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 available for inspection. I have reported the problem to Mercedes-Benz and requesting dealer inspection and repair. The cause is currently unknown.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
