Nexon XZA DT diesel

I have purchased Nexon XZA DT diesel But after purchasing within one month AC was not working. Claimed warranty and repaired without any additional cost. At the time of delivery steering was tight while Ac repairing time I complained about the tight steering. Now both the problems have solved. In eco mode car pick up or acceleration is very less.. am getting millage 17kmpl with Ac, in Ghat section auto mode worked very well.
