On the 2016-2023 Kia Sorento, 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 leak results in the entire A/C system losing refrigerant, affecting both front and rear cooling. R-1234yf refrigerant used in newer models adds to repair cost.
Diagnose with UV dye and electronic leak detector to confirm rear evaporator as the leak source. Replace the rear evaporator core — this requires removal of interior trim panels and sometimes the second-row seats. Replace the receiver/drier and expansion valve at the same time. Evacuate and recharge the system. Some owners opt to bypass the rear evaporator loop if they do not need rear A/C, which is a less expensive fix.

On the 2015-2023 Kia Sorento 3.3L Lambda II 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 worsens over time. Oil drips onto the exhaust crossover pipe below the engine, creating a burning oil smell and potential fire risk.
Remove the oil pan, clean both mating surfaces thoroughly, and install a new oil pan gasket with Kia-specified RTV sealant at the corners. Some mechanics prefer to use all-RTV (no gasket) for a more durable seal. The job requires supporting the engine and lowering the front subframe on some model years for clearance. Retorque oil pan bolts to spec in the correct sequence.

On the 2016-2025 Kia Sorento, 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 lose their compression over time. In some cases, the sunroof drain tubes clog, leading to water leaks into the headliner.
Clean and lubricate the sunroof tracks and seals with silicone-based lubricant. Apply foam dampening tape to the sunroof frame contact points to eliminate rattle. Clear the sunroof drain tubes by passing a flexible wire or compressed air through the four corner drains. If seals are cracked or compressed, replace the sunroof weatherstrip. Severe cases may require sunroof frame adjustment at the dealer.
