The 2015 Mercedes-Benz S550e has 4 recalls, the most serious involving two separate hybrid-system issues: the fuel pump can deliver insufficient pressure after running in electric mode, causing the gasoline engine to stall, and the vehicle can unexpectedly shift into park if the charging cable is misread by the system while the car is moving slowly.
The roof panel between the windshield and the panoramic sunroof may not have been bonded correctly during a prior repair and can detach while driving, becoming a hazard for other vehicles on the road. On the electronics side, a software fault in the emergency call system can cause it to report the wrong date, time, and location to emergency responders, potentially delaying help from reaching the right place in a crash.
