Overview
The Kia Seltos is a subcompact crossover SUV that entered the US market for the 2021 model year. Built on the Kia SP2 platform and sharing underpinnings with the Hyundai Venue and Kia Soul, the Seltos slots below the Sportage in Kia's lineup. US models are offered with a 2.0L naturally aspirated four-cylinder or a 1.6L turbocharged four-cylinder paired with either a CVT, IVT, or 7-speed dual-clutch transmission. The Seltos has been generally well-regarded for reliability in its class, though owners report recurring EVAP system codes, IVT/CVT transmission hesitation, infotainment glitches, and ADAS sensor calibration issues. A second-generation model debuted for the 2025 model year with revised styling and updated powertrains.
Quick Summary

Common OBD2 Codes
| Code | Frequency | Notes |
|---|---|---|
| P0456 | Very Common | EVAP system very small leak detected. The most frequently reported check engine code on the Seltos. Purge control solenoid valve failures and loose or cracked EVAP hose connections are primary causes. Many owners report the code returns after purge valve replacement. |
| P0442 | Common | EVAP system small leak detected. Often occurs alongside P0456. Fuel cap seal degradation and charcoal canister vent valve issues are common triggers. |
| P0300 | Common | Random/multiple cylinder misfire detected. Reported on both 2.0L and 1.6T engines. On the 1.6T (GDI), carbon buildup on intake valves is an early contributing factor; on the 2.0L MPI, spark plug or ignition coil degradation is more typical. |
| P0301 | Common | Cylinder 1 misfire detected. Ignition coil failures are the most common cause on both engine variants. Spark plug replacement at factory interval (60k miles) is recommended to prevent. |
| P0171 | Common | System too lean Bank 1. On the 1.6T GDI, high-pressure fuel pump degradation and injector deposits contribute to lean conditions. On the 2.0L MPI, MAF sensor contamination or vacuum leaks at the intake manifold gasket are typical. |
| P0128 | Occasional | Coolant temperature below thermostat regulating temperature. Thermostat sticking open is a known failure mode, causing prolonged warm-up, reduced heater output, and decreased fuel economy. |
| P0507 | Occasional | Idle control system RPM higher than expected. Electronic throttle body carbon buildup and idle speed relearn procedure issues reported after battery disconnection. |
| P0741 | Occasional | Torque converter clutch circuit performance or stuck off. Reported on IVT-equipped 2.0L models; often associated with shudder or hesitation during light acceleration at highway speeds. |
| P0730 | Occasional | Incorrect gear ratio. Noted on 7-speed DCT models during cold operation. Software calibration updates from Kia have addressed many instances. |
| U0100 | Occasional | Lost communication with ECM/PCM. Sporadic CAN bus communication faults reported, frequently tied to low battery voltage or a failing 12V battery rather than ECM hardware failure. |
| P0420 | Occasional | Catalyst system efficiency below threshold Bank 1. Relatively early catalyst degradation reported on higher-mileage 2021–2022 units, particularly those that experienced repeated lean conditions from EVAP or fuel system issues. |
| C0561 | Occasional | ABS system disabled — invalid data received. ABS/ESC control module communication faults reported following low battery events or after collision. Module reset or software update typically resolves. |
Known Problems
The Intelligent Variable Transmission (IVT) on 2.0L FWD models exhibits noticeable hesitation and a rubber-band feel during acceleration from a stop, particularly in cold weather. Some owners report a shuddering sensation at 30–45 mph under light throttle that is consistent with torque converter clutch slip. Kia has released software calibration updates that partially improve shift feel, but a subset of owners continues to experience the issue. Transmission fluid changes with Kia-approved SP-IV-M fluid have helped in some cases.
Typical mileage: 5,000–60,000 miles
Shop parts for this repairThe 7-speed wet dual-clutch transmission on 1.6T AWD models is prone to jerky low-speed engagement, creeping forward before driver input when in Drive, and harsh downshifts. Cold-weather operation significantly worsens the symptoms. Kia has acknowledged the behavior and issued multiple software updates; some owners ultimately required clutch pack replacement under warranty.
Typical mileage: 5,000–50,000 miles
Shop parts for this repairThe Seltos EVAP system is highly sensitive and produces frequent check engine lights from small leaks or component failures. The purge control solenoid valve, canister close valve, and fuel cap seal are all documented failure points. Many owners report the check engine light returning within a few thousand miles after purge valve replacement. In some cases the evaporative canister itself requires replacement.
