Recalls

1 vehicle recall from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.

Seat belts Vehicle recall #17V507000 · 2017 · 67 vehicles

What's wrong: The emergency locking retractors (elr) within the front seat belt assemblies May have been produced with incompatible vehicle-sensitive locking mechanism housings.

Why it matters: If the vehicle has an incompatible vehicle-sensitive locking mechanism, the seat belt May not restrain the seat occupant in the event of a crash, increasing the risk of injury.

The fix: Bmw will notify owners, and dealers will inspect and, if necessary replace, the front seat belt assemblies, free of charge. The recall began October 13, 2017.
