Check engine light with error code P052E. From my research, this is a very common issue with this engine and one that either has been recalled or is planning to be recalled. According to some online forums for Mercedes Benz, Mercedes is being sued over this problem and has issued an extended warranty on certain models because of how common this problem has become. The list of models needs to be expanded to include other models experiencing the same problem.

Inside the car smells gas either idle or running. Dashboard lights flactuate and sometimes the gas gage doesn't show how much fuel you have left. Command system shuts off after 3 mins even the engine is on. But mainly, the gas smell in the car. Have trouble breathing at times and I don't haveany underlying condition.

While merging onto the freeway on 1/22/2021 the car's dashboard displayed "collision prevention assist plus inoperative " and the check engine light come on. When this happened, it prevented me from accelerating the car by pushing onto the gas pedal. This caused the car from behind to almost rear ended by car. I was able to drive onto the shoulder of the freeway and exit the freeway. I have taken this car to the Mercedes dealership for repair but it is an ongoing issue even after various parts have been replaced.

My car has shut off on me while driving two times and road side assistance came out two different occasion. I kept up with maintenace on the vehicle. I went to pep boys up the St from my house instead of Mercedes for oil changes. Out of no where my engine light came on and I towed my car two Mercedes to fix. They said my engine blew N the turbo. They won't cover it under warranty since I gave them all my maintence receipts from pep boys. This was a demo car I originally leased and had it for 2 years with 9 months left on the car. The recalls on the VIN were not fixed and Mercedes is trying to send me away with a unfixed car. Please help
