NHTSA Complaint #11442485 — 2015 TOYOTA PRIUS

I bought this vehicle on July 3, 2015. When I took it in for an oil change in Dec. 2015, I was informed that there was a mice infestation and that the electrical wires and other systems were damaged, resulting in about $2,800 in repairs due to the mice chewing the wiring. I just took this vehicle back in on 29 Nov. 2021 because some of the systems weren't working properly, and they confirmed that a mouse has again chewed up the electrical system, again costing about $5,000 in repairs. I've just been informed by my exterminator that Toyota uses a wiring harness coated with a soybean based coating which is causing reports of mice damage in a lot of Toyota vehicles. We have 2 other vehicles which are not Toyota vehicles and have never had a single problem with mice chewing the wiring harnesses of those vehicles, although all are parked in the same area. The vehicle is currently pending repairs at Fred Haas Toyota Country in Houston, TX and will be there for at least a couple of weeks pending availability of parts. Electrical issues of this type can cause serious failure of safety features. Toyota has never told me that they use soy based elements in their vehicles that would entice rodents to chew the wiring or otherwise entice them into the vehicle. I do not have a report from insurance yet, but I have filed a claim.
