Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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“I'm not sure which component caused the issue, but this happened a couple of times already, when I stepped on the accelerator pedal, but the vehicle didn't response at all. The first time, when I was turning into a parking lot, I had to let off the gas pedal, and try it again. …”
NHTSA complaint #11640771, filed 2025-02“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“The Kia Carnival Hybrid wouldn't allow me to accelerate, topping out at 30/31 MPH despite me fully pressing down on the accelerator. It has happened twice now (a few days apart) and can only be resolved by turning the car off and then back on. Compared to similar complaints logged on the NHTSA website, the difference is that this happened when it was roughly 50-60 degrees outside--not during extremely low temperatures as the other examples have described.”
NHTSA complaint #11659865, filed 2025-05“Today I had an issue with my 2025 Kia Carnival Hybrid SX Prestige where it would not allow me to accelerate past 31 mph. I was on an on-ramp to the highway with my baby in the car and I was flooring the gas, yet it still would not go past 31 mph. I put on my hazards and pulled off, and checked that the max speed setting was not on. I even tried setting the max speed to something higher like 50 mph, and the screen confirmed this, but the car still did not go past 31 mph. …”
