2025 Kia EV6 owner complaints

I was driving on the highway when I heard a pop like a loud fuse sound from the back seat area. Suddenly the car dropped 15 mph from 70 mph to 55 mph and the battery and electrical system warning lights came on and the vehicle said check electrical system. I was able to continue with my hazard lights on to exit the highway, at which point the max speed of the vehicle dropped to 45 mph. It would not go faster no matter how hard I pushed the gas pedal. I was able to pull over to a gas station and park in a spot but the vehicle had to be towed. When the tow truck arrived, the vehicle also flashed with the 12V battery low warning. It was diagnosed as a failed ICCU, which rapidly drained the 12V battery. The car is only 4 months old with about 7,300 miles. This is a serious safety concern, espe

Driving down local (residential) roads, the ICCU died; towed to dealership 12/3/2025. All 12 volt electrical was inoperable. So no hazard lights, no shift to neutral, no locking the doors. It was towed to the dealer. ICCU is now being ordered. The Master Warning light and 12V battery warning light illuminated. I was fortunate to be able to park in a parking lot just before all electrical died. An Internet search shows that this is a known issue; and, even after the replacement the situation can happen again. Took delivery 6/28/25. So, not even 6 months old.

On 2025-11-12, my car got BMS error P1B9700. On 2025-11-13, I took the car to local Kia dealer. The error is for battery temperature sensor. After 1 week, thst sensor have not been replaced nor any other numerous minor electrical defects were fixed. My car was just parked in dealer lot the whole time. No communication from Kia or dealer how to fix this potentionly dangerous battery problem.

I was driving over to walk my friends dog and I was pulling into the overflow parking area and my car just speed up and it would not stop. I went up a curb and I hit a small tree went down another curb crossed the street and then up another curb and the break would not stop the car. I finally just cut the car off

While charging at a L3 station, charging was interrupted with a pop (which turned out to be ablown fuse). Two warning lights appeared on the dashboard (battery and vehicle with exclamation points) as well as message to "Check electrical vehicle system". Kia Connect told me to exit the vehicle and that it would need to be towed to the dealer. Dealer Service Office confirmed it was not safe to be in the vehicle nor to drive it. Car had only 2311 miles at the time! From the dealer invoice the KDS was inoperative at the time. Fault codes: P1A961C LDS Internal Power Supply out of Range and P1A9096 LDC Input Voltage Sensor Component Internal Failure Confirmed 12V battery no charging in ready on. Live data does not match given good values. LDC input voltage ~2V, LDC Output voltage 11.4C Dealer re

While driving car began to decelerate and the dash lit up with a number of ABS/Brake system failure symbols. I was on the highway traveling at abt 70 mph when the issue happened. Got car to coast off hwy onto an upward sloping exit. Stopped at a light. Turned off and back on and was able to gain minor speed got approx three blocks to a gas station. Pulled off and tried restarts. The screen stated there was an update pending, but it could not complete it because the Electronic Brake System failed. I tried triggering a brake reset but it didn’t work. Car was towed back to Dealership. Two days later the Dealership mechanic confirmed the issue was a failed Electronic Brake which must be replaced. Car has now been with Dealer for 10 days. Dealer stated the EBS was on back order and they

As I was driving, there was a loud pop that came from the rear of the car. The vehicle immediately flashed a warning to “check electrical systems”. I pulled over as quickly as possible but was faced with reduced acceleration. I ended up stuck in a parking lot awaiting a tow truck for over an hour with my dog and my wife in the car headed to a surgery appointment. The dealership has not confirmed anything but from research it seems to be a known issue that Kia has not addressed.

Loud pop and Check Electrical System Message - limited ability to drive due to ICCU no longer charging 12V battery. Car no longer able to drive.

While driving Friday 4/17/26, I heard a pop and the car displayed a message to "Check electric vehicle system." The car seemed to still drive so I drive it home. That evening the car would not charge. I called Jim Shorkey Kia on 4/18/26, where I bought the car, to schedule the car to be looked at. They told me to bring it in on Monday and they will try to squeeze me in so they can diagnose the issue. Later that morning, I took that car out and made it about a block away before the car displayed a new message to "Stop vehicle and check power supply." At this point, the car went into a limp mode, barely moving. I was able to turn around and drive it home. Had I been on the highway, I might have been put in a dangerous situation. Now that the car has been diagnosed, the service department ca

I start vehicle and try to put transmission to drive its not working after I try to put vehicle to reverse transmission its not working

After 2474 miles, the vehicle Integrated Charging Control Unit (ICCU) failed in my 2025 Kia EV6 making the vehicle undrivable so it had to be towed to the Kia dealer. The ICCU was replaced under warranty. The failure of the ICCU in Kia, Hyundai and Genesis electric vehicles is fairly common and they have yet to come up with a permanent solution.

Issue Description: When parking facing downhill, I put the car in reverse but the car rolls forward. Feels like the car is either in drive or neutral. Concern is intermittent, and I confirmed each time it happens, gear selector is in reverse. When trying to re-engage reverse, the display shows "gear already selected." Safety risk: Car almost hit car in front of us while trying to reverse. Car was inspected by dealer service center. Could not duplicate, but found an error code. Dealership found multiple software updates available on the brand new car and installed.

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.

ICCU failure caused loss of power on interstate. I almost got in a wreck because of this. Kia dealer refused to look at my car. Took vehicle to independent repair shop who diagnosed issue.

The rear door of my KIA EV6 intermittently fails to open even when the vehicle is unlocked. The issue has been recorded on video and reported to an authorized KIA dealer, but it has not been repaired. A child safety seat is installed in the rear seat, and this defect creates a serious safety risk in an emergency where immediate access to the child is required. The vehicle is unsafe due to this defect.

While maneuvering my Kia EV6 into my garage, the vehicle accelerated unexpectedly and struck the garage wall. I believe the acceleration may have been unintentional or due to a malfunction. I request review of any vehicle event data

2025 KIA EV6 ICCU (part#36401 1XFD5) failed at 2,658 miles. Failure occurred when power was applied after reversing out of a parking space, switching to drive and applying power. No safety issues as vehicle remained controllable. Vehicle went into "limp" mode. Build date of vehicle is 6/20/2025. KIA Dealer has replaced failed ICCU with updated unit (part#36400 1XFD6). No indication of failure occured prior to the failure (an audible "POP" heard from the rear cabin when the unit failed).

KIA has created a safety hazard by removing the ability for the driver to select LIGHT or DARK mode for the two 7" data and infotainment screens in their 2025 and forward EV6 electric cars. Like many, I have to drive in very fast busy commuter traffic on highway I-66. (exaserbated by driving into the sun in the AM) The DARK mode screens have insufficient contrast even with the screen lighting turned all the way up. It takes the drivers eyes away from the road longer than is safe, particularly in high speed freeway commuter traffic. This is seriously exacerbated if the driver uses sunglasses because of the sun. This is obviously not an issue confined to highway I-66, or me.

Steering rack need to replace after drive almost 1900 miles. It has knocking nosie when turn the wheel, the car had been in the shop for three weeks.
