The problem
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2017-2018 GLC300, GLC300 4Matic, and GLC43 AMG vehicles. The fixed panoramic sun roof frontal and side plastic panels may have insufficient bonding, allowing the panels to separate during vehicle operation.
The risk
If the sun roof panels detach from the vehicle, it can increase the risk of a crash or injury for following traffic.
The fix
MBUSA will notify owners, and dealers will inspect the bonding on the sun roof panels, correcting it as necessary, free of charge. The recall is expected to begin December 2017. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2017110009.
