The contact owns a 2025 Mercedes-Benz GLC 300. The contact stated that while her husband was driving at 5 to 10 MPH attempting to park the vehilce lunged forward traveling 20 feet and crashed into the house. The air bags deployed. No warning lights were illuminated , There was no injuries or fire. A police report was filed. The gas company was on the scene due to a gas leak. Additionally the vehilce was serviced for electrical issues. While reversing in the snow the vehilce lunged 20 feet and crashed into a unknown vehicle causing a scratch. The local dealer was contacted where the EDR was requested. The vehicle was not diagnosed or repaired. The vehilce was towed to a towing lot. The manufacturer was not contacted The failure mileage was approximately 17,107. The vehicle was deemed a total lost.

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 contact leased a 2025 Mercedes-Benz GLC300. The contact stated that while driving at 45 MPH, the instrument panel and the infotainment system screen turned black, and the vehicle made abnormal electrical snapping sounds. The vehicle was taken to the dealer, where two software resets were performed days apart; however, the failure persisted. The dealer informed the contact that upon performing a third software reset and replacing the circuit breaker fuse, the vehicle would be repaired. The dealer and the manufacturer were contacted and informed the contact that it was a common failure. The failure mileage was approximately 4,700.

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.
