Usually a squeal is associated with an accessory belt or one of the devices it drives. If the belt is loose or a pully is failing the squeal develops.

Default Sounds like mine when it happened. Could be the VBelt and/or vbelt tensioner.

Mine was the cause of a bad tensioner...dealer replaced the tensioner and belt and solved the squeaking!

Dealer changed out the tensioner and vbelt, as they diagnosed it to be the issue.
