Just bought 04 JGC with 105,000 miles. One week later it stalls while I'm driving. Had it towed to dealership that replaced the coil pack on 2/29/12 to be told the problem is the power train control modual and it will cost $971.50 to fix it. Can anyone tell me if they have had this problem and did this power train control modual fix the problem? I don't have the money for guessing games. I will mention that once the tow truck driver arrived it started fine but I had it towed any way and the dealership hasn't been able to duplicate the issue but I know it happened and I feel very very very unsafe.
