Wiring problems of the 2018 Chrysler Pacifica

The back up camera only works intermittently. Sometimes the screens flickers as if it is shortening out. Other times the screen freezes, displaying the initial scene behind the vehicle for the duration of the vehicle being in reverse. Sometimes the screen is blank with only the guiding lines visible and other times it is completely blank with a statement at the top stating the back up camera is unavailable. This is a major concern for us due to having small children, going to the school, playground, etc. The dealership said they could replace the camera for $400 but the issue seems to be a short in the wiring somewhere. As the camera sometimes works. One of the pictures attached show the camera frozen with a white vehicle on the back up screen. The white vehicle that is displayed is actually in front of the van at the time of the picture. This is a screen shot from a video.

Water entering through front side of marker light and shorting out light and corroding wiring and switch. Also, breaking active grille shutter. Also shorting out bulb for the marker light.

I live in new york city and have had my Chrysler Pacifica phev for just over a year. About 6 months ago, I had (more) electrical problems causing the check engine light to be constantly illuminated. I took it to the dealer and the dealer found that my engine wiring had been chewed presumably by squirrels. They kindly patched up what they could find and sent me on my way. The check engine light came on shortly after that, just before a long vacation. I brought it back to the dealer today and without any pretext, the intake specialist said, as if it were common industry knowledge, that "the wire insulation is soy-based plastic and that's why squirrels like to eat it. " if this is the case and the fact is that a manufacturer is producing vehicles that within the industry are known to attract vermin, this must be inspected. I'm driving a car with giant lithium batteries, which if shorted could easily cause fire and death. Please don't let this go unaddressed.

Touch screen is not turning on. I have started my vehicle a few different times hoping will come back on, but no luck. Unable to get to any of the functions including backup came does not come on with is a safety issue in accordance, "the u. S. National highway traffic safety administration announced that it would require all automobiles sold in the united states built beginning in may 2018 to include backup cameras. " unable to use any of the climate controls, heated seats or vented seats, radio, uconnect etc. . All features unable to use do to black screen. This vehicle has been to the dealership multiple times with multiple screen swaps and continues to happen. I was told by the dealership humidity causes the screen to go black or not work. I addition, I have notified the dealership when changing out the screen please change all wiring harness. I do not know if this was ever completed or not. There is a short somewhere and without back up cam working it is a major safety issue. I will be driving and the screen will go blank. This has been on going for over a year since 2019.
