Start-Up Issues?

Anyone have trouble with their Elantra Sport not starting on the first try? My '17 has 3,500 miles on it and intermittently takes a second try to get it running. Either the engine immediately dies after the starter disengages, or it takes a few turnovers for it to fire off. This has happened 4 times (two times of each scenario), always after the car has been parked for an hour or two (never happens after sitting overnight).

Before this, the RPM used to fluctuate - almost flutter - for a few seconds when the car first started up in its high idle stage.I always assumed it was the A/C kicking in, but now this has turned into something serious.

Took it in to the dealer today, and they couldn't replicate the issue or find any stored codes. Recommended I drop it off when they have a service loaner available so they can consult Hyundai techs over the phone. Apparently that's the only way they will replace parts that haven't outright failed, as in my situation.

Has anyone had this issue, or have any ideas what's causing it?

Wanted to bring this tread up again. Still have an issue with the car not wanting to fire off after a warm start. In more severe cases, the starter will run for about 5 seconds, disengage, and cycle again if the car hasn't started. In one case, the car maintained about 500 rpm between cycles. Really feel like I got a lemon here. Link to video of a weak start below.
