Every number on this page comes from real pre-purchase inspections — cars people were about to buy and paid an independent inspector to go through point by point, engine to underbody, paint depth to error codes. Not owner surveys, not warranty statistics, not forum lore: what we actually found.

How long does a Kia last?
Across every Kia body style we've inspected — sedans, SUVs and anything else pooled together — the average one's condition dips below decent (a 55/100 score) around ~122k miles. It ranks Kia #9 of 24 brands we have enough data to rate; the longest-lasting, Tesla, holds up to ~182k. Shopping a Kia near that mileage? Expect more wear ahead — see which makes give the best odds at your budget.
Good cars by mileage
Good cars by age
Share of Kias in good shape (scoring 60+/100) by mileage and by age when we inspected them (each dot ≥5 cars; a band under 20 cars follows the nearby bands, so a run above the all-cars line stays above it, and a band of 20 or more uses the rate we measured; where a band has too few cars, the line follows the trend between the bands on either side; rolled-back odometers excluded from the mileage curve). The dashed grey curve is all cars we check.

The bottom line
The story on these cars is an engine problem, not a bent-frame problem. Oil leaks, fuel trim, and cooling faults lead the list, so a tidy body and rare structural repair should not talk you into a bad powertrain. Check for oil seepage, out-of-range fuel trim, and low coolant before you spend time on tires or warning lights. Repaint is ordinary here, so do not walk for paint alone. Condition tends to slip below decent around 122,000 miles, a better mileage window than most brands in this set; past that point, any oil leak paired with a fuel-trim or coolant fault is a reason to negotiate hard or leave.
