Folks, I've been in a similar predicament since mid-December 2024 and still don't have my vehicle back in my hands. Unfortunately, last year some road debris (a large sheet of metal) was kicked up by another vehicle ahead of me, causing catastrophic damage to my windshield and creasing the passenger-side A-pillar.
I called the dealer, but they wouldn't take the car for repairs since the work required replacing the windshield, which they just outsource anyway. So, I worked with my insurance to get it into an auto repair facility. It's still there, waiting for a back-ordered windshield with no ETA.
After some research, I found the Lexus Brand Engagement number: 800-255-3987. I highly recommend that anyone experiencing similar issues flood them with calls and open cases regarding these delays.
I have an active case with them now, and based on what they've told me, it seems that 400 windshield units are being shipped to the U.S. Rumor has it that this part is shared with the Land Cruiser, so owners of those vehicles are likely in the same boat as we are.
