2010-2023 Kia Soul Problems: 15 Known Issues

On early second-generation (PS) Souls the headlamp circuit is switched directly through the contacts inside the combination (multi-function) stalk on the steering column rather than through a relay. Those contacts burn and wear, and the resistance rise makes both low and high beams flicker, dim, or cut out entirely — classically when the turn signal is operated, because the shared stalk assembly loads the same worn contact set. Owners describe headlights going fully dark for the duration of a turn signal cycle, which is a night-driving safety problem, not a nuisance. Kia acknowledged the pattern with TSB ELE152 and then extended the New Vehicle Limited Warranty on the multi-function switch assembly from 5yr/60k to 15 years / unlimited miles for 2014 MY Souls built 7/21/2013 through 6/20/2014 — a warranty extension of that length is effectively an admission of a design defect.

The 27 kWh SK Innovation pouch cells used in the first-generation Soul EV degrade far faster than the industry norm, and — critically — the loss is not linear. Owners tracking state of health with OBD tools report long plateaus followed by cliff-like drops; one documented case lost 15 percentage points of SOH in three months over roughly 4,000 miles. The practical result is a car that quietly stops being usable for its original commute: indicated range falls well below the 93-mile EPA figure, the guess-o-meter becomes erratic, and DC fast-charge sessions taper early. Because Kia's capacity warranty triggers at below 70% SOH, the shape of this degradation curve matters — cars sitting at 72-75% can drop under the threshold quickly, and owners near the end of the warranty term should be measuring, not guessing.

The Soul EV's on-board charger converts AC from a wall outlet or Level 2 EVSE into DC for the pack; DC fast charging over CHAdeMO bypasses it entirely. That produces the diagnostic signature owners keep reporting across a decade of the model's life: the car refuses to charge on both the Level 1 cord and the Level 2 station, throws a charging fault, and yet fast-charges normally. Some cars announce it first with repeated clicking from under the hood and blinking charge-port lamps for weeks or months before the unit dies outright. Failures were still occurring on 2018 builds, four years after launch, so this is a design-life problem rather than an early-production defect. One related cause is worth knowing: in a documented 2015 case a failed electric water pump let the OBC overheat and fail, a replacement OBC alone did not restore charging, and the dealer also found a blown 40A fuse in the high-voltage junction box.

If you own a 2023 Kia Soul, it may be included in Kia America's recall of vehicles whose Idle Stop & Go electric oil pump assembly has an electronic controller built with damaged electrical components. Kia's concern is that those damaged components let the pump overheat, and NHTSA states the consequence plainly: an electric oil pump assembly that overheats increases the risk of a vehicle fire. This is a manufacturing defect in the controller itself rather than something an owner causes through use or neglect, and NHTSA classifies it under the automatic transmission fluid/lubricant pump. The recall spans 39,765 vehicles campaign-wide, a total that includes the 2023 Soul, 2023 Sportage and 2023-2024 Seltos together. Because the risk is fire, Kia's interim advice for Soul owners was to park outside and away from structures rather than in a garage or carport until the vehicle has been repaired.

The Hydraulic Electronic Control Unit (HECU/ABS module) can develop an internal electrical short (fluid leakage plus localized PCB melting was found in retrieved units), producing excessive current that can cause an engine-compartment fire while parked or driving. NHTSA recall 23V-652 covers 349,309 2011-2013 Souls equipped with Electronic Stability Control, part of the broader Kia/Hyundai 'park outside' fire-risk campaign. Owners were told to park outside and away from structures until repaired.

Kia recalled approximately 2,689 Soul EVs because an internal short circuit can develop between the anode and cathode inside cells of the E400 high-voltage battery pack, and that short can start a fire while the vehicle is being driven. Kia attributes it to abnormally excessive precipitate forming inside the cells; three thermal incidents were reported. The population is unusual and easy to miss: it covers 2018-2019 Soul EVs built 7/3/2017 through 9/28/2018 with the factory E400 pack, AND 2015-2017 Soul EVs that had their original pack replaced under warranty with an E400 unit — so a first-generation car that already got a 'good' battery can be the affected one. Warning signs owners see before anything dramatic are charging that never completes, range that fluctuates or drops, and the EV warning lamp.

