“When idling at the light. The car would shut itself off. All the warning lights will come on. I then have to restart the car with the push start to reset it. Then it'll work fine. I have been to mercedes dealership in new rochelle for four times about this issue. They changed the battery the first time. Two days later the situation occurred again. Then the second and third time they gave me back the car and said they didn't see anything wrong because no codes popped up. Both times I took the car back and the situation occurred again. …”

“When the car is in the a feature, where it turns on and off when not in motion, it gets stuck in that mode as if a magnet is holding it in that position. It will not move, it stalls. I turn it off and turn it back on and sometimes it still will not move, sometimes, it will not turn back on. This has happened on several different occasions. Once, I pulled to the side of my mailbox to pick up mail, and another occasion I pulled into my garage, and it stopped, and would not turn on. This is very dangerous, I would hate to be in traffic, railway crossing, ir stop sign and this occurred. …”

“My car threw the check engine code P052E, the issue is the positive crankcase ventilation valve being faulty. Incredibly common on this model and now failed on my car too at 60K miles. All maintenance was done up to this point with the dealer and at or before recommended intervals.”

“My car leaked oil very fast while me & my wife were on a trip and it stopped on the highway and engine was stalling and misfiring due to a manufacture defect that is common with this model so it did put us in a very dangerous & risky situation. Now after i paid $1,740 the dealer is saying that my car needs a new engine due to cracked piston in cylinder 1 that damaged the engine which is a common problem with this model around the 50k miles.”

“At approximately 26,500 miles of use, the check engine light came on in my Mercedes Benz C300. I brought the vehicle to the dealership and they informed me that the diagnosis was a crankcase vent valve malfunction. The MB fault code is P52E71. After paying Mercedes to fix the issue, I found forums on the internet where many other MB owners reported the same issue at around the same mileage. Being that this seems to be a common malfunction with the C300, I believe that it should be considered as a recall issue. …”
