Wiring problems of the 2017 Kia Motor Sedona

Headlamp wiring harness defective. Low beam inoperative. Happened ad I was driving on vacation. I've read several blogs about same issue with other owners. No recall has been issued. My vehicle is 4 years old.

When I bought this car I was not given any warnings/information about the edible wiring in the auto even though there are numerous complaints and lawsuits about this problem. I could find nothing in the provided literature. I am a 73 year old widow and I had researched this car. It rated high for safety. I had to have a safe car. In February,2018 while I was on the road warning lights about abs appeared and the rear washer did not work. Diagnosed as chewed wiring. The dealership said not their problem! a few weeks later the car stalled on a highway and warning lights said abs and the cruise control did not work. A few minutes later the check engine light came on. The car fell to pieces as I was driving. Again diagnosed as chewed wiring. Again had it repaired at my expense. I researched and spent several hundred on repellants, etc. I had inside the car and all around the car surrounded with everything I could find. I called an exterminator but he saw no evidence of rats. Possible squirrels. Game cam took pictures of raccoons. Thought maybe I was safe. Two weeks later no water to front or rear windows. Dealer said about 8 inches of the water hose had been eaten. My previous car (chevy uplander 2008) sat in the same place for over 3 years and no wiring problems. Research showed most cars today made with soy-based wiring that attracted rodents. I am not safe driving this car. There were no warnings about a know problem. The dealer denies all responsibility and the manufacturer customer complain department will not return my calls. When I call them they say "not their problem". I say it is their problem!! I want a buyback or at least wrapping all the wiring with repellant tape, refund of all money spent in repairs and preventatives, a promise to fix any future damage and a monetary award for all my stress and inconvenience.
