It also engaged emergency braking going forward when there was no reason to do so. Many times when I am backing up, it's engaged emergency …

ICCU failure, a well known issue with these cars.

Iccu failure with Kia ev6. Unreal that this car has not had a recall yet. It is totally unacceptable that this car can at any time fail. Car will not start and shut down while I was driving. Luckily I was beginning to park when it happened

The ICCU unit failed. The message "Check Electrical System" appeared on the instrument cluster. Low-voltage battery voltage was 12.0V and vehicle speed was limited to 60 mph.
