Software problems of the 2016 Cadillac Escalade

Around 20,000 miles we started documenting issues with the drive train by taking it into the dealership but we had had these issues prior to the 20,000 mile mark. When you would be traveling around 20 mph and traffic would slow down nearly coming to a stop and then speeds would pick up back and you began to accelerate it would shift with hard thud into gear. Also when placing the car in reverse from park or from reverse into drive it would lunge forward. When at a complete stop and slowly removing your foot from the brake it would lunge forward as well. We have taken it into the dealership for these issues a minimum of six times with the following outcomes: 1) cannot duplicate issue 2) then duplicated it was a software issue and they updated the software 3) this is just how the transmission shifts - this is normal. The same issues are still occurring and more consistently with no resolution from two different Cadillac service departments. Then two weeks ago the main screen for audio/thermostat/ navigation went completely black while the car was on. Could not control any of the audio, thermostat, navigation - tried pressing the home button, controls on the steering wheel. I took a video of this for proof it happened because I knew they were going to tell me they couldn't duplicate this. In addition, the bluetooth would disconnect my phone intermittently then reconnect a few minutes later all on its own. The thermostat display will say its 76 degrees but will blow cold air on my morning 20 minute drive to work. This is our second Cadillac Escalade esv. Our first 2004 is still on the road with my daughter now driving it, I wish I would have kept it instead of buying this one as we have had nothing but problems with it. My husband and I have purchased 5 gm vehicles since 1995 and are so disappointed that our most expensive purchase to date is riddled with issues.
