The problem
BMW of North America, LLC (BMW) is recalling certain 2021 430i and M440i 4 Series Convertible vehicles. In certain side-impact crashes, the head-thorax air bag may not deploy as intended.
The risk
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. Owners may contact BMW customer service at 1-800-525-7417.
