Certain 2010-2012 Mazda6 vehicles equipped with 2.5L engines could be affected by a problem in the fuel system that could lead to fuel leaks and an increased chance of a vehicle fire. Mazda will be notifying owners to take their vehicles to their dealership to have the fuel system inspected and to reprogram the power-train control module.

On certain Mazda6 vehicles, the evaporator canister vent line could become restricted because of a spider weaving a web in the line. If this occurs, the fuel tank pressure could become excessively negative when the emission control system tries to purge the vapors from the canister. As the canister is purged repeatedly during normal operation, the stress on the tank could result in cracks. These cracks could lead to fuel leaks and an eventual fire.

Mazda will notify owners to take their Mazda6 vehicles to a dealer to be inspected and repaired. The canister vent line will be cleaned and when there is a web in the canister vent line, the fuel tank and the check valve on the canister vent line will be replaced. The power-train control module will be reprogrammed with modified software to minimize negative pressure in the fuel tank. Owners wanting more information about the problem can contact Mazda at 1-800-222-5500. Mazda’s recall number is 7214C and the NHTSA campaign number is 14V-114.
