SUMMARY:
Mercedes-Benz USA, LLC (MBUSA) is recalling certain model year 2016-2017 GL350 4Matic Bluetec, GL550 4Matic, GLE350 4Matic, GLE43 AMG Coupe, GLE450 4Matic, 2016 GLE300d 4Matic, GLE350, GLE350d 4Matic, GLE400 4Matic, GLE550e 4Matic, GLE63 AMG, GLE63 AMG 4Matic, GLE63S AMG 4Matic Coupe, and 2017 GLS63 AMG vehicles manufactured April 23, 2014, to May 10, 2016. The front passenger seat Occupant Classification System (OCS) calibration may be incorrect, and as a result, the system can incorrectly classify the occupant as a child seat, deactivating the front passenger air bag.
CONSEQUENCE:
If the front passenger air bag does not deploy as necessary in the event of a crash, the front passenger has an increased risk of injury.
REMEDY:
MBUSA will notify owners, and dealers will update the OCS software, free of charge. The recall is expected to begin in January 2017. Owners may contact MBUSA customer service at 1-800-367-6372.
NOTES:
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.
