BMW of North America is recalling 21 model year 2020-2021 M2 Coupes and model year 2020 M4 Coupes.
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.
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.
What to do
BMW will notify owners, and dealers will inspect the fuel injectors. If a damping component is missing, the injectors and the fuel rail will be replaced free of charge.
The recall is expected to begin December 21, 2020.
Owners may contact BMW customer service at (800) 525-7417.
