On the 2010-2018 Kia Forte, two Kia safety recalls match this page’s retained year groups. Under 18V363000 (SC165), the airbag control unit in certain 2010-2013 Forte vehicles can suffer electrical overstress during a frontal crash, preventing the frontal airbags and seatbelt pretensioners from deploying. Under 22V031000 (SC226), the ACU cover in certain 2017-2018 Forte vehicles can contact a memory chip, illuminate the airbag warning light with DTC B1620 and deactivate the airbags.
Airbags or pretensioners may not deploy in a crash
How to Fix
Check the VIN for both recalls. For 18V363000, Kia installs an extension wire-harness kit between the ACU and vehicle harness. For 22V031000, Kia updates ACU software when B1620 is absent and replaces the ACU when B1620 is present. Both remedies are free and VIN-specific. No retail airbag-control part should be purchased from this page. If the airbag warning light stays on, follow Kia’s recall instructions and arrange dealer diagnosis.
On the 2011-2021 Kia Forte, forte models built with a mechanical turn-key ignition (rather than push-button start with a smart key) were sold in the US without an engine immobilizer. The steering-column shroud can be pried off and the ignition lock cylinder pulled, exposing a splined shaft that spins with the metal end of a USB-A connector or a screwdriver, cranking and starting the car in well under a minute. Because no transponder challenge exists, the ECU sees a normal start. The resulting theft wave (publicized on TikTok/social media as the 'Kia Boyz' challenge) drove huge theft and vandalism losses on 2011-2021 Forte, and several insurers refused to write comprehensive coverage on affected VINs. NHTSA declined to force a defect recall - immobilizers are not federally mandated and criminal acts are not a defect - so Kia responded with a voluntary customer-satisfaction software campaign instead.
Common Symptoms
Vehicle stolen or broken into
Steering column shroud pried apart and ignition lock cylinder pulled out
Car starts without the key
Broken rear quarter window
Insurer refuses comprehensive coverage or raises premium
How to Fix
Have the free Kia anti-theft software upgrade installed at a Kia dealer (roughly 1.5-2 hours). It reflashes the body/immobilizer-related control modules so that locking the doors with the fob arms the factory alarm and enables an 'ignition kill' - the engine will not crank unless the car is unlocked with the key/fob - and it extends the alarm sound from 30 seconds to one minute. Check VIN eligibility at Kia's anti-theft support page. Vehicles whose module hardware cannot accept the flash get a free ignition-cylinder protector and/or a steering-wheel lock. Owners commonly add an aftermarket kill switch, a wheel lock, or a slotted ignition-cylinder shield as belt-and-suspenders. Note the flash changes behavior of some aftermarket remote-start systems, which may need reconfiguration afterward.
On the 2010-2018 Kia Forte, excessive connecting rod bearing wear on the Theta II and Nu engines can cause the engine to knock, seize, and stall without warning while driving, with a documented risk of an engine-compartment fire. This is the failure mode behind the NHTSA/Kia KSDS recall and the Hyundai-Kia engine class settlement, distinct from routine oil-consumption knock. Owners report catastrophic bottom-end failure, metal in the oil, and no-restart. Root cause is manufacturing debris left in the crankcase restricting oil flow to the rod bearings.
Kia dealers apply the Knock Sensor Detection System (KSDS) ECU software update that triggers limp mode (DTC P1326) before catastrophic failure, inspect for oil/fuel leaks, and replace the long-block/short-block if bearing damage is found. Repairs are warranted 15 years/150,000 miles under the KSDS campaign and covered by the engine class-action settlement (reimbursement for prior repairs).
On the 2010-2018 Kia Forte, the CKP sensor on the Forte becomes heat-sensitive as it ages: the signal drops out once the engine bay is hot, so the engine stalls when coming to a stop or at idle, then refuses to restart until it cools for 10-20 minutes. Owners describe the car cranking normally with no spark/injection event and eventually setting P0335 (Crankshaft Position Sensor A Circuit). It is often misdiagnosed as a fuel pump or battery issue because the symptom is intermittent and disappears when the car is cold. Reported across the TD, Koup 2.4 Theta II, and YD/Forte5 cars.
