I have let my friends in service and parts know about the issue and that I will at some point need to look into this for (potentially) warranty. It's a little bit of spreading the word, a start a least.
So this is the final list of what you replaced (compiled from a couple of posts)?
Strut mount bolts (M8x1.25 grade 10.9 flange bolt with OEM hardened steel spacers)
(2) AD-1094 strut bearings @8.56ea
(2) AD-1098 strut mounts @10.80ea
(2) HN1 center strut nuts @7.08ea
(1) DV6Z-16A200-A strut tower brace @77.31
