POWER TRAIN, ELECTRICAL SYSTEM, ENGINE
Power completely dropped while driving in traffic. This occurred several times. I could have easily been rear ended. Also, I could have been stuck within an intersection, I could have been broadsided. I see researched this issue and found it was widely written about in KIA EV6 online forums. Kia should have checked for issues before I leased the 2025 EV and informed me before I made a decision to lease vehicle. This occured in first weeks I drove the new car.

FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
On several occasions, when traveling over 55mph, once the battery hits a certain threshold (35% or 55% so far) the “power is limited” warning will appear on the dash and the vehicle will lose power. This has not occurred at lower speeds but only at higher speeds, and not every time. This vehicle was purchased so my husband could do his freeway commute, but it is on a remote highway where there is often no shoulder, so it especially dangerous to suddenly lose power with limited ability to safely pull over. On one such occasion, he drove the vehicle straight to Kia for inspection. They said the soonest available appointment was in 2 weeks and because they had no technicians available, they could not run the diagnostic that would allow us to get a rental car in the meantime. They suggested going to a different Kia dealership. We called ahead and they said they could try to see it that day or the next, but when we arrived (with, again, the power failing on the drive to the next dealership), they said we were misinformed and they would have to hold the vehicle for at least a week with no rental option. We have since been unable to use the vehicle for commuting due to its unreliability and incredibly dangerous power failure.

SERVICE BRAKES, UNKNOWN OR OTHER
Brakes failed with unintened acceleration. We were stopped behind a truck at a stoplight when the the vehicle accelerated with a foot on the brake. We had it towed from the scene of the accident to our local dealership for testing. They had the vehicle for 4 weeks. Kia customer care was not responsive to our calls and emails or the dealerships. The dealership could not confirm the cause without their cooperation. The police were called to the scene of the accident and there is a report. The vehicle has been looked over by the service department at our local Kia lot. It was appraised for cost of damages by the collision center.

TIRES:SIDEWALL
I was driving my Kia EV6 2023 on I-110 in California when the driver rear tire suffered an instantaneous deflation. I was driving at or slightly below the 65mph speed limit, there was traffic in front and to the rear of me, the road surface was excellent. The tires had 11556 miles of use and were operating at the correct pressures as the vehicle has a tire monitoring system. The ambient air temperature was circa 76F. I was able to exit the freeway with some difficulty. The tire was a Continental Cross Contact 255-45 R20. I have been driving for nearly 60 years, had a wide range of cars and tires and never experienced an incident like that described which has all the indications of a product defect.

ELECTRICAL SYSTEM
The 12-volt battery has failed twice and was ultimately replaced. Additionally, the ICCU unit was replaced once. The vehicle has now returned to the shop for the same recurring issue, as the 12-volt battery either fails to hold a charge or is not charging properly. Most concerning, the vehicle stalled while in motion, creating a serious safety hazard, as it was not possible to activate the hazard lights, leaving occupants in a potentially dangerous situation.

ELECTRICAL SYSTEM
Multiple times the 12V battery has died without warning. Once in driveway while engine was charged to 93%, once while parked at work parking lot at charging station. Both times the car had to be jumped by AAA and driven to the dealership where it sat for 7 days each time with NO diagnosis, no loaner, no rental, and no transport. Finally after the second time, the dealership replaced the 12V battery but still did not give any diagnosis whether this was the ICCU or not. I have complained to KIA Motor Corporation who have advanced my complaint however they have eventually dismissed my complaint. They cannot answer me whether they believe this car is safe. They cannot stand by the safety of this car. They have not acknowledged that this is a safety problem and that other motorists have had similar battery failures while driving on the highway and in other unsafe areas.

UNKNOWN OR OTHER
There is a safety issue with the specific implementation of the regenerative braking system when the car is put into reverse that I have experienced on several occasions. This is not a failure or malfunction of the system as it is working as intended nor are there any warning messages or alerts to signify a defect. The way Kia's system works is that regenerative braking is always on (like all EVs), but at a level you set from 1-4, with 4 being the most aggressive. I leave it on level 4(i-pedal) because I prefer one-pedal driving which I find to be more comfortable and safer. When the car is parked, or at a complete stop, if I put the car into reverse then the regenerative braking level is forced down to level 3. This creates a novel situation where regenerative braking is holding the parked car in place, but also the car won't move until the acceleration pedal is pressed. So I need to tap the accelerator then quickly move my foot to the brake pedal to stop the car which takes a couple of seconds. This causes the car to lurch backwards quickly until my foot reaches the brake pedal because Level 3 is not aggressive enough to bring the car to a complete stop in a short distance. Once I have held down the brakde pedal I can use that to slowly reverse more safely. I haven't hit anyone or anything yet, but I have had a few close calls from cars or pedestrians suddenly appearing from outside my view range at the same time I'm doing that initial reverse lurch. If someone were slower than me or have some physical hindrance that didn't allow them to move their foot quickly then it would be more likely the car may accidentally reverse into a person or car before the driver could respond. Being that regenerative braking is still engaged while reversing it should be a simple software change to allow for level 4 to be enabled thus eliminating the initial reverse lurch issue.

Got error message "Check Electrical vehicle system" when I was driving on 06/03/2025. After driving few miles, then get other error message on dash - "Stop Vehicle and check power supply". After restarted the car, drove few miles and got the error message again. Luckily I got back home with my kids safely. When the tow truck came to take my car to dealership next morning 06/04/2025, the car started, but it died on the middle of the road when trying to drive up the tow truck. The tow truck had to drag my car up instead. If the car suddenly died in middle of highway on 6/3, it would be different story. After almost a week in the Kia shop, It was ICCU assembly and fuse issue on Kia Ev6 and they had to replace it on 06/07/2025 and the car was fixed and picked up on Monday 6/9/2025

had 3 recalls on ICCU module, each time dealer said everything was OK. Last "repair" was in January. In April, car just "died" nothing worked, could not shift, no acceleration and limited braking, had to call a tow truck to move it as everything was locked up. dealer said ICCU shorted out, 3 week repair time, and this is down from 3 month repair time 2 weeks ago. The only warning we had was a dash message to check electrical system, meanwhile Kia app for car said everything was OK, no problems with any thing. dealer listed faults as, P1A9096 dc converter sensor fault, P1E3716 battery charger V2L low voltage, other low voltage comm codes as well but not listed

I am reporting a failure of the ICCU (Integrated Charging Control Unit) in my 2022 Kia EV6. The vehicle became inoperable within weeks of purchase and has remained at a Kia dealership for over six weeks. The failure caused the vehicle to suddenly lose power and become undriveable, which is a serious safety concern. This issue appears to be widespread among EV6 owners. Despite the issue being covered under warranty, Kia has not provided an acceptable resolution. I believe this failure presents a risk of sudden vehicle disablement and should be investigated for safety-related recall potential.

Attempts to charge with home level 2 charger were unsuccessful, both at home and at a public charger. Reduced the charging speed using the car’s settings without success. Dealer reports a failure of the ICCU requiring replacement. This is apparently the subject of a class action lawsuit.

STRUCTURE:BODY
The trunk continues to rattle after multiple trips to the dealership, it has been verified to not be the license plate or any loose components by the dealership. The noise sounds like the trunk latch striking repeatedly during regular driving. The sister model Hyundai Ioniq-5 has had numerous TSBs to fix this issue while Kia EV6 has had none published. And example of the TSB listed is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