Engine stalls when slowing to a stop, especially when warmed up
Cranks but will not start until it cools down
Long crank time
Tachometer drops erratically or reads zero while cranking
Check engine light
How to Fix
Confirm before replacing: watch RPM in live data while the engine stalls or during a hot no-start crank - RPM dropping to zero while cranking points at the CKP. Check the sensor connector and harness for oil contamination and chafing, and verify the tone-ring/flexplate teeth are not damaged. Replace with a genuine Kia sensor rather than a cheap aftermarket unit, as owners report repeat failures with off-brand parts. The sensor is inexpensive; most of the cost is access labor. If P0365/camshaft codes appear alongside it, inspect the CVVT circuit and harness rather than blindly replacing both sensors.
On the 2010-2013 Kia Forte, nHTSA recall 23V652000 (Kia SC284) covers certain 2010-2013 Forte and Forte Koup vehicles equipped with Electronic Stability Control. The Hydraulic Electronic Control Unit (HECU) may experience an electrical short that can cause an engine-compartment fire while the vehicle is parked or being driven. Kia and NHTSA advise affected owners to park outdoors and away from structures until the recall is completed.
Common Symptoms
ABS or malfunction warning light
Burning or melting smell
Smoke from engine compartment
How to Fix
Check the VIN for recall 23V652000. A Kia dealer installs new lower-amperage fuse or fuses to prevent an overcurrent condition in the HECU circuit, free of charge. This proposal does not recommend a retail HECU or fuse because the campaign remedy is VIN-specific and dealer-installed. If the ABS or malfunction light illuminates, or there is a burning smell or smoke, stop safely, turn the engine off and arrange towing to a Kia dealer.
On the 2010-2022 Kia Forte, two related A/C failures are common on the Forte. On older clutch-type systems (TD/YD), the compressor clutch coil fails or the air gap opens up, so the clutch will not pull in even with correct refrigerant charge and battery voltage at the connector - the A/C blows ambient-temperature air and the compressor never turns. On newer externally controlled variable-displacement systems (no clutch - the pulley always spins), the control valve or its electrical connector fails, so the compressor spins but never destrokes/strokes properly and cooling comes and goes with no obvious mechanical noise. Both are aggravated by slow refrigerant loss from the condenser and A/C line O-rings, which starves the compressor of oil and kills it outright, sending debris through the system.
Common Symptoms
A/C blows warm or ambient air
A/C cools intermittently, better at highway speed
Compressor clutch does not click on when A/C is switched on
Loud rattle or grinding when A/C is engaged
Refrigerant needs topping up every season
How to Fix
Diagnose in the right order: verify static and operating pressures, verify the clutch or control-valve command with a scan tool, and check for voltage at the compressor connector. Voltage present with no clutch engagement means a failed clutch coil - on older cars the clutch/coil/pulley can be replaced separately, which is far cheaper than a compressor. On variable-displacement systems, check the control valve and its connector before condemning the compressor. If the compressor has seized or shed metal, the condenser and expansion device/orifice must be replaced and the lines flushed, or the new compressor will fail again. Always find and fix the leak (commonly the condenser or a line O-ring) with dye or a sniffer before recharging.
On the 2010-2022 Kia Forte, forte wheel hub bearings wear out early relative to the rest of the car - owners report front bearings going noisy well inside 60,000 miles, sometimes on cars still under the basic warranty, and rear hub assemblies failing on YD sedans and Forte5s. The noise starts as a faint hum at 40+ mph, grows into a rumble or growl, and characteristically changes pitch or disappears when weight shifts off the bad corner during a gentle sweeping turn. Because the noise is intermittent at first it is frequently blamed on tire cupping. Left long enough the bearing develops play that upsets the ABS/wheel-speed signal and can set an ABS/ESC light.
