15V137000 · Exterior Lighting
Reported: 2015-03-10 (March 10, 2015)
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 (FMVSS) No. 108, "Lamps, Reflective Devices, and Associated Equipment."
Consequence: Reduced rear side marker illumination may prevent other drivers from seeing the vehicle, increasing the risk of a crash.
Remedy: MBUSA will notify owners, and dealers will update the lighting controller software, free of charge. The recall began April 6, 2015. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2015030005.

the car started showing a low coolant message around 2017 about twice a year. I felt it was too often the message would come up. I would too off coolant each time to address it without seeing any leaks ever under the car. then 2018 thru 2019 the message would appear about 3 or 4.times per year. had it checked by Mercedes service and they advised nothing was leaking from the car and found no codes indicating urgency in repair to address. my car started failing to turnover after cranking and in July 2021 it failed to turnover at all ever again.…
