I'm inclined to believe it's
I'm inclined to believe it's the type of wiring and/or the design of the car (easy access for rodents). Just happened to us again this morning - 4th time! We had a Chev Tahoe and an Acura MDX parked in our driveway for 20 yrs. Never had a wire chewed. We now have two porsches (2017 & 2019) - same driveway. Each have been chewed twice. Maddening and expensive.
