“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. …”
NHTSA complaint #11721877, filed 2026-03“All of the screens in the car failed to start. They remained black while the car was running. Turning the car off did nothing. Drove to a parking lot, turned the car off, got out, locked the car, waited 5 minutes and it still didn't come back. Had to do a reboot by holding the system power button for 10 seconds. This has occurred 3x in 9,200 miles.”
NHTSA complaint #11729806, filed 2026-04“The instrument cluster display went dark and has not been able to display any information such as speed in miles per hour, fuel gauge, and other important information needed to maintain safe driving.”
NHTSA complaint #11742067, filed 2026-06“Both dashboard screens went dark and remained so through 5 cycles of starting the car. Had no operating information whatsoever. Told by dealer that many 2025 glc-300's are experiencing the same problem.”
