“Re: c 240 mercedes 2004. The car will suddenly cut off while driving. This has happened on long drives on the interstate, short drives on the interstate, and street driving. The mechanic cannot find any codes associated with this defect. We had the crank sensor changed because the mechanic thought that a worn crank sensor might be the cause. It was not. Two days later the car 's engine shut down again.”
