The affected vehicles were manufactured from Oct. 9 through Nov. 20, 2012; check your vehicle’s build date on driver-side doorjamb sticker. In these cars, the OCS incorrectly classifies a very light person as being a child and deactivates the airbag. This increases the risk of injury to the passenger in the event of a crash.
Mercedes-Benz will start notifying all affected owners this month, and dealers will replace the passenger side seat cushion and the OCS for free. Owners can call Mercedes-Benz at 800-367-6372 or NHTSA’s vehicle safety hotline at 888-327-4236 for more info.
