The 2023 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.
An electrical concern also carries serious consequences: a 48-volt ground connection under the passenger seat may not be properly secured, causing it to overheat and creating a risk of fire inside the vehicle. On the structural side, the rear door window trim bars can detach from the vehicle while driving and become road debris, posing a hazard to other drivers and pedestrians nearby.