Humming or growling noise that rises with vehicle speed
Noise changes or disappears when turning
Rumble felt through the floor at highway speed
Play at the wheel when rocked at 12 and 6 o'clock
ABS or ESC warning light in severe cases
How to Fix
Diagnose by driving in a wide S pattern - noise that loads up turning one way and quiets turning the other identifies the side. Confirm with a stethoscope on the knuckle or by spinning the wheel off the ground. On both front and rear the practical repair is a complete hub-and-bearing assembly rather than pressing a bearing into the old knuckle. Front replacement requires a new axle nut and knuckle bolts and often a press; rear hub assemblies bolt on with four bolts. Torque the axle nut and hub bolts to spec, as an under-torqued axle nut will destroy the new bearing quickly. Expect $250-$450 per corner installed at an independent shop.
On the 2010-2024 Kia Forte, sunroof-equipped Fortes route water from the sunroof tray through four small rubber drain hoses down the A- and C-pillars. Pollen, pine needles, and road grit pack the upper end of the hose; once blocked, the tray overflows past the seal and water runs down inside the A-pillar into the front passenger carpet, or out of the rear drains into the trunk/spare-tire well. Owners report soaked front and rear passenger carpet, a musty smell, fogged windows, and in some cases corroded connectors or a wet body control module under the carpet. On earlier TD cars the sunroof surround rubber also cracks and the rear gutter tubes can pull loose from the tray entirely.
Common Symptoms
Wet or soaked front passenger floor carpet
Water in the trunk or spare tire well
Musty/mildew smell in cabin
Windows fogging up persistently
Dripping from the headliner or A-pillar during rain or a car wash
How to Fix
Open the sunroof, locate the two front drain holes in the corners of the tray, and clear them by feeding a length of weed-trimmer line (not wire or coat hanger, which punctures the hose) gently down the tube, then flush with a small amount of water to confirm flow at the outlet behind the front wheel well. Never blast compressed air up the drain - it drives the debris further up and can blow a hose off its nipple, which then requires removing the headliner and A/B/C-pillar trim to reattach. Also check that the rear gutter tubes are still seated on the tray. Dry the carpet and jute padding completely (pull the sill trim and lift the carpet) to prevent mold and corrosion, and clean the drains annually if parking under trees.
On the 2010-2023 Kia Forte, the EVAP purge control solenoid on the Forte's intake sticks or leaks in the open position, so fuel vapor from the charcoal canister is pulled into the intake manifold when it should be sealed - including with the engine off and immediately after a fill-up. The classic owner symptom is a car that cranks a long time or needs several attempts to start only right after filling the tank (the intake is flooded with vapor, giving an over-rich start), then runs fine. The PCM later sets P0441 (incorrect purge flow) or P0496 (purge flow during non-purge condition). Secondary effects include a rough idle right after start-up and, if the canister has been saturated with liquid fuel from repeated overfilling, a plugged canister that damages the replacement valve.
Extended cranking or no-start immediately after filling the gas tank
Rough idle for the first 30 seconds after start
Check engine light
Fuel smell near the engine bay
Failed EVAP readiness monitor
How to Fix
Replace the canister purge control solenoid valve - it is a straightforward job: release the two hose clamps, unplug the connector, and swap the valve. Before replacing, check the vacuum lines to and from the valve for cracks, kinks, or a disconnected hose, and check whether the charcoal canister is saturated with liquid fuel (a saturated canister must be replaced or the new valve will fail again). Stop topping off the tank past the first pump click, since overfilling is what floods the canister. After the repair, clear codes and run an EVAP monitor drive cycle to confirm readiness.
On the 2011-2018 Kia Forte, the factory clear coat delaminates and peels away in sheets, most commonly on Snow White Pearl / Clear White and other light colors and on horizontal panels (hood, roof, trunk) plus mirrors and door handles. Owners attribute it to a too-thin clear coat with inadequate UV protection; a paint chip lets water wick under the clear coat, which then spreads. Kia customer service has acknowledged the issue on 2011-2014 cars; sometimes covered as goodwill despite no formal recall.
Common Symptoms
Clear coat peeling/flaking off panels
White cloudy patches before peeling
Bare/faded paint on hood and roof
Spreading from a small chip
How to Fix
Affected panels must be sanded and repainted/re-cleared; whole-car respray in severe cases. Some owners obtain partial or full goodwill assistance from Kia depending on VIN, paint code, and mileage; filing an NHTSA complaint helps document the defect.
