Are you sure? The warranty is on the car, not the owner. Almost all manufacturers (except Tesla) transfer automatically and are based on mileage.
Their much hyped 10 year 100K mile power train warranty is only for the original purchaser. Once sold the warranty reverts to a more standard 5/60K term.
Who told you that? Unless you buy your Hyundai new, or CPO from a dealership, the powertrain warranty is 5/50.
You have it backwards. Hyundai, KIA, etc will knock it down to 5yrs/60K for used car buyers.

Teslas new car warranty transfers as is to the new owner.
