Sounds like a problem with the phone, and not the car? What type of phone?

We have a 2017 Tundra and 2018 Highlander. When the ignition is in the off position, my phone is disconnected as there is nothing to connect to. The cars don't show up as available devices, when I look for Bluetooth connections, until the dash display is on.
