I know I'm late to the party but had to post this. My car started shutting off for no apparent reason last week (I have a gunmetal 2004 Crossfire Ltd. btw). Then it died on me on the weekend while entering an on ramp. I had traffic backed up for almost an hour until a tow-truck came. The long and the short is that after bringing it to the Chrysler stealership, they said my car was 2.5 liters short of oil. Impossible since I had recently changed the oil and had no leaks (first flag). My car wasn't burning oil either. They then said the oil was black. This was before I told them I recently had an oil change. Then I asked if it might be the Relay Control Module. The mechanic said he had never heard of that before (second flag). I called my own mechanic who usually works on the car and he spoke to Chrysler. The Chrysler mechanic changed their tune in a hurry. I told them not to touch the car and I`d get it to my own mechanic. Before leaving, I asked what it would cost out of curiosity to fix the issue. They said, it`s most likely the pcv valve. It would cost roughly $400 plus labor. I said I`d pass. After checking this forum, everyone said it`s gotta be the `crankshaft position sensor`. I had my mechanic order me one. It cost me $135 Canadian from the Mercedes dealership with same day delivery and $60 to put it in. I was in and out of my mechanics in 15 minutes. Just to be safe, he checked my oil. Turns out my oil was fine. I was about half a liter short (Chrysler charged me $135 just to check my car out and didn`t even tap up my oil as they said they would) and he said the oil may have gotten some fuel in it but otherwise it was fine. Had it not been for all the help on this forum, I would have been taken to the cleaners. Thank you to everyone who took the time to put up tutorials and give their opinions in regards to this issue. God and the internet are a blessing!
