Per the geekwire article linked above, one of the local Mazda dealerships blamed 5G for causing the issue. Apparently that's the popular thing to do these days.

Tangentially related, an old ham radio operator related his advice for putting up an antenna on your house: "Put the antenna up, but don't connect it to anything for a few weeks. Don't even run the cable yet. When people complain about it making their fillings vibrate or garage door open or whatever, you can show them that it isn't even connected to anything. This helps filter out the people who have nothing better to do than to complain."
