prior case 11708370 filed 1/2/2026 spoke with [redacted] 1/22/2026. Friday 2/6/2026 Shorkey Kia Wexford calls and tells me my EV6 is fixed I can pick it up. I go into the Kia App and still have the same 3 codes as before; P056216 VCU, C160404 FR_Radar, and C28B186 ADAS_DRV. I tell them later that day when I had time to open the app to make sure the codes were corrected, called them back and said until these codes are cleared, my vehicle is not fixed. Tuesday 2/10/2026 I get a called from same person at Shorkey Kia in Wexford, telling me my vehicle is fixed, I can pick up my vehicle, same person her name is Maggie. I told Maggie to hold while I bring up the Kia app, I still see the same 3 codes: P056216, C160404, C28B186. I told her the codes are still active, and as long as these codes are present, the car isn't fixed. …
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 called and told me that the failed component was the ICCU. …
Transmission & drivetrain
Hi, I had to transport a few lumber pieces that did not fit into the trunk of my Kia EV6, so I had to leave the hatch open (I pulled it down as far as possible and secured it via a rope against the latch). When I started driving the car started beeping frantically, but allowed me to drive. When I crossed an intersection traffic came to a temporary halt, and when I came to a stop my Kia all of a sudden shut off and would not allow me to put it back into gear again. When traffic around me continued I was unable to move and presented a security hazard with cars coming from behind almost running into me because they expected me to move, which I couldn't. I inquired about this at my dealership this morning and was told that there is no way to override the car's behavior and that this behavior was a "safety feature" to ensure the car wouldn't be driven with the hatch open. …
I have experienced a ICCU failure at 7200 miles on my 2025 EV6 GT Line. This failure is a safety hazard as it will quickly disable the vehicle and strand the occupants wherever they be at the time of failure. (highway, back roads, day or night). There are warning lights when this occurs, but there is a very limited time to get to safety, depending on the state of charge of the onboard 12v battery. This issue has been ongoing since this vehicle came out in 2022. There have been a number of recalls to address the problem, but apparently without success. I see postings all the time with others experiencing this failure. When I inquired about the availability of the replacement ICCU, I was told that the part was on national back order. I was also told there were 147 units in transit, 47 were already spoken for. This seems to indicate that this is a very common issue, affecting many drivers.
Fuel & propulsion system
initially filed [redacted] (1/2/2026) 2nd (additional info) filed [redacted] (2/10/2026 3rd (3 page service report) [redacted] (2/11/2026) Vehicle is registered to Christopher Rojik, however it is my car that I drive, etc. today I am filing this for you folks that since I filed the complaint with Kia Corp. and sent them the service report, etc. Today, 2/19/2026 I received a formal Settlement Agreement and General Release to sign and accept. I am not signing it, as well as it fully releases Kia from any future issues, etc. outside of the warranty and whatever other details it claims. This will or should be the last for me to file. I had no idea they send me this kind of offer. As it is listed specifically as a "GOODWILL GESTURE" and they are not accepting fault or something like that. I attached inidividual pages, hopefully I can upload them as pdfs, we will see. …
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, especially with the sudden failure and loss of power. …
