Unhappy Jet Engine Whine just after Startup (Not Rattle mentioned elsewhere!)

Steps to reproduce:
1) Start Car (reproduceable with A/C on & off)
2) Wait for wind-up whine (starts out low, then speeds up, then stops) - I attached MP3 and Wav files in .zip attached so you can hear the noise - recorded on my phone). Similar sound posted by someone else on Youtube (found link on Cargurus site):
. Listen to first six seconds. My sound file has the noise for a slightly longer period.

My car started doing this about a week after purchase. It's been consistently doing this every morning. In high elevation, colder climate the sound is louder and longer. Car's been to service 4 times. Service Trip summary:

1) Returned as cannot reproduce
2) Replaced Starter (even though sound happens After start)
3) Replace belt tensioner
4) Service stop, tech said he would contact his rep - rep said no fix "it's normal- related to component in timing chain". (Huh?)

Service tech said he's heard a few of the 2012 Elantra's with this noise. I feel like I have a lemon. Anyone have similar noise and what's been done to fix it?

If you do some searching in this forum it is a VERY well known occurance you'll find. Don't worry about it, it is completely normal on this car. "All systems go, prepare for launch!"

Perspective, try putting things in it sometime.

5.4FX4: I searched the 2011 - Elantra forum and only found rattle and click noises. This is a start up whine that sounds like bearing noise or belt noise. Are you able to post a link to elsewhere in the forum that has this noise. The rattle is not a concern, it's the wind-up noise that's worrisome. Here's another video on Youtube that has more easily detectable noise:

Yep, the longer, louder version in video 2 is closer to what I get every morning (you can hear a bit of it in video 1, but it's about 6 seconds in and not as long. It is disconcerting indeed.
