Mice and-or rats chewed wiring under the hood of our 2005 Prius, making the car un-drivable. We must replace the major wiring harness for the hybrid system as well as other wiring, which will be expensive. The Prius is 9 years old, and this is the first time that rodents have chewed wires on any of our cars. We found a rodent nest on top of the engine in early January, along with chewed insulation on some wires. I taped the wire damage that I found then. Apparently cold weather since then caused rodents to take refuge in the Prius. We live in a Dallas, Texas, suburb.
Do you have any ideas on how to keep rodents from chewing wires on cars that are parked outside? We park our cars in our driveway year round.
