Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

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.
