A friend brings Mark his new 2023 Hyundai Santa Fe because the horn stopped working and wants to know what's wrong with it before wasting his time at the dealer.
It’s a supplier issue the new horns has a totally different part number according to Hyundai the horns fail due to moisture and corrosion buildup inside them so the dealership should replace with a new part number if your hold fails again they are probably replacing it with the same defective part number
I know Tier1 suppliers would never let more than a few hundred defective ones get out the door - let alone years worth - this is some CAN bus related issue
