Communication 2019-11-01 · campaign 19V787000 · 24,226 vehicles

Defect: 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.

Steering:electric Power Assist System 2016-12-14 · campaign 16V899000 · 70 vehicles

Defect: 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.

Fix: 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.

Air Bags:side/Window 2013-11-01 · campaign 13V542000 · 130 vehicles

Defect: Mercedes-Benz (Mercedes) is recalling certain model year 2013 SL63, SL550, and SL65 vehicles manufactured January 16, 2013, through April 30, 2013. The affected vehicles are equipped with an occupant classification system (OCS) that may not detect a very light person sitting in the front passenger seat.

Risk: If the OCS does not detect a very light person sitting in the seat, the passenger side air bag would be turned off. In the event of a crash necessitating side air bag deployment, the passenger would be at an increased risk of injury.

Fix: Mercedes will notify owners, and dealers will replace the passenger side seat cushion including the OCS. The recall began on December 20, 2013. Owners may contact Mercedes at 1-201-573-0600.

Service bulletins (87)

Technical service bulletins are repair instructions manufacturers send dealers for known issues. Unlike recalls, the fix is not automatically free — but naming the bulletin at the service desk can save diagnosis time and support goodwill repairs.
