The Kia Sorento III, particularly the facelifted version introduced in 2018, represented a significant step forward for the Korean automaker in the highly competitive mid-size SUV segment. This iteration of the Sorento, produced from 2018 to 2020, offered a compelling blend of practicality, comfort, and technology. Among the various engine and drivetrain configurations available, the 2.4 GDI (Gasoline Direct Injection) paired with a 6-speed automatic transmission and seven-seat capability was a popular choice, especially in markets where larger engines were less favored due to taxation or fuel economy concerns. This variant aimed to provide a balance between performance and efficiency for families seeking a versatile SUV.

INTRODUCTION
The 2018-2020 Kia Sorento facelift built upon the success of the third-generation Sorento (UM), which debuted in 2014. The facelift brought revised styling, updated technology, and refinements to the powertrain options. The 2.4 GDI automatic, with its seven-seat configuration, was positioned as a mid-range offering, slotting below the more powerful 3.3L V6 and above the base 2.0L engine. It was designed to appeal to buyers prioritizing fuel efficiency and practicality without sacrificing the space and versatility of a three-row SUV. The Sorento, in general, was a key model for Kia, helping to establish the brand as a serious contender in the global automotive market, particularly in North America and Europe.
Powertrain & Engine Architecture
At the heart of this Sorento variant lies the G4KJ 2.4-liter inline-four cylinder engine. This engine utilizes Gasoline Direct Injection (GDI) technology, where fuel is injected directly into the combustion chamber, improving efficiency and power output compared to traditional port fuel injection. The G4KJ engine produces 188 horsepower at 6000 rpm and 241 Nm (177.75 lb-ft) of torque at 4000 rpm. It features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing airflow for enhanced performance. The engine’s 11.3:1 compression ratio further contributes to its efficiency. Paired with this engine is a 6-speed automatic transmission, providing smooth and responsive gear changes. This transmission was chosen for its balance of efficiency and drivability, offering a comfortable driving experience for everyday use.
Driving Characteristics
The 2.4 GDI automatic Sorento delivers a comfortable and composed driving experience. While not particularly sporty, the engine provides adequate power for everyday driving situations, including highway merging and overtaking. Acceleration from 0 to 60 mph takes approximately 9.7 seconds, and 0-100 km/h in 10.2 seconds. The automatic transmission is well-tuned, offering smooth shifts and a predictable response. Compared to the more powerful V6 engine, the 2.4 GDI feels less urgent in its acceleration, but it offers significantly better fuel economy. The six-speed automatic transmission’s gear ratios are optimized for both fuel efficiency and reasonable performance. The front-wheel-drive configuration contributes to a slightly more fuel-efficient driving experience, although all-wheel drive was available as an option.
Equipment & Trim Levels
The 2.4 GDI automatic Sorento typically came standard with a respectable array of features. These included air conditioning, power windows and locks, a touchscreen infotainment system with Bluetooth connectivity, a rearview camera, and basic safety features like ABS and stability control. Higher trim levels added features such as leather upholstery, heated front seats, a panoramic sunroof, a premium audio system, and advanced safety technologies like blind-spot monitoring and lane departure warning. Interior upholstery was typically cloth on the base trims, with leather options available on higher-spec models. Dashboard configuration was generally consistent across trims, with a focus on user-friendliness and practicality.
Chassis & Braking
The Sorento III utilizes a McPherson strut front suspension and a multi-link rear suspension, providing a comfortable ride and predictable handling. The suspension is tuned to prioritize comfort over outright sportiness, making it well-suited for long journeys and everyday driving. The braking system consists of ventilated discs at the front and solid discs at the rear, providing adequate stopping power. ABS (Anti-lock Braking System) is standard, enhancing safety during emergency braking situations. The vehicle’s weight of approximately 1804 kg (3977.14 lbs) influences its handling characteristics, requiring a slightly more deliberate steering input compared to lighter vehicles.
Market Reception & Comparison
The 2.4 GDI automatic Sorento was generally well-received by critics and consumers alike. It was praised for its spacious interior, comfortable ride, and good value for money. Fuel economy was a key selling point, with the 2.4L engine offering a noticeable improvement over the V6. Compared to competitors like the Honda Pilot and Toyota Highlander, the Sorento offered a more affordable price point and a longer warranty. However, some critics noted that the 2.4L engine could feel underpowered when fully loaded with passengers and cargo. The 1.6L Turbo Diesel and 3.3L V6 were the other engine options, offering different performance and fuel economy characteristics. The diesel was favored in Europe for its efficiency, while the V6 appealed to those prioritizing power.
Legacy
The Kia Sorento III, and specifically the 2.4 GDI automatic variant, has proven to be a relatively reliable vehicle in the used car market. The G4KJ engine is generally considered durable, although regular maintenance, including oil changes and timing chain inspections, is crucial. The 6-speed automatic transmission has also proven to be fairly robust. Common issues reported by owners include occasional problems with the infotainment system and minor trim wear. Overall, the 2018-2020 Sorento 2.4 GDI automatic remains a popular choice for families seeking a practical, affordable, and reliable SUV.
