I have an 07 SL that I purchased a month ago and a few days ago I noticed something squealing. it sounds like a belt but I'm really not sure. i really haven't looked into it yet. just wondering if there is anything I SHOULD be looking for or if there may be a known problem with something before I bring it in. Thanks

oh and I notice it pretty much all the time

 

Hopefully it's just your belts loose... check your tension my friend plus your tensioners. Look at your belts make sure they are not wet or deformed in any shape or form.
