Shouldn't that still be covered under the battery warranty?

Related: The problem I have with Fiat is that there's an obvious step to combat the impression of poor reliability/durability: Increase the standard warranty. If Fiat declines to increase the standard warranty, the impression is even worse — it's that they're not increasing the warranty because it isn't financially viable for them to do so, because the reliability is bad and that Fiat can't afford to warranty the cars past 3 years. Compare to e.g. Hyundai with a 10-year/100k-mile powertrain and 5-year/60k-mile general in the USA.

Also related: I'm in Canada but looked up Hyundai's USA warranty there just to give more-broadly-applicable numbers. It seems that Fiat's warranty in the US is actually better than in Canada, where it just seems comically low — other than for the high-voltage battery the Fiat 500e new vehicle warranty is lesser of 3-years/37k miles.

Most cars are sold by the first owner between 30,000 and 60,000 miles. Hyundai's warranty is cut in half for the second owner, 5/50k powertrain and 2.5/30k general. There's nothing to cover, so it's basically free to put 10/100k in all of the commercials.
