Mazda North American Operations (MNAO) has filed a defect notification with the National Highway Traffic Safety Administration (NHTSA) for a safety defect, which exists in certain 2020 Mazda CX-30 vehicles when equipped with all-wheel drive (AWD). Mazda’s recall number is 4520F. On certain vehicles equipped with AWD, the fuel evaporative vent hose may not be connected to the fuel sender unit due to an improper manufacturing process at the fuel tank manufacturing plant. When fully refueling the vehicle, liquid fuel will eventually fill the charcoal canister, resulting in a leak.
A fuel leak from the canister in the presence of an ignition source may increase the risk of a fire. Additionally, the engine may stall while driving, increasing the risk of a crash. A Malfunction Indicator Lamp (MIL) and warning messages in the Multi- Information Display and Active Driving Display may notify the driver of a malfunction in the vehicle emissions system if this defect occurs.
Approximately 12,097 Mazda CX-30 units are affected in the U.S..
No accidents or injuries have been reported from the field to date as a result of this defect.
