The dominant complaint pattern for the 2023 Kia Carnival centers on the sliding door structure. Owners frequently report the power sliding doors malfunctioning, most commonly describing the door motor stalling against resistance and the door attempting to reverse direction unexpectedly, sometimes with cable failures behind the door glass. These incidents occur across normal operating conditions, including cold weather. Outside of the door system, a handful of owners report a recurring fuel odor that persists even after dealership service attempts, with at least one case involving a confirmed fuel leak at the injectors. A smaller cluster of complaints mentions steering and brake behavior, including one report of ABS activating on dry pavement without bringing the vehicle to a full stop.

By System
The 2023 Kia Carnival has 4 recalls, the most serious being two separate fire risks: a fuel leak at the connection between the fuel pipe and fuel rail, and an electrical short in the tow hitch harness that can ignite a fire while the vehicle is parked or in motion.
The tow hitch harness issue only affects vehicles equipped with a tow hitch, either as original equipment or a dealer-installed accessory. On the structural side, the power sliding door auto-reverse feature may not activate in every situation, meaning the door can close on a person in its path. The roof molding on certain vehicles can also loosen and shed onto the road, creating a hazard for traffic behind the vehicle.
