The update in this case was software. It reduces the charging rate and runs fans during charging to lower the temperature the ICCU has to endure. I bought my car in early 2025 with the update in place and never ran the ICCU at the older, higher temperature. I suspect that a fix like that wouldn’t help anyone who had already baked theirs for months or years.
It got an update in fall of 2024 that is supposed to fix it. Hasn’t been a problem so far.
Real Subaru ‘we fixed the head gaskets, for real this time’ vibes
Subaru never offered 15 year warranty on their head gaskets.

I did too. Then my iccu failed 4 months later.
With 15 year warranty, you forgot that part.
Sure. It was at the dealer for 2+ months.
I have no doubt that they’ll replace it every time it pops for the next 15 years.
But I’ve also heard they take a long time to complete the repairs
Did you have the car before the update? Or did you buy it new with the update in place?
