My car starts fine at the beginning of the day but once it's driven and parked, it may or may not start on the first or first few attempts. Sometimes it takes six or even seven tries before it kicks over. I think it turned off only once while driving (ever) and that WAS fairly recently but only once. One mechanic told me to only get the crankshaft sensor from Mercedes otherwise he wouldn't guarantee his work (which makes total sense) but I see the same part for as low as $15 from reputable online shops, whereas the part is $221 from the MB dealer.
I have the same problem. My car stalls for no apparent reason. Sometimes it happens often (more than once per day, sometimes it may go weeks before a stall. Usually after it stalls if I wait approx. 10-15 mins the car will start right up and I can drive away like it never happened.
