ToddGak Posted April 5, 2020 Share Posted April 5, 2020 The check engine light came on the other day. It was the knock sensor. We took it to the dealer for warranty service and was told this is a frequent problem with the redesigned Navs. We were told that the shielding in the engine wires contain a soy product in the formula which is attractive to mice. If we had an older car the mice wouldn't have chewed on the wires. Since mice damage isn't a considered warranty issue, we ended up paying $1500 in repairs. We ended up finding teeth marks on the foam "lincoln" plenum cover and the mice even filled one of the 'quadrants' of the Lincoln logo with urine. Gotta give the mouse some credit for style points. We did end up killing it and now have electric shock traps in our garage to avoid this in the future. Word to the wise - buy a few mouse traps for your garage.

Black Label Posted April 5, 2020 Share Posted April 5, 2020 A case can't be made that putting something on the wires that attracts mice is a manufacturing defect? Lol. Thanks for the heads up. Quote Link to comment Share on other sites More sharing options...
sullynd Posted April 5, 2020 Share Posted April 5, 2020 (edited) My sister had the same thing happen to her Fusion, she was told the same thing by the dealership (Soy etc). Insurance covered it (after deductible). Edited April 5, 2020 by sullynd Quote Link to comment Share on other sites More sharing options...

akirby Posted April 5, 2020 Share Posted April 5, 2020 Mice eat the insulation off every kind of wiring. You have a mice problem not a car problem. Quote Link to comment Share on other sites More sharing options...

I don’t doubt the new wiring might be more attractive but the solution is the same either way - get rid of the mice. Quote Link to comment Share on other sites More sharing options...
Andy L Posted April 6, 2020 Share Posted April 6, 2020 I had rats damage 3 vehicles and a boat around 2002 while we were out of town. $6500 worth of damage. I have rat traps in my garage now at all times. I think this can happen to any vehicle. 1 Quote Link to comment Share on other sites More sharing options...
