The crank position sensor was replaced after the car stopped. Another member made a post previously describing the exact situation I had so I wont re-hash it here. The car's been very reliable, so this is the first issue with it period. It was taken to a chrysler dealer which is looking more like a mistake each day. The Crank Pos. Sensor was replaced & as I got on the highway to head home I engaged the cruise control ( above 55mph) & there was no response from the car. The cruise works at 55mph & below. It was taken back to the dealer & they say the the repair they made has nothing to do with the "new" problem; they're not responsible for it. I've gone through the threads & found that this is no isolated problem that no other x-fire owner has seen, & in those other cases the problem stood alone, so what are the odds that this cruise control problem coincidentally hit immediately after another repair was done.
