TVS — jupiter standard bs iv vehicle replacement issue

Address:

pune, 412101

Hello team,

I have purchased a new jupiter standard bsiv from tvs - sai baba sales pvt. Ltd. Chinchwad on last week.
After booking as per traffic rules i have kept there for 3 days for passing on thursday evening i brought vehicle at home.
Saturday 24th january 2020 morning i have observed vehicle cvt assembly having multiple cracks the same attached snapshot for your reference.
It's not an individual part its coupled with engine if the plan for replacing that part so the engine needs to open for new bike engine opening not accepted for me.
I have reported to tvs as well dealer and asked for vehicle replacement, after multiple followups i got a reply from tvs as a vehicle passing completed so we can't replace.
Is there any amendment in our transport traffic rules once unfit vehicle registered in the system it's not replaced with new one?
If having such criteria please request you to keep some obligations for a new vehicles.
It's one of the tvs quality control issues and how can tvs pass such material under quality test control?
How tvs can play with customer life by fitting such a damaged product.
