Recall 18V610 covers 4,702 2018 Mercedes-Benz GLC vehicles with wrong-color front turn signals. Repair is free at any franchised Mercedes-Benz dealer.
Mercedes-Benz is recalling 4,702 2018 Glc 350 E, Glc 300, and AMG GLC43 vehicles with LED headlights because the front turn signals can show pink or violet instead of the required color. That color problem makes the signal harder for other drivers to recognize and increases crash risk; the Mercedes-Benz dealer repair will be free once available.

What's wrong?
The front turn signals on these 2018 Mercedes-Benz Glc 350 E, Glc 300, and AMG GLC43 vehicles are part of the LED headlight assembly. Their normal job is to flash in the required signal color so people outside the vehicle understand when the driver is turning or changing lanes.
In the affected headlights, a supplier manufacturing error damaged the phosphor layers inside the turn signal LEDs. That damage changes the visible color spectrum, so the turn signal can show pink or violet instead of the required turn signal color. Mercedes-Benz traced the issue to suspect headlamp batches and identifies the correct repair as an LED module built to specification.
Owners can notice the problem when locking or unlocking the vehicle, because the turn signal lights flash during that action. If the lamps show pink or violet instead of the normal signal color, that is the warning sign to report to a Mercedes-Benz dealer.

What's the safety risk?
Turn signals in the wrong color are harder for other drivers to recognize. That raises the risk of a crash when nearby drivers cannot read your intent to turn or change lanes. If you see the wrong turn-signal color, schedule inspection soon. Repair will be free at any franchised Mercedes-Benz dealer once available.
