Renault Kwid .....

In October 2017 ,I purchased a brand new renualt kwid, Two months after my purchase the brakes ... were worn out , and To my surprise when I took it in to my local Renault dealer they told me , that the service plan does not cover the replacement of the brakes... So I had to pay for them .. SHOCKED... Then 6 months later the battary started to give me problems , When I took it for its service I specified that they need to check the battary but nobody even bothered to do that and the told me everything was 100% ... Since then I have been struggling with the battary , so I finally saved money and bought a new battary ...,, AGAIN TO MY SURPRISE 2 days after I purchased the battary its flat ... I WOULD JUST LIKE TO FIND OUT ..... Why is there such a problem with these cars ... reading all the reviews .... I TOTALLY WASTED MY MONEY .... This car is one problem after the next ... The poor quality of everything ... From the door nobs , to storage compartments .... everything is broken ?
