What can fail
A software error in the communication module's SIM card can prevent mobile network connection, which disables the emergency call (eCall) system.
The 2019 Mercedes-Benz AMG S63 has 7 recalls, the most serious being a turbocharger oil line that can leak onto hot engine or exhaust components and start a fire.
A structural recall covers roof panel adhesive that can deteriorate and allow the front panel to detach from the vehicle while driving, becoming a hazard for other traffic. On the occupant safety side, the seatbelt pretensioners may not activate in a crash, reducing the restraint the belt provides at the moment of impact. The automatic emergency braking system may also fail to apply partial or full braking when it detects a collision risk ahead, leaving the driver without that backup intervention. Two related recalls address the automatic crash notification system: in one, the system may be disabled entirely and unable to reach emergency services; in the other, it may transmit an incorrect location, sending responders to the wrong place. There is also a driver assistance concern: the hands-off detection system can malfunction and leave the active steering assist engaged even when the driver has removed their hands from the wheel for an extended period.
