Call the Dodge customer service line. If it is a common enough problem, they will either fix it for free or pro-rate it.
If they deny the problem, printout the investigation and take it to the dealer, hopefully that will be enough information for them to repair the problem.
The dealer probably doesn't know what the problem is and just replacing one thing at a time until fixed, unfortunately you are stuck waiting for them to fix it. They have resources available (factory tech's that can help them over the phone, or even travel to the vehicle). They just prefer not to have to use them.
