2018 MERCEDES-BENZ S CLASS Recalls — Canada & USA

The 2018 Mercedes-Benz S Class has 6 recalls, with the most serious being engine and electrical issues that can cause sudden power loss or a fire risk from unsecured power bar connections in the trunk's fuse box. Three recalls affect specific trims on the engine side. On S 560 and Maybach S 560 models, oil port plugs can fail and allow oil to leak; if the level drops far enough and the driver continues, the engine can seize and cut power without warning. On S 560 4Matic models, a timing chain bolt can loosen, causing the chain to skip and the engine to stall or fail while driving. On the drivetrain side, the driveshaft on certain vehicles may wear prematurely and shed its universal joint, cutting power to the wheels. Two driver assistance recalls round out the list: a software fault can prevent the Active Lane Keeping Assist system from steering the car back toward its lane during an unintended departure at highway speeds, and a mispositioned steering boot on S-Class, AMG S 63, and Maybach S 560 models can cause the hands-off detection feature to stop recognizing when the driver has let go of the wheel.
