This isn't so much about
This isn't so much about Hyundai ensuring their owners get the "correct" parts, but in ensuring Hyundai sells the part in the first place - to make the profit. As they are new to the volume game in the U.S. Hyundai is beginning to experience what the entrenched brands have been dealing with for many years - their vendors selling their excess parts through other channels. Most car manufacturers make their profits thru parts sales - because vehicle sale profits cover only the cost of advertising and incentives. It's the old "give away the razor to sell the blades" strategy and when someone else is selling your blades, you react.
