Yesterday morning when starting my 2014 4runner the trac off light stayed illuminated along with the check engine light. I took the vehicle to the dealership and it was discovered that the vehicle was damaged by rodents (chewing, droppings). An electrical wire had been completely chewed through. I turned the damage into my insurance company but am out a days work, $50 deductible, $100 deposit for rental vehicle and $5. 10 tax daily on the rental. I believe this is all due to the soy being added to the vehicle electrical wiring (and anything else that is soy based) literally ringing the dinner bell for vermin.
