Before you let ANY dealership work on your SRT6 (or Crossfire), ask them if they have any Crossfire certified techs at the service center. If not, run, do not walk, to a new dealership. Otherwise they will guess their way to a solution as they apparently tried several times, and failed. Check this board often as there is some REALLY good info that would have saved you time and the dealership time and money. Lots of known problems and fixes are here. (Make sure the E19 fan control module recall was done on that VIN while they are hacking away at the 2ndary IC water pump).

If you have the extended warranty where they give you a rental while they hack your SRT6 up into small pieces, take advantage of the free rental. If not, suggest getting a gratis rental if they can't diagnose the problems correctly and get it back to you in a timely fashion (which shows they don't have the needed expertise on site).
