squeaking sounds when start up in the morning(Video included)
Hey Guys
Past couple weeks I am start hearing squeaking sounds when start up in the morning. What do you think can it be? My manufacture warranty expires in two weeks and was wondering if I should take it in before my Chrysler warranty kicks in. Any suggestion would be nice, or am I being paranoid?

Mine does EXACTLY the same thing. Dealer thought it was the SC clutch/pulley, so they warrantied that. Still does it. I have both new belts. Im now assuming its one of the tensioners.

I am going to my dealership to convince them to put SC clutch and a flange. Thanks, I also thought the idle pulley, but after it warms up, noise disappears.

My dealer replaced both my SC clutch/pulley/flange. The noise is still there. Mine too goes away as it warms up. It has to be a tensioner, or idler pulley
Heres what mine sounded like before the new sc components. Mine now sounds just like yours.

It's funny this issue came up. I just got my whip back from being serviced and I had that same issue. The mechanic found it was coming from the oil pump. He said it was real noisy when it started up in the morning. It usually goes away with a blip of the throttle. The oil pump tested good so they did not replace it. I would keep an eye on it because if the oil pump fails, so will your engine. So if it whines in the morning, make sure you hear it every morning before you drive off.

keep us posted I too have the same problem. It's only been 34 days since I bought the car. I always thought it was normal.

Mine does the same thing, and has been doing it since I got it 13K miles ago. I thought it was the small idler, but I am convinced it is the belt. With yours especially, you only hear the noise when a certain part of the belt passes by one of the pulleys(probably the small belt on the small idler on the drivers side). It is an irregular noise, and not consistent with a squeaking pulley.
To diagnose it, I sprayed carb/brake cleaner on the belt, and the noise went away instantly. It came back the next day of course, but I've done this 2 or 3 times, and as soon as the cleaner hits the belt the noise vanishes. I am on the stock belts with 75K on the clock, so I'm going to replace them in the next week and see if it goes away completely.
FWIW, I also tried spraying some WD-40 into the center of the pulleys, and the noise didn't change until the lube hit the belt.

When I bought my car, I had the same issue. Upon start up it would squeak for about a minute or so. They replaced the idler pulley and belt and the problem went away for a couple months. Now it's back and worse than before. 
If anyone wants to try this ...
Motorcycles often have a similar problem. With a higher performance bike, and belt drive, the belts often squeak very noticeably and annoyingly.
Belt dressing works for a minute and then fails.
DISH SOAP, like Dawn (What I've used on my personal custom) works for weeks at a time. Put it on the belt and let it dry up.
The logistics of putting it on a motorcycle drive belt I'll wager though are much easier than putting it on the idler pulley belt of our cars, but it definitely works.
My concern would be the motorcycle belt is a cog type belt so no worry about slippage ... THAT may be a problem with this belt.

that becomes interesting. any more suggestions? by all responds so far, I will have to change half of my engine to solve an issue Supercharger belt was changed 2 months ago, dealership didn't say anything about a belt tensioner, but it makes sense. btw. 170 views of my video and 10 responds.. not bad of a result i guess, but we got bunch of lurkers but people are afraid to post.
