    The car wont start, and you have to wait for a while and try again before it starts. When I took it to the dealership, they could not replicate it. It also only happens when the weather is cold

    2003, C240, 1 owner, car stalls, cools down and restarts and runs for about 15 minutes, then stalls. Replaced fuel filter and fuel pump; problem persists! Also, checked battery and alternator (both were o k) after 1'st stall episode. Will look for crankshaft position sensor and replace if possible.

    Sitting at a light, started to go and car died. Red "Battery/Alternator Visit Workshop" death message appeared. Restarted car and continued on. Took to the shop after work, hooked up to computer for codes, crankshaft sensor hanging on by a thread. Replacement at $249.00. Glad it happened now, driving nearly 1,100 miles next week for OBX vacation!

    Check engine light came on. Took it to the dealership. they said it had mis-fired. and that there was an oil leak that was not such a big deal except that it is leaking onto the Crank sensor!! They reset everything and cleaned everything off, and told me to bring it back WHEN it happens again. Ive only had this car for a month! I wish ihad read this before i bought this car!

    Parked the car in front of our building after driving it briefly (engine was warm). After about a 10 minute stop, tried restarting the car. Engine would crank (turnover) but would not start. Tried three times. Paused for a minute and tried fourth time, and engine finally started with the Check Engine light illuminated. Was not able to take to repair shop until a week after -- we drove the car a few hundred (!!) miles in between without incident. Repair shop scanned computer and told us the Crankshaft Position Sensor was faulty. Replaced the CPSO, part was $100, labor was $115 (one hour), total of $215 plus tax.
