fuel tank with a shut-off valve that can allow fuel to enter into the fuel tank emissions systems. If enough fuel enters the emission system it may leak out onto the ground or result in an engine stall.
Safety consequence
A fuel leak in the presence of an ignition source increases the risk of a fire. An engine that stalls increases the risk of a crash.
Manufacturer remedy
Mazda will notify owners, and dealers will inspect the vehicle's fuel shut-off valve. As needed, the fuel shut-off valve and the affected fuel tank emissions system components will be replaced, free of charge. The recall began on October 20, 2015. Owners are advised not to drive their vehicle until the repairs have been completed. Mazda will provide rental cars until that time. Owners may contact the Mazda Customer Experience Center at 1-800- 222-5500, option #6. Mazda's number for this recall is 8615J.
