“Horn stops working and needs to be replaced within a year or less. I reported the first time my horn stopped working and it took 4 months until I can have an appointment and order the part. The second time it stopped working was within a year and scheduling an appointment was difficult. I was almost in an accident and unable to use to both to alert the other driver.”

NHTSA complaint #11717275, filed 2026-02

“Horn not working. Second time less than 1 year old. First time dealer said it was blown fuse. There are 2 fuses associated with horn shown on diagram. I tested continuity on both and they are good. I believe there is a deeper electrical system issue with this vehicle. Quick forum search indicates this could be a widespread issue.”

“Purchased a 2024 Kia Carnival on Monday, June 2 from a dealership. On Friday, June 6, the battery was dead and I had to have it jumped. I took it to the dealership the next week to have it looked at and they said the battery was fine. A week and a half later, after sitting for two days, the car wouldn't start again. Had it jumped again and took it back to the dealership. They seem to be confused with the issue and said they will need to have the car until the battery dies again so they can see it in real time . A quick Google search indicates that this is by far not an isolated event. …”

“Sliding doors closed on my oldest son’s fingers leaving severe indentation on his pointer, middle and ring fingers. My youngest son has his head dragged inbetween the door and the exterior of the vehicle. I was able to dislodge his head by the base of his neck. My dealership was unhelpful and went as far as to gaslight me into thinking any of this was my fault as a parent. I was shown where the sensor was (a thin strip of garbage) and was told that unless the sensor detects depth it will not stop. I was questioned why my child’s head was on the ground of the car and was judged as a mother. …”

NHTSA complaint #11647905, filed 2025-03

“Driver side passenger back sliding door will not open or close properly. Door will jam and make a loud noise or will not open when trying to open. Took it the dealership 4 times they replaced the motor but the issue continues.”
