Town & Country Jeep Chrysler Dodge Ram

So disappointed with Levittown town and Country Jeep Chrysler Dodge. I just purchased 2 2018 cars. The touch screen, which effects every option in the car, is malfunctioning. As you drive the screen turns on and off, even when using the back up camera, causing me to almost have an accident with my children in the car. Their customer service is abysmal, they won't even give me a loaner until they solve the problem. When I explained what happen with the back up camera the manager told me that I am ultimately responsible for my driving. What the?!? So frustrating!
