seems to me what they are describing is major shaking of the motor. I had this sometimes with my old Suzuki SX4 DDIS 2.0 (2013). That was a diesel. Something went wrong at the startup and the motor was shaking heavily. I just turned the car off and then back on and it was gone.
With respect to marters eating on the cables .... as soon as I read that I went to have a look at my car. No damage yet.
Back in the days when I still had my Suzuki I mostly had problems with mice. I even had a mouse who was living in the air filter of my Suzuki. When I went to service my car they found a nest and a bunch of empty hazelnuts. I then used some metal mesh to block the entry to the filter. For the rest of the time I had that car I had no problems with damaged wires etc.
I also tried ultrasonic rodent repeller for the car but I imagined that I was hearing it myself when I was lying in my bed. Also my cat might hear it as well. And all the other animals living in my garden. So I got rid of it. These days I have a constant beep in my ears (tinnitus).
