My 2020 3500 Limited leather dash started lifting too. Truck is garaged with ceramic tint, and windshield sun shade is installed when parked but not in the garage. Out of warranty and didn't trust the dealer replacing it so I did it myself. Wasn't hard, took me about 9 hours taking my time with 30 min lunch break and watching football on and off. The bubbling wasn't bad, but enough to bug me. I tried to fix it using the small injection needle method but I couldn't get the glue to spread evenly. I think because there is a thin layer of padding under the leather that prevents the glue from evenly spreading.
