17V079000 · Air Bags:Frontal:Passenger Side:Inflator Module | Visibility:Windshield

Reported: 2017-02-08 (February 8, 2017) · Model years: 2016

Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2016 GLE350 4Matic and GLS 450 4Matic vehicles. The windshield bonding may be insufficient and, as a result, the windshield may separate from the vehicle in a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection" and number 212, "Windshield Mounting."

Consequence: If the windshield detaches in the event of a crash, the passenger frontal air bag may not be supported properly after it deploys, increasing the risk of injury.

Remedy: MBUSA will notify owners, and dealers will replace the windshield, free of charge. The recall began March 2017. Owners may contact MBUSA customer service at 1-800-367-6372.
