BMW X3 Recall 21V521: Passenger Front Airbag May Not Deploy in a Crash

NHTSA campaign 21V521, reported July 8, 2021, 138 vehicles potentially affected.

What this recall means for you

Some BMW X3 and X4 vehicles from 2018 and 2019 may have a front passenger seat occupant classification system that was improperly assembled. The system can wrongly detect the seat as empty, which turns off the front passenger airbag.

If the airbag is deactivated, it will not deploy in a crash, which raises the risk of injury to a front passenger. Owners should be aware of this problem and have the repair done promptly.

Authorized BMW dealers will replace the seat foam, which includes the occupant classification system, at no cost to the owner. Owner notification letters were mailed on September 3, 2021. You can also contact BMW customer service at 1-800-525-7417, and check your vehicle identification number (VIN) for open recalls.
