Zeiss Batis 18 heavy startup motor noise

Got the lens new from B&H and used for just one week. It was silent, but now aperture motor starts to make noise at startup or shutdown. I noticed that the sound is from the aperture motor adjusting to open up/close the aperture to protect CMOS. Sometimes the noise is so noticeable the camera shakes a bit.

Oh, the noise gets better overnight after a day of heavy use. Does this sounds normal? I only know that a car motor needs tuning when it makes noises
