Chances are the serpentine belt is either loose or contaminated.
First, with the engine off, open the hood. Inspect the belt for anything that may cause it to slip. For example, engine oil or coolant may be on it.
If the belt is clean, confirm it is tight.
If the belt is tight and clean, there is a chance the idler pulley is failing. There was actually a service bulletin related to this. Apparently, these vehicles have faulty idler pullies that fail and squeak.
An easy way to determine if it is the belt or idler pulley is this. Get a small cup of water. Start the engine. Make sure to wear old clothes and safety glasses.
With the engine pour a small amount of water on the pulley. If the sound changes, then the belt or tension is the issue. If there is no change, it is likely the idler pulley
I attached a pic below with the belt routing.
Let me know what you find or if you have other questions.
