Mercedes-Benz G63 (2018–2019)
What the hazard is
Communication between the control unit and the locking actuator may be shut down and the displayed status of the differential lock may be unreliable. This could also mean that the electronic stability program (ESP) and anti-lock braking system (ABS) are deactivated. Loss of proper operation of the differential lock and braking and traction systems may increase the risk of a crash in situations where these are being relied on, increasing the risk of injury or death of vehicle occupants and occupants of nearby vehicles.
