I have not gotten the dimmed screen and message. But the few times I've had mine on the wireless charger I did notice it was pretty warm coming off of it. By chance was she using GPS, Google Maps, Waze, or Apple Maps, through apple car play while on her drive? Or possibly streaming music?
I’ve experienced the same issue with my GCL—and with my previous vehicle (Audi). In both vehicles, when using CarPlay wirelessly, the phone gets quite hot (to the point of overheating) while trying to “charge“ wirelessly. The worst part is that the wireless chargers can’t even keep up with the phone‘s consumption. At best, my battery level would remain constant, but typically, it would actually lose power while still charging continuously and overheating. I think the flaw is with Apple on this one. In both cases, I just use a USB-C cord from the second row and snake it up between the center consul and passenger seat for easy charging. That way, I don’t have to have the cable coming out of the center stack (personal preference). I still use wireless CarPlay (when I can get it to connect in the Jeep), which allows me to unplug the phone from the charging cable if I need to without the music and the other functions stopping. In this configuration, the phone does not overheat, no matter how long I leave it plugged-in to the charging cable.
