At the shop, Kia fuel-system issues have a recognizable signature. 213 documented complaints across 35 year-model entries from 2005 to 2023 is consistent with what we see come in. Complaint volume is spread across the lineup rather than parked on one bad year. That's the signature of a platform or supplier issue, not a single-year flub. 11 fire reports on the federal record — not common in this category but documented and worth weight. Across the 69 complaints reporting odometer mileage, the median failure lands at about 85,163 miles. Average shop fix runs about $1,200 — not catastrophic, but it adds up over time. Check the fuel pump access cover for prior work. A vehicle on this list that already had a pump replacement is a vehicle to consider — the work is done.
