2015 Belt Squeak/ Noise When Turning Off Engine

[kouskie]

I've got a 2015 SR5 with 56K miles and about 4 months ago most every (90%) time I turn off the car the belt squeaks for a second or two and I cannot for the life of me figure out what it is.

I have taken it to both the shop and the dealership and neither could pinpoint what the problem could be. I have a video of the noise and will see if I can get it posted.

Any help would be great!

Here is the link to the video of the issue I am having. This issue only happens when turning off the car, not when it's sitting idle or in motion...
