NHTSA recall 21V519000 (Kia SC214) covers certain 2021 Sorento vehicles with the 2.5L turbocharged engine. Fuel can leak at the pipe connection between the high-pressure fuel pump and fuel rail, increasing fire risk. Severity: high.

What is the 2011-2014 Kia Sorento HECU Electrical Short and Engine Compartment Fire Risk?

NHTSA recall 23V652000 (Kia SC284) covers 2011-2014 Sorento vehicles. The Hydraulic Electronic Control Unit can experience an electrical short and cause an engine-compartment fire while parked or driving. Severity: high.

What is the 2011-2020 Kia Sorento AWD Coupling Failure and Grinding Noise?

The electronically-controlled AWD coupling (transfer case) in Sorentos fails due to worn clutch packs inside the coupling unit. The coupling is responsible for distributing torque to the rear wheels and uses a multi-plate clutch actuated by an electric motor. When the clutch pack… Repairs typically run $800-$2,500. Severity: high.

What is the 2024-2025 Kia Sorento Loss of Low-Beam Headlights and Taillights from BDC Software Fault?

NHTSA recall 25V006000 (Kia SC331) covers 2024-2025 Sorento and specified 2025 hybrid variants. A Body Domain Control Unit software error can cause loss of the low-beam headlights and taillights, reducing visibility and violating FMVSS 108. Severity: high.

What is the 2021-2023 Kia Sorento HVAC Blower Motor Resistor Harness Overheating and Fire (Fan Speed 3)?

On 4th-generation Sorento LX models the wiring harness between the blower motor resistor and its connector was built by supplier Aptiv with thinner-than-spec wire on terminal #2, the circuit that powers blower fan speed 3. With the ignition on and the HVAC fan set to speed 3, tha… Repairs typically run $0-$400. Severity: high.

What is the 2011-2016 Kia Sorento Premature Catalytic Converter Failure (2.4L GDI)?

The 2.4L GDI Sorento (2011-2016) experiences premature catalytic converter failure, often linked to the Theta II oil consumption issue. Excess oil burning fouls the catalytic converter substrate, causing it to overheat and break down internally. Symptoms include a sulfur smell, r… Repairs typically run $400-$2,000. Severity: medium.

What is the 2011-2020 Kia Sorento P0011 — Intake Cam Timing Over-Advanced (Bank 1) from a Failed/Sludged Oil Control Valve?

P0011 indicates the Bank 1 intake camshaft is over-advanced — the CVVT phaser is stuck or the ECM cannot control it. On the Sorento's Theta II 2.4L GDI (and Lambda V6), the overwhelming cause is a failing intake-side Oil Control Valve (OCV/VVT solenoid) that sticks open or closed… Repairs typically run $150-$450. Severity: medium.

What is the 2015-2023 Kia Sorento Oil Pan Gasket Leak (3.3L V6)?

The 3.3L Lambda II V6 engine in the Sorento develops oil pan gasket leaks, typically after 60,000-80,000 miles. The gasket material hardens and shrinks over time due to heat cycling, allowing oil to seep from the oil pan-to-block mating surface. The leak is slow initially but wor… Repairs typically run $300-$800. Severity: medium.

What is the 2011-2020 Kia Sorento P0430 — Catalyst Efficiency Below Threshold (Bank 2) on the Lambda V6, Failed Cat or Rear O2 Sensor?

P0430 only applies to the V6 Sorento, since Bank 2 (the cylinder bank containing cylinders 2-4-6) exists solely on the 3.3L and 3.5L Lambda II V6 (2011-2020). The ECM sees the upstream and downstream oxygen-sensor signals tracking too closely on that bank, meaning the rear (post-… Repairs typically run $250-$2,500. Severity: medium.

What is the 2011-2020 Kia Sorento P0302 — Cylinder 2 Misfire from Ignition Coil, Spark Plug, or GDI Carbon Buildup?

P0302 is a Cylinder 2-specific misfire on the Sorento. As with the other single-cylinder codes, the top causes are a failing cylinder-2 ignition coil and a worn spark plug, but on the Theta II GDI engine a distinctive contributor is carbon buildup on the intake valves — because d… Repairs typically run $150-$600. Severity: medium.

What is the 2016-2023 Kia Sorento Rear A/C Evaporator Refrigerant Leak?

The rear A/C evaporator in Sorentos with dual-zone or tri-zone climate control develops refrigerant leaks due to corrosion of the aluminum evaporator core. The rear evaporator is located under the second-row seats or in the rear quarter panel, making it expensive to access. The l… Repairs typically run $800-$2,000. Severity: medium.

What is the 2011-2020 Kia Sorento P0301 — Cylinder 1 Misfire from a Failed Ignition Coil or Fouled Spark Plug?

P0301 is a dedicated Cylinder 1 misfire on the Sorento. The most common causes, in order, are a worn/fouled spark plug and a failing ignition coil at cylinder 1 (each Theta II GDI cylinder has its own coil-on-plug). A clogged or leaking fuel injector on cylinder 1 is next — frequ… Repairs typically run $150-$400. Severity: medium.

What is the 2011-2020 Kia Sorento P0303 — Cylinder 3 Misfire from a Failed Ignition Coil (Most Common) or GDI Carbon/Plug Wear?

P0303 is a Cylinder 3-specific misfire on the Sorento, and the cylinder-3 ignition coil is the single most common cause — it sits directly on the plug and fails from internal shorts, cracked housing, or worn terminals. Worn spark plugs with widened gaps and GDI intake-valve carbo… Repairs typically run $150-$600. Severity: medium.

What is the 2016-2020 Kia Sorento Steering Column Intermediate Shaft Clunk?

The 3rd generation Sorento (2016-2020) develops a noticeable clunking or popping sound from the steering column when turning at low speeds, particularly over bumps or during parking maneuvers. The issue originates from the intermediate steering shaft universal joint losing its lu… Repairs typically run $200-$650. Severity: low.

What is the 2016-2025 Kia Sorento Panoramic Sunroof Rattle and Wind Noise?

The panoramic sunroof on 2016+ Sorentos develops a persistent rattling noise, especially at highway speeds or on rough roads. The sunroof glass panel vibrates against its frame due to deteriorating seal material and insufficient dampening. Wind noise also increases as the seals l… Repairs typically run $50-$800. Severity: low.
