If you do a search, there's another thread on this topic from a month or so back.
Owners were experiencing similar issues. Some removed the phone case. Some removed the car charging pad's rubber liner. Some disable the phone's charging optimization like JMAB.
I'm not personally having any significant issues other than the phone sometimes getting somewhat hot. But it's a very odd thing . . . for some reason, wireless phone chargers in cars seem to be almost universally problematic. Volvo recently removed them from all their new cars. They overheat phones in all BMWs. Subaru owners are up in arms. I once saw a technical explanation for why what would appear to be a pretty simple and widely used technology is challenged in a car's environment, but I couldn't understand it. Lol.
