Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2017 E300, E300 4Matic, and E43 AMG vehicles. The front passenger occupant detection control unit may have been incorrectly installed. As a result, the front passenger seat occupant may be misclassified. For example, an adult may be misclassified as a child seat, causing the front passenger air bag to be deactivated in the event of a crash.
If the passenger front air bag does not deploy as intended in the event of a crash, it can increase the risk of a injury.
MBUSA will notify owners, and dealers will inspect the routing of the pressure hose of the seat occupancy detection control unit and replace the pressure hose and seat occupancy detection mat if necessary, free of charge. The recall began March 2017. Owners may contact MBUSA customer service at 1-800-367-6372.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
