Tata Motors — Tata Harrier

I bought a Tata Harrier XZA PLUS Orcus White in July 2020. This month, I noticed that bubble like imperfections had formed in the paint around all four door handles. About a week back, one of these imperfections on the left door burst peeling off the paint and exposing the metal underneath which was heavily rusted. In addition to this, the rubber beading around the sunroof and on both edges of the roof has started coming out. The car is not even a year old. Even 20 year old cars don't have such issues. What to do now??
