Once you take off the dashboard, your real problem begins. Applicable to almost any car any brand.

If it is not serious, just forget about it. Many times in my case, the sound just disappears by itself after 2-3 months.

If it can be rectified by yourself, just diy. This is better because you know what you have done to your car.

My 2011 persona had sounds at the back, after several months they disappeared. Now after 6 years, not a single sound can be heard, only normal wear and tear. Fuel consumption is ok, not great, just a little bit higher than honda city. But handling far better than other cars.
