2007 Kia Optima Recalls, Problems & Maintenance

The 2007 Kia Optima has no open NHTSA recalls. Owners report 6 recurring issue clusters, led by “Dim low-beam headlight output.” Kia uses Hyundai Motor Group's powertrains, so service intervals mirror Hyundai's. Kia Promise covers the first 3 years / 36,000 miles of complimentary maintenance. Kia owners with the Theta II 2.0L/2.4L (Optima, Sorento, Sportage 2011-2019) should adhere strictly to oil intervals due to known oil-consumption issues in Kia TSBs.

No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter

Every 3,750 mi

Severe service: every 3,750 miles. Normal: 7,500 miles. Theta II 2.0L/2.4L on Optima, Sorento, Sportage (2011-2019): full synthetic only, never extend.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 7,500 mi

Rotate tires every 7,500 miles. Telluride and Sorento AWD owners benefit from rotation every 5,000 miles to prevent uneven wear.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 7,500 mi

Estimated cost — typical U.S. ranges

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Fatal crash history & reported problems

Occupant deaths in fatal crashes (FARS)

78 crashes 1990–2024

How the 78 occupant deaths break down

52

driver deaths

26

passenger deaths

78

occupant deaths

Crash years covered: 1990–2024 This model year first appears in 2007 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number

FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.

Why we show driver deaths too

Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.

Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.

IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.

Owner-reported problem signals

Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
