Hyundai Motor India — I am complaining regarding the unresolved defect of my car grand I 10

Address:

Kamrup Metropolitan, Assam, 781024

Sir /madam
i am a customer of hyundai possessing grand i10 era . i had purchased in the year 2014 from Mukesh hyundai, guwahati, Assam .After few days from the purchasing day i heard a crackling sound from the left rear side somewhere from the wheel area. i immediately visited the showroom and enquired. but they told me it was a minor problem and can be solved by just visiting a service centre. I went to mukesh hyundai service centre at LAST GATE, Guwahati. I am not sure but approximately i visited 10 times to the service centre . you can verify it by the records and documents maintained by the service centre. At last they found it the problem was in shock absorber and they replaced with a new one as per them . It took around two years to get rectified .They closed the complaint after that. But now from 2018 november the same problem again started and now the sound is quite audible.
Now my question is whether the car was a defective right from the manufacturing and without assessing by your expert team they had sold to me or if the problem was in shock absorber and which was being replaced was not a genuine part.
i already have Maruti Zen which had covered around 70000 km as compared to the grand i 10 which had covered merely 20000 km does not have any problem of shock absorber till date.
I am being a busy medical practitioner have already wasted lot of time in visiting service centre and i think if i will again visit i am going waste money and time both and that also is not sure your service engineer will be able to solve my problem.
This time i am going to put the matter on the consumer forum since i feel i have been cheated by selling a defective car and since warranty was there i have been given mere promises and passed the warranty time.
