I’ve seen that issue with the material being pulled from the bottom edge of the pull handles on several gmt800’s ironically none of mine have experienced that. Not sure what causes it. But those pull handles are removable from the rest of the panel. I swapped mine around when I was messing around with interior pieces years back and made my own 2 tone interior. I think it’s just a few 7mm screws. Maybe if you pull that off then Rewrap the material and glue it back on. Yes. These.
I got the grills back installed BTW. I think they look good.
