update: I just got off the phone with Chrysler's Warranty department. Told the guy my story and he seemed as confused as i was. So he puts me on hold and calls the dealership. 5 - 10 minutes later he comes back and says this is what happened. The sensor was faulty (duh...we already knew this as did the mechanic because I told him so) but he had to check some wiring harness and that turned out to be ok so because it is fine they would have to charge me the fee. At this point im steaming (did I mention i'm in Anchorage for work so im already 4 hours behind nothing like getting up at 5am to talk with a mechanic who is in 9am time). I ask the rep on the phone straight up, wiring harnesses are covered under my plan, I had a real issue, warranty work is being done...why am I being forced to pay this fee. His answer "because the harness was ok. it was not broken, they can charge you the fee". So i ask then, "so every time i bring the vehicle in they will probably go ahead and "test" something that is fine just to get the fee out of me." no answer for a good 30 seconds. He than tells me to mail the bill into their corporate office and they will review the case. Long story short. Im out of town, car is in the shop, and I'm being billed $190 for a $150 part that is covered under a warranty with a $100 deductible.
