The wiring inside of the engine was chewed through by rodents. I drive the vehicle every day and it was serviced two days before. After performing some research, i found out that toyota and other companies use soy based products to make wiring. This apparently attracts rodents as it is basically food for them.the vehicle was parked in front of my home in a marked parking spot. I have parked other (older) vehicles in…

I started the 4runner and noticed that a few of the warning lights were on (abs, brake, & a few others i can't remember).

I decided to pull over into a parking lot and check under the hood. That is when i noticed a squirrel…

Toyota knowingly uses a soy based wire coating that attracts rodents. Something chewed through the wiring harness making my vehicle shake uncontrollably and act very strange. This is a huge safety concern because what if the damage was only partial and then through normal use like highway driving the wire fully comes apart disrupting any and all safety features

Toyota uses engine wiring that has a soy based coating. This encourages rodents to chew on them. We were camped (parked) and when we tried to drive the car it shuddered and the check engine light was on along with several other indicators. The car was running on five cylinders. We managed to get it to a toyota dealer who told us of bite marks and droppings. In researching this on line we found reports of this…

The day after we purchased this 4runner in october 2015 the [redacted] stopped working and when we took it back to the dealer they said that rodents had chewed through the wire housing connected to the drive train. Initially they were not going to warranty the issue but after further aggressive discussion by me it was covered. Apparently toyota uses a soy based spray or coating on the wiring that attracts rodents.…
