Information screens; speed, gear etc. and middle screen, radio, gps, etc, go blank. Screens are black with no information. There’s also a popping sound happening in the background over the speakers. You can start the car and put it in gear and drive - but with no information in either computer screens. Safety issue for sure! After waiting approximately 3 hours, the 2 screens come on when car is started.

The screen goes blank not only in the middle where the maps, air conditioning and radio is but the screen where the speed gas tank are as well. We have taken the car in at least 5 times stayed the issue and were told there’s no recall yet for the car. I see here that there is. The car was a Richmond Mercedes today the screen went down amd I was told there’s no fix but maybe I could look on the internet. So here I am!

My vehicle's infotainment system both center console and dashbboard went completely black 2 weeks after I purchased the car in August of 2025. The vehicle was in the shop for a week and a half, and they finally fixed the issue. The vehicle at the time was bought used with about 2,200 miles on it at time of purchase. Now in July of 2026, exactly one year from the day i bought the car, with only 9,500 miles on it, we are having the same issue again with both the dashboard and center console going completely dark, not allowing us to see any critical information such as MPH, gas fuel, tire pressure, etc. Other than that the car seems to drive just fine. I noticed there was a mass recall of 144,000 cars because of this same issue with Mercedes Benz. The GLC-class was in fact listed on this list of eligible recall vehicles. However my VIN # was not eligible for some reason, even though it is the exact issue that the recalls were happening on, and fits within the recall class type and year of manufacture (2024-2026). I am simply requesting to be put on this recall list because it seems like this issue will continue to persist and we do not want to be turning this in every year and also risk our lives driving a car that does not give us very critical information in order to drive safely.

In multiple incidents, the tailgate has begun to close while I am loading or unloading items from the trunk, hitting me in the head. My natural reaction is to lift up, causing injury to my neck. The dealer unsuccessfully "fixed" the problem. Additionally, and unrelated to the closing problem, on multiple occasions, upon pushing the close button on the tailgate when it was in an open position, the tailgate reaches the floor of the trunk, then without locking, opens about one (1) foot. The dealer "could not duplicate" the problem. I have to manually close the tailgate. You ask when did this happen, the latest incident is the date reported below, but the two issues/problems have reoccurred time and time again since we bought the vehicle new.

The infotainment and instrument panel screens blacked out after the vehicle was started a few miles away from our home. I was unable to see the speedometer while driving back home. This was the first time that this has happened to us. After a Google search of Mercedes Benz 2025 GLC 300, this event appears to be fairly common.

When I entered my vehicle after it was washed at the Mercedes-Benz service location, I pressed Memory 1 button and the seat returned to my normal position. Without any further input, I started the engine, and the driver's seat automatically moved backward by itself. When I readjusted the seat and shifted into Drive, it continued moving rearward. As the seat moved backward, my feet could no longer reach the brake pedal. At the same time, the car began to move forward, and I lost control of the vehicle, resulting in a collision that damaged the right side doors. This malfunction occurred suddenly and without any warning lights or messages. The seat moved by itself twice-once when the engine started and again when I shifted into Drive. The issue appears to be related to the seat's electrical control system or memory setting malfunction. The dealership has inspected the vehicle but was unable to determine the cause of the problem. I am deeply concerned that this may happen again and could cause a serious injury or major traffic accident. The vehicle has approximately 2200 miles and was purchased new in March 2025. I am requesting a formal investigation to determine the cause of this automatic seat movement and whether other vehicles of the same model are affected.

The entire main console display AND the digital instrument cluster screen have completely frozen. Additionally, the gas gauge for how much fuel is in the vehicle is nowhere to be found. Temperature touch controls (no physical option), volume, car settings (which can adjust safety features, multimedia features, accessibility features), etc. are all completely unavailable and unable to use. For example, if the defrost option was on which defaults to full blast heat, I would’ve unable to turn it off. The only information that is properly updating is MPH, headlamp status, time, Emerfency brake, Gear, and outside temperature. RPMs cannot be seen. Some of the pictures attached show that I’ve been on a phone call for 3.5 hours. I’m not.
