Vehicle has continuous ongoing issues since day of purchase with big screen radio display. System randomly changes screens and drops connection with source over and over again while vehicle is in operation. This is also affecting the rear parking assist sensor system making it work randomly at times and give false triggers or sometimes no triggers when collision is about to happen. The random screen changes are an EXTREME distraction while driving because the screen is extremely large in the center stack and when the image is randomly changing in your peripheral vision it draws driver’s attention off the road. These connection issues also affect audio sources and make it necessary for the driver to interact with touch screen a ridiculous number of times per short drive further distracting the driver. There has been ongoing issues with this vehicle since the day I purchased it new. Multiple attempts by multiple different Ram dealerships to repair/resolve the issues with no solutions found yet. Actual radio unit in dash was replaced with 2 new units by dealers in attempts to resolve issues with no improvements. Dealerships have worked with Ram engineering and opened multiple STAR cases on vehicle in relation to these problems. Contacted Ram customer care multiple times and requested Ram buyback or deem this vehicle as lemon law vehicle. To date vehicle has been in for attempted service for these issues more than 4 times and would have been in 2-3 times this number of visits if not such an extreme inconvenience. Demanded Ram buyback the vehicle and have got pushback from them. Vehicle has been in service since May 2023, was purchased new from dealer with less than 100 miles on odometer.
