The 2021 Mercedes-Benz AMG GLC63 S has 3 recalls, the most serious involving the fuel pump, which can shut down without warning and cut drive power to the wheels while the vehicle is in motion.
The seatbelt pretensioners on certain vehicles may not function properly in a crash, meaning the belts may fail to pull occupants firmly into their seats at the moment of impact, raising the risk of injury. There is also a concern with the headlights: the electrical connections where the headlight wiring seals against moisture are not fully watertight on some vehicles, allowing water to reach the connector and cause the headlights to fail, leaving the driver with reduced or no forward lighting and making the vehicle harder for other drivers to see at night.
