i bought vxl variant in april, and during 1000km free service in the month of june, i complained that rear view mirror is faulty, i usually park my car under shade, but if i had to park under sun for some time, then rear view mirror rubbers got lose, and the mirror start making khar khar noise while driving, but after 5 minutes when AC cools the environment then the issue vanished. and no khar khar sound from rear view mirror.
i also have the video of this issue made on 12 November when the temperature was only 24 or 25 in Islamabad.
