Trunk Wiring problems of the 2016 Ford Edge

I bought a 2016 Edge titanium last year. The wrench engine light came on this week. When I took the Edge to the dealer, the first thing the dealership did was look into the engine compartment and explained that my wires and sensors were chewed by rabbits or mice. I learned the electrical wiring system is soy based. I asked if the dealer could replace the wires and sensors with non-soy products and was told Ford does not make a non-soy based wiring system. I live in colorado and we use our vehicles out side for camping, vacations, and driving. Animals apparently love soy. There are plenty of opportunities for animals to destroy wiring systems where I live. This cost me $1,050. This also happened to my brother who lives in missouri. He had a 2016 Ford fusion. It was parked in his driveway 4 weeks. He could not start his car and had it towed to his dealership. He was informed he had to have his electrical wiring and sensors replaced, which cost him $2,000. This never happened to me before, or my brother, and I have purchased Fords since the 1970s. I feel Ford should offer the option to replace these defective wiring systems with a non-soy product and reimburse us for this damage. When the dealership is done with the repair, I will be happy to provide the repair bill.
