Kia K5 problems, by model year and system
496 complaints owners filed with NHTSA about the Kia K5 2021–2027, and the 1 system the record is deep on — fuel system (157). Each system has a page across the years; 2 model-year pages go deeper still. Every figure is a linked federal record; none is a failure rate or a verdict on one car.

Complaints owners filed with NHTSA naming each system, per model year; a bold count links the year’s own page on that system. Counts scale with sales and with time on the road; nothing here is a rate, and NHTSA’s headings are coarse (“Power Train” is the transmission and the driveline).

Fuel system: 157 complaints across 7 model years, 32% of everything owners filed about the Kia K5. A count, not a rate — it says nothing about how many were sold.
Which Kia K5 year has the most complaints?
2021 (167), 2022 (128), 2023 (107). Older years have had longer to collect them; the year pages show each year's share by system.
