## What is wrong

BMW of North America, LLC \(BMW\) is recalling certain 2018\-2019 X3 sDrive30i, X3 xDrive30i, X3 M40i and 2019 X4 xDrive30i, and X4 M40i vehicles.  The front passenger seat occupant classification system may have been improperly assembled, which could result in the misclassification of the seat as unoccupied, and deactivate the front air bag.


## What can happen

A deactivated front air bag will not deploy in the event of a crash, increasing the risk of injury.


## The remedy

Dealers will replace the seat foam, which includes the occupant classification system, free of charge.  Owner notification letters were mailed on September 3, 2021.  Owners may contact BMW customer service at 1\-800\-525\-7417.
