The most common cause of this issue is a worn out or faulty serpentine belt. It is important to get this checked and replaced if necessary as it can lead to more serious problems if left unchecked.

J

Another possible cause could be a loose or damaged heat shield. This can create a rattling noise when the car is idling. It is important to get this fixed as it can also affect the performance of your engine.

S

If you notice the noise is coming from the exhaust, it could be a sign of an exhaust leak. This can cause a loud grinding or hissing noise. It is important to get this repaired as soon as possible to avoid any further damage to your vehicle.
