Same here. Rock hit, then 12" crack(and growing).My iInsurance partners with Safelite, so went there even though I could pick anyone, but thought if anyone had EV6 experience, they would. I was told there are no OEM replacements yet, so ordered through the dealer and installed 2 days ago.
When I got home, I discovered a very visible line across the roof connecting to the top corners of the glass, probably where tape went? Called the Safelite where installed and wanted to speak to a tech. They wouldn't come to the phone but the desk person said they advised using Goof Off, which I'd already tried. This wasn't residue, it was much more lasting and seemed imbedded. After working with Scratch Remover and Turtle Wax Polishing Compound, I finally got it to the point that I only see a faint darker color discoloration line(car is Interstellar Gray). No one else would notice unless I pointed it out. As if whatever was used, interacted with the clear coat?
Now to the camera calibration: They assured me they had the EV6 support for calibration. So they did it. Prior to this incident, my car would trigger the departure warning when a tire hit outside of the white line. Now, only after the car has went well over the line. So now a trip to the dealer for a camera calibration.
It was obvious the local place had no interest in dealing with any of this as I assume they saw it too and hoped it would slip by me. And I didn't push it as I didn't want those bozos anywhere near my car again. I'm communicating with the Safelite district office now but will never use Safelite again.
As far as the new glass, it looks properly installed so fingers crossed on that. BTW, the tech told me after installation, it's the same procedure as on the Stinger.
