The 2022 Mercedes-Benz AMG GLS63 has 4 recalls, the most serious being a fuel pump that can shut down without warning, cutting drive power and leaving the vehicle unable to accelerate or maintain speed in traffic.
A loose 48-volt ground connection under the passenger seat poses a fire risk. The connection can overheat when not properly secured, raising the risk of a fire starting inside the cabin area. On the structural side, the rear door window trim bars can detach from the vehicle at speed and become a road hazard for other drivers, raising the risk of a crash or injury. Prior repair attempts for the fuel pump issue did not fully resolve the problem, which is why it appears across more than one recall campaign affecting this vehicle.
