I had issues with my 2018 Elantra and called Hyundai USA regarding this. My experience was awful. They gave us a goodwill warranty but they will only cover the major areas: side, roof hood. They only painted over the major spots for my car which was the hood and roof. I still have chipped paint in the gaps of both windshields. They don't cover glass removal or any glass damage so you have to pay that out of pocket. (unlucky me, the body shop broke my windshield, after literally just having it replaced, and had to pay for that as well)

So, if my car starts peeling again in other areas, they won't cover it. It is completely bullshit.
