Why is my Kia Picanto engine making a high-pitched noise?

I have noticed that my Kia Picanto's engine has been making a high-pitched noise. It happens when I first start the car and also when I accelerate. What could be causing this noise and how can I fix it?

The high-pitched noise could be a sign of a worn-out drive belt. I would recommend taking your car to a mechanic to get it checked and replaced if needed.

Another potential cause could be a faulty alternator. If the alternator is not functioning properly, it can cause the drive belt to slip and create a high-pitched noise. It's important to get this checked and fixed by a professional.

It could also be an issue with the AC compressor. If the noise is more prominent when the AC is turned on, then it could be a problem with the compressor. Get it inspected and repaired by a qualified mechanic.
