The 2023 Mercedes-Benz GLS 580 has 4 recalls, the most serious being a fuel pump that can shut down without warning and cut drive power, leaving the vehicle unable to accelerate or maintain speed in traffic.
A separate electrical concern involves a 48-volt ground connection located under the passenger seat that may not be properly secured. A loose connection there can overheat and raise the risk of a fire inside the cabin. On the structural side, the rear door window trim bars can detach from the vehicle while driving, dropping debris onto the road and creating a hazard for other vehicles or pedestrians nearby.
