What is the 2011-2019 Kia Sorento Theta II Engine Bearing Failure and Seizure?
The Theta II 2.4L and 2.0T GDI engines in 2011-2019 Sorentos can experience catastrophic engine seizure due to machining debris left in the crankshaft oil passages during manufacturing. Metal shavings restrict oil flow to rod and main bearings, causing premature bearing wear and… Repairs typically run $0-$7,500. Severity: high.
What is the 2011-2014 Kia Sorento HECU Electrical Short and Engine Compartment Fire Risk?
The Hydraulic Electronic Control Unit (HECU) in the ABS module can develop an internal electrical short circuit, causing the unit to overheat and potentially ignite an engine compartment fire even while the vehicle is parked. NHTSA Recall 19V-085 covers over 70,000 Sorentos. Kia… Repairs typically run $0-$1,200. 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 2011-2020 Kia Sorento P0300 — Random/Multiple Misfire from Theta II GDI Ignition Coils, Carbon Buildup, or Low Oil / CVVT Starvation?
On the Kia Sorento, a P0300 random/multiple-cylinder misfire most often appears on the 2.4L Theta II GDI four-cylinder (G4KE/G4KJ) and 2.0T, typically in the 2011-2020 XM/UM generations. Because GDI does not wash fuel over the intake valves, carbon accumulates and disturbs airflo… Repairs typically run $150-$600. Severity: high.
What is the 2011-2020 Kia Sorento P0016 — Crank/Cam Correlation (Bank 1) from Clogged OCV, Stretched Timing Chain, or Low Oil?
P0016 means the crankshaft and Bank 1 camshaft positions no longer line up within spec. On the Sorento's Theta II 2.4L GDI and Lambda V6 (2011-2020), the leading causes are a failing/clogged CVVT Oil Control Valve (OCV) and, on higher-mileage engines, a stretched timing chain or… Repairs typically run $150-$1,500. 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 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 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 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 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 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 2011-2020 Kia Sorento P0442 — Small EVAP Leak from Loose Gas Cap or Failing Purge Control Solenoid Valve?
P0442 signals a small evaporative-emissions leak on the Sorento. The single most common cause is a loose, worn, or poorly-sealing fuel (gas) cap. The next most common Sorento-specific culprit is the vapor canister Purge Control Solenoid Valve (PCSV), which lets fuel vapor pass fr… Repairs typically run $30-$400. Severity: low.
What is the 2011-2020 Kia Sorento P0455 — Gross EVAP Leak from Gas Cap, Purge Solenoid, or Canister Close Valve?
P0455 is a large/gross EVAP leak on the Sorento — a much bigger opening than P0442. On the 2012-2015 XM Sorento the most common cause is again a loose or faulty gas cap, but when the cap checks out the two prime suspects are the Purge Control Solenoid Valve (PCSV) in the engine b… Repairs typically run $30-$500. Severity: low.
