I've got a 2019 RAM 1500 with a series of uconnect issues that I seem to be getting nowhere with. It's the 8.4 with nav variety, which isn't working correctly as in XM guardian not functioning reliably via the SOS or assist, some system controls/apps sometimes don't appear, radio skips whether it's XM or Bluetooth, and there are issues with items otherwise set via the controls via the uconnect like the parking brake do not always work. The auto parking brake, for example, works about half the time - which is obviously a safety issue. When the dealer looked at it, they came to the conclusion it should be replaced. However, in spite of my attempts to work with the dealer and RAM. I've not gotten a replacement/resolution. Is there some reason neither the dealer or RAM seems to be unable to fix this?
