Kia Rio years to avoid
Across the 2015–2016 Kia Rio, no model year reaches 1.6× the median of the other years with enough owner complaints at NHTSA to compare; the 2016 came closest, at 77 against a 52 median of the rest, with 52 at the other end. NHTSA holds fewer than 40 complaints for 2017, 2018, 2019, 2020, 2021 and 2022, too few to read as a quiet year rather than a gap in the records. Separately, the 2016, 2017 and 2021 each carry the most recall campaigns, 2. Complaint volume and recall campaign counts also reflect how long a model year has been on the road and how many were sold, so they rank years within this model rather than measuring build quality.
No model year of the 2015–2016 Kia Rio stands clear of the others on owner complaints.
Every Rio model year, ranked
Every Rio model year NHTSA holds records for, most complaints first. Counts are NHTSA records as of 2026-09-15; recall campaigns and complaints are counted separately because a recall is the manufacturer acting and a complaint is an owner reporting. Years with enough on record have a page of their own.

Buying a Kia Rio? Check its VIN.
Model-year complaint totals do not describe one car. Confirm its identity free, then decide whether to review its reported title, mileage and auction history before you buy.

- A higher count is not proof of a worse car. Complaint volume rises with sales volume and with years on the road.
- The comparison is between years of the Rio only. It says nothing about how the Rio compares with other models.
- NHTSA publishes owner reports without verifying them. A complaint is an allegation, not a defect finding.
- Recall campaigns cover production ranges. Only a VIN lookup shows whether one vehicle is included and whether the work was done.

Kia Rio year-by-year questions
Which Kia Rio year should I avoid?
Across the 2015–2016 Kia Rio, no model year reaches 1.6× the median of the other years with enough owner complaints at NHTSA to compare; the 2016 came closest, at 77 against a 52 median of the rest, with 52 at the other end. NHTSA holds fewer than 40 complaints for 2017, 2018, 2019, 2020, 2021 and 2022, too few to read as a quiet year rather than a gap in the records. Separately, the 2016, 2017 and 2021 each carry the most recall campaigns, 2. Complaint volume and recall campaign counts also reflect how long a model year has been on the road and how many were sold, so they rank years within this model rather than measuring build quality.
Which Kia Rio year is the safest bet?
No model year of the 2015–2016 Kia Rio has enough owner complaints on record to call it the quietest. Choose on condition and service history rather than model year, and check the individual VIN.
Do complaint counts mean the Kia Rio is unreliable?
No. NHTSA complaints are unverified owner reports, and the count rises with how many vehicles were sold and how long they have been on the road. They are useful for comparing years of the same model — which is what this page does — not for ranking one model against another.
How do I check a specific Rio?
Take the 17-character VIN from the windshield or driver-door label and run it through NHTSA's free recall lookup. That reports open campaigns for that exact vehicle, including whether the repair is still outstanding. A model-year page cannot tell you that.
