Every Fiat 500x model year

Pass rates fall as cars age, so the only fair comparison for a 2018 car is other cars of the same age. The full run for the Fiat 500x:

What this means if you are buying a 2018 500x

The 2018 is one of the stronger years for this model, passing 6.5 points more often than the Fiat 500x average. That is a point in its favour, though condition and service history still matter more than the model year.

What an 8-year-old car fails on

A 2018 car is 8 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:

  • Lights and electrical: 10.36% of all cars tested
  • Suspension: 8.65% of all cars tested
  • Tyres: 6.23% of all cars tested
  • Brakes: 6.1% of all cars tested
  • Visibility: wipers, washers, glass: 4.65% of all cars tested
  • Body, chassis and structure: 3.18% of all cars tested

That is below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck. On a 2018 Fiat 500x the average at test was 40,458 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.

The strongest year for this model is 2021 at 91.8%, and the weakest in our data is 2015 at 74.3%. That 17.5 point spread across the model's life is why comparing a 2018 car against a newer one tells you very little.
