Leaving our home garage a loud popping sound was heard and dashboard warning signals came on indicating battery failure. Dealer confirmed the ICCU failed.

With 3100 mileage, the car experienced an electric systems failure which resulted in the car no longer being functional. Towed to dealership where they officially stated a failure of the ICCU. Will have to wait days, possibly weeks for replacement part, but no guarantee this won't happen again.

I was driving on the CA 405 SB, Long Beach, at about 6 PM 9/19/25. All of a sudden this loud screeching noise started.

The Lane Keeping Assist works well and is very useful. Unfortunately it is combined with the infrared eye monitor system, which is very flaky and does not work well with prescription glasses when sunlight comes in from the front or side.
