My Fiat 500e has a battery warranty for 10 years. I had my vehicle towed to Chrysler/fiat service center in Newton NC. They had it over a month and said they ran many diagnosis. For each diagnosis they had to contact The mother company and ask what to do and then wait many days for a response. Meanwhile I had no vehicle. In the end they said I needed a new PIM (power inverter module) to the tune of 8k. They would not guarantee that would actually fix the problem but said I had to pay that to find out if that would fix the HV (high voltage battery that's guaranteed). I seen posts from other 500e owners who were in the same predicament. I'm not going to spend 8k on something they don't guarantee the diagnosis was correct. They're charging me about $500. For the diagnosis fee before I can get my car release. My car still sits at the dealer. It seems Chrysler would have to guarantee their diagnosis is correct. I asked for a detailed invoice showing exactly which diagnosis test were performed as well as a circuit diagram. They said they don't give that information out to clients. Don't I have the right to know what I'm paying for? This has been very difficult on me to say the least.
