Mercedes-Benz USA is recalling 6,517 model year 2019-2020 G550 4MATICs and G63 AMG 4MATICs.
An electrical resistor within the differential locking module may malfunction, interrupting communication between the control unit and the differential locking actuator, possibly resulting in the deactivation of the Electronic Stability Program (ESP) and Anti-lock Brake System (ABS).
Deactivation of the vehicle stability control system or anti-lock brakes while the vehicle is being driven may increase the risk of a crash.
What to do
MBUSA will notify owners, and dealers will inspect the differential locking modules and replace them as necessary free of charge.
The recall is expected to begin April 14, 2020.
Owners may contact MBUSA customer service at (800) 367-6372.
