2024 Kia EV6

Driving with my wife and [XXX] child, there was a pop sound from under the car, and the car suddenly showed multiple faults, including "Check electric vehicle system”, which cleared on their own. I parked and turned the car off and on again and the faults reappeared. I started driving home, and during the drive it showed "Stop vehicle and check power supply" and audibly alarmed. As I was only half a mile from my house on local quiet roads, I made it. A few minutes later, I tried to turn on the car and some displays were off, there was no drive power, the steering wheel did not turn, the door locks were flakey, and I wasn't able to tell if I had shifted into Park or if the parking brake was engaged. When the tow truck arrived, the car was completely unresponsive and there was no way to release the parking brake or shift the car in neutral, so the car was dragged across the pavement and onto the tow truck. The failure was quick and comprehensive and could have easily caused injury. There are many highways near me with fast, busy traffic and either no emergency shoulder or a very narrow one. If my car tells me that I need to stop the vehicle, that can create a very dangerous choice between stopping somewhere less safe quickly or risking the car being completely disabled while in the travel lane while I look for a safer spot. Loss of cabin heat can easily become dangerous very quickly in the winter. Many drivers may not even understand the urgency of the warning until the car starts failing to drive. The car is at a Kia dealership for repair who confirmed an ICCU failure. See related NHTSA recall no 24V-867 and others. ICCU failures are endemic to Kia and Hyundai EVs. ICCU failures are widely discussed on many internet forums and seem much more common than the 1% failure rate claimed by Hyundai/Kia. FYI, an interesting root cause analysis was shared on a German EV forum: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

About 10 miles from home a warning saying to check the electrical system came on the dash and the car would not go faster than about 25 miles per hour. We had to limp back home, turning the car off every few miles as it would start aggressively beeping to turn off the car. After getting it towed to the dealership, it took them several weeks to determine it was the ICCU and fuse, and I did not take possession of my car back for nearly 8 weeks. While this was under warranty, I am still currently waiting for reimbursement on the tow to the dealer and the rental I had to get for 3 days before the dealer could get me a loaner.

Whike driving down the street, the car lost power despite being charged to 95%. An alert went off on screen stating an electric system issue and then stopped in the middle of the road. Between the warning showing up, and car losing full power was less than a minute. There was no opportunity to pull over safely and the car was stuck in the middle of the street until a tow truck was able to come. Police had to direct traffic as it was blocking the only lane on a busy street.

I have a 2024 Kia EV6 I took my car in for an unrelated repair. Tech found an airbag code that I asked to be investigated. The airbag wiring harness was damaged and needed replacement. The repair was quoted as $6600. The dealer claimed that this was from rodent damage but the photo evidence does not look like rodent damage. It looks like the wire was pulled out of the harness. Of note, the 2024 Kia Niro and 2024 Kia Telluride have similar active recalls. Please see NHTSA Recalls 25V-024 and 23V-035.

Car suddenly slowed from 55 mph to 25 mph because of issues with the 12v battery and the ICCU system. The car is only 1 year old. From looking online, this seems to be a fairly common issue/problem. The dealer is working on it now, but it seems likely that this issue will happen again. If it happens on a freeway, certainly a safety concern.
