Every Kia Rio model year

Pass rates fall as cars age, so the only fair comparison for a 2021 car is other cars of the same age. The full run for the Kia Rio:

What this means if you are buying a 2021 Rio

The 2021 is one of the stronger years for this model, passing 19.7 points more often than the Kia Rio average. That is a point in its favour, though condition and service history still matter more than the model year.

What a 5-year-old car fails on

A 2021 car is 5 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 low mileage, which usually means light urban use. Short journeys are harder on batteries, brakes and exhausts than motorway miles, so do not assume low miles means low wear. On a 2021 Kia Rio the average at test was 21,618 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.

2021 is the strongest year on record for this model at 94.4%, ahead of every other year we hold data for.