Typical mileage: 15,000–60,000 miles
Shop parts for this repairThe 8-inch and 10.25-inch touchscreen infotainment systems on SX and SX Prestige trims frequently freeze, reboot spontaneously, or lose wireless Apple CarPlay/Android Auto connectivity. Navigation and backup camera feeds can become unresponsive. Kia dealers have released multiple over-the-air and dealer-applied software updates, but the issue recurs on some units. A subset of complaints involves the head unit requiring replacement under warranty.
Typical mileage: Any mileage
Shop parts for this repairThe front radar and camera-based FCA system applies emergency braking unexpectedly in the absence of an actual hazard, particularly at highway speeds when passing overpasses, large road signs, or in heavy rain. False activations create a rear-end collision risk. Kia has issued software updates to adjust detection thresholds, but NHTSA received numerous complaints prior to the recall.
Typical mileage: Any mileage
Shop parts for this repairAWD Seltos owners report accelerated front brake pad and rotor wear, with some replacing pads as early as 20,000 miles. The brake bias calibration and the relatively light-duty brake hardware appear undersized for the AWD model's curb weight when combined with aggressive regenerative or sport driving.
Typical mileage: 20,000–45,000 miles
Shop parts for this repairThe optional panoramic sunroof develops wind noise and rattles, particularly at highway speeds. Some owners report water intrusion through degraded corner seals, leading to wet headliner and potential electrical issues. Kia dealers address this with seal adjustments or replacement, but recurrence is common.
Typical mileage: 10,000–40,000 miles
Shop parts for this repairMultiple owners report abnormally fast 12V battery discharge, particularly when the vehicle sits unused for several days. The always-on telematics and UVO Connect modules maintain a parasitic draw that can deplete an undersized OEM battery. Early battery failure (within 2–3 years) has been reported, and Kia extended the battery warranty on some model years.
Typical mileage: Any mileage
Recalls
The FCA system software may cause unintended automatic emergency braking due to false target detection in certain road conditions. Software update required to recalibrate detection thresholds and reduce false activations.
Engine control unit software may not correctly manage idle speed following a cold start, potentially causing the engine to stall. An ECU software update corrects idle control parameters.
A software error may prevent the rearview camera image from displaying when the transmission is shifted into Reverse, increasing the risk of a backing collision. Software update required.
The low-pressure fuel pump may fail intermittently on 2.0L MPI models, causing engine stall while driving. Replacement of the affected fuel pump assembly required.
Certain side curtain airbag inflators may rupture upon deployment, potentially projecting metal fragments at vehicle occupants. Airbag assembly replacement required.

| P0128 | Occasional | Coolant temperature below thermostat regulating temperature. Thermostat failures consistent with prior generation observed on some early 2025 units. |
| U0100 | Occasional | Lost communication with ECM/PCM. CAN bus faults associated with low 12V battery voltage reported on new generation, consistent with first-generation pattern. |
| P0730 | Occasional | Incorrect gear ratio detected. Early reports on the new 8-speed automatic during cold operation; software calibration updates anticipated from Kia. |
| U0155 | Occasional | Lost communication with instrument panel cluster. Sporadic cluster communication faults reported on 2025 units, often linked to infotainment system reboot cycles. |
Known Problems
The redesigned 2025 Seltos features a revised dual-screen infotainment interface. Early adopters report system freezes, intermittent loss of wireless CarPlay/Android Auto pairing, and slow boot times. Over-the-air updates have been pushed by Kia but the issue has not been fully resolved across the fleet.
Typical mileage: Any mileage
The EVAP system design carried over from the prior generation continues to generate frequent check engine lights. Purge valve and canister close valve replacement remain the primary dealer remedies, though recurrence rates are similar to first-generation vehicles.
Typical mileage: 10,000–40,000 miles
Shop parts for this repairThe new 8-speed automatic transmission replacing the DCT on the 1.6T shows early reports of hunting between gears in mild hill conditions and slightly harsh kickdown behavior. Kia has acknowledged the concern and is developing a software calibration update. Insufficient field data to fully characterize long-term reliability.
Typical mileage: Under 15,000 miles
Forward collision warning and lane keeping assist systems generate nuisance alerts and occasional false braking events in the new generation, consistent with earlier model year reports. Camera and radar sensor recalibration after windshield replacement is a known additional cost for owners.
Typical mileage: Any mileage
Shop parts for this repairMultiple 2025 Seltos owners report wind noise ingress around the A-pillars and front door seals at highway speeds, a build-quality issue consistent with some first-generation examples. Dealer adjustment of door seals or application of supplementary sealing tape resolves most cases.
