Why is my Nissan Micra making a strange noise while driving?

I recently purchased a Nissan Micra and have noticed a strange humming noise coming from the front of the car while driving on the highway. It seems to be getting louder the faster I go. Any ideas on what could be causing this and how to fix it?

It's possible that the noise is coming from your tires. Have you checked the air pressure recently? Low air pressure can cause a humming noise while driving.

Another possible cause could be a loose heat shield on your exhaust. This can create a rattling noise while driving. I would recommend taking your Micra to a mechanic to have it checked.

I had a similar issue with my Micra and it turned out to be a faulty wheel bearing. Have a mechanic check the bearings and replace if necessary.
