Mice will not leave my 2020 Tundra alone. They ate through the main wiring harness, fuse block and into my heat/air system. The repair cost was $8661.20, of which Progressive paid $4454.65 and left me to pay the rest. Progressive actually told me I didn't drive it enough. I drove once a week, and according to them I should be careful where I park my truck. People, I'm retired, 100% disabled Vietnam Veteran, fixed income and just went through radiation treatment for cancer, putting me at risk for Covid. Toyota has never mentioned to me anything about soy based wiring.

I bought my new Tundra a week ago. Happy as can be to have a nice reliable Toyota truck. 1 week later starting my truck up in the morning had check engine light on, trailer sway assist malfunction, Collision assist malfunction.

Took it to the dealership and they say I have a rat problem at home and that rats ate my wiring harness. Not covered under warranty. I do not have a rat problem, I have a feral cat problem and have never seen a rat. I do not live near fields or Ag land, Im surrounded by asphalt and concrete in a condo complex. The dealership, however, is near the freeway and a miles long strip of field that my truck was parked right adjacent to while on the dealers lot.

Not their problem they say, the truck was drive able when I paid over 50,000 the week before.

I had to pay 500 for my comp deductible and use my insurance to get my truck repaired.

A little research later and I find out that this is a common problem for Toyota and there have been law suits, even class action lawsuits. Not necessarily to this dealership, but Toyota in general for using soy based covering on their wiring that is attractive to mice and rats.

I wish I knew that a week ago.
