Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2018 GLC300 4MATIC Coupe, GLC300, GLC300 4MATIC, GLC350e 4MATIC, GLC43 AMG 4MATIC Coupe, and GLC43 AMG 4MATIC vehicles equipped with LED headlights. The front turn signals may have an incorrect color of pink or violet. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

What's the problem?

In March 2018, a vehicle was located in the production plant with nonconforming turn signal colors. Following an investigation with the headlamp supplier, a production problem was discovered that resulted in damage to the LED phosphor layers that caused the color variations.

Turn signals that are the wrong color may not be as easily recognized by other drivers, increasing the risk of a crash. Approximately 4,702 vehicles are involved in this recall.

What happens next?

MBUSA will notify owners and dealers will inspect the color of the turn signal. If an incorrect turn signal color is found, dealers will replace the LED module free of charge.

The recall is expected to begin November 9, 2018. Owners may contact MBUSA customer service at (800) 367-6372.
