The problem
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.
The 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.
The 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.
