It seens to be that the abs issue is with multiple cars, my cousin is also facing the same with his 2018 model v2.
For abs replacement visit any good mechanic who deals with japnese cars, they will have it with them should be around 25k now, if you want to save some money do visit bilal ganj type markets and get it yourself and then visit mechanic for fitting.
I wad based in Lahore at that time so got it from a mechanic on Lawrence road, behind those cylincer dealers, near ganga ram hospital, as per the mechanic the abs kit he fitted was from a Nissan Juke, but he said that he has fitted few from honda city in v2 as well previously, all working fine.
