The 2nd generation Forte with the Nu 2.0L GDI engine (2014-2018) can develop engine knocking and excessive oil consumption. Similar to the Theta II issues but in the Nu engine family, piston ring wear leads to oil blow-by and cylinder scoring. Kia extended warranty coverage under… Repairs typically run $0-$5,500. Severity: high.
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 t… Repairs typically run $0-$500. Severity: high.
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… Repairs typically run $4,000-$8,000. Severity: high.
On 2016-2018 Forte sedan and Forte Koup (and the related 2018-2019 Rio), repeated high-temperature soak in the trunk area causes a thermal crack to develop in the pawl of the trunk latch assembly. Once the pawl cracks, the glow-in-the-dark interior emergency release handle no lon… Repairs typically run $0-$250. Severity: high.
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… Repairs typically run $120-$400. Severity: high.
The UVO/AVN infotainment head unit hangs during boot on the UVO logo, or the display goes black at random while driving, taking the radio, Bluetooth phone/audio, navigation and the rear-view camera image with it. Some cars recover on the next key cycle or when reverse is selected… Repairs typically run $0-$1,200. Severity: medium.
The YD-generation Forte's conventional six-speed automatic (A6GF1 behind the 1.8/2.0 Nu, A6MF2 behind the 1.6T) wears the aluminium valve-body bores that carry the two pressure-reducing valves and the torque-converter-clutch control valve. As the bores egg out, solenoid feed pres… Repairs typically run $450-$2,200. Severity: medium.
Forte 2.0L Nu cars that consume oil push unburned oil ash through the exhaust, which poisons and eventually plugs the washcoat on the close-coupled (manifold) converter and the underfloor converter. Owners see P0420 catalyst-efficiency-below-threshold, sometimes with a rotten-egg… Repairs typically run $600-$2,500. Severity: medium.
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 in… Repairs typically run $0-$600. Severity: medium.
Owners repeatedly replace low-beam headlight bulbs, sometimes multiple times in a year. The root cause is frequently a failing headlamp socket/pigtail connector that overheats and melts (a high-resistance/loose-connection condition), rather than defective bulbs. Kia issued campai… Repairs typically run $50-$300. Severity: medium.
The star-shaped rubber flexible coupler inside the electric power-steering (MDPS) motor wears prematurely, producing a distinct click, clunk, or knock felt through the steering wheel and column when turning, going over bumps, or maneuvering at low speed. Kia acknowledged the prem… Repairs typically run $150-$600. Severity: medium.
Nu-family Forte engines use a hydraulic timing chain tensioner that depends on oil pressure to keep the chain taut. After the car sits overnight the tensioner bleeds down, and on start-up the slack chain slaps the guides for one to five seconds until oil pressure builds - a loud… Repairs typically run $350-$1,400. Severity: medium.
Manual-transmission Fortes have two linked, well-reported complaints. First, the clutch master and slave cylinders fail early - owners report both replaced together at mileages as low as 45,000 on a 2020 car - producing a soft or sinking pedal, a bite point that walks up and down… Repairs typically run $300-$1,800. Severity: medium.
Forte cooling systems across all three generations lose coolant from two recurring points. The plastic thermostat housing (water outlet) on the Nu engines warps or develops hairline cracks with thermal cycling, leaving a small puddle under the front of the engine that owners desc… Repairs typically run $180-$650. Severity: medium.
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… Repairs typically run $200-$500. Severity: medium.
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-tempe… Repairs typically run $250-$1,600. Severity: medium.
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 protecti… Repairs typically run $500-$2,500. Severity: low.
Forte owners across generations report the heater/AC blower quitting entirely or losing individual speeds, and the cause traced repeatedly on the forums is heat damage at the blower motor's electrical connector rather than the motor itself. Owners describe pulling the connector o… Repairs typically run $60-$450. Severity: low.
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 symp… Repairs typically run $90-$350. Severity: low.
