Sensor problem

I bought this car on 01/05/25 On the second day of purchase, I noticed a request sensor problem. I visited thrice for the same problem at the dealership, but not been resolved yet. Another problem you must lock the rear seat belt even if no one on the seat, otherwise the seatbelt warning remains beeping. The request sensor must have body contact with the key. But in Tigor, you don't even need another person can open the tail gate despite the locked car. pls, Tata, improve this, it's not safe..
