Kia K5 fuel tank fire + DCT power loss recalls affect 300,000+ owners. California lemon law may entitle you to a full buyback. Free case review.
The 2021-2026 Kia K5 arrived as one of the most striking mid-size sedans in its class — a sleek, tech-loaded alternative to the Camry and Accord at a competitive price. But beneath the redesigned sheet metal, two serious defects have affected hundreds of thousands of California K5 owners. The biggest is a fire risk inside the fuel system. Recall 25V794 (Kia SC356, November 2025) covers 250,547 K5 sedans — every 2021-2024 model equipped with the 1.6-liter turbocharged engine. The problem: a check valve inside the purge control solenoid valve deteriorates over time, allowing pressurized air from the intake manifold to flow backward into the fuel tank. The tank expands, contacts hot exhaust components underneath the car, and can melt or crack — creating a fuel leak that the NHTSA plainly labels a fire risk. Repair notifications were not mailed to owners until January 2026, meaning many owners drove for months unaware. The second major defect targets a smaller but equally serious group: 2021-2023 K5s paired with the 2.5-liter turbocharged engine and eight-speed dual-clutch transmission (DCT). Recall 22V760 (Kia SC250) documented that an electric oil pump inside the transmission could fail without warning — cutting all drive power 20 to 30 seconds after a dashboard warning appeared. Drivers reported the 'Stop Safely Immediately' message and then complete loss of propulsion, including on the freeway. For California owners who purchased or leased a K5 that has required multiple dealer visits — or who are waiting on a recall remedy that still has no permanent fix — the state's lemon law may provide a path to a full vehicle repurchase.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.
Popping or gurgling sound from fuel tank area; check engine light illuminates; rough idle or engine won't start; fuel odor; inability to refuel normally; visible fuel tank deformation
Fuel odor in or around engine bay; fuel stain or wet area near high-pressure fuel pump; illuminated warning light; potential fire in engine compartment
Dashboard warning chime and 'Stop Safely Immediately' message appear; vehicle loses all drive power 20–30 seconds later; transmission disengages at highway speed; vehicle rolls to a stop with no acceleration
No outward pre-crash symptom; side curtain airbags fail to deploy during a crash that warrants deployment; may only be discovered during post-accident inspection or recall inspection
Sudden and unexpected increase in steering wheel resistance or stiffness while driving, particularly when Lane Following Assist is active on curves; steering feels heavy without warning
AWD system inoperative or intermittently drops out; warning light on dashboard; vehicle reverts to front-wheel drive only; DTCs P195800 and/or P196000 stored; reduced traction on slippery roads

Dashboard warning chime and 'Stop Safely Immediately' message appear; vehicle loses all drive power 20–30 seconds later; transmission disengages at highway speed; vehicle rolls to a stop with no acceleration
Sudden complete loss of drive power at highway speed is a safety-critical drivability defect; failure to remedy within a reasonable number of attempts supports a lemon-law claim. Multiple dealership visits without lasting resolution are common.
Inspect and, if necessary, replace transmission; reprogram transmission control unit (TCU) with updated software; free of charge at Kia dealership
Popping or gurgling sound from fuel tank area; check engine light illuminates; rough idle or engine won't start; fuel odor; inability to refuel normally; visible fuel tank deformation
Fire risk from a melting fuel tank is a catastrophic safety defect. At 250,547 recalled units this is the highest-volume K5 recall. If owner experienced tank damage, repeated repair attempts, or a fire-related incident, this strongly supports a lemon-law claim.
Replace PCSV check valve; inspect fuel tank and replace if damaged; dealer software update; all free of charge (Kia SC356)
No outward pre-crash symptom; side curtain airbags fail to deploy during a crash that warrants deployment; may only be discovered during post-accident inspection or recall inspection
A pre-existing airbag non-compliance is a safety defect that existed at delivery. If airbags failed to deploy in a crash on a vehicle within the recall population, this substantially supports a lemon-law or products liability claim.
Inspect installed condition of side curtain airbags; reinstall correctly if improperly installed; free of charge at Kia dealership (Kia SC263)
Fuel odor in or around engine bay; fuel stain or wet area near high-pressure fuel pump; illuminated warning light; potential fire in engine compartment
Small population recall (726 K5 units) but a fire-risk defect from delivery. Any owner who experienced a fire or fuel leak event will have strong grounds. Document all dealership visits.
Inspect fuel pipe for affected lot date code; replace and re-torque fuel pipe properly; free of charge (Kia's recall number SC172-related)
Sudden and unexpected increase in steering wheel resistance or stiffness while driving, particularly when Lane Following Assist is active on curves; steering feels heavy without warning
Sudden steering resistance while operating ADAS features is a safety defect. Small recall population (846 units) but any owner reporting repeated steering incidents has strong grounds.
R-MDPS software update performed at dealership; free of charge (Kia SC213)
AWD system inoperative or intermittently drops out; warning light on dashboard; vehicle reverts to front-wheel drive only; DTCs P195800 and/or P196000 stored; reduced traction on slippery roads
Repeated AWD failures requiring multiple dealership visits for actuator replacement on a vehicle sold as AWD supports a lemon-law claim, particularly in California where performance-as-advertised is relevant.
