The most common cause behind a high pitched noise under the hood is the drive belt. if it is worn out or loose, the wheels will slip, creating the noise. I would check to make sure the tensioner isn't bad. If it is, this could be causing the looseness. If the tensioner is fine, then just replace the belt.
A high-pitched squeaking noise while driving, unrelated to the brakes, could be caused by several factors. Common culprits include worn or loose belts, such as the serpentine belt, which can produce a squeak when under tension. Additionally, issues with wheel bearings, suspension components, or even tire noise can contribute to such sounds. It's advisable to have a mechanic inspect your vehicle to pinpoint the exact cause.
