Why is my BMW XM emitting a strange noise?

I've noticed that my BMW XM is making a strange noise whenever I accelerate. It sounds like a high-pitched whine. What could be causing this and how can I fix it?

It's possible that your serpentine belt is loose or worn out. This could be causing the strange noise you hear. I recommend taking your car to a trusted mechanic for a visual inspection and replacement if necessary.

Another possibility could be that your wheel bearings are worn out. This can also cause a high-pitched whine. I suggest having your bearings checked and replaced if needed.
