On May 10th while driving on I-35 Texas highway, San Antonio Texas, the panoramic sunroof of our 2015 Mercedes Benz CLA 250 completely shattered while wife driving and daughter as a passenger, they heard a big bang and suddenly pieces of shattered glass fell all over the interior some of the glass hitting my wife and daughter in the face, they immediately pulled over to evaluate the situation. This could have caused an accident or significant injury. She had SAPD meet her at a gas station as she thought someone has shot at the glass, but officer confirmed that indeed the panoramic sunroof completely shattered. We tried to fix the panoramic roof and both Mercedes dealerships in San Antonio and Boerne Texas refused to repair the panoramic sunroof, we had to file a claim with our insurance and take the car to a collision center. The collision center stated that the sunroof was on back order from Mercedes Corp and had no timeline as to when the part would be available. Due to the car was not safe to drive and timeline on the parts, our insurance offered to total the car, but the car is almost new, low miles and in perfect mechanical condition so we declined. We received a call 4 months later that the car was fixed and the panoramic roof was installed.

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.

Incident on 10/18/21, while coasting into a parking space, my car suddenly accelerated and smashed into a concrete wall. Damage was extensive and car was determined a loss. Service was maintained throughout ownership. There was no warning, no lights, messages, no ABS brakes. Airbag did not deploy. Extensive seatbelt bruising. I'm upset car was a loss but I would never feel safe driving it. It was as if someone else had taken over control and I was powerless to alter the situation.

My collision assist keeps deactivating while driving. This causes my car to go into neutral. However there is not read of an issue with my vehicle per dealership

Blow-by gases are mixed with oil mist and other contaminants that can harm an engine's internal components and contaminate the environment. How does the crankshaft ventilation work- When the vehicle is moving, airflow across the open end of the tube creates suction (a "draught" or draft) that pulls gases out of the crankcase. To prevent too much vacuum being created, the blow-by gases are replaced by fresh air using a device called a breather. The breather is often located in the oil cap. the engine misfires, you may have trouble getting your vehicle up to speed. Misfires often happen when your vehicle is under load while accelerating. This can result in slow or sluggish acceleration or a jerking motion while pressing down on the accel INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),

Normal driving, daily driver. The rubber around the inner and outer sidewalls seems soft and tears easily. I have a matching set of these tires on my car, same brand and type, 4 altogether. I have multiple large torn chucks & tears in the rubber around the sidewall of these tires. The middle section (non-sidewall) seems fine with normal wear. I have lifetime alignment and rotate and balance on these tires when purchased, and maintain this service. I have not seen this issue on other continentals in the past, and the wear is excessive on this brand.
