Known issues on the 2018 GLS63 AMG. The federal record holds three recalls for the 2018 GLS63 AMG, including one with a direct effect on stopping: certain vehicles have rear brake caliper pistons that may lack the correct coating, allowing gas to enter the rear hydraulic circuit briefly and reduce braking, so dealers bleed the rear brakes. The other two involve emergency call software on certain vehicles, one where a SIM card software error could drop the mobile connection and one where the module could send an incorrect location. Of the 2 complaints, 1 concerns service brakes. Brake hydraulics, eCall wiring, torque values and diagnostics are documented.
