Going thru this same issue…
Going thru this same issue on daughter's car 2020 Forester, bought new. 71,000 miles and a copy of the 2021 Subaru service bulletin, but not under warranty? 60,000 mile warranty for something they were aware of and redesigned the part due to failures. I question if it should not also be covered by the Federal Warranty for emissions as the EGR is compromised by this failure as well.Goes into shop tomorrow, so will know more after.
