BMW of North America, LLC (BMW) is recalling certain 2020-2021 M2 Coupe and 2020 M4 Coupe vehicles. Fuel injectors may have been installed without a damping component which is used to reduce vibration. If a damping component is not present, vibration will increase at the connection between the fuel line and the fuel rail, which over time, can result in damage at the connection.
Consequence & remedy
Consequence: A damaged connection between the fuel line and the fuel rail could lead to a fuel leak and, in the presence of an ignition source, increase the risk of a fire.
Remedy: BMW will notify owners, and dealers will inspect the fuel injectors and if a damping component is missing, the injectors and the fuel rail will be replaced, free of charge. The recall began December 18, 2020. Owners may contact BMW customer service at 1-800-525-7417.
