I did 3K changes back in the dark ages.
I can't imagine that the typical Hyundai really need its oil changed every 3750 miles just because one lives in a major metro area.
OK, VW recommends 10K OCI across the board- or did when I worked for them. They are also getting a reputation for premature cam follower wear. I don't believe this would happen if the oil were changed more often.
The engine in the OPs Sonata is DI. Somewhere there are pics of a VW DI engine that is a mess. A few extra dollars to change the oil shouldn't be a deal breaker, and may very well help the OP in the long run.
Also, keep in mind that when cars are sold, low maintenance, high reliability, and warranty protection is stressed by the sales staff. All the owner needs to do is look for the asterisk in the owners manual. *
* All the stuff the sales guy told you about low maintenance requirements doesn't apply to you Mr./Ms. Customer. Don't feel bad, it only applies to those who drive in ideal circumstances (no dust/hills/stop and go traffic/heat/cold/high speeds.) In other words no one- you have plenty of company. Please see the Severe Service Requirements. Yes, this means you.
Those conditions are listed in my manual (without the sarcasm/humor.) My maintenance costs may be a few dollars higher than most folks, but on the other hand my cars never "assume the position" i.e. the tow truck. Seems like more than a fair trade.
