Outside temp was 33 degrees F with a slightly lower windchill. I started the car and, when I accelerated to 30 mph, my car began to beep and the dashboard indicated the speed was limited to 30 mph. It went into limp mode and resisted when I tried to go above 30. We were towed to Kia but they could not replicate the issue and said it may have been due to the cold. A Google search showed others with 2025 model Kias also had the issue and they also happened during colder temps. I was glad I was on a 40 mph road and not a highway or it could have been a dangerous issue. There was no indication of any issue until I tried to accelerate to 30 mph. It drove fine the night before when it was also below freezing.
