  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-speed rear-end collision. The force of the impact with the snowbank was substantial, resulting in the front body panel and a lower front component being torn off the vehicle. The Lakeville Police and Fire Departments responded to the scene and were required to dig the vehicle out of the snow pile. I have attached the official police report to this statement. Had I not maintained a safe following distance or made the decision to steer off the road, the result would have been a catastrophic multi-vehicle collision.

  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 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 reflectors, including when driving next to large trucks. I have experienced multiple near-miss incidents and have had to physically override the steering wheel to remain in my lane. These problems now occur almost every time I drive and have caused me to feel unsafe operating the vehicle. I believe this represents a serious safety defect.

  Bought car in Nov 24. Noticed a popping sound as if a rock was hitting windshield. Nothing hit windshield. The popping sound was intermittent but went on for months. Finally in August 2025, I noticed a crack in upper side of drivers windshield. Next day crack got bigger. Called safelite to replace. Had to park car with cover over windshield since I couldn’t get an appointment right away. Had to rent a car. Windshield replaced. Popping continues, less frequently but it still pops. Took it to Burlington Kia and explained my issue. They could not replicate the popping sound.

The owner was provided with vehicle rental assistance. The contact stated that the dealer contacted the owner after 6 weeks and advised that the cause of the failure could not be determined; however, the owner was able to verify through the Mobile App that the dealer had only driven the vehicle twice, and the vehicle failed to exceed 38 MPH while driving. The vehicle was not repaired. The manufacturer was contacted for buy-back assistance, but the request was denied. The contact stated that a local Kia sales advisor stated that a consumer who owned the same vehicle had experienced a similar failure. The failure mileage was approximately 50.

• 09/25/2025· UNKNOWN OR OTHER

  I had a diagnostic appointment on 9/8/25 for my 2025 Kia K4 due to a popping noise on the windshield that happens when the weather is hot/sun on windshield. Once the diagnostic was complete, the recommendation from the dealer was to replace the windshield since it was not factory. The dealer did hear the noise during the diagnostic. I purchased the vehicle Jan 2025 and I start hearing the popping noise in June 2025 (factory windshield #1). In August 2025, the windshield was replaced by a company due to what I assumed was a rock hitting my windshield that cause a crack that grew rapidly (windshield #2). The noise continued. My diagnostic results recommended replacing the windshield again. The windshield was replaced again in Sep 2025 (windshield #3). The windshield is still making the same popping noise when out in the sun. From what I've read, this is an ongoing issue with the 2025 Kia K4 vehicles regarding a possible plastic dashboard trim contracting and expanding in the new K4 vehicles.

  There is a defect with the WINDSHIELD glass. The windshield glass gives off an audible "SNAP" or "POP" noise when the inside of the windshield glass experiences a stress crack. This is not a crack that can be felt from the inside, or the outside. It is actually inside the glass and it can only be seen when the sun hits the windshield a certain way. Eventually failure of the windshield is imminent. The windshield glass internally fractures under normal driving conditions. It happens commonly, and intermittently, probably at least once per week.

• 08/20/2025· ELECTRICAL SYSTEM,SEATS,UNKNOWN OR OTHER

  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. The vehicle also makes loud, unpredictable popping noises from the dashboard, a problem that multiple other Kia owners at the same dealership have reported. The dealer confirmed that Kia does not have a fix and only offered to temporarily “push in the dashboard.” Furthermore, the seat cooling system has stopped working entirely without repair options provided. These defects compromise the safety and reliability of the vehicle, creating risks of reduced visibility, potential structural failure, and driver distraction. All issues have been reported and documented at Courtesy Kia of Brandon, FL, and confirmed by the dealer, but Kia has failed to provide adequate remedies. No warning lights or error messages appeared prior to these failures. I have also filed reports with the Better Business Bureau Auto Line, the Florida Attorney General’s Office, and Kia Customer Care, but no meaningful resolution has been provided. These ongoing unresolved defects indicate systemic safety issues with the Kia K4.

  I am submitting this complaint regarding a suspected safety defect involving a 2025 Kia K4. On XXX, the vehicle was involved in a single-vehicle crash in the Town of [XXX]. According to the driver, the vehicle unexpectedly steered off the roadway when the Lane Keeping Assist/Lane Centering steering system appeared to intervene. The driver attempted to maintain control but was unable to keep the vehicle on the roadway. The vehicle entered a ditch and struck a utility pole, causing significant damage to the passenger side. The front and rear passenger-side airbags deployed. The front passenger window shattered, sending broken glass onto the front and rear passengers. My daughter was seated in the front passenger seat, and my [XXX] granddaughter was properly restrained in a rear child safety seat. Both sustained injuries and required medical evaluation following the crash. After the collision, I began researching similar incidents and found other owners reporting concerns involving the steering assistance and lane-keeping systems. While I cannot determine the exact cause of this crash, I believe the possibility of an unintended Lane Keeping Assist or steering system intervention should be investigated because it may present a safety risk to other motorists. I respectfully request that the National Highway Traffic Safety Administration review this incident, along with any similar complaints involving the 2025 Kia K4, to determine whether a defect exists in the vehicle's steering assistance, Lane Keeping Assist, Lane Following Assist, or other Advanced Driver Assistance Systems (ADAS). Supporting documentation can be provided if requested. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This issue has occurred 5 times so far and 4 of them being while driving the car within 1 week. The dealer is confirmed this is an issue and recommended an entire dashboard replacement for the vehicle. This is very unsafe because i cannot determine my speed or any other important warnings the vehicle may give me during my drive. There were no warnings or symptoms prior to the first failure.

