Mercedes-Benz USA (MBUSA) is recalling 129 model year 2021 GLC 300s, GLC 300 4Matics, AMG GLC 63 4Matics, AMG GLC 63 S 4Matics, and AMG GLC 43 4Matics.
The electrical connection for the headlights may not be watertight, which can result in headlight failure.
Headlight failure can decrease visibility for both the driver and surrounding traffic, increasing the risk of a crash.
What to do
Dealers will inspect and replace the headlight sealing plugs -- as necessary -- free of charge.
Owner notification letters are expected to be mailed on June 14, 2022.
Owners may contact MBUSA customer service at (800) 367-6372.
