Common problems reported by 2022 Kia K5 owners, with recommended fixes and estimated repair costs.
DCT Transmission Oil Pump Failure and Power Loss
The 8-speed dual-clutch transmission oil pump may fail, causing the vehicle to suddenly lose power. The fail-safe limited-mobility mode may be impaired, resulting in a complete loss of vehicle power while driving. This affects 2021-2023 K5 models with the DCT.
Kia issued a recall for affected K5 models. Dealers will inspect and replace the transmission as necessary and update the TCU software free of charge.
Est. Cost: Covered under recallFuel Tank Expansion and Fire Risk
A damaged check valve can allow air to enter the fuel tank, causing it to expand and contact hot exhaust components, potentially melting the tank and creating a fire risk. Owners may notice a fuel smell or evaporative emissions system warning codes.
Kia issued a recall for affected K5 models. Dealers will replace the check valve and inspect the fuel tank, replacing it if necessary, free of charge.
Est. Cost: Covered under recallHigh-Pressure Fuel Pipe Leak (2.5T)
On K5 models with the 2.5L turbocharged engine, fuel may leak at the pipe connection between the high-pressure fuel pump and fuel rail. A fuel leak near hot engine components increases the risk of fire. Owners may detect a fuel odor after driving.
Kia issued a recall for 2021-2022 K5 2.5T models. Dealers will inspect and tighten or replace the fuel pipe as necessary, free of charge.
Est. Cost: Covered under recallR-MDPS Steering Assist Communication Fault
The Rack-Mounted Motor Driven Power Steering (R-MDPS) system lacks the ability to diagnose communication faults. If a communication fault occurs while driving around a curve with Lane Following Assist engaged, the steering assist level may not adjust properly, causing a sudden increase in steering effort.
Kia issued a recall to update the R-MDPS software to add fault detection capability. Dealers will perform the software update free of charge.
Est. Cost: Covered under recallErratic Shifting and Transmission Hesitation
Some K5 owners report erratic shifting behavior, particularly in Sport and Smart drive modes. Complaints include hard downshifts that jolt the vehicle, hesitation when accelerating from a stop, and the transmission hunting between gears at steady speeds. The issue is more pronounced in the 8-speed DCT.
Kia has released TCU software updates to improve shift logic and reduce harshness. Visit the dealer for the latest calibration. If shifting problems persist after the update, the clutch pack may need inspection or replacement under warranty.
Est. Cost: $0 under warranty; $100 - $200 for software update out of warranty
