The dealers are moving to the max miles allowed in the manual, and Corporate is pushing the decision solely to the dealerships.
I bought my '19 in Nov '19, but according to the door plate, it was made in Feb '19. So in Feb '20, three months after I bought it, with only 2k miles on it, I called the dealership and said my oil is a year old - can I get it changed? They said sure, bring it in. I did, and they did - but they used conventional oil. Not full synthetic as called for in the manual.
I wrote to Genesis corporate and they said it was up to the dealer to use whatever they wanted. Corporate said that the car came with full synthetic out of the factory and that is what they recommend using, but the dealers can use whatever they want. This pissed me off and I've been doing my own oil changes since, unless I have to take it in for something else - then, I supply my own oil.
What bugs me is that the dealer won - by not doing what they should do, the net effect is that they no longer have to pay for my oil changes. Corporate doesn't care, and the dealers get top dollar selling a luxury car with little service expense to follow.
