The EV3 ICCU issue, as I see it, is still an issue but does come with a solution.
Charging at a full 7.4kW can cause the ICCU to ‘trip’ where it drops the charge rate to trickle. Apparently, stopping the charge and trying later can resolve this once it’s tripped but I’ve seen no clarity on how much later really is. What is clear is that charging at 90% of full rate avoids the whole problem.
There is no sign of the EV5 having any issues with the ICCU, although it’s not been out for long.

I'll try to give my honest opinion but am always open to learning.