  The car completely cut off while driving on the highway going 65 mph. This isn’t the first time it has turned off while driving. I had to pull over and put the car in park before it would turn back on. The error says Accessory Mode. I have taken the vehicle to Kia Dealership in Winston Salem but they told me they are unable to recreate the issue so they are unable to assist with the problem. The car turning off while driving has happened at least 20 times. I have repeatedly called Kia and they are unwilling to diagnose an issue with the vehicle unless it happens while they have it. I am putting myself and others at danger driving this vehicle. I contacted Hertz Auto sales where I purchased it and they directed me to contact Kia since I have a warranty. I plan on taking the car again but I can only hope the issue happens while they have it because this vehicle is VERY dangerous to be on the road and I have no other option than to be at the dealerships mercy.

I disregarded it thinking maybe its fresh paint burning , WRONG. Till this day 4 months later my tail pipe throws a musty smell. Issue number 2 , the hesitant gas pedal. Who knows what it is maybe fuel system , transmission but daily and I mean DAILY my accelaration is poor,jerky, struggling and overall doesn't work. It has its good mornings but once I'm on the road for more than 10 minutes its back to the struggle. I've had my K4 serviced twice at Dtla service, they never once test drove the car because I was tracking the GPS almost all day for the three days they had it. Once I got my car back it tooks about 45 minutes the service advisor Jeffery Montoya was so lost on where my car was, I had to ask and ask and ask finally the guys who are out front welcoming you helped me and brought my car. That was my decision to never go back to DTLA service. Next took it to Van Nuys Kia waited to weeks from my appointment because they are moving. Finally they kept it for three days they still werent able to diagnose the issue and repair it. Modesto the advisor there said " we can't duplicate the issue''. Some how they made me pay $82 because they supposedly found plastic bags stuck to my exhuast. [XXX] I even told him I don't want it cleaned and he said oh well you authorized the diag so you have to. He reported that info to kia Corp which got my case closed and said the car works fine. NO it does not work fine. Never going. Now today [XXX] I was parking arriving somewhere the k4 said engine off shift to P while ringing the alarm from the dash. I have it on film. Second driving down [XXX] and boom car engine shuts off while car are behind me. I had to shift to p then turn the car off.

  To whom this may concern, I was using my cruise control on my way to work. I usually set it to 80 because police are okay with that speed on I-75. I braked before my automatic brakes hit after I got cut off. I pressed resume in the cruise control and it accelerated pretty quick. I’ve experienced that quite a bit, but there’s been a few times that the car exceeded the set cruising speed while trying to resume. I forget it happens because it’s happened about 4 times since purchasing the vehicle. I noticed an officer on the shoulder leaving the shoulder as I got closer, and he got right behind me and cut his lights on, I look down and the cruise control shows 80 above the speedometer (photo attached taken while pulled over), BUT the arm was past the tick for 90. The officer clocked me at 92 apparently. This is the only time this issue has occurred, and I informed the officer that this happens. I have a court date set for July 9th now. I Googled to see if other owners have this problem. There are others who expressed experiencing this in their K4s and K5s. The AI tool explained the following • "Resume" Behavior: When you press the resume button, the car attempts to get back to 80 mph as quickly as possible. This aggressive acceleration can cause it to temporarily overshoot the target speed before settling down. • Settings Sensitivity: The acceleration strength and reaction speed can be set to "Fast" in your infotainment system, causing more aggressive throttle input.

• 04/06/2026· STEERINGCrash

  While driving my 2025 Kia K4, the steering system failed and became unresponsive. I was unable to steer the vehicle as intended. The exact cause of the steering failure is UNKNOWN at this time. The vehicle and steering components are available for inspection upon request. The loss of steering control put my safety and passengers riding at serious risk because I could not properly control the direction of the vehicle. Steering is essential for avoiding hazards, staying in the lane, and maintaining control. The failure resulted in a single‑vehicle accident and could have caused serious injury or involved other motorists if traffic conditions had been different. The problem has not yet been confirmed by a Kia dealership or an independent service center. At the time of this report, the vehicle has not been inspected by Kia or another repair facility. Police and/or insurance involvement may have occurred due to the accident, but no mechanical inspection of the steering system has been completed yet. There were no warning lights, messages, or alerts prior to the steering failure. The problem occurred suddenly and without warning while the vehicle was being driven. I did not notice any clear symptoms before losing steering control. The exact cause of the steering failure is UNKNOWN. Based on my personal experience, the failure was sudden and unexpected and occurred during normal driving conditions. I had no prior indication that there was a problem with the steering system before the accident occurred.

  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.

• 01/15/2026· SERVICE BRAKES

  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 braking. Because this defect directly affects my ability to safely apply the brakes, I do not feel safe operating this vehicle. This is a critical safety issue involving brake operation that poses a risk of serious injury or death. The vehicle has extremely low mileage, and the dealership has acknowledged the concern but stated it cannot be corrected. Photos of the brake pedal area are available and clearly show the metal bracket near the brake pedal that causes the obstruction I can not put life and others life in danger driving this car.
