Warnings problems of the 2017 Ford Edge

The rear camera started to turn into a blue screen and sometimes it looked like static. We were told to go to Ford to change the camera (2020 or 2021?). After paying over $900 to fix the camera it broke yet again. We were 3 months past the 2 year warranty and was told if we wanted it fixed we would have to pay again. Now sometimes the camera works when backing out and sometimes its just solid blue. It is available for inspection upon request. This is risky because sometimes there are blind spots when turning our heads to ensure we are not going to hit a pedestrian. Also it takes me twice as long to reverse park due to having to use my mirrors to see the lines which causes drivers to honk or appear restless because I'm not fast enough which could cause me to crash into a parked vehicle. The problem has been confirmed by a dealership which is why they told us to replace it, but now they want us to replace it yet again. No warning lights. The vehicle no longer detects if objects are nearby. This happened shortly before the camera went out. They quoted us on fixing it and we refused due to cost. The vehicle drivers seat cooling and heating no longer works. It works for the passenger, but not the driver. This happened in 2019.
