“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. This is the 4th time this has happened in a couple of months since we bought the car.”

NHTSA complaint #11688400, filed 2025-09

“The vehicle(2025 Kia Carnival HEV) is brand new, just over one month old. We parked it in the garage, and after just 4 days of not driving, the battery was totally dead. We were not able to start the van. The battery was 4.5v when measured with a digital volt meter.”

“2025 KIA Carnival Hybrid gets stuck in electric mode. This cause rapid draining of the electric vehicle battery, reduced maximum speed, and reduced acceleration. This has occurred while merging onto the highway. I had to pull over to the highway on ramp shoulder, turn the vehicle off and back, and then merge back until the highway. I have a video of it happening while picking up my kids from school, but it is too large to upload here.”

“My vehicle keeps throwing a code “check hybrid system” and slowing me down to 30mph, it will not accelerate. This is extremely dangerous. I can restart the car and it’s fine but this is a major safety issue considering it keeps happening”

NHTSA complaint #11762493, filed 2026-09

“My 2025 Kia Carnival Hybrid is experiencing repeated electrical and hybrid battery failures. The battery has died multiple times, and the vehicle has shut off while driving, including at higher speeds. When the vehicle shuts off, all electrical systems reset, warning lights flash, and the dashboard displays “User Authorization” notifications. This creates a serious safety hazard for me and my passengers. The defect has occurred multiple times and remains unresolved despite dealer visits. …”
