2021 Mercedes-Benz Amg Gls63 Recalls & Complaints

The 2021 Mercedes-Benz AMG GLS63 has 10 recalls, the most serious involving two fire risks: a fuel pump that can shut down without warning and cut drive power, and a 48-volt electrical ground connection under the passenger seat that can overheat and ignite.

On the safety equipment side, the third-row seatback locks may fail in a crash, leaving rear occupants without proper restraint. There is also a fire risk tied to the air conditioning drain hoses: if incorrectly installed, they can direct water into the passenger footwells, where it can corrode wiring or cause short circuits.

Several recalls affect electronics and visibility. The multimedia system software can cause the display to go black or restart on boot-up, leaving the backup camera with no image while reversing. The emergency call system has two separate issues: in one, the system may fail to connect to the emergency services center at all; in another, it may send responders to the wrong location. Interior switch illumination can also fail, making controls harder to find while driving.

On the exterior, rear door window trim bars may detach at speed and become road hazards. There is also a recall for the instrument panel switches losing their backlight, which can make them harder to locate and operate in low light.
