I now have just over 1900 miles and almost two months of ownership and I'm still discovering features. Very likely because I never read the manual 
Some things that I didn't know it had that I really like...
(1) I recently noticed when backing out of a parking spot and the collision warning alarm started chirping but the other vehicle was not in view of the camera, the dashboard has an animated red arrow in the direction of which way the object in question is moving. I've never seen that on any vehicle before, not even my Tesla. This was very helpful as my view was obstructed by a large SUV parked next to me.
(2) The "auto" A/C control has three blower settings, low, medium, and high. I find this great to warm up or cool down the car quick if I forget to remote start and then set it back to low for a quieter driving experience
Something I considered a selling point for the Limited over the SEL Premium, but in practice I never use is the turn signal camera on the dash. I find it substantially more time consuming to look down and through the steering wheel and focus my vision on the small video to determine if the adjacent lane is clear for a merge. I feel in practice its actually an unsafe option for me especially when it just takes a second to glance into the side view mirror and get my eyes back on what's in front of me. I'm sure my height and seating position plays a role in how useful this feature is. I think if Hyundai used a larger image and moved it to the center screen (Bose) so it's unobstructed by the steering wheel (like Tesla) it would be far more useful.
Although entry into and exit out of the SC is easy for me, I thought I'd miss the step rails which I had on the Tacoma it replaces. In fact do miss the step rails though not for actual stepping as its unnecessary with the SC, but the rails would give it a more trucky look.
Driving agility, handling, and ride quality. Overall I'm very happy with it. The ride quality in terms of absorbing bumps and rough roads and light trails is great and I'd compare it to a quality SUV. The handling and agility are also great, much better than my Tacoma and CR-V. It's not without fault though and the one fault I note in this category is how jerky the shifting(?) is. At very low speeds, especially stop and go (low speed), it's a jerky acceleration. From stop to driving speed (30mph ~ 45mph) is a little jerky on the shift points reminding me of a manual transmission. This is my first Turbo as well as first DCT so maybe its normal. The brakes are quick and take less foot power to apply more break power than my Tacoma. This has kinda f'd up my driver rating with my insurance beacon which measures my driving performancing.. I'm seeing hard brakes all over my drives now LOL Oddly I'm also seeing more incidents of hard acceleration, I think this is do to the initial lag on acceleration followed by a sudden snap forward into acceleration. The funny thing is my insurance company measures 'hard acceleration' as a negative, but my overall rating on not being a speeder is excellent. I'm still saving money with the beacon though.
I absolutely love the retractable tonneu cover. In time I don't know if it will be more durable than the Bakflip X2 Revolver I had on the Tacoma, but it is 100% more comfortable and friendly to operate and the X2 was very easy to operate, but often got burnt touch it as the heat made the aluminum blades scorching hot to the touch.
The most important thing I wanted from the SC and it has delivered 100%. It's compact and agile in parking lots
I go to Costco & Walmart every week and navigating those places was very difficult in the Tacoma especially with Miami drivers, I never drove my Tesla to those places LOL
One thing I'm starting to hate about the SC. All those darn creases in the body styling are in typical strike zones. I discovered a dent in one of the rear doors, the center of the dent is to the right of the vertical crease line (near the edge of the door) with the dent effect ending at the crease line not on the crease so there may be hope it can be repaired with painless repair.
Overall I'm very happy with the SC, though I only have bad things to say about Hyundai customer support LOL
