Honda — complaint about my dashboard sound while on top gear and back brake sound persisting after complaint reported at service center 5 times

Muthoot honda,Kollam ,kerala

Sir,
Myself dr vaisak vijayan a proud owner of honda city in kollam city, kerala. My vehicle register number is kl 02 av 5299. I did all the periodic service of my car at muthoot honda service, kollam from where i bought the car. My car ran nearly 55, 000 km till now. The problems started after 40000kms. First it was extreme vibration at the dash board on top gear... For this complaint i went to service center many times and their excuse was flywheel stuck in cletch and we need to change it. Itvran only 50000km that time and i asked for the reason and their reply was honda cars will get cletch issues often. And cletch is not coming under warranty so if i need to get complete remedy i need to change cletch. So i was not in state to change it so i didn change it.
Now the next complaint started after the 50000km service. It is a sound from the back while applying brake. I reached the service center and informed them and the reply was while service some dust may have entered the brake and will rectify it for that i need to give the car for 1 day. Each time mr erwin was the advisor.
I went there and gave the carfor 1 day and they gave the car and said it's finished.. But on ride the same issue persisted and i revisited the service center 4 times. Each time they will keep the car for 2 days and will give saying all work done. But it persisted. So i revisited them 3 days back and the service manager came to me and said to give the car for 3 more days and they will contact honda for the same and will do the needful as they can't rectify the complaint.
Today i called them again and they telling that as per honda they are doing the job and honda is telling 2015 model cars have this issue which can't rectify.
So i need a clarification on this matter. Does honda cars have defect which honda can't rectify, if yes then i think honda is not eligible to claim their pros in advertisements.
I need a solution on this matter as i bought your vehicle on the trust i have with honda brand if you are not capable of rectifying a complaint even after 5 times of reviews at their service center and passing comments of this issue is common with honda cars by service personnel's then you should have a rethinking whether your staff are eligible for this job or not.
