I have a 2020 Ioniq that I bought newly, so of course I was told my extended warranty will cover every kind of damage. Rodent damaged the wiring harness recently and the service department said my warranty does not cover it. I have read that many new vehicles have this issue due to the use of soy based wiring covers, I really think Hyundai could cover the wiring with some metallic mesh, I cant afford to keep replacing them.
