Kia Carnival electrical problems, 2022–2027

168 of the 497 complaints owners filed with NHTSA about the Kia Carnival 2022–2027 name the electrical system (NHTSA’s “Electrical System” heading — wiring, modules, batteries, charging, infotainment and driver displays — NHTSA's broadest heading). The loudest years: 2025 (104), 2022 (24), 2026 (18). Filed under the same heading across these years: 6 manufacturer bulletins, 1 recall campaign. Every figure is a linked federal record; none is a failure rate, none a repair cost, and none a verdict on one car.

One row per model year on file, newest first. A year marked in depth has its own page: the complaints, the owners’ words and every document under this heading for that year.

Two things the counts carry that are not the car: how many of each year were sold, and how long each has been on the road — an older year out-counts a newer one before anything is wrong with it. The share column is the honest comparison across years: what part of that year’s complaints named the electrical system. Nothing here is a rate.

In owners’ own words

Source: NHTSA complaint database

Filed with NHTSA by the people who own these cars, about the electrical system, from the model years with the most to say. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.

The vehicle shows a Driver Assistance System Warning randomly. Then the vehicle is unable to accelerate past ~30MPH. We almost got hit when this happened. The warning does not show up in notifications nor does it show up in diagnostics. It gets reverts back to normal when the vehicle is turned off then turned back on. It seems to reset

While driving the car it will stick in the electric mode and not go back into gas mode. You will only be able to go up to 30-35 miles an hour and in order to fix this issue as of right now all I could do was have to pull over to the side of the road put the car in park turn it off and turn it back on.

En lo que vade compra me ha dañado 2 baterías las que he tenido que comprar. También daño la bomba de la gasolina. Tuve que pagar la limpieza de las líneas. Casi alrededor de $ 1,000.00 dólares he tenido que pagar de mi bolsillo para un vehículo que lo tengo desde nuevo y que aún pago.

Sometimes my passenger side door will slam shut if I am parked on the hill and the sliding door lock is on, I have noticed that it only slams shut if that lock is on. If the lock is not on, it closes on its own without pressing the door close button on the door, on the driver side, or on the key fob. It will close quickly and not normal

2026 Kia Carnival Hybrid SX. The digital instrument cluster intermittently flickers, goes blank, and displays “NO SIGNAL” while driving, potentially causing loss of access to speed, gauges, warning indicators, and other safety information. The failures occur unpredictably.

Which Kia Carnival years have the most electrical complaints?

2025, 104; 2022, 24; 2026, 18. Raw counts, and an older year has had longer to collect them; by share of each year's own complaints the loudest is the 2025 (55%).

Is there a recall for the electrical system on the Kia Carnival?

Yes — one campaign is filed under this heading across these model years: 26V046000 (2026). A recall is matched by VIN, and applies to specific years; check yours at nhtsa.gov/recalls.

When do electrical problems show up on the Kia Carnival?

Too few of the complaints carry an odometer reading to say.

What does NHTSA's "Electrical System" heading cover?

Wiring, modules, batteries, charging, infotainment and driver displays — NHTSA's broadest heading. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
