Tata Motors — Defective vehicle delivered

Address:

Villupuram Schakralaya Motors

Dear Sir/Madam,

I own Tata Nexon XZA+ Diesel 2021 model.
Only 6 months since I purchased the vehicle. I received the vehicle from Schakralaya Motors Neyveli.
I am facing repeated DPF clogging and check engine lamp issue for the past 4 months.
Today is the fifth time this issue has come and it's been only 2 days since I took the vehicle from the service centre for the same complaint(20 days at service centre).I doubt if I have been delivered a defective vehicle for me.
I need my issue to be resolved permanently or else i need a replacement PETROL vehicle if there is no permanent solution for this problem.

Thank you
