Same issue, so I googled wireless charging not working on an xt5. It took me to the my cadillac page and there I found a phone compatibility link. Unless you have a 2019 or newer, it shows which phones are compatible and of course my mote 9 is not. It does say you can take it to the dealership and have them update the charger but im sure thats pretty pricey. Ill look into it and advise. Hope this helps!
