Visibility: windshield
- What is wrong
- 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."
- Risk
- 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.
