2015 Mercedes-Benz S550 Recalls & Complaints

The 2015 Mercedes-Benz S550 has 5 recalls, the most serious being a loss of electric power steering assist and a roof panel that can detach from the vehicle and become a road hazard for other drivers.

The power steering concern involves control unit pins that can lose connection, leaving the driver with significantly heavier steering and reduced ability to maneuver. The roof panel issue covers two related scenarios: the front panel between the windshield and panoramic sunroof can separate if its adhesive bonding deteriorates, and a prior repair attempt on some vehicles may not have fully resolved the bonding problem, meaning the panel can still come loose. On the electrical side, a software fault can prevent airbags from deploying correctly in a crash. There is also a software issue with the emergency call system, which can transmit an inaccurate vehicle location and potentially delay emergency responders.
