Three different time, the car was parked overnight and would not start the next morning. It had to be towed. I was told that rodents had chewed through the soy based wiring insulation in multiple areas, including the fuel tank pressure sensor, the fuel hose. The mechanic could not offer me any concrete solution to prevent this from happening again and I fear a problem might occur while I am actually driving.
