The 2019 Mercedes-Benz G63 has 4 recalls, the most serious involving a software fault that can cause the engine to stall unexpectedly, raising the risk of a crash.
Two recalls affect safety systems that need to work in a collision. The front door wiring harnesses may have been routed in a way that allows wires to wear and break as the doors open and close, which can disable the side impact airbags, prevent the doors from unlocking automatically in a crash, or cut off the vehicle's location signal. Separately, the seatbelt pretensioners and the pre-crash tensioning system may fail to activate in a crash, reducing the protection they provide to occupants. There is also a label concern on the rear doors: the embossed child safety lock symbol may show the wrong lock status, meaning a caregiver could believe the lock is engaged when it is not, and a child could open the door while the vehicle is moving.
