“I purchased my 2025 Kia K4 in March 2025. Approximately two months after purchasing the vehicle, around May 2025, I began experiencing serious and recurring safety issues. While driving, the vehicle intermittently loses acceleration and becomes unresponsive when I press the gas pedal. When this occurs, I have to pull over, turn the vehicle off, and restart it before I can continue driving. On other occasions, the vehicle has unexpectedly shut off and restarted on its own while I was driving. The dashboard also goes completely black during these incidents. …”
