Hi @Rclksr! Welcome to community.
I checked the Pandora account associated with your community profile and see that you are free ad-supported subscriber. The option to download content for offline listening is only available to Plus or Premium subscribers.
Can you share a screenshot of what the download looks like?
If you mean that playback begins when you connect to your vehicle I would check to see if the Enable Launch From Car under Settings has been disabled.
You can find feature by tapping on Profile
Tap Settings (the gear icon in the top right)
Tap Advanced
Scroll down to Bluetooth Devices
Toggle off Enable Launch From Car
