THE CAR STALLED AT A TRAFFIC LIGHT AFTER 15-MINUTES DRIVE. STARTER TURNED THE ENGINE JUST FINE, BUT THE ENGINE WON'T START. AFTER ABOUT 20 MINUTES I WAS ABLE TO START THE CAR. NEXT DAY IT HAPPENED AGAIN - AFTER A DRIVE CAR WAS PARKED AT THE STORE PARKING LOT AND IT WON'T START ONCE I RETURNED TO IT 10 MINUTES. AFTER UNSUCCESSFUL ATTEMPTS TO START THE ENGINE FOR ABOUT 20 MINUTES, I WAS ABLE TO DO SO AGAIN. BOTH TIME THE "CHECK ENGINE" LIGHT WAS ILLUMINATED AND OBD CODE WAS "P0335 - CRANKSHAFT POSITION SENSOR A CIRCUIT MALFUNCTION". I'M DEEPLY CONCERNED WITH THIS SAFETY ISSUE, WHICH APPEARS TO BE QUITE COMMON FOR THE MERCEDES-BENZ CARS.
