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. I don't know what could have happened if I didn't service the vehicle, but any engine issue is dangerous while a vehicle is in motion.

  • 36,000 miles
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. Peoples lives have been lost due to this issue. One lady was hit by a train when this same situation occurred and lost her life. I am very concerned for my safety and of my grandkids whom I Transport in this car. It also seems that something is wrong with the gears. Sometimes, I put it in reverse and it sits there. I put it in drive and it will not move. I feel very unsafe in this vehicle. Please help.

Car started to vibrate at idle then graduated to shaking at all times even during acceleration. Acceleration very slow, stuck feeling. Brought to Mercedes at 28K miles. They stated it is a cracked piston in cylinder 1. this is apparently a very common issue with this engine but there are no recalls yet.
