update:
this morning went to garage to check my beutiful Sonata that left me frustrated yesterday. Tried the fan. What do you think? Of course it worked.
Took it out to try. Promissed snow storm calmed after the nigh and snow "collectors" continued good job. Decided not to go to the Dealership even everything was arranged.
Kind of no proof. But I had photos and vid with engine on, defroster on fan on full and no sound.
After few minutes drive the heck stopped... Ahha... I directed to garage. On half way it started stopped few times. Of course when entered the service it worked

.
But Service manager was advised by general manager about my visit. I told that I have a video proof. He refused it and told that they have to check it and SUV loaner is waiting for me.
We had a nice conversation then he went to check it again. Car is on the FAN is down.
This is all the news for now. They should call me...
One mo thing ... I mentioned that when came to garage yesterday with fog in the car a burning plastic smell near the hood was barely noticeable. Not in the cabin at all.
I know that FAN problem on recently purchased Sonata was brought here in November with a situation much worst than mine. If the OP is somewhere around here please provide a link to your thread I want to see full story again and bring it to my dealership. I can probably find it somehow (think it was in November)
