Squealing in a Renault Megane can be caused by several factors, including worn brake pads, which may squeal when they are due for replacement. Other potential causes include a worn serpentine belt, which can produce a squealing sound when slipping or damaged, or issues with the wheel bearings. Additionally, low fluid levels in power steering or a malfunctioning alternator can also contribute to squealing noises. It's advisable to have a qualified mechanic inspect the vehicle to identify the exact cause.
