If what I am hearing is true. GM and other car manufactures have a huge issue by using soybean lubricant(?-soy based insulation) on wiring insulation (or soybean based insulation). Rats consider the smell to be food and eat the wire insulation creating shorts. One ate up my wiring harness --disabled car -- and expensive repair. It is great to be environmental with vehicles but creating a rat delicacy under the hood is a bit ridiculous. ---- GM did not warranty -- and I understand they have knowledge and significant issues with this manufacturer created problem.
