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 bou

20260116VEHICLE SPEED CONTROL

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
