I was driving my car was sputtering or trying to shut off while I press the gas and I let go of the gas and it catches and stayed on. I took it to the dealership and they said they found nothing wrong. May 3rd around 12pm im driving on the freeway and as im getting on the express lane going 60 it dies and I couldn't move the steering wheel and I slammed into a guardrail. After doing research my car (vin [XXX] ) had multiple recals from the fuel pump and steering wheel and the dealership never fixed or checked any recalls before selling it to me.

According to the Mercedes-Benz class action lawsuit, fuel can leak into the engine compartment from fuel line connections to the fuel pump at the rear of the engine compartment. Mercedes C300 and other C-Class vehicle occupants complain of strong fuel smells caused by the fuel leaks. Please assist
Due to the type of fuel line and clamps used to fasten them, cold weather has caused them to shrink such that gas leaks, which comes through the car vents into the car cab and now into my [XXX] and [XXX] kids's lungs. Mercedes has issued a 10 year warranty on this specific feature, but it should be a safety recall unless we agree that inhaling gas vapors is okay for your health.

Very strong gas smell inside the car when started and heat or air is turned on. I have done research and it is a common issue with this car. This is a very serious issue that can cause an engine fire with the gas leaking in the engine compartment.
I got my oil changed last week and not my car has the check engine light on and is throwing the code p025e. From what I’ve read this is common problem in these cars. It’s an environmental hazard, because when this happens the car is not dispelling the fumes as it should and cannot be ventilated correctly.
My 2015 Mercedes Benz vehicle is rarely driven as I took public transportation to work and has ~55000 miles. However, the engine has started throwing error code P052E verified by an independent dealer - crankcase ventilation valve failure. It means the engine could shut off amid driving and I did research and it seems like a very common issue that Mercedes Benz car owner encounter and feels like a severe car defect.
I have a fuel smell in the cabin of my car which started about 3 weeks ago. I have drove the car a couple of times and it was pretty bad, also my sunroof almost blew off the car while driving to dry the car after removing the salt from the streets after the snow. I have since parked it in the garage to avoid any further damage. I will submit pictures so you can see the sunroof.
