2026 Mercedes-Benz GLC-Class problems, recalls and owner complaints

While loading grocery bags in the rear compartment the hatch closed on my back without any warning. I had to physically lift it off my back. It did not trigger any release or raise on its own

The MBUX/center display has malfunctioned repeatedly. The enter display suddenly went to completely black on the three separate occasions, and on one additional occasion three times. MBUX system froze and became completely unresponsive. These are four separate incidents, not a one-time occurrence. The failures occurred without warning and the system could not be operated normally. This creates a safety concern because loss of the center display while driving may prevent access to vehicle information, warnings, camera functions, and other functions controlled through the display. The vehicle is…

the MBUX infotainment screen goes completely black while driving, blinding the backup camera and critical driver instrumentation.

While driving at slow speed (approx 27 mph) on an inclining road, the automatic braking system when off and abruptly slowed down the vehicle. Fortunately there was no one immediately behind my car and there was no apparent reason for the emergency braking. The sidewalk did have a person with a dog off to the right at the time but they were completely away from the car walking on a sidewalk. This could have been dangerous if someone was driving immediately behind my car.

I was parked for a few minutes and I suddenly noticed a strong oder coming into my vehicle. I could not pinpoint what the smell was, but I knew that whatever was coming into the SUV was not safe. My screen started flashing warnings "Service Required: Do Not Drive" “Do Not Shift Gears”. After the warning, white smoke started to roll out from under the hood and into the vehicle. I immediately ran back to get my baby out of her car seat and to safety. I was at my local YMCA and staff ran out to I assist me and had a fire extinguisher. YMCA called the police and fire department. Both were…

I bought a 2026 GLC300 4matic SUV a month ago. I am very disappointed and scared of serious bodily damage due to the trunk door closing by itself while my upper body is loading/unloading the trunk. My wife and I were hit on the shoulder, back, arms, or head over a dozen times for 1 month. We took the car to the dealership for the problem but did not hear back from them for 3 days. The loaner car the dealership provided which is also 2026 GLC300 SUV also closes on me in the trunk. When the trunk shuts by tself while part of my upper body is in the trunk, it is impossible for me to stop it. It…

The breaks on these vehicles are extremely dangerous . Before I leased this vehicle test drove 3 vehicles. The salesman said the breaks will adjust as you drive. They have not. ITS all over the internet that this vehicle has very unresponsive breaks. It takes 75 precent of pressure pushing down on the break pad distance before the car breaks engage. I already almost had an accident as the distance it takes for the car to respond is a significant distance before the car comes to a full stop. I have brought back the car to my dealership three times expressing my displeasure and each time I m…

This happened four times in the eight weeks since pick up of vehicle as brand new. This could have cause a crash or caused vehicle to strike an object or person. Vehicle accelerated on its own and was difficult to…
