NHTSA's recall notice

As NHTSA's recall record states it for campaign 20V666000.

Defect description

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.

Safety 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.

Manufacturer 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.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
