Unreliable and Faulty Nexon

Purchased Nexon XZA+ on 20/6/2019 from Ambattur, Chennai. High vibration of car in 1st gear and reverse from day 1. Dealer executive said " I have to get adjusted to new Car" !!!!. Weird noises after applying brake from front and back. Complained at Service center - they said it is normal. Complained to CEO Concorde and Tata Motors twice no use. They will call and say everything is normal. Complained to Customer care head - Vehicle was in service center for 7 days (in 2nd month of purchase, earlier visited service center twice within a month) and found that Clutch is defective. To change clutch and fly wheel they made to buy AMC Gold which I was not interested but to get my car out of service center, I had to pay. Nexon is Nuxan - never ending problems. As per TATA all these problems are normal !! 1. Knocking sound from engine while AMT shifts gear from 1 to 2 to 3. 2. Weird noises after braking. 3. Swing motion front & back like wooden toy horse after braking (min. 3 times). Even in Govt. you will not fall front unless hard braking. 4. Inconsistent and mis fits in interiror plastic - looks super rich from outside but plastic is of cheap quality - any item placed in glove box, door panel, sun glass folder will result in sound / vibration while driving. And lastly forget about mileage - 6 to 6.5 in city traffic while MID shows constant 8 which is tampered by TATA. Two months of nightmare owning this vehicle and feeling as if I have burnt my Rs.11+ lakhs. Reason for buying AMT is drive smoothly in traffic but Nexon is complete package of unpleasant driving experience in traffic. I feel as if I am driving a 10 years old car and sense that I may need to change clutch every 5000 kms. Everyday I have to be cautious that no other problem creeps in. Earlier I have driven Polo for 75k kms without changing clutch. When product itself is defective any level of service given by TATA will not give trust on their cars.
