Better hope its the rodent.

I think what defines the harness failure issue and affected models was the use of "eco-friendly" bio degradable wire insulation.
That stuff just degenerated while in the harness over time.
The new harnesses avoided the 'eco' stuff.

Hope the 'gecco' helps pay for the 'rat'.
