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…
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. This is dangerous and it's going to seriously injure or kill somebody younger or more feeble.

Vehicle experiences a severe, abrupt jerk/jolt during deceleration around the 5th-to-4th gear downshift. The issue occurs consistently when slowing down. Dealership verified the condition on Repair Order #1906625 and confirmed a transmission flaw. Dealer stated software is required from the manufacturer with no ETA for release. The abrupt deceleration creates unexpected cabin jolting during normal traffic slowing.
- Electrical system
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.
- Electrical system
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.

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. License Plate: 9RHN710 Dealer Servicing Vehicle: Mercedes-Benz of Stevens Creek (AutoNation), San Jose, California The vehicle has repeatedly experienced unexpected and unprovoked braking events, including situations where the automatic braking system engages despite there being no vehicles, pedestrians, or visible obstructions present. The issues observed include: • Sudden automatic braking activation without obstruction • Unexpected vehicle deceleration during normal driving conditions • Repeated dashboard alerts indicating “Speed Severely Restricted” • Repeated Attention Assist / “Coffee Break” warnings during normal local driving • Sudden brake engagement when parking, accompanied by a loud mechanical noise These events create a dangerous driving condition, as unexpected braking could lead to a rear-end collision from vehicles traveling behind the driver. During one incident, the abrupt braking caused a severe jolt to the driver, resulting in whiplash symptoms that required medical evaluation and MRI imaging, which identified cervical strain. The vehicle has been brought to the authorized dealership multiple times for inspection and repair attempts. However: • The dealership has not been able to diagnose or repair the issue • Service visits have largely been documented as general inspections • No ADAS (Advanced Driver Assistance Systems) diagnostic or calibration report has been provided, despite the fact that the malfunction appears directly related to radar, camera, or collision prevention systems. We respectfully request that the Office of Defects Investigation review this complaint and determine whether further investigation into this issue is warranted.

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. The most serious incident occurred on February 17, 2026, when the screens shut down while I was driving and I detected a burning electrical smell inside the vehicle. This raised significant concerns about a possible electrical malfunction or fire risk. The digital display system provides critical driving information, including vehicle settings, safety alerts, and operational controls. When the screens shut down, the driver loses access to important vehicle information and control functions, which creates a potential safety hazard while operating the vehicle. This issue has been reproduced multiple times and the vehicle has been taken to Mercedes-Benz of Jackson, Mississippi for inspection and repair attempts on several occasions. The dealership has attempted repairs and indicated that they have opened a case with the Mercedes-Benz manufacturing department regarding the recurring electrical issue. Due to the repeated electrical failures, clicking sounds from the dashboard area, and the burning electrical odor detected while the vehicle was in operation, I am concerned that this issue may indicate a serious electrical defect that could potentially lead to overheating or fire. The malfunction occurs while the vehicle is being driven, which places the driver and passengers at risk. Because the display system repeatedly shuts down and the issue has occurred multiple times despite dealer inspections and repair

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.