Kia America is recalling certain 2021-2023 Kia Soul vehicles under NHTSA campaign 25V099000 (Kia's internal number SC336). On the affected Souls, the piston oil rings may have been manufactured incorrectly. That manufacturing defect can lead to engine damage. NHTSA's stated consequence is blunt: engine damage can cause the vehicle to stall or catch fire, which raises the risk of a crash or injury. A stall in a small hatchback like the Soul is dangerous anywhere it happens in traffic, and the fire risk is what pushes this beyond an ordinary durability complaint. The campaign covers 137,256 vehicles in total across every model included in the recall — that figure is campaign-wide and is not a count of Souls. Owner notification letters for this campaign were mailed April 4, 2025, so a Soul that changed hands since then may have an owner who never saw the letter.

NHTSA recall 19V120000 (Kia SC176) covers 2012-2016 Soul vehicles with the 1.6L GDI engine. Excessive exhaust-gas temperature can damage the catalytic converter, leading to abnormal combustion, piston damage, connecting-rod failure, stall or fire. Kia’s later SC176Y bulletin addresses certain previously repaired vehicles with P0420, with or without a P030X misfire code.

NHTSA recall 21V259000 (Kia SC209) covers certain 2020-2021 Soul vehicles with 2.0L Nu MPI engines whose piston oil rings may not have been properly heat-treated. Kia communication 11017169/SST082 indexes a later PNSS vibration-inspection process to certain 2020-2023 Soul vehicles and describes ring-related cylinder-wall damage, increased oil consumption, abnormal noise, oil-pressure warning and P1327. That later bulletin does not make every 2022-2023 vehicle part of recall 21V259.

NHTSA recall 17V608000 (Kia SC155) covers 2014-2016 Soul vehicles. The pinion plug may allow the pinion gear to separate from the steering-gear assembly, causing loss of steering and increasing crash risk. The campaign supersedes 14V332 and 15V736, including vehicles previously repaired under those campaigns.

Souls with the 1.6L Turbo-GDI and 7-speed dry dual-clutch transmission exhibit low-speed clutch judder (a body shake accelerating from a stop, worst on cold/humid mornings), harsh engagement, and hesitation. The dry clutches glaze/wear during stop-and-go creeping. Kia's diagnosis is a creep-driving test: if the body vibrates without steering-wheel shudder, it is clutch judder. TSB TRA083 (Souls built 8/8/2016-10/27/2016 and 11/24/2018-4/2/2020) remedies confirmed judder by replacing the dual-clutch assembly and upgrading the TCU.

Kia recalled certain 2023 Soul vehicles because a manufacturing error in the side curtain air bag modules can cause them to deploy unexpectedly — that is, without a crash. In a Soul, the curtain bags run along the headliner above the side windows, so an unexpected deployment happens right beside the driver's and passengers' heads. NHTSA lists the consequence plainly: an air bag that deploys unexpectedly can increase the risk of injury or crash, since a sudden deployment while driving can both strike occupants and startle the driver. The campaign (Kia internal number SC289) covers 2,967 vehicles in total across every model included in the recall; that figure is campaign-wide and is not a count of Souls. Owner notification letters were mailed January 31, 2024.

The optional panoramic glass sunroof can spontaneously shatter without impact, often at speed, showering occupants with glass and accompanied by a loud bang. NHTSA opened an investigation into Hyundai/Kia panoramic sunroof shattering in 2013 (expanded 2014) but closed it without finding a safety-related defect, citing possible road-debris contribution. A long-running class action alleged a manufacturing/tempering defect; after roughly a decade it was ultimately dismissed in Kia's favor.

The Soul EV (2015-2020) can develop a whining or grinding noise from the electric drive motor due to bearing wear. The front motor bearing deteriorates prematurely, particularly in cold climates. The noise is most noticeable at low speeds when other road noise is minimal. Kia has replaced drive motors under warranty for some owners.

Kia TSB CHA074 covers 2010-2013 Soul vehicles in its listed production range and attributes a knock or click while turning at a stop to premature wear of the MDPS motor’s flexible coupling. Kia WTY013 separately extended flexible-coupling coverage to 10 years/unlimited mileage for 2012-2013 Soul vehicles; it does not extend every other MDPS component or the 2010-2011 vehicles.
