I actually called them and asked them about it. They don't care about extended warranties. They said they make everyone sign for a $91 "check out fee" which is not covered by the warranty or deductable. I'll bet when the salesman sold you the warranty he said you would never be out more than $100 for a repair.

I also called my local dealer and while they also have the diagnostic fee of $90 they apply it to the repair so you still only pay the deductable. He told me no chrysler dealer would make you pay that fee and the deductable and I told him Westborn Chrysler does and it is cuasing an internet storm. He said someone needs to contact Chyrsler about this and felt that charging on top of the deductable was dishonest if not ilegal.

Here is place to get even with them:
