Toyota owners smell a rat, sue over rodent damage to soy-based wires


In California, Toyota owners have filed a class action lawsuit against Toyota over claims the car company’s soy-based wire insulation is being chewed by rats, mice, and squirrels.

The lawsuit alleges the pest-attracting insulation was used in many Toyotas from 2012-2016. Once gnawed on, wiring and electrical troubles ensue. Toyota is denying owners coverage under its New Vehicle Limited Warranty. The company claims that rodent damage can occur in all vehicles, regardless of brand or model.

Honda, which is facing a similar suit, says that rodents are drawn to chew on wiring in homes, cars or anywhere else significantly predates the introduction of soy-based wiring by several decades.
