 Apparently gm uses peanut oil to lubricate wiring so they can more easily insulate, etc (accorging to the gm dealer). this attracts rats and mice which chew up the wiring - potentially impacting sensors and other items controlling cruise, stability/traction control, and any number of electrical systems that the driver may be relying upon for safety. i actually had map sensor wires chewed up that disabled my stability/traction systems and inhibited engine performance. luckily for me it happened in my driveway rather than on the highway. dealer claims it is not warranty item even though caused by a process that gm elects to use in building the vehicle. this could impact any/every vehicle that gm builds with use of peanut oil (may indeed be all of their models). *tr