Replace AWD coupling actuator assembly per TSB TRA108; confirm DTCs P195800/P196000 before replacement
HVAC blower stops working or delivers no airflow; reduced or no heat or air conditioning; blower may cut out intermittently at high fan settings before failing completely
Kia's 15-year/180,000-mile warranty extension is an implicit admission of a systematic defect. If owner has had multiple HVAC failures or repeated dealership visits, this supports a lemon claim especially if other issues co-exist.
Relocate blower motor 40A fuse to another circuit within the multi-fuse; covered under Kia warranty extension (15 years/180,000 miles from in-service date); per WTY037
Touchscreen freezes or becomes unresponsive; map shows inaccurate location; Google Maps or Waze via wired Apple CarPlay shows significant delay or locks up; infotainment requires reboot to restore function
Repeated infotainment failures alone rarely meet lemon-law threshold in California but may contribute to a cumulative substantial-impairment argument alongside safety-system defects.
Software update for AVN 5.0 Wide unit via USB flash drive or Navigation Updater (update.kia.com); per TSB ELE320

Every item below comes from this vehicle's documented defects. The more you recognize, the more a free case review is worth your time.
California's Song-Beverly Consumer Warranty Act applies to new vehicles purchased or leased in the state. The law presumes a substantial defect exists when a manufacturer has failed to repair a safety-related problem after two attempts, failed to repair any other substantial defect after four attempts, or when the vehicle has been out of service for 30 or more cumulative days during the warranty period. If your K5 qualifies, you may be entitled to a full repurchase of the vehicle — your purchase price less a modest mileage offset for use — or a comparable replacement. Kia is required to pay your attorney's fees if you prevail under Song-Beverly, meaning most California lemon law cases cost the owner nothing out of pocket. The K5's fuel tank fire defect (250,547 units recalled) and DCT power-loss defect are each documented safety issues with NHTSA recall campaigns. Owners with multiple dealer visits for either defect — or who experienced a fire, fuel leak, or sudden loss of propulsion — are strong candidates for a lemon law evaluation. The above is general information only and is not legal advice; results depend on the specific facts of your case.
“Could not duplicate” doesn't mean the defect isn't real. Here's exactly what to do to protect a potential California lemon-law claim.
Document the moment it happens. Photos, video, and screenshots of any warning lights — with the date and the mileage.
Get a repair order every visit — even “found nothing.” That paperwork is the foundation of a claim.
Check your VIN at nhtsa.gov/recalls. Note any recall that has no available remedy yet.
Track your out-of-service days. California law counts the cumulative days your vehicle spends in the shop.
Keep loaner & rental records. Alternate-transport paperwork during long repairs matters.
Save everything in one place. Symptoms, dates, repair orders, and every repeat visit — the intermittent ones especially.
If the dealer marks your repair order 'could not duplicate' (CND) or 'no trouble found' (NTF), that visit still counts as a repair attempt under California's lemon law. Here is how to protect your case: 1. Before every dealer visit, note the exact symptom, the exact warning message on the screen (photograph it if you can do so safely), the date, time, mileage, weather conditions, and what you were doing when the problem occurred. 2. For the fuel system issue: tell the advisor you are experiencing symptoms consistent with recall 25V794 (Kia SC356) — specifically, any check engine light, fuel odor, or unusual sounds from the tank area. Ask them to inspect the PCSV check valve condition and document whether the recall repair has been completed. 3. For the DCT power-loss issue: ask the service advisor to pull all stored and historical Diagnostic Trouble Codes (DTCs) from the TCU — not just active codes. Transmission fault codes related to the electric oil pump may have cleared by the time the car reaches the dealer but will remain in history. Reference recall 22V760 and Kia SC250 by name and number. 4. Keep a copy of every repair order — including CND visits, parts-on-order visits, and days the car stayed at the dealer. Under California law, days out of service accumulate toward the 30-day lemon law presumption regardless of the reason. 5. If the dealer tells you recall parts are on backorder, ask for that statement in writing on the repair order. Waiting time for recall parts counts toward your days out of service.
The Kia K5's recall record has two standout concerns that every owner should know. First, the 250,547-unit fuel tank fire recall (25V794) is the highest-volume K5 recall issued to date — it covers essentially every 2021-2024 K5 with the base 1.6T engine, and Kia did not mail owner notifications until January 2026, more than two months after the recall was issued. Owners who experienced a fuel odor, check engine light, or refueling difficulty during that gap may have been driving a fire-risk vehicle without knowing it. Second, the DCT power-loss recall (22V760) describes a failure mode that is genuinely dangerous: the car gives you 20-30 seconds of warning before it cuts all drive power at freeway speed. That is a safety defect by any reasonable measure. If you own a 2021-2026 K5 and have been back to the dealer more than once for either of these problems — or for any of the other documented recalls — a California lemon law evaluation is worth a free phone call.

