2025 Kia K4 Complaints

The 2025 Kia K4 sensors failed to go off resulting in the rear bumper to hit a barrell. The operator of the Kia K4 was reversing at 1mph

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)

When I drive over 65 mph, I feel the car lose stability, and sometimes I feel those movements in the steering wheel. Also, it doesn't show the actual tire tread depth. In addition. And there is a burning smell.

There are times my vehicle keeps accelerating even though I’m hitting the brakes. Once stopped, it then doesn’t want to accelerate. I’ve reported to the dealership and they try to tell me it’s the type of transmission it has and that it’s normal. Continuing to accelerate while braking is extremely unsafe. My engine is also making a ticking noise that it never used to make. I bought my car brand new in October of 2025. I left the dealership with 9 miles on it, I now have 25k miles on it and I don’t feel safe driving it. The lane assist and emergency braking system is also extremely inaccurate and over corrects when it shouldn’t especially in bad weather. Emergency braking is detecting stuff in front of me that isn’t actually there, same with in reverse it sees things extremely far away and prevents you from moving, although it’s safe to do so.

I am reporting a serious safety defect involving the brake pedal area of my newly leased Kia K4 GT-Line. There is a metal bracket/component located directly above the brake pedal that interferes with foot placement. My foot becomes caught on this bracket when attempting to apply the brake, which delays or prevents proper brake application. On [XXX], while exiting the roadway and attempting to stop at a stop sign, my foot became stuck on this bracket as I applied the brake. This caused a delay in braking and nearly resulted in an accident. I was shocked and frightened, as this situation could have resulted in a life-threatening collision. I took the vehicle to the dealership, Kia Beavercreek in Dayton, Ohio, for inspection. The dealership reviewed the vehicle and stated that they were unable to fix the issue. I was told there was “nothing wrong” with the vehicle and that I simply did not know how to drive it. Despite this, the obstruction remains and continues to interfere with safe br...
