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.

Bought my Kia k4 2025 in February at DTLA Kia and the experience has been [XXX]. The first day driving I went up near dodgers stadium , immediately had a burnt smell. 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. Turned it back on while getting honked at and that was that. $700 a month for a lack of urgency to help me. Boo Kia. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION
