KIA Complaints

The Integrated Charging Control Unit (ICCU) and High Voltage Fuse failed twice within 100 miles, causing a total loss of motive power while driving. The first failure occurred on Jan 24, 2026 (13,954 miles), and the second on Feb 2, 2026 (approx. 14,000 miles), immediately after the first repair attempt. In both instances, the 12V charging system failed, severing connection to the high-voltage battery and forcing the vehicle into a "limp mode" with reduced speed and steering loss in active traffic, creating a severe collision risk. ?The first authorized manufacturer technician stated that the issue was with the 12v battery and not the ICCU, however the second dealership confirmed that the issue was the ICCU all along, resulting in 17 days out of service. Symptoms included a loud "pop" followed by "Check Electric Vehicle System," "Stop Vehicle and Check Power Supply," and 12V battery warnings. Despite Recall SC327/SC302 procedures, the safety defect persists.

The windshield creates layers of frost if it is really cold.. While the above might be unrelated but the other day I was rolling my front passenger window up in the cold weather and the window just shattered - it just exploded, even though it stayed intact it shattered into a thousand pieces

2016 Kia Sorrento Ex paint is coming off in panels and different areas of car. I called KIa and they cant do anything about it

While driving in traffic, my 2024 Kia Seltos suddenly shut down without warning again. I lost propulsion while the vehicle was in motion with passengers inside, creating an immediate safety hazard. The issue appears electrical or powertrain-related. This occurred during normal operation and could result in a serious crash. My vehicle shutting down in active traffic with passengers is unacceptable, and there is no recall remedy in place to correct this hazard. I am requesting a manufacturer-level resolution under Ohio Lemon Law and the Magnuson–Moss Warranty Act.

My wife was slowly pulling into a parking spot at kohls and the car lunged like the gas pedal was pressed all the way down and hit parking pole in spot .

The contact owns a 2023 Kia Carnival. The contact stated that during freezing weather, the button was depressed to open the driver's side rear sliding door, and the door automatically opened; however, the motor reached a point of resistance and attempted to close the sliding door.

The contact paid for the remaining cost of the repair. The manufacturer was contacted about the repair and provided a case number. The vehicle was repaired. The failure mileage was 63,476.

I was driving my car, all of a sudden there was a loud knocking sound. The car suddenly wouldn’t accelerate. I was in the middle of a busy intersection with kids! I am 95 pounds, I can’t push the van! After being hit. I managed to get it moved with help. My van only had 108,000 miles on it! Took it to a mechanic, said needed an engine as there was no oil in it. How is that possible? We just changed it a month prior. It’s out of warranty by 8000 miles so Kia will not do anything! I’m sorry, but there are numerous complaints about this, yet nothing is being done! Now I’m having to pay 5000+ to replace an engine because Kia is just terrible!
