This morning, the National Highway Traffic Safety Administration published two recalls for the Mazda Mazda3--one covering a group of 2014-2016 model-year vehicles, and a second that only includes cars from 2016. Though the recalls are slightly different, both stem from problems with the Mazda3's fuel tank.
The first recall includes 2014-2016 Mazda3 vehicles built between January 4, 2014 and September 18, 2015. As the fuel tanks for those cars were being manufactured by Kautex Textron, they may have been improperly handled, and as a result, the weld on one of the tank's valves may have been weakened. In some cases, road vibrations may cause that weld to fail, which could lead to a fuel leak and a potential fire hazard.
The second recall affects 2016 Mazda3 vehicles manufactured between September 24, 2015 and October 16, 2015. As before, the fuel tanks in those vehicles may not have been properly manufactured by Kautex Textron, and as a result, one of their welds may also fail, leading to a fuel leak.
(For the curious, the weld in the first recall involved the Inlet Check Valve, while the second involved the recirculation pipe.)
A total of 17,484 vehicles are affected by the first recall, and 3,849 are affected by the second.
Mazda expects to mail recall notices to owners in both groups by November 1. Owners will be able to take their Mazda3s to Mazda dealerships, where the appropriate welds will be inspected and fuel tanks will be replaced, if necessary.
If you own one of these vehicles and have further questions, you're encouraged to contact Mazda customer service at 1-800-222-5500 and ask about recall #0116I (for 2014-2016 models) and recall #0216I (for 2016 models).
If you prefer, you can also call NHTSA's Vehicle Safety Hotline and ask about safety campaign #16V684000 (for 2014-2016 models) and recall #16V685000 (for 2016 models).
