Recalls

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

Electrical Vehicle recall #20V761000 · 2020 · 812 vehicles

What's wrong: The connection between the 48-volt battery and the starter-generator May not have been assembled properly, which can cause increased electrical resistance at the connections.

Why it matters: Increased electrical resistance can increase the risk of a fire.

The fix: Bmw will notify owners, and dealers will inspect the connection between the 48-volt battery and the starter-generator assembly, replacing it if necessary, free of charge. The recall is expected to begin April 12, 2021.

Backup camera, Backup camera Vehicle recall #21V096000 · 2021 · 13,858 vehicles

What's wrong: When shifting into reverse, a small portion of the rearview image May be obscured, or the screen May not illuminate. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (fmvss) number 111, "rear visibility."

Why it matters: If the driver relies on only the rearview camera image, the missing or reduced rearview image view can increase the risk of a crash or injury.

The fix: Bmw will notify owners, and dealers will inspect the rearview camera software and update it if necessary, free of charge. The recall began April 16, 2021.

Airbags, Airbags Vehicle recall #21V176000 · 2021 · 1,850 vehicles

What's wrong: In certain side-impact crashes, the head-thorax air bag May not deploy as intended.

Why it matters: An air bag that deploys incorrectly can increase the risk of injury in a crash.

The fix: Dealers will update the software, at no charge. All affected vehicles are still in dealer inventory, and therefore no owner letters will be mailed. The recall began March 9, 2021.

Seat belts Vehicle recall #21V554000 · 2021 · 21,537 vehicles

What's wrong: The passenger seat belt automatic locking retractor (alr) May deactivate early, before the webbing fully retracts. As such, these assemblies fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "occupant crash protection."

Why it matters: During a crash, a seat belt retractor that does not function as intended increases the risk of injury.

The fix: Dealers will inspect the seat belt retractors (including the seat belts) and, if necessary, replace the retractors, free of charge. Owner notification letters were mailed on September 3, 2021.

Electrical, Seat belts Vehicle recall #23V584000 · 2023 · 144 vehicles

What's wrong: The receiver audio module control unit software May fail to properly generate audible seat belt warnings to the driver to fasten their seat belt. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "occupant crash protection."

Why it matters: An audible chime that does not properly alert the driver to fasten their seat belt increases the risk of injury in a crash.

The fix: Dealers will update the receiver audio module software, free of charge. Owner notification letters were mailed October 12, 2023.
