Twice within a one week period, some type of animal, most likely a rodent, ate through my power steering harness rendering all safety features on the car inoperable. The car was undriveable as the steering wheel could not be turned. The dealership advised that the wiring for this vehicle is made of soy which is a food source for animals. Honda is aware of this issue and now stocks rodent tape to use over the wires. Honda should not be building automobiles with soy based wiring. No other vehicle sin my lot were affected--just mine because it was a Honda. I have the harnesses from the dealership showing where they were chewed on. The dealership is aware of other customers with this same problem. It is most definitely a safety hazard. Wires that were not completely chewed through could fail while the car is operating causing injury and/or fatality. This issue has existed for several years with Honda and they have not changed their manufacturing. Class action lawsuits were necessary. These vehicles should be recalled for replacement of a power steering harness that is not made of soy. My complaint to Honda was given a case number, but I have not been provided any status even after calling for same.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Honda Civic Si verdict →
