that's what pisses me off, FIAT didn't even offer a buy back. They just keep rejecting the case without much explanation and there's no one I can talk to. I might visit the Arlington dealership as it seems like they're more successful in dealing with FiatI took mine to the dealer in Arlington TX for an A/C issue (leaky compressor). One of the service people told me that Fiat really doesn't want to honor their battery warranties on these cars. He said it takes four to six months of bitching at Fiat before they will finally do something. He showed me several cars on the lot that they had bought back, most for much more than the customers paid for their cars. Clearly that is the cheaper way out for Fiat. He also said, that they had replaced several batteries on cars whose owners refused several buy back offers as they wanted their cars fixed. I don't know but, perhaps you'd have better luck with that dealer as they've successfully gotten Fiat to honor their warranties for their customers in the past.
Saying you did something wrong sounds like nonsense. I would ask what evidence they had that you didn't care for you car according to the owners manual. Good luck man.
