Warning lights triggered snd certain electrical vehicle functions affected. Lexus Plano dealer states that wiring is soy based and destroyed by rodents attracted to the wiring and chewing it with result that critical vehicle functions affected and lights, brakes, etc. may not work resulting in crash. Wanted more than $10,000 to rewire vehicle and refused to make repairs under vehiclesa warranty. Apparently common knowledge that Toyota and Lexus are using soy wiring that attract rodents and other animals to eat the wiring. I believe that crashes may be occurring because of chewed through soy wiring and misdiagnosed as driver error, brake, failure, fires, lights out, or other causes because no one is investigating wiring that caused crash. Wiring should be recalled as it poses death, injury, and property damage risks with manufacturers and dealers knowing of the defective wiring and of the risks but intentionally hiding the information, failing to warn, and then making huge profits from the expensive over-priced repairs that are unnecessary if proper wiring is used. We have dealer invoices and repair estimates snd other communications.
