BMW X5 triple warning lights for ABS, brakes, and 4x4 activated, possible issues with transfer case motor or ABS module on BMW X5

Some BMW X5 owners report experiencing warning lights for ABS, brake, and 4x4, indicating potential issues with the transfer case motor or ABS module. These warning lights may be triggered by a faulty plastic actuator gear in the transfer case actuator motor, a known problem in X3 and X5 models with the ATC350 transfer case. Additionally, common issues leading to the ABS light activation include short circuits, broken wires, blown fuses, or malfunctioning wheel speed sensors. When the ABS light is illuminated, it signifies that the anti-lock braking system is disabled, although the vehicle can still be braked without ABS. However, if the brake light also appears, it signals a serious malfunction in the braking system, requiring immediate attention to prevent brake failure. It is crucial for owners to address these warning lights promptly and seek inspection from a qualified mechanic to ensure safety and proper vehicle functioning.
