What is wrong

BMW of North America, LLC (BMW) is recalling certain 2020 X3 xDrive30e, X4 xDrive30i, X4 M40i, X4M, 330i, 330i xDrive, M340i, 840i Gran Coupe, 840i xDrive Gran Coupe, M850i xDrive Gran Coupe, M8 Gran Coupe, X3 sDrive30i, X3 xDrive30i, X3 M40i, X3M, and 840i xDrive Convertible vehicles. The sensors in the front seat belt buckles may inaccurately detect a belted occupant as unbelted, possibly causing the air bag and seat belt pretensioners to deploy improperly in the event of a crash.

What can happen

If the air bag and/or seat belt pretensioners deploy improperly in the event of a crash, there is an increased risk of injury to the driver and front passenger.

The remedy

BMW will notify owners, and dealers will inspect and replace the front seat belt buckles, as necessary, free of charge. The recall began May 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.
