2024 Kia Carnival Electrical System

Horns (high and low) have been replaced 5 times under a warranty. This is a serious safety hazard. Vehicle: Kia Carnival (Model Years 2022–2024) Issue: Repeated horn failure / electrical malfunction Owners of 2022–2024 Kia Carnival vehicles are experiencing repeated horn failures that present a safety concern. Reported symptoms include complete loss of horn function, intermittent operation, delayed response, and in some cases random horn or alarm activation without driver input. When the failure occurs, both the high-pitch and low-pitch horns are often found to be inoperative. Many owners report that dealerships replace both horns, sometimes multiple times, with some vehicles requiring second or third replacements. Kia has acknowledged this issue through a Technical Service Bulletin (ELE-263), which instructs dealers to replace both horns when one fails; however, the bulletin does not identify a permanent root cause or corrective design change. As a result, the issue frequently recurs after replacement. A non-functional or intermittent horn significantly reduces the driver’s ability to warn other road users and avoid collisions, creating a clear safety risk. Given the recurring nature of the failure across multiple model years, this appears to be a systemic defect rather than isolated component wear.

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. I simply explained he’s [XXX] and fell as the door was opening to which the door dragged him by his head. Thankfully my children were unharmed physically but emotionally are scarred. It’s not a matter of IF something tragic happens to another family but WHEN. Make the recall and get this garbage van safe for all families who think it’s safe. I tried to recreate a situation where the sensor should stop using a stuffed bear. The door not only struggled to shut making creaking noises but then completely shut on the child sized stuffed animal INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

A/C system on my 2024 Kia Carnival failed twice within weeks. First at 60,100 miles, repaired at dealership for $398. Then again shortly after, leaving vehicle undrivable in summer heat. Kia has done nothing despite having a case number (#25267950). This is a recurring failure that affects safety and comfort during high-temperature seasons. I believe this is a manufacturer defect and request a formal investigation.

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. Something is very wrong with the electrical draw.

Purchased new KIA Carnival in May 2024. In August 2024 ALL of the warning lights came on and started cycling through to check every system. The warnings were the only thing that worked on the instrument cluster. All of the analog instruments stopped working: the speedometer, the tachometer, the fuel gauge, etc.. The blinkers didn't even indicate that they were working. I drove the vehicle directly to the dealership and they could see the problem, but then as quickly as it started it stopped. They said diagnostics did not indicate any problem so they were not able to find the issue to fix it. It started again in February.

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.

Battery randomly died in the car overnight
