Renault Centurion

If i Could give 0 starts i would.... Brand new Kadjar bought from them in January 2018 So the first 15000km sevice came along and i was met by this rude and un approachable man called Andre asked to check specifically the rattle on cluster ....low and behold after receiving car it was not done .NO PROBLEM then came the 30000 service to be told someone used my service !!!!! so i had 2 wait another week before car went in ......on booking day car was booked in and again i asked about dash rattles ....i was told by ANDRE sorry after 10000km Renault charges for service...again i accepted the fact.....day goes by and at 15:00 in afternoon i was told that the car needs to come back for brakes ....i then started questioning their procedure as i know car get lifted and gone through and parts ordered. Ok after a few words he gets brakes authorized. now 3000km down the line my right front disc started forming a ridge or line in disc and Renault says its a caliper spring ......so i ask u is it bad installation or a freak of nature that a spring from the outer caliper grinds into disc .Apparently it still ok and wont cause any harm.... I have never ever had such a bad experience from a dealer or any Car Company
