The noise reducing laminated
The noise reducing laminated glass, AKA rock catching glass is a night mare. This stuff is s@$t.
I had a small stone fly up and get trapped in the hollow layer.
I immediately went to an epoxy repair place and even though the “ chip “ was filled it started cracking and the only recourse was to change the window.
Subaru charges an iSight recalibration fee which is why it costs so much.
I have heard that the replacement windows slight refractive difference will trigger and shut down iSight. All Subaru does is activate a software “ button “ and then go for a drive around the block.
When enabled “by Subaru” the system is actually self calibrating.
Corning is making windows for f150s out of gorilla glass. Hopefully the next replacement I buy won’t be from Subaru.
