2010 Kia Optima — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 99 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Powertrain (transmission & drivetrain)24 (24.2%)Official recall records for this system: 4, covering model years 2006–2018.
• Air bags (restraint system)17 (17.2%)Official recall records for this system: 7, covering model years 2001–2016.
• Electrical system13 (13.1%)Official recall records for this system: 2, covering model years 2001–2016.
• Engine10 (10.1%)Official recall records for this system: 15, covering model years 2011–2020.
• Speed control & accelerator6 (6.1%)
• Brakes4 (4.0%)Official recall records for this system: 9, covering model years 2011–2019.

Other / uncategorized: 4 classifications (4.0%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.

These are counts of records held by CarFaultIQ, not a failure rate. More records can simply mean more vehicles were sold or more owners reported. No vehicles-in-service figure exists in this data, so no reliability or risk score can be derived from it.

What the records are about, by source

Each source is kept separate: owner complaints, recalls, manufacturer communications and investigations are different kinds of record and are never added together. All model years.

• Owner complaints (14,972 records, model years 2001–2020) are most frequently classified under: engine, electrical system and steering.
• Transport Canada recalls (68 records, model years 2011–2020) are most frequently classified under: engine, brakes and fuel system.
• Manufacturer communications (2,894 records, model years 2001–2020) are most frequently classified under: engine, electrical system and equipment & accessories.
• Investigations (73 records, model years 2001–2020) are most frequently classified under: engine, lights and engine cooling.

"Most frequently classified under" reports how the records are filed by the source. It is not a finding about causes, and a record can be filed under more than one system. Read the individual records

Mileage reported when the issue occurred

• 61reports included a mileage
• 65,100average of those mileages

This is the mileage owners recorded at the time they reported, not an expected failure mileage and not a prediction for any individual vehicle. The lowest and highest figures on record are not shown: they are unverified odometer entries that include zeros and implausibly high readings, so they would not describe a real range. A median is not shown either, because the stored figures are group totals and a median cannot be recovered from them.

Counts are not adjusted for how many vehicles were sold in each year, so a taller year is not necessarily a worse year.
