Hyundai Motor India — poor material built in quality

Address:

Kottayam, Kerala

Dear sir i have buyed an hyundai creta on 2015 spending about 11 lakhs rupees now its silencers leaking and noice of the car has been increasing. I have welded it 4 times and then also same problem repeates is this is the quality of 11 lakhs premium luxury car? This shows poor building quality of the car, poor material selection and very poor r&d department.
I need to a full replacement of part
