2020 Longhorn, no sunroof, build date 7/19, about 550 miles on the odometer.
I feel like I looked for this last week and didn't notice anything, but I can't be sure.
I don't know if it shows in these phone photos, but there does appear to be some discoloration or straining on the plastic there. I've got a black headliner, but I'll obviously have to keep an eye on this and prepare for what seems inevitable.
I'll see if I can track the progress over time to see if a crack develops slowly, or if it suddenly appears some day or what. Interesting situation for sure.
