NHTSA Complaint #11685374 — 2022 HYUNDAI KONA N

There would be a stumble when accelerating up to highway speeds at random times. During acceleration on a highway on August 30, 2025, that stumble became constant and the engine light came on. Exhaust sounds was no longer smooth and constant but rather a constant sputter. Greater vibration was felt in the car anytime the accelerator was depressed. Pulled off the highway and can visually see the motor vibrating significantly. When accelerating from a stop or crawling speed, it struggles to move and I can feel the resistance of the car not wanting to accelerate. Auto parts store scanned the code and it came back as a misfire in cylinder 3. Concerned about engine damage, being stranded, or causing an accident, the car was dropped it off at the Hyundai dealership. At that time (around 2pm) I was far from home and the service center was closed. On 9/5/2025 I was notified that the fuel injectors will need to be replaced and they are currently on order.
