if you read the article it explains how just being around an attcker with bluetooth on can give them access to bluetooth devices, and i assume the bluetooth on the car is always on. your phone can be infected and then infect your car and or things on your wifi. bluetooth is extremely unsafe. thats why i was suggesting scanning your phone. id reset the car and see if it is still there after it could be the same thing as a dns hijacker where it doesnt do too much.
the fbi warning could be coming from your phone, when i connect to my car, it says iphone connecting, so maybe something renamed your phone
The answer has been found. My friend's iPhone is called FBI is watching. He and his wife used my car a while back, and Bluetooth was trying to connect to his phone. Since he wasn't in the car, it wasn't able to connect.
