Kestrel Take

Twenty-nine complaints is a thin record, and a thin record is not a reliability rating — it means few owners have filed yet on a car that is barely two years old. What is on file is worth knowing: the fuel-tank check-valve recall that defines the 2021–2023 K5 covers this year too, the chrome rear-window trim recall is here, and among the nine engine complaints are two engines that let go with metal in the oil, one on the expressway. Those are single reports, not a pattern; we name them so you know what to look for on the dipstick. This is the last K5 before the 2025 refresh, so it is priced as the outgoing model, and most examples are still inside Kia's 5-year, 60,000-mile bumper-to-bumper warranty, which transfers to you. Buy it with both recalls closed, a flat rear seat, a clean dipstick and a stall-free drive, and lean on that warranty for the rest.

What we checked

Reconciled against public records, 2026-09-25

NHTSA holds 29 owner complaints for the 2024 Kia K5, and 2 recall campaigns.

A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 31% of them are about one thing — the engine. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.

2 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2024 Kia K5

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

Fuel tank can pressurise, swell and melt against the exhaust — check valve recall (recall)High — wallet impact

Recall 25V794 covers 2021–2024 K5s: a damaged check valve lets air into the fuel tank, the tank expands, and it can press on hot exhaust and melt, which can start a fire. On the 2024 the record holds a handful of these, but one is vivid: a pop from the back, fuel spitting out of the filler neck, and the gauge suddenly claiming an empty tank. The remedy is a new check valve and a tank inspection, with a new tank if it is damaged, free. Check the VIN on the NHTSA lookup, lift the rear seat cushion and compare the floor on both sides, and smell the filler area after the test drive.

Repair cost: $0 with the recall — verify it was performed; $1,500–$3,000 for a tank if you end up paying

Metal in the oil at low miles, loss of power on the highway, and hard, hesitant shifting — a scattered engine clusterMedium

Nine engine complaints and no single fault. Two are serious: an owner who found metal flakes on the dipstick and a filter full of shavings at 2,500 miles, and an engine that made a noise at expressway speed, lost power and poured oil across the road. Others are the transmission hesitating and jerking in low gears, phantom braking, and a car that a dealer could not diagnose without a special tool. With nine reports we cannot call any of it a pattern, but the dipstick check costs nothing: pull it cold, wipe it on a white paper towel and look for glitter. Ask a Kia dealer whether this VIN still carries the balance of the 5-year, 60,000-mile warranty — on a second owner the 10-year powertrain cover does not transfer.

Repair cost (estimate): $4,000–$8,000 for an engine outside warranty; $0 inside it — about 34% of what this car is typically worth

Chrome C-pillar trim beside the rear window comes loose and flies off on the highway (recall)Medium

Recall 25V493 covers 2023–2025 K5s: the trim pieces on either side of the rear glass can loosen and detach at speed, a road hazard for the car behind. Owners here had both pieces fall off, and one found the dealer had no parts in stock when they asked. The fix is a dealer inspection and new trim assemblies, free. One owner also asked Kia to extend an earlier trunk-lid trim campaign to this year; we cannot confirm that happened. Press each chrome piece at the rear pillars; a lifted edge or a piece that flexes means the recall is open. A separate complaint reports water from the A/C system and mould in the cabin, so check the front carpets for damp.

Repair cost: $0 with the recall — verify it was performed

Car cuts out at speed with the dash going dark, then every warning lights up; infotainment screen dies with the backup cameraMedium

Five electrical complaints, three of them a car that lost power while moving — once at 60 mph — with the dash going blank and then every indicator lighting when it restarted. Dealers found nothing twice; a roadside technician measured a low alternator once. The other report is the infotainment screen going fully black, which on this car also takes the backup camera with it. On the test drive, watch the dash for any flicker at idle and with the headlights, A/C and heated seats all on, and have a shop check charging voltage at idle and 2,000 rpm.

Repair cost (estimate): $400–$2,000 for an alternator or a head unit outside warranty; $0 inside it
