Common problems with the 2008 Rio

NHTSA's file holds 46 owner complaints on the 2008 Kia Rio. Owners named the airbags most often: 27 complaints, and half of the 23 that list a mileage came after 64,000 miles. A complaint can name more than one component.

Of the 46 complaints, 11 report a crash, none reports a fire and 7 report an injury (10 people reported injured). These are owners' reports to NHTSA, not findings.

Mileage when owners reported a problem with the 2008 Rio

The 39 mileages owners gave run from 48 to 196,000 miles. A quarter are at or under 6,500 miles, half at or under 46,000, three quarters at or under 90,000 and nine in ten at or under 110,125; 7 (18%) came after 100,000 miles, 1 (3%) after 150,000 and none after 200,000.

These mileages say when owners reported a problem, not when a 2008 Rio wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.

Most of these reports came early in the vehicle's life: 32 of the 39 came at or under 100,000 miles, so they say nothing about how many miles a 2008 Rio can cover.

Is the 2008 Rio a good year?

Complaint counts cannot say whether the 2008 is a good or a bad Rio: they rise with how many were sold and how long they have been on the road. They show how the 2008 compares with the other model years in NHTSA's file.

With 46 complaints, the 2008 ranks 10th of the 23 Kia Rio model years from 2001 to 2023 with 10 or more complaints, counting from the most, tied with 2007. The most: the 2001 (223). The fewest: the 2022 and 2023 (12 each).

Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.

What these figures can and cannot tell you

  • Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
  • The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
  • The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
  • They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2008 Rio lasts.
  • A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2008 Rio.
  • Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
  • 7 of the 46 complaints on the 2008 Kia Rio give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
  • NHTSA name counted: RIO. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
  • Recall-file name matched: RIO.
