Why does wheel squeaks when turning? How do I tell if power steering fluid low?

Hi, a 2018 MB GLC300 uses electronic power steering - meaning no fluid. I don't know what to tell you about the screeching -- a physical inspection is needed. Perhaps consult a shop near you. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
