How it compares in its class

Percentile ranks against other compact cars in the catalog.

Reliability: better than 38% of compact cars
Longevity: better than 63% of compact cars
Running costs: better than 73% of compact cars
Value retention: better than 91% of compact cars

Which of these numbers are measured

What stands behind each score for this car:

Reliability 82: from NHTSA recalls and complaints. This one is a raw count: we do not have a sales figure for this model, so a high-volume car looks worse here than it should.
Longevity 80: an estimate from powertrain and brand record. No 200,000-mile population exists for a 2015 car yet, so this is a prior, not evidence.
Maintenance 87: repair-cost data where we have it for this model, otherwise a mechanical-complexity estimate from engine size, cylinder count and drivetrain.
Safety 80: NHTSA crash testing blended with IIHS awards.

Common questions

What goes wrong with the 2015 Kia Rio?

Owners have filed 52 complaints with NHTSA for this model-year, and engine is the most reported area with 17 of them (33%). There is 1 recall on record. Check any specific car against its VIN before buying.

Is the 2015 Kia Rio reliable?

AVOIR scores its reliability 82/100 (excellent) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.

How long will a 2015 Kia Rio last?

AVOIR scores its longevity 80/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2015 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
