Mercedes-Benz USA (MBUSA) is recalling 26,116 model year 2019-2021 G550s and AMG G63s.
The front axle wiring harness may chafe against an oil cooler and become damaged, which can cause a loss of anti-lock brakes (ABS) and electronic stability control (ESC).
The loss of either can increase the risk of a crash.
What to do
Dealers will inspect and either install a protective sleeve or replace the front axle wiring harness -- as necessary --free of charge.
Owner notification letters are expected to be mailed April 18, 2023.
Owners may contact MBUSA customer service at (800) 367-6372.