If you own a 2021, 2022, 2023, or 2024 Kia K5 equipped with the 1.6-liter turbocharged engine, your vehicle is likely covered by NHTSA recall 25V794 (Kia SC356), issued November 17, 2025. The recall covers 250,547 K5 units. The defect is a purge control solenoid valve (PCSV) check valve that deteriorates over time, allowing pressurized air from the intake manifold to flow backward into the fuel tank. The expanding tank can contact hot exhaust pipe components underneath the car, causing the tank to melt or crack and creating a fuel leak that NHTSA identifies as a fire risk. Owner notification letters were mailed beginning January 16, 2026. The remedy — check valve replacement and fuel tank inspection, at no cost — is available at Kia dealerships. Check your VIN at nhtsa.gov to confirm your vehicle's recall status. If your dealer has already performed the repair but you previously experienced a fuel odor, tank damage, or a related incident, document everything — those events may support a lemon law evaluation.
This is the exact failure mode documented under NHTSA recall 22V760 (Kia SC250, October 2022), which covers 2021-2023 Kia K5 sedans equipped with the 2.5-liter turbocharged engine and the eight-speed dual-clutch transmission (DCT). The defect: a supplier quality problem caused insufficient soldering on the electric oil pump circuit board inside the DCT. When the pump fails, the transmission loses hydraulic pressure and disengages drive — cutting all power to the wheels roughly 20 to 30 seconds after the warning message appears. The recall covers 69,038 total units (K5 and Sorento combined); the K5 portion includes vehicles produced between November 2020 and August 2022. If this has happened to you once and the dealer reprogrammed the transmission control unit but did not replace the transmission, monitor the vehicle. If the power-loss event occurs again after a prior repair attempt, that pattern is exactly the repeat-repair scenario California's lemon law is designed to address.
Yes — those are two of the primary early symptoms documented under recall 25V794. The check valve failure that allows intake air to pressurize the fuel tank can trigger a check engine light as an evaporative emission fault, and a cracked or melted fuel tank can produce a noticeable fuel odor inside and outside the vehicle. Other warning signs include a gurgling or popping sound from the rear of the car, difficulty getting the gas pump to click off during refueling (because the tank pressurizes and triggers the auto-shutoff prematurely), and visible deformation of the underside of the fuel tank. If you notice any of these, take the vehicle to a Kia dealer, reference recall 25V794 and SC356 by number, and ask specifically whether the PCSV check valve has been inspected and whether the fuel tank shows any sign of damage. Ask the service advisor to document the inspection results on your repair order. If the tank is already damaged, insist on tank replacement — not just valve replacement — as specified in the recall remedy.
You may qualify under California's Song-Beverly Consumer Warranty Act. The law applies to new vehicles purchased or leased in California and creates a presumption of a lemon when: (1) the manufacturer fails to repair a safety-related defect after two attempts, (2) fails to repair any substantial defect after four attempts, or (3) the vehicle is out of service for 30 or more cumulative days during the warranty period. Both major K5 defects — the fuel tank fire risk and the DCT power-loss defect — are confirmed NHTSA safety recalls. Owners who experienced the sudden loss of drive power at freeway speed, or who had a fuel odor or tank damage event before the recall remedy was available, are strong candidates for evaluation. If you qualify, Kia must repurchase the vehicle at the original purchase price less a reasonable mileage allowance, or provide a comparable replacement. Kia is also required to pay your attorney's fees if you prevail, so most California lemon law cases cost the owner nothing out of pocket. This is general information only and is not legal advice.
Yes. Under California's Song-Beverly Act, a 'could not duplicate' (CND) or 'no trouble found' (NTF) repair order is still a repair attempt. The number of attempts that matter under the law is the number of times you brought the vehicle in for the same substantial defect — not the number of times the dealer successfully fixed it. For the K5 specifically: both the fuel tank fire defect and the DCT power-loss defect are intermittent by nature. The fuel system check valve may not produce visible tank damage on the first visit if the deformation is minor. The DCT transmission fault clears between events and may not generate active codes by the time the car reaches the service bay. If the dealer closes your visit as CND, ask them to pull historical DTC records from the transmission or engine control modules — cleared fault codes are still evidence. Keep every repair order, even the ones marked CND, and track the date and mileage of every visit.
Yes. Kia issued a warranty extension — TSB WTY037, dated August 14, 2024 — specifically for 2021-2022 K5 vehicles whose HVAC blower motor has failed. The root cause is damage to the 40-ampere multi-fuse terminals on the blower motor circuit, caused by extended use of the HVAC at high fan settings. When the terminal burns out, the blower motor stops delivering airflow entirely. Kia extended the warranty coverage on this defect from the standard five years/60,000 miles to 15 years/180,000 miles — an unusually long extension that signals Kia recognized this as a systematic manufacturing problem. The repair (relocating the 40-amp fuse within the multi-fuse assembly) is covered at no charge at any Kia dealership within the extended warranty period. If your dealer has refused to perform this repair under warranty, or if the blower has failed more than once, document the visits — repeated HVAC failures that are part of a broader pattern of defects can contribute to a lemon law claim in California.
