It can be confusing since different states have different rules for glass coverage/replacement. When you watch commercials they give you the blanket "your windshield may be replaced at no charge to you" wording, which just depends on a few factors. Last year when both mine and my wife's windshields had to be replaced, since it was the first time I had ever dealt with it, I just assumed, because the general narrative out there is that glass is just automatically replaced with no deductible, that I was just gonna get it taken care of by insurance. And because my vehicles were so expensive, there would be no question about OEM glass being used, especially with all the dependent features. I was wrong on both counts.
Safelite "partners" with most if not all insurance companies, and they were the default vendor with mine. When I submitted my claim online, it gave me no other vendor alternative. So they scheduled Safelite to come to the house and replace windshields. The tech kinda scoffed and giggled under his breath like I was an idiot and said "with these vehicles I have no idea why you wouldn't go with OEM glass instead of this cheap stuff that will cause your HUD and other stuff not to work...." A can of worms opened...
I called Safelite and they of course said they just do what the insurance companies tell them, and that they can't on their own determine that my vehicle qualifies for OEM glass.
So I called my insurance company. They said that in the fine print of my policy that they can, at their discretion, not use OEM glass and that I would have to pay full price for it if I wanted it. What they didn't tell me of course is that I can use any glass company I want.
I called a local company and they laughed at the whole thing and said "you'll get OEM glass with us, we deal with insurance companies daily..." They also said they won't install anything other than OEM glass when tech features depend on them, never have and never will.
A couple days later I had OEM glass and paid nothing but my deductible. It pays to shop around, but your insurance company prolly won't tell you that, since they get spiffs when you use Safelite, or whoever else they contract with.
The insurance companies are just trying to make as much money as they can.
