Kia Rio: Years to Avoid and Best Years (Engine & Transmission)
Kia Rio problems by model year, from 583 owner complaints filed with NHTSA. For each year: the share of complaints about the engine, transmission or fuel system, how many there were, and the recalls.
Worst years to avoid: 2014 (67%, 30 drivetrain complaints), 2018 (67%, 16 drivetrain complaints) and 2012 (64%, 29 drivetrain complaints). 9 of the 9 Kia Rio years we score have an elevated engine, transmission or fuel-system complaint share; 4 of them are at the very high level (60% or more), where every model year we track has a documented failure behind it.
No Kia Rio year we score is clear of an elevated signal. The lowest is the 2017 (43%).
By raw volume, the 2013 drew the most drivetrain complaints (61 of 236 across the scored years). Volume also tracks how many were sold and how long they have been on the road, which is why the share, not the count, sets the verdict.
2021, 2022 and 2023 have fewer than 25 complaints on record so far, too few to score. Newer cars have had less time to collect complaints.
Engine and transmission complaint share, 2010–2023
