The serpentine belt has been replaced twice which caused dead battery, water pump and power steering motor replaced. I think the problem is pulley misalignment or the belt tensioner
Squealing and belt failure multiple times, unknown origin. Have had into the shop at least 10 times

Made those terrible noise that sounded like a huge cricket. Crayon on the serpentine belt was a temp fix. Ultimately we replaced belt and pulley it's been fine ever since.
