My car isn't plugged in, so definitely not the charger. Have you noticed the noise before tonight?Also hearing this same noise but I assumed it was my battery charging. Car is currently charging in the driveway, and I was sitting in the car for about 5 minutes trying to connect to my weak-signaled wifi network. Heard this on and off "fan noise" that would come and go every 30 sec or so
I'm also having Wi-Fi issues. I have two routers and it only stays connected to then for a couple seconds before reverting to LTE. I created a Wi-Fi hotspot with a phone and it stays connected without any problems.
