Horrible product in this range

I purchased my Kwid car in 2016 27 June, 5 years running , and now its 48200 km. I drive my car always on highway, city, rural and occasionally going to hill areas. its a best car. Driving quality is nice. Performance is good. Looks so beautiful. I just loved it. I personally believe that Guwahati TI Renault always provides very good excellent service to the customers and maintenance cost is almost nothing. Yearly 3500 to 5500 rupees. But I have to face one small problem is silencer which has a bad sound. I hope company will solve these problem as soon as possible and another problem is accelerator pedal which I changed 3 times, two times company free and last one paid .
