I had a 2012 500 for a short period of time - ~60k miles/4 years old and ~1 month before my emissions check was due an EVAP leak popped up. Gas cap replaced - still EVAP leak, smoke test no dice, finally the horrific Fiat/Chrysler dealership just proposed replacing the gas tank and all the lines to the tune of $800-$900 but could not guarantee that would fix the issue. Traded it in 2 days later.
Honestly it was a very fun car but the horrific dealer service and to have an issue of that magnitude at such an early age/mileage was a huge turnoff. I was burned by Chrysler previously with a 1999 Neon that was pretty much junk by 85k miles and needed more repair work than it was worth (yeah I know entirely different company like 3-4 owners ago) but after the Fiat experience it was enough to make me never want to get near a Chrysler or FCA car ever again.
