When Problems Appear on the 2025 Kia K4
Based on 11 owner complaints that included an odometer reading. Median mileage at time of complaint: 1K miles. Most complaints cluster in the 0-30K miles range.
Mileage figures are self-reported by owners in NHTSA complaint filings. Peak bucket = the mileage range with the most complaints for that component; it reflects when owners noticed and reported problems, not necessarily when the fault first occurred. This vehicle is under 5 years old, so most of the fleet hasn't accumulated high mileage yet — low-mileage peaks reflect fleet age, not necessarily premature failure.
