“I own a Mercedes-Benz E500 bought new in 2004. 3 days ago I was driving the vehicle at about 35 miles an hour and car stalled and came to an abrupt stop in the middle of the road with no warning. I could not start the engine back for about 5 minutes. Luckily there were no other vehicles behind me, which would have hit me from behind. I later towed the car to the mercedes service station. They reported it as an electircal failure due to failing of the crankshaft position sensor. They have replaced the faulty sensor and the car is running ok now. …”

Have brought the car into dealership 3x for the issue, and they claim they cannot duplicate the problem, and claim there is nothing wrong. It has been happening for the last 10k miles. …”
