Yes, four of the five physical sheared lug bolts are preserved and immediately available for independent forensic laboratory inspection upon request. 2. The left front wheel assembly separated while operating the vehicle on a public roadway at speed. This caused an immediate loss of directional vehicle control and severe chassis instability, posing an imminent, life-threatening risk of a high-speed rollover, collision with oncoming traffic, or total wheel detachment on a major highway. 3. Yes. Following the incident, the vehicle was towed directly to B&H Auto Body. Their certified technicians physically inspected the remaining wheel hubs on-site and confirmed in writing that widespread over-torquing of lug fasteners was present across the vehicle's remaining wheel assemblies. 4.

ENGINE
I own a 2014 Mercedes-Benz CLA 250 with the 2.0L turbocharged 4-cylinder M270 engine. The check-engine light came on and an OBD-II scan showed fault code P052E / P052E71, which indicates that the valve for crankcase ventilation (PCV / crankcase ventilation valve integrated into the valve cover) has a malfunction and the actuator is blocked. The vehicle is available for inspection and, if the repair is performed, the failed part can be retained. This appears to be the same failure that has been documented by other owners and by Mercedes-Benz on the related M274 engine used in other models (same 2.0L turbo engine family and PCV / crankcase ventilation design, but in a longitudinal layout). For those vehicles, Mercedes has issued technical service bulletins and extended emissions-related warranty coverage for the crankcase ventilation / PCV system, but vehicles like my CLA with the M270 engine are excluded even though they show the same DTCs and failure. In my case, the problem has so far shown up as a check-engine light and stored fault codes, without obvious drivability symptoms yet. However, a blocked or failed crankcase ventilation valve can increase crankcase pressure, cause oil leaks, fuel vapor or oil smells, and potential turbocharger or drivability issues, which may create a safety risk if the problem worsens (loss of power or stalling). The problem has been reproduced multiple times with different OBD-II scan tools. I contacted Mercedes-Benz and was told there are no recalls or warranty coverage for this issue on my vehicle.

UNKNOWN OR OTHER
I was driving down the highway without any vehicles in front of me at around 65mph when all of a sudden my panoramic roof exploded out of nowhere, it sounded like a gunshot going off inside the car and I nearly crashed my vehicle from the sudden explosion, I luckily had the glass shade cover up and glass did not fall in my face, I had my [XXX] daughter and [XXX] son in the backseat and they are now terrified to get back into any vehicle. This is extremely dangerous situation and will cause a serious accident in the future if not fixed. Nothing hit my roof and I wasn’t even using it at the time no one touched the thing, it just exploded out of nowhere.

I purchased my vehicle early March from Carmax. They offer a 90 day guarantee on anything that will go wrong with the vehicle full coverage. My daughter was having my grandchild so what a great opportunity but to drive my new vehicle from Chicago to Florida to give it a good run when I arrived I was having problems with the Eco drive, which is the start stop enabler. The car would die out. Also, there were a few alarms as far as the temperature of the vehicle and the service mechanism being that I had left at the dealership at 9:30 PM at night and hit the road immediately I had to notice until the morning, but there was some cracking on the exterior of the driver side tire. Upon arriving to Florida. I brought the car directly to Mercedes at the Daytona auto Mall soon as I walked in they service representative stated we don’t deal with Carmax and I said well they said the car is covered under warranty to go ahead and bring it into you guys and they will take care of the bill. They made a big fuss about it saying that it needed to go to Carmax then Carmax needed to bring them the vehicle even though I had all of my stuff located in the vehicle for traveling then they proceeded to tell me that they would not give me a loaner car during the time of my service. The Carmax representative that I spoke with in service his name was Al when I had addressed all of my concerns he had mentioned due to the tire issue. They would be replacing all four tires and that they would address the issues with the Start stop control the computer reacting and then disappearing, and also a safety recall that I had noticed about the airbags because the passenger side airbag kept displaying a blinking needless to say, after being totally inconvenienced, they have my vehicle for over a week. The second I went to pick up the car. I had to pick it up in the afternoon due to having to work in the evening they had it ready in the express. There was multiple damages to the vehicle, physical eng tire
