I brought maruti ertiga zdi+ hybrid engine car on 1 september 2017. L from sehgal auto, baner. At the time time purchase sale person told me mileage is 19 in city and more than 22 on hoghway woth ac. But initially car was giving 11, so i asked the workshop person. He said it required some more time to tine engine. Then i drove car to chandrapur. But still on even highway i got only 15 kmpl. It’s really pathetic mileage bu maruti. I already told sehgal representative, but they haven’t called me back.

I think there is problem woth engine. I want replacement of engine. Hybrid car should gove me atlrast 18 or 19 in city. I use this car for daily commute. For a diesel car performance is pathetic.
I need justice from maruti.
