The loudest Sportage year we track, and the file is almost entirely engines that failed with nobody paying for them.

The second-loudest theme in this year is not a part, it is a refusal. "Engine failure and the dealership, corporation and warranty are refusing to replace the engine. My engine falls under an engine settlement." "Kia is refusing to submit or honor my engine replacement claim under the known engine defect class action/recall." Here is what the documents actually say. Kia's published engine short-block warranty extension for the Sportage — block, crankshaft and bearings, connecting rods and bearings, pistons, raised to 10 years or 120,000 miles and valid regardless of ownership changes — covers 2011 to 2014 model years. Nothing in Kia's Sportage bulletin file extends engine coverage to 2017. And there is no rod-bearing safety recall on any Sportage in this era: the engine recall people remember, 17V224, covers 2011 to 2013 Sportages only. So the 2017 has a detection campaign and an expired factory powertrain warranty. Owners citing a settlement are citing something no Kia Sportage document in our sources confirms for this model year.

This is the one year that gets free money, and most owners do not know about it. First, the door latches. Kia's bulletin states that on 2017 Sportages built between December 2015 and December 2016 the latches may stop working over time so the doors will not open from the outside handle, and Kia extended the door-latch warranty from 5 years and 60,000 miles to 10 years and unlimited miles, for the original or any subsequent owner. Second, the airbag control unit — the module that decides when the airbags fire. On 2017 Sportages built between December 2015 and April 2017, Kia extended coverage for repairs related to the airbag warning light coming on, from 5 years and 60,000 miles to 15 years and unlimited miles, and its procedure bulletin instructs dealers to replace the module outright when specific fault codes are stored. Kia published reimbursement forms for both, for owners who already paid. If the airbag light is on, or a door only opens from the inside, do not buy a part — book a dealer appointment.

Recall 21V137 covers 2017 to 2021 Sportages and Cadenzas: the electrical circuit in the Hydraulic Electronic Control Unit — the HECU, the module that runs the anti-lock brakes — can short-circuit and start a fire in the engine compartment. Kia advises parking outside and away from buildings until it is repaired, and dealers replace fuses in the electrical junction box free, with a software update on cars with an electronic parking brake. Kia's code is SC206. Recall 22V703 covers 2017 to 2022 Sportages fitted with a Kia tow-hitch harness, whether factory-fitted or dealer-installed: debris and moisture on the harness module's circuit board can short and cause a fire, parked or driving. Also park outside. Free inspection and, as needed, a new fuse or harness module. Kia's code is SC249. Both are open on this year. Run the VIN.

Recall 18V907 covers 2011 to 2018 Sportages that already had a replacement engine fitted — under an earlier recall, under warranty, or through the knock-sensor campaign. The high-pressure fuel pipe at the fuel-pump outlet may have been damaged, misaligned or wrongly torqued during that work, which can leak fuel and start a fire. Free inspection and replacement, Kia code SC172. Given how many 2017 engines the complaint file shows being replaced, this one is worth checking on any car with a newer engine in it. Separately, recall 16V862 covers 2017 Sportages built between December 2015 and August 2016 that carry the accessory trailer-hitch wiring harness: a tow-module fault can leave the trailer brake lights permanently lit, which fails the federal lighting standard and confuses drivers behind you. Free harness replacement, Kia code SC142.

A US repair channel covering this generation puts the practical version well. The knock sensor sits underneath the intake manifold, so reaching it means removing the manifold — this is not a fifteen-minute job. The symptom is a flashing check-engine light and limp mode with code P1326. And the crucial caveat: before replacing the sensor, check for obvious damage, because if the engine is knocking there may be internal engine damage, and check the oil level. That is the right order for a buyer too. A P1326 on a test drive is not automatically a dead engine, but it is never automatically just a sensor either. Get it diagnosed before money changes hands.

A distinct secondary cluster in the 2017 file is the catalytic converter — the exhaust device that cleans the gases. "The Catalytic Converter in the Kia. We were driving to Texas… and it cut off right in the middle of the highway." Another owner describes a smell of gas in the oil, a converter replacement, and then the same trouble again within a year. A community mechanic explains the mechanism for this generation of Hyundai-Kia engines: the converter sits very close to the engine, so unburnt fuel from a misfire overheats it, the internal ceramic breaks up, and fragments can be drawn back into the combustion chamber. That is a plausible route from a cheap ignition fault to an expensive engine, and it is a good reason not to drive a Sportage with a misfire.

Kia's bulletins describe customer-satisfaction campaign CS2302, which upgrades the body-control software on 2017 to 2022 Sportages built between December 2015 and December 2021, on cars "which may not be equipped with an immobilizer" — the chip that prevents an engine starting without the correct key. The upgrade adds anti-theft ignition logic that arms when the car is locked with the fob. Companion campaigns fit a reinforced ignition-cylinder protector with window decals and update Kia's own remote-start module for compatibility. Kia describes the software as addressing the social-media theft method and offers it free at authorised dealers. These are campaigns, not safety recalls. Confirm the software was applied, and get an insurance quote before you buy rather than after.

Kia is running a voluntary emissions service campaign, SC340, that reflashes the engine computer on 2017 to 2022 Sportages with the 2.4-litre Theta II engine. Kia's bulletin states the reason directly: certain 2016 to 2022 vehicles with these engines may have engine calibrations that were not optimised for emissions standards under certain conditions, and may release pollutants exceeding federal and California limits. It is free. Unlike the equivalent Hyundai campaign, Kia's bulletins describe no side effect afterwards — so if a 2017 Sportage develops a driveability complaint after the update, that is not documented as expected behaviour and should be diagnosed rather than shrugged off.
