2025 Kia Carnival Service and Repair Manual

The 2025 model year brought the Carnival its mid-cycle refresh, a reworked cabin with twin 12.3-inch displays and, for the first time, a turbocharged 1.6-liter hybrid alongside the 3.5-liter V6. The hybrid is offered from the LXS up to the SX Prestige, while the V6 covers all five trims from the LX. With two very different powertrains now sharing one body, cooling, high-voltage and transmission specifications differ sharply from car to car, so this factory service and repair manual gives the procedures, torque values, wiring diagrams, diagnostics and maintenance schedules written for the 2025 Carnival you are actually working on.

Known issues on the 2025 Carnival. One recall is on federal record for this model year: on certain 2022-2026 Carnival vehicles, fuel may leak at the pipe connection between the fuel pipe and the fuel rail, and a fuel leak increases the risk of a fire. Owners have filed 124 complaints for the year, most often citing the electrical system, engine and fuel/propulsion system. This service and repair manual carries the factory fuel-rail connection, electrical diagnostic and engine procedures behind each of those areas.
