Known issues on the 2015 S550. The federal record holds six recalls for the 2015 S550. On certain 4Matic coupe versions built between late January 2014 and early April 2015, the front seat belts may have been swapped side to side, upsetting their locking angle and removing the passenger seat's child-seat restraint function. Certain cars needed control unit software updated because their air bags might not deploy as designed in a crash. Seat belts lead the 45 owner complaints with 8, ahead of structure with 6; 5 complaints reported a crash, 3 a fire and 4 an injury. Restraint system procedures and wiring diagrams address those areas.
