In November 2024, while at a stop, the car shut off. A few weeks later, while driving the car over speed tables/humps, the car shifted from drive into neutral. No warning or error lights appeared on the dashboard. It just showed that the car was now in neutral. I was able to shift back into drive and continue. Fortunately, I was in a residential neighborhood, going about 10 miles per hour and had only one car behind me. This happened again in December, with the same scenario and on the same road, so I took the car to the dealer. They did a diagnostic and was not able to duplicate the problem, but said there were some error codes and it could possibly be the starter, auxiliary battery or transmisson service, since I had not done one. They also stated there was a Coolant Thermostat electrical fault code. They scheduled me to come back in January 2025 since I needed a loaner car. They kept my car for a couple of days to do a more detailed diagnostic. In the end they replaced the auxiliary battery and did a transmission service because they could not replicate the problem. Said that there was nothing in the transmission fluid of concern and, the starter code had not returned. Stated that it could have been an electrical fluke. No other codes were showing. They did say that some time in the future I would need a coolant thermostat. Car ran well for a few weeks and then in February 2025, going over the same road with speed humps, the car went into neutral. The car has been in the shop for the last 7 days and they are trying to figure out what is happening. I am submitting this because I found many other people posting on forums about having the same issue. My concern is what will happen if my car moves into neutral while I am going at a high speed. It puts me, my family and others lives in danger if my car stops suddenly.

The head unit for the sound system begins a reset loop when navigating radio station and/or connecting bluetooth device. Seems to be a glitch in the head unit software. This is preventing use of navigation/GPS screen, backup camera, and Bluetooth connection.

Ml 250 blu tech diesel. 55,000 miles. Vehicle had been previously maintained only by Mercedes Benz and every recommended service had been completed timely by only Mercedes Benz. 1 month out of warranty and the car was inspected by Mercedes 30 days prior and given a clean bill of health. No warning lights ever came on prior to or during the incident. This complaint is very similar to another on your website also involving the same parts. Vehicle was completely stopped at a major 4 way intersection. When I tried to make a left turn a horrible loud grinding noise was heard from the back of the vehicle. The vehicle just seized. When I tried to go shift into park, the brakes failed to work, steering was incredibly difficult. The car had to be pushed off the highway and towed to Mercedes. Diagnoses was front drive shaft broken and 2 rear coil springs broken simultaneously. I have had many vehicles never had I heard of a drive shaft breaking at 55,000 and certainly never simultaneously with rear coil springs. The car is driven under normal circumstances, no towing no excessive weight, etc. Mercedes was contacted, the offered a 5% discount as a "good will" gesture but refused to stand behind their product and advised this was not part of a prior recall. They further stated when the car was checked 30 days prior the drive shaft and coil springs are not discover-able.
