Never had it in the Soul (1200milies @4m/kWh

).
But the GTE would rarely have a similar fault, while driving with ACC on. It would easily clear after restart or even by itself after some time. After a while I presumed that it was any sort of obstruction, such as dirt/heavy rain, blocking the front facing radar at the front of the car.
Never caused any substantial damage, but if you are driving the SOUL at the moment this happens, you have to make sure that you are in full control of the car as some of the auto functions might be impaired!
There is either Kona or Niro thread on a similar topic, try and find it.
