Units affected
24,226 (estimate)
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.
Remedy
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.
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2013-2015 SL550, 2013-2014 SL63 AMG, 2014-2016 E350, 2014 E350 Cabriolet, E350 Coupe, 2014-2015 S550, 2015 E350 Bluetec, 2015-2016 E400, 2016 E550 Coupe, and Maybach S600 vehicles manufactured August 23, 2012, to August 14, 2015. The affected vehicles use an electric power steering system that may have improperly soldered contacts inside the control unit, potentially resulting in the power steering system deactivating while driving.
Risk
If the control unit pins lose connection, there would be a loss of electric power steering assist, increasing the risk of a crash. The increase in pin contact resistance can also increase the risk of a fire, even while the vehicle is parked and ignition is off.
Remedy
MBUSA will notify owners, and dealers will replace the electric power steering control unit, free of charge. The recall began October 13, 2017. Owners may contact MBUSA customer service at 1-800-367-6372.
Mercedes-Benz USA, LLC (MBUSA) is recalling certain model year 2016 SLK300, SLK350, SL400, SL550, and SL63 AMG vehicles manufactured from June 29, 2015, through July 13, 2015. The affected vehicles are equipped with low-beam headlights that may have been aimed incorrectly during vehicle production. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk
Improperly adjusted low-beam headlights may reduce the driver's visibility, increasing the risk of a crash.
Remedy
MBUSA will notify owners, and dealers will inspect and if necessary adjust the headlamps, free of charge. The recall began on July 22, 2016. Owners may contact MBUSA customer service at 1-800-367-6372.
