This is a well known issue that anyone researching a new Ioniq 5 or 6 or the EV6 should already be aware of. The ICCU failure has caused a number of cars to be laid up at dealerships for too many weeks as parts were difficult to come by despite it being a relatively common part failure.
This recall should see the end to this issue, although there have been software updates with the same claim.
