Just a stock dealership phrase "Its YOUR fault". You actually USED the jeep like in the brochure. Silly you.
I have said elsewhere the dealer will avoid warranty work almost to the extreme. The dealerships appear to train the reps to find any excuse to assign the failure to misuse by the customer.
I go through this every time I take mine in for warranty work (which will be less now I hope). Oh, you have a supercharger! That is why the radio flashes and the engine dies and the right turn signal won't turn off and I wouldn't be surprised if you overtorqued your frame and thats why the top leaks. I just say fine, why don't you give me a written explanation of why you think that is the cause and I'll take your explanation and all the posts I can find on the various forums from people who DON'T have modified vehicles, who are complaining about the same thing, to the arbitrator and we'll let the arbitrator decide. Hey! Sometimes that even works.
What can work is: "I can always take my vehicle elsewhere for servicing. You look up my records and see how much work I've had done over the years here and I think I can get the work done as good as and much cheaper than I can here." I don't have to resort to that (only once) or the above (only once) because my dealer's service department does have my records and can see how much money I have spent there.
You might try a few searches on the jeep forums (even the forum that must not be named) and take a list of people having the same issue with you. I did that on my transmission issue and they shut up about the supercharger.
