How reliable is the Kia Rio? What NHTSA's records show
We don't give the Rio a reliability score. NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models. Here is what's on file for model years 2010 on.

Every model year compared
Complaints rise with how many were sold and how long they've been on the road, so a newer or rarer year will show fewer. Compare years of the Rio with each other.

Safety recalls
5 recalls cover at least one Rio model year. Each covers a range of VINs, not every car. Check one car at nhtsa.gov/recalls.
The Hydraulic Electronic Control Unit (HECU) may experience an electrical short, which can result in an engine compartment fire while parked or driving.
The trunk latch base may crack, preventing the opening of the trunk from the inside.
A bolt in the steering column may not be secured properly, which can cause the steering column to detach from the steering rack and result in a loss of steering control.
The brake master cylinder may have been manufactured with sharp edges that can damage the inner oil seal, resulting in reduced braking performance.
The trunk latch may become damaged, preventing the opening of the trunk from the inside.

Was the work actually done on the car you're looking at?
Model-year records can't tell you about one car. A Kia service history check returns that vehicle's own dealer records by VIN.
Check a Kia's service historyCommon questions
Is the Kia Rio reliable?
We don't score reliability: NHTSA publishes complaint counts but no sales figures, so complaints can't be turned into a rate or compared between models. What's on file for model years 2010 on: 584 owner complaints, 8 warranty extensions and 6 service campaigns Kia filed, and 5 safety recalls. The model years with the most complaints are 2013 (153), 2016 (77), 2012 (54). Whether a known problem was fixed on one car is what its service records show.
What are the most common problems with the Kia Rio?
Across every model year since 2010, owners' complaints to NHTSA most often name engine (37%), other or unspecified (16%), airbags (15%). Kia has filed 8 warranty extensions covering the Rio, listed on this page.
Which Rio model years have the most complaints?
2013 (153), 2016 (77), 2012 (54). Complaint counts rise with how many were sold and how long they've been on the road, so compare years of the Rio with each other rather than with other models.
Has Kia extended the warranty on the Rio?
Yes: airbags (model years 2012–2013); airbags (model years 2012–2013); equipment and accessories (model years 2012–2013), and 5 more. A dealer does a covered repair for free within the extended time or mileage.
How do I check recalls on a Rio?
Enter the car's 17-character VIN at nhtsa.gov/recalls. That answers for one vehicle; the 5 recalls listed here are for the model, and each covers only part of it.
