Picked up and love our 2022 Tuscon Hybrid in October of 2021. Two weeks ago I noticed oil drops on my driveway. A week ago I was due for an oil change so I took it to my towns excellent service garage. I know the guys there. They did the oil change and said I have oil al around the "throttle' area. So with the oil stains on my driveway it was time to take it to Hyundai. They have had it since last Thursday and cannot find the source of any leak. They keep communicating with the engineers at H and do a diff test daily. Today is a dye test. WTF!!!!!!!!!!!!!!!!!!!!

You or your mechanics could just tell them exactly what is causing the leak.

I'm guessing if it was the known issue for a few Korea built Hybrids in 2021, a leaking oil pan, that would be easily seen. (as well as an easy fix)

There was one or two threads a while back about both an outer and an inner seal issue with either the tx case or tranny, or both. I'm leaning to it being a tx case issue. In any event, some reporting as experienced mechanic type posted about replacing the outer seal and it still leaked. The inner seal was not a service part, and the case is not considered 'serviceable' to begin with. And I'm at least 15% certain of everything I said, so it's all just a good discussion starter with the dealer. I'd be looking on here and the other forum though for any intel, as most of the mechs are not fully up to speed with the all-new Tucson design. But don't tell them that.

Before taking it in, lay down and measure location of a piece of paper to place and ID the type fluid (for proof and whatever component is involved)..

And just caught Tampa8's post, and Korean built ones had a run of leaky oil pans early on (too little sealant). The drip on a pc. of paper should help the mechs. differentiate motor oil from either tranny fluid or gear lube.

My Tucson 2022, after replacing the first engine oil, the oil leaked, so I sent it to the service center by tow truck and got it repaired,
but it is still leaking.

I have the same issue with my 2022 Tucson Hybrid. Took it to dealer for diagnosis. They did dye test and said they couldn't trace the leak. I do see droplets on the driveway and a wet area around the engine cover. I need to take it to dealer again. If anyone had it solved by dealer, please share the details.

Had a similar problem on my '22 Hyundai Hybrid. Oil on my garage floor. Went to dealer and they could not find any leak so they cleaned up the pans and sent me home. Several months later , during a regular service at the dealer, they said that the oil pan gasket was seeping and they would reseal it under warranty. Hmmmm...at least the oil has not appeared on my floor since!

How long's it been since the repair?
I've done my share of tracing down oil leaks: it's sometimes a real challenge to sort out just where the oil is coming from. Unfortunately, our OP was a one and done poster. We have no idea what the issue was. All we know was that the dealer kept it long enough to frustrate the poster. That tells me that they were attempting to be thorough and track down the source. Beyond that, thanks to the fact that our OP never gave us any more info, the collective ca't be of much help.

Now since this thread is leaning toward oil pan leaks, there's another thread that addresses this issue: CLICKY
