my எக்ஸ்யூவி300 டீசல் when ஐ start moving or raise acceleration. ஐஎஸ் it normal? இல் ஐ am hearing whistle sound inside என்ஜின் cabin

I assume you are moving on concrete tiles or some similar surface. If yes, the sound is there and it is a road noise generated when such a heavy vehicle move over such surfaces. I have also experienced the same over such section of roads. However, the sound is not there on any other surface such as normal tarmac road, gravel, grass etc. So far the only place i have experienced the same is concrete tile paved roads, and I always experience the same when entering such section if roads. It is not an issue with the vehicle.

That the turbo acting while pressing the accelerator...dont worry thats normal..that sound is also on the scorpio. I also own an xuv300 which has also the same sound...I have a doubt as well, does your car has a rattling noise from front when you go in any rumbled road? because I'm having issues with the same. Plz help if you could I'm really depressed by that noise. They say that this noise is in every vehicle
