I have a 2018 DD, and my radio screen is doing the same thing. The screen looks like it has a huge bubble, the "adjust clock " notification constantly pops up, the screen freezes up; where I can't use any of the functions (no radio, no back up camera, no control over the thermostat, no navigation, cant answer the phone etc). I have to disconnect my battery just to get the screen to go off because it wont shut off after the vehicle is turned off. I took it to the dealership and they said I needed a new radio and it's going to cost $3000. This issue sounds like a manufacturer defect. I've done research and seen class action lawsuits pertaining to this, other forums of people with the same issue. To see so many people having the same issue is indicative of a manufacturer defect and should be grounds for a recall. I've talked to FCA and Dodge care, they are aware of the issue but aren't going to do anything about it. Basically they know it's a potential safety issue but it's not their issue as the company, it's your issue as the consumer, it what they told me. Oh but get it fixed and save your receipt if a recall is issued you'd be compensated, is what they told me as well. That's BS to my ears.
Please report your issue to the National Highway Traffic Safety Administration's.

Maybe if they enough people report it and shine some light on the issue, some real help and compensation will happen
