Has the 2020 BMW M4 been recalled?
2 U.S. safety recalls. Repairs are free at a franchised dealer; some are done over the air.
Fuel System, Gasoline: Fuel Injection System 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.
Risk: 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.
Fix: 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.
Air Bags: Knee Bolster BMW of North America, LLC (BMW) is recalling certain 2019-2020 230i, 230i xDrive, M240i, M240i xDrive, M2 Competition Coupe, 430i, 430i xDrive, 440i, 440i xDrive, M4, and 2019 330i xDrive Sportswagon vehicles. The driver and passenger knee air bag assemblies may have been improperly folded and assembled.
Risk: An improperly folded and assembled air bag may not deploy as intended, increasing risk of injury.
Fix: BMW will notify owners, and dealers will replace the knee air bag modules, free of charge. The recall began July 8, 2019. Owners may contact BMW customer service at 1-800-525-7417.
