Mercedes-Benz CLS 550 Recall 15V137: Rear side lights may not illuminate, raising crash risk

NHTSA campaign 15V137, reported March 10, 2015, 30,141 vehicles potentially affected.

What this recall means for you

Certain Mercedes-Benz CLS models have LED tail lights that may not light up on the sides. This reduces the vehicle's rear side visibility and means it does not fully meet Federal Motor Vehicle Safety Standard No. 108 for lamps and reflective devices.

With reduced side illumination at the rear, other drivers may have a harder time seeing your vehicle, which increases the risk of a crash. Mercedes-Benz USA will notify affected owners directly.

The remedy is a free software update to the lighting controller, performed by an authorized dealer. You can contact Mercedes-Benz USA customer service at 1-800-367-6372, and you should check your VIN for any open recalls.
