Creta S (O) cvt petrol owners need help with below two points

I recently bought a Creta S Optional Petrol Automatic, and I want to cross-check a few things with other owners:

1.	When driving on rough or uneven roads, I hear a noise from the rear side. It’s a bit annoying — similar to the sound you hear when a bottle moves inside the bottle holder. Do you experience the same?

2.	Today I drove uphill and felt like the car was struggling a little while climbing. Maybe it’s because the car is new — have you felt this too?

I’ve driven only around 450 km so far.
