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

Electrical System
Filed Oct 1, 2026CA

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.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
