Complaints about the 2022 Kia Carnival cluster most heavily around structural issues and the electrical system. The structural category draws the most reports, with owners describing problems related to doors and body components, most notably the powered sliding doors behaving unexpectedly, including opening on their own when the key fob is in range. Electrical system complaints cover a range of symptoms: warning lights cycling on and off, telematics and navigation system failures, and engine codes that return after being cleared at the dealership. A smaller but consistent group of visibility and wiper complaints rounds out the picture. Several owners also describe engine-related symptoms, misfires, loss of power, and the vehicle entering a reduced-power mode, though these span complaint categories. The spontaneous sliding door behavior is a recurring and specific pattern, with owners reporting the door activating without any intentional input from them.

By System
The 2022 Kia Carnival has 11 recalls, the most serious involving multiple fuel system and electrical fire risks, including fuel leaks at the fuel pipe and fuel rail connections and a tow hitch wiring harness that can short circuit and start a fire even while the vehicle is parked.
The tow hitch harness issue appears across two related recalls covering both factory-installed and dealer-accessory harnesses where water or a wiring fault can cause the circuit board to overheat and ignite. Three separate recalls address fuel leaks at different points in the fuel delivery system, any of which can allow fuel to escape near heat sources and raise fire risk.
Several recalls center on the passenger-side power sliding door. The door's latch controller can malfunction and leave the door unlatched, allowing it to swing open while driving. The auto-reverse feature may also fail to activate when the door encounters an obstruction, meaning it can close on a person without stopping. Separately, roof molding on certain vehicles is not properly secured and can detach at speed, creating a hazard for other vehicles on the road.
