Starter problems of the 2018 Jeep Renegade

I purchased a 2018 Renegade about 3 weeks ago. Within a week of that problo began with remote starter that had been added prior to purchase that would unlock all the doors whenever vehicle was started using remote starter. I was extremely frustrated as that vehicle had issues from day one and dealer couldn't fix them. No offer from dealership to allow me to return it. So out of frustration I traded it in for a much higher cost vehicle in hopes the issues would be gone with a brand new vehicle of a higher price and package. Not so! from the first day about 2 weeks ago I started experiencing serious problems. Everytime I use the remote starter the vehicle shuts off whether I touch the door handle, unlock vehicle with remote, open door or enter vehicle if the first three methods didn't shut it down. In addition the uconnect 4 w/7" display started locking a week ago and would not let me turn it off, change temperature inside vehicle, even locked out the manual controls of heater/ac temps,fan could not be changed, radio stopped playing. No matter what I tried nothing worked. I had to pull over and shut vehicle off and restart. Within a mile down the road it locked up again and this time same problems with non repsonsive controls as well as the video display began flickering in lower left hand of screen. I waited till I got to my destination and shut vehicle off. When I came out to leave it was somewhat working again. Prior to this issue with uconnect the vehicle had been to dealership twice. First time they claimed they could not replicate 2nd time I was told the remote starter was a known issue since 4/2018 with no known remedy and the radio uconnect system was defective and a new radio was ordered but was backordered with no known date of availability. So I have a very expensive vehicle with just over 1,000 miles with serious and potentially dangerous issues with it.
