Same problem as others. Car would start and drive fine until I shut it off after a long drive. Would not immediately start back up until engine cooled. Paid just under $300 for Crankshaft sensor replacement at shop and problem went away. It was interesting that I found the part at many locations for less than $60... Wish I had time to try to F.I.M. sheesh! Definitely seems like a cheap easy fix if you have the time and the tools.

Car would suddenly die with little/no warning. Usually after running for a bit when it got fairly hot out. Once dead no matter how long you crank no start. Wait 15 mins till cool and it would crank right up and be fine. Replaced the Crankshaft Position Sensor Failure and all symptoms went away. Fairly easy DIY project.

Car would not start after if it was shut off for a only a few minutes and stalled once in traffic. Replaced the camshaft position sensor once a year ago and now it seems I need to replace it again. As stated, I had a problem with the car not starting after it had been running and only sat for a few minutes. Now having the problem again, except the engine cut off suddenly in traffic. Starting to think this is a common problem and needs to be addressed by Mercedes. It is an easy fix, but it is not a cheap part.

Vehicle did not start and after a few minutes it started again. It later had the same problem and I took it in to the dealership for resolution. The problem was the Crankshaft Sensor.
