The Driver Information System(DIS) of Indigo Manza does not display the correct mileage. I confirmed this from tata service station. What is your opinion about this? Moreover, the min mileage it displays is 10 and max 25. Then I often feel the car too bumpy in the khuds and feel vibrations in the steering. My service centre told that this is by default and Tatas technology is like this. I drive from Faridabad to Okhla everyday though the Surajkund road and this road is quite bumpy. It looks quite surprising the way car behaves over the khuds or bumpy roads. Does not look normal to me. You have to hold the steering very tight to keep the car in control.
