Hey folks, my SXP recently had screeching noise from the engine when I start the engine first thing in the morning, it lasts about 10 seconds then fades away (

My Telly's been in dealership for a week, but they could only duplicate the noise for about 1-2 s which is not long enough for them to find the source, the past week in my area was not cold enough though. They also shared the video with Kia regional engineering and they had no idea about this, just ask the dealership to replicate the problem... Dealer will try it one more time tomorrow morning (will be below 30F). BTW, dealership says that belt, tensioner are in good shape.
I have a 2021 SX Prestige and this has been happening to mine for the past 2 years when it gets cold out here in Western NY. I had the belt replaced and a crank pulley. Neither of which worked. I was able to video the engine compartment while it was squealing and sent it to KIA. They called me within 2 days and had me schedule another appointment with my dealership, and even gave me a case#. The dealership had it for a week and were able to diagnose a noise and heat coming from the A/C Compressor. They ordered a new compressor and it is currently back there again getting it replaced. I will have to hope this is the fix to the squealing in cold weather. The video I shared was after work one afternoon and the temp outside was 38 degrees. I was surprised to hear it, and how it lasted so long. Today is 12FEB24
UPDATE: Well, today is 13FEB24 and they replaced the A/C Compressor! I went to pick it up during lunch. About 36 degrees. They left it outside all night after they "fixed it yesterday. When I started it to drive off the lot, it immediately started that squealing again. So now we know, that the A/C compressor is not the problem. I am now driving a loaner car until they can figure it out. Hopefully get the KIA Engineers involved ASAP!! My loaner is a 2023 KIA Forte GT-Line. It's nice, but it's definitely not my beautiful Telluride SXP.
UPDATE 2: May 24th, 2024 I was told that KIA was closing the case because they could fine the cause of the squealing. "Bring it back next winter so we can try this again, they said. Well, I'm going without my Telly for 4 months again, The issue is still on record, just in case the engine decides to seize up, or worse. They did, however, reimburse me for 3 months payments. Noise is still there at 38 degrees and colder. I have noticed that if =you rev the engine while its squealing, it stops and starts at different RPMs. No change in sound, however.
