TRAILER HITCHES
Kia America, Inc. (Kia) is recalling certain 2016-2022 Sorento, 2021-2022 Sorento Hybrid (HEV), 2022-2023 Sorento Plug-In Hybrid (PHEV), and 2017-2022 Sportage vehicles equipped with a tow hitch harness installed as original equipment, or purchased as an accessory through a Kia dealership. Debris and moisture accumulation on the tow hitch harness module printed circuit board (PCB) may cause an electrical short, which can result in a fire.
BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
Kia America, Inc. (Kia) is recalling certain 2019 Sorento vehicles. Due to a manufacturing error, water may leak into the rearview camera, which can cause the rearview camera image not to appear on the display. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
STEERING:ELECTRIC POWER ASSIST SYSTEM
Kia Motors America (Kia) is recalling certain 2018 Kia Sorento vehicles. The cowl crossbar that connects to the Motor Driven Power Steering (MDPS) steering column may be improperly welded, allowing the steering column to separate.
AIR BAGS:SIDE/WINDOW
Kia Motors America (Kia) is recalling certain 2018 Kia Sorento vehicles. The side curtain air bags on these vehicles have a component that may detach during deployment of the inflatable curtain air bag.
FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS
Kia Motors America (Kia) is recalling certain 2011-2017 Optima, 2012-2017 Sorento and 2011-2018 Sportage vehicles that previously received an engine replacement under recall number 17V-224, warranty, or the Knock Sensor Detection System (KSDS) Product Improvement Campaign. The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned or improperly torqued during the engine replacement procedure, possibly causing a fuel leak.

According to Au7o's analysis of 1,634+ owner reports, the 2012 Kia Sorento has 13 documented issues. The most frequently reported are: Theta II Engine Bearing Failure and Seizure, HECU Electrical Short and Engine Compartment Fire Risk, P0300 — Random/Multiple Misfire from Theta II GDI Ignition Coils, Carbon Buildup, or Low Oil / CVVT Starvation. Of these, 5 are rated critical and should be addressed promptly.
The 2012 Kia Sorento has 13 known issues documented across 1,634+ owner reports. 5 issues are rated critical: Theta II Engine Bearing Failure and Seizure and HECU Electrical Short and Engine Compartment Fire Risk and P0300 — Random/Multiple Misfire from Theta II GDI Ignition Coils, Carbon Buildup, or Low Oil / CVVT Starvation and P0016 — Crank/Cam Correlation (Bank 1) from Clogged OCV, Stretched Timing Chain, or Low Oil and AWD Coupling Failure and Grinding Noise. Prospective buyers should inspect for these issues and factor potential repair costs into their purchase decision. Regular maintenance following the manufacturer's schedule helps prevent many common problems.
Repair costs for known Kia Sorento issues range from $0 to $7,500, depending on the specific problem and whether you choose DIY or professional repair. The most critical issue, Theta II Engine Bearing Failure and Seizure, typically costs $0-$7,500 to repair. Au7o provides step-by-step DIY maintenance guides that can help reduce repair costs.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
