The 2002 Kia Optima has no open NHTSA recalls. Owners report 7 recurring issue clusters, led by “Front subframe corrosion and control arm separation.” 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.

Critical for safety and preventing major damage
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.
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

Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect brake pads and rotors every 7,500 miles. Forte and Soul front pads typically last 40,000-55,000 miles.
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.
Replace DOT 3 brake fluid every 30,000 miles or 24 months. Required for ABS and ESC pump longevity.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Replace engine air filter every 30,000 miles. Severe or dusty conditions: 15,000 miles.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95

Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Iridium-tipped plugs rated 105,000 miles on most Kia engines. 1.6T (Forte GT, Soul Turbo): 60,000 miles. 3.5L Lambda II V6 (Telluride, Sorento): 105,000 miles.

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
Kia Long-Life Coolant (pink, same as Hyundai): first change at 60,000 miles, then every 30,000. Do not mix with green or orange coolant.
Estimated cost — typical U.S. ranges

Occupant deaths in fatal crashes (FARS)
49 crashes 1990–2024
How the 49 occupant deaths break down
42
driver deaths
7
passenger deaths
49
occupant deaths
Crash years covered: 1990–2024 This model year first appears in 2002 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.
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.
