Rodent Damage to Ford’s Soy Wiring

Newer Ford vehicles use an electrical wire coating that is a more eco-friendly, soy-based material. But maybe it's a little too eco-friendly? There's been an uptick in owner complaints about rodents using the coating as a chew toy and causing thousands of dollars in electrical damage.

Ford is far from alone on this problem.

Toyota was sued because owners think this sort of damage should be covered under warranty. Toyota continually denies that modern insulation is any more appealing to rodents saying we are currently not aware of any scientific evidence that shows rodents are attracted to automotive wiring because of alleged soy-based content.

Honda owners were also tired of rodents using their engines as a playground full of chew toys. The plead plaintiff says his 2014 Honda CrossTour wiring was shredded by a rabbit, a rabbit found in the engine compartment by a Honda dealer. Delaney says the dealer provided a photo of the rabbit enjoying the soy wiring for lunch, but the dealer refused to cover the repairs under warranty, which left Delaney paying $765 for the repairs..

In the case of Michelle Martinez v. Hyundai Motor America, Inc., the plaintiffs say that when an owner takes their vehicles in for repairs due to chewed wires, the gnawed materials are replaced with more soy-based materials. A vicious ciricle ensues, and owners can spend thousands of dollars just keeping their cars running.

Subaru was sued in Hawaii because, come to find out, replacing a fuel line or running new electrical ain’t cheap. Especially when you have to do it again and again.

Tips for Preventing Rodent Damage

  • Regularly open the hood and inspect your engine for signs of rodent activity (so, poop)
  • When you move the car, look for any shredded pieces of wire coating or other material that looks like a nest that might have fallen out.
  • Clean all food out of your car, including food sealed in bags. This is especially important for dog food and treats.
  • Some have had success with putting mothballs, dryer sheets, or liquid peppermint in their engine compartments.
  • Wrap your electrical wiring in something rodents can’t stand.
