Unhappy Nissan Customer

I recently bought a Nissan Magnite and I must say I am impressed with the performance Sadly what Nissan makes up in performance sorely lacks in the quality of materials used on the vehicle and the after sales service. 1) Within a few months I had the right wiper blade fail. It was replaced and failed again after a few months 2) The door locking levers rattle 3) The Black Plastic on the Rear View Mirror just cracked, (Nissan replaces this with a mirror that now has a Renault badge on it. Not sure what is going to do to the value of my vehicle. 4) The black front side trimming along the windscreen is faded (seem like the black plastic is made of poor-quality material hence the rear view mirror cracked and the trimming are fading). 5) The brake makes a squeaking noise every time you brake, took it in for cleaning, one week later it started again. Was told it’s the powder from the brakes discs. Just poor quality discs I would say. 6) The auto locking function just stopped working. Sadly Nissan SA seems to have no interest in looking into the problems. This is going on for months. The request to speak to a manager at Nissan SA falls on deaf ears.
