Example complaints

Electrical system: “The component that repeatedly fails is the vehicle’s electronic display/infotainment system (dual digital screens/MBUX system) and potentially related electrical components in my 2025 Mercedes-Benz GLC 300 4MATIC. The system has malfunctioned six (6) separate times since I purchased the vehicle new in May 2025. When the malfunction occurs, both display screens suddenly go completely black and become inoperable while the vehicle is running. During these failures, the vehicle also produces a repetitive clicking sound from the dashboard area while the screens are off. …”

Forward collision avoidance: “To the Office of Defects Investigation National Highway Traffic Safety Administration I am submitting this complaint to formally report a serious and recurring safety defect involving the automatic braking and collision detection systems in our Mercedes-Benz GLC. …”

NHTSA complaint #11723692, filed 2026-03

Body and structure: “The liftgate on this car is faulty. There are hundreds of reports online that I found when it happened to me, which has been several times now. The liftgate has a sensor that is activated by your foot, but when you are inside the hatch it will trigger and close on you. There is no sensor to stop it from falling and it traps you inside and has hit me on the head, bruised my shoulders and back and I have fallen from being hit by it. I have reported it to Mercedes several times and asked them to at least cover the sensor and they say it's not possible. …”
