“I'm not sure what's going on. It's telling me to start stop the car when it's running and then it will turn off and go into accessory mode even when I'm driving that's dangerous. I took it to Kia a month ago for the same thing but they said they couldn't find anything, but it has to be something if I'm not the only one saying this is happening to their car. my car doesn't even have 8000 miles on my car.”

NHTSA complaint #11750872, filed 2026-07

“The digital instrument panel (including infotainment screen) has occasionally turned off and back on. An article showed Kia and Hyundai were going to have a recall at the end of March for this problem, but noted only 2025 K4 vehicles built after Aug 4, 2025 were involved, while the door frame shows my vehicle built 7/2025. Please include my vehicle VIN in the planned software update for the problem to correct the instrument panel screen occasionally turning off and back on. (vehicle recently bought Jan. 2026)”

“I am reporting ongoing safety issues with my Kia K4 LXS involving driver assistance systems and steering control. While driving in heavy rain with reduced visibility, the vehicle disabled multiple sensors and displayed a “camera obscured” message along with inattentive driving warnings, despite both of my hands being on the steering wheel and my full attention on the road. The loss of driver assistance features during hazardous weather conditions created a distracting and dangerous situation. This issue occurs frequently. …”

“I purchased my 2025 Kia K4 in March 2025. Approximately two months after purchasing the vehicle, around May 2025, I began experiencing serious and recurring safety issues. While driving, the vehicle intermittently loses acceleration and becomes unresponsive when I press the gas pedal. When this occurs, I have to pull over, turn the vehicle off, and restart it before I can continue driving. On other occasions, the vehicle has unexpectedly shut off and restarted on its own while I was driving. The dashboard also goes completely black during these incidents. …”

“I own a 2025 Kia K4 that has experienced multiple serious defects since purchase, raising ongoing safety concerns. Within the first four months, my windshield has failed or cracked four times, with one replacement denied by Kia and paid out-of-pocket. The windshield continues to make loud cracking noises, suggesting a structural defect that has not been resolved. In addition, the sunroof does not open or close properly, and while Kia acknowledged the defect, they only offered a potential software adjustment that does not address the root cause. …”
