Jeep India — mileage of newly purchased jeep compass

Address:

560035

I had raised the issue with my newly purchased jeep compass (Petrol - sports) on may 20, 2018 with the jeep showroom but haven’t received a response yet!
The issue was with the mileage of the vehicle. The arai claimed mileage is 16 to 17 kmpl whereas the actual mileage of the vehicle is only 5.7 to 5.8 kmpl. Each time i talk to the sales person at the showroom they have the same response that the mileage with drastically increase after 500 to 1000 kms. Such a drastic increase in the mileage is not possible and not practical and does not seem like an appropriate response. I seriously fear that the company has sold me a faulty vehicle and demand a replacement or refund for the vehicle.
I’ve also communicated the above to the sales person at the kht prime showroom in domlur.
