worst brand ever

I am driver of a new qashqai, on the last Thursday of March 2016, at 8 hoo I got stuck on the highway as the car could not allow any of the gears to operate, I was assisted at around 14h00, after a principal dealer from Hatfield intervene, to cut matters short car was sent to northwest, of which h they came back with the feedback after five days, the diagnosis was that the clutch h is damaged, now my problem is that nissan is not prepared to take responsibility for this, this car is under warranty, secondly I have driven a GM of which I bought way cheaper than this for five years, Never had to replace any clutch so early, I see there is quite a few of complaints of this nature about the same qashqai, I m prepared even to go the radioENCA to find out as many people as possible who have been sold shoddy cars by Nissan,I bought an expensive car with the hope of longer duration, I need my car placed back all the parts taken out to Hatfield, will send lawyers if I have to find out how many people have been taken for a rider, there is even a Complainant whose Qashqai failed after 15 000 KM WHAT is that. I drove an I 20 hands, Never experienced such bad quality, nissan get my car
