Communication
Problem: Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2013-2017 vehicles due to a software fault that may cause the date and time for the emergency call system (eCall) to differ from the actual date and time, potentially relaying an inaccurate vehicle location. For a full list of the affected models visit: https://static.nhtsa.gov/odi/rcl/2019/RMISC-19V787-4620.pdf
Risk: An inaccurate vehicle location may delay emergency responders, increasing the risk of injury.
Fix: MBUSA has initiated an Over the Air (OTA) remote update. MBUSA will also notify owners, and dealers will check software for a successful OTA or update the communication module software as needed, free of charge. The recall began December 23, 2019. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2019120008.

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."
Risk: Reduced rear side marker illumination may prevent other drivers from seeing the vehicle, increasing the risk of a crash.
Fix: 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.
