The 2025KIAK4 carries 54 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 14 crashes, 0 fires, 6 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 4/5 front crash, 5/5 side crash, and 5/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2025 K4 is electrical system with 8 filings, followed by unknown or other (8) and lane departure: warning (4). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 2 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 38 investigation files overlapping the 2025 K4, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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 Iâm hitting the brakes. Once stopped, it then doesnât want to accelerate. Iâve reported to the dealership and they try to tell me itâs the type of transmission it has and that itâs 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 donât feel safe driving it. The lane assist and emergency braking system is also extremely inaccurate and over corrects when it shouldnât especially in bad weather. Emergency braking is detecting stuff in front of me that isnât actually there, same with in reverse it sees things extremely far away and prevents you from moving, although itâs 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 ânothing wrongâ with the vehicle and that I simply did not know how to drive it. Despite this, the obstruction remains and continues to interfere with saf
Location: Intersection of [XXX] and [XXX] Lakeville, MN Date/Time: [XXX], at approximately [XXX] Vehicle: 2025 Kia K4 (911 call placed at 10:08 am) On [XXX], while traveling toward the roundabout at [XXX] and [XXX], my vehicle experienced a sudden and violent unintended acceleration. Despite having my foot completely off the gas pedal, the engine began to accelerate the vehicle rapidly on its own. I immediately attempted to regain control by pumping the brake pedal repeatedly with significant force. These efforts had no effect; the vehicle continued to accelerate faster and faster. As the speed increased, the vehicle began to swerve, and I realized I was losing control while rapidly closing the distance between myself, the roundabout, and the vehicles ahead of me. Fortunately, the right lane was clear. Because the vehicle was already veering in that direction and the brakes were failing to slow the car, I made a split-second decision to steer into a large snowbank to avoid a high-s
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 âcamera obscuredâ 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 regularly receive false inattentive driving and hands-on-wheel warnings even when I am driving properly. These alerts are distracting and interfere with safe vehicle operation. I am also experiencing lane control and steering interference. The steering wheel will sometimes pull the vehicle in a direction that does not match the road, even when lane assist is turned off. This is especially dangerous in construction zones with temporary lanes marked by reflecto
