normal because the disc rotor is imba. try to claim from SC stating your issue. most of us here have claim rotors to solve the issue and approved.

Would be glad if you can share some picture here.

Welcome

I am waiting for my Preve too.

check on nearest SC. usually disc rotor problem .

Btw congratulation , finally u get your new baby 

Metallic E. Brown and as what i saw under sunlight like gold shining colour so i pick that.

My house got metallic silver car and black already so don`t want the silver.

Owh ya how do you describe steep slope. Because when i test drive the preve at slope it did not roll back. How steep is your slope ?

If you are KL people the slope got as steep as Mid Valley IGB Tower when going up to parking ? ( Because as i know i drove many auto car only that place parking when climbing up will roll down because its too steep. )

Others like Sunway, Subang, PJ Up Town, and many more steep slope i never experience roll back before.

I scare behind people follow too close then the car roll back then there comes problem. Last time at Mid Valley there got people follow kissing my car buttock so near lucky no roll back. Some driver tak sabar sabar rushing and like to follow people near near.

Congrats bro and enjoy your ride.
The sound may cause from brake disc rotor..common problem for new car..send back to SC to fix
