Owner report 11695851 · 2025-10-27 (October 27, 2025)
The instrument panel behind the steering wheel has gone totally dark. This issue happened about a month ago but resolved itself somehow. Issue happened again and will not correct itself. Took vehicle to dealer and they could not resolve issue with software update. Upon researching the MBWorld.org user forum I noticed this may be a wide spread issue. With a dark/blank instrument panel you cannot know your speed, fuel level, or what gear you have placed the car in. My technician even indicated he has seen this issue on several 2025 MB models.

Owner report 11721877 · 2026-03-04 (March 4, 2026)
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…

Owner report 11729806 · 2026-04-07 (April 7, 2026)
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.

3 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
25V379000 · Structure:Body:Roof And Pillars
Reported: 2025-06-06 (June 6, 2025)
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2023-2025 GLC 300, GLC 300 4MATIC, 2024-2025 AMG GLC 43 4MATIC, 2025 GLC 350E 4MATIC, and AMG GLC 63 S E vehicles equipped with a panoramic sunroof. In certain crash scenarios, where the rear occupant's head contacts the C-pillar, the pillar may not absorb an adequate amount of the impact. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 201, "Occupant Protection in Interior Impact."
Consequence: In the event of a crash, insufficient impact protection can increase the risk of injury.
Remedy: Dealers will modify the roof lining and C-pillar trim, free of charge. Owner notification letters were mailed July 9, 2025. Owners may contact MBUSA customer service at 1-800-367-6372.
