I’ve seen a lot of such reports. I believe Honda has been using such “natural” “eco-friendly” wire insulation for several years.
Oh - and it is not in any way covered by manufacturers warranty - even if you drive a brand new vehicle home and a squirrel or rat were to get in it on day #1 - you are out-of-luck. Even though manufacturers are absolutely aware of this problem.
It is just another example of why eco-fraud is really bad.
You are correct. Not covered by warranty and they turn a deaf ear when owners complain. Well, class action lawsuits are in the making and we’ll see what happens.
