In owners’ own words

Source: NHTSA complaint database

Filed with NHTSA by the people who own these cars, about the electrical system. 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
Electrical System Feb 22, 2026 NHTSA owner report
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.
Electrical System Feb 18, 2026 NHTSA owner report
While driving around, the van will go into "limp mode" effecting my speed and acceleration. Then the battery will become drained and the car alarms me to "Check Hybrid System. Stop safely." It seems the hybrid system fails to switch from battery to engine when the battery gets too low, creating the alert.
Electrical System Dec 15, 2025 NHTSA owner report
The car gave alert of "hybrid system failure" and showed a picture of a drained battery. After about 20 seconds, we were unable to drive over 30 mph. After about 30 more seconds, the car shut off and had to be jumped to work again. Luckily we were pulling over into a parking lot when it shut off, but were blocking the entrance.

Common questions

Source: NHTSA complaint database, recalls and manufacturer communications

Are electrical problems common on the 2025 Kia Carnival?

They are documented: NHTSA holds 104 owner complaints naming the electrical system on this model year (55% of everything owners filed about it), and 37 manufacturer bulletins are filed under the same heading. Whether it is a problem on one particular car is a diagnosis, not a count, and a count says nothing about how many were sold.

Is there a recall for the electrical system on the 2025 Kia Carnival?

No recall campaign is filed under this heading for this model year (there are 1 filed under other headings). A bulletin is not a recall: it carries no federal duty to repair for free.

When do electrical problems show up on the 2025 Kia Carnival?

Too few of the complaints carry an odometer reading to say. The model year's page shows the mileage curve across every system where it can.

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.
