What's wrong: Mercedes-benz USA, LLC. (mbusa) is recalling certain model year 2015 cls 400 and cls 400 4matic, 2012-2015 cls 550 and cls 550 4matic, 2012-2013 cls 63, 2014 cls 63, and 2014-2015 cls 63p. The affected vehicles have LED tail lights that May not light on the sides, reducing the rear side visibility of the vehicle. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard…
Why it matters: Reduced rear side marker illumination May prevent other drivers from seeing the vehicle, increasing the risk of a crash.
The fix: Mbusa will notify owners, and dealers will update the lighting controller software, free of charge. The recall began April 6, 2015.
