Toyota uses new green (environment friendly) wiring that is tasty to rodents and other pest- they are aware that it can attract animals to eat the wiring and electrical systems on their vehicles and refuse to cover the damages incurred on the warranty - they refer the customers to seek monetary aide from their insurance company - in my case it was $3000 in damages to my vehicle for a rat eating the wires /electrical system. My insurance paid for it - but how can I be assured it will not occur again. ?? Toyota needs to be responsible.
