My maruti dezzire car which was purchased from m/s anand motors, chinhat branch, lucknow on 28 january 2018 was running smoothly but on 3rd august, car was parked on road outside the house. At night, when i opened the door, i saw that below the driving seat, some water was present. I suppose that there were some leakage inside the car, but after seeing inside i saw that the entire inner floor of the car was flooded with water
I could not understand the reason even after 6 days passed, even entire inner floor is wet. Kindly understand my problem and resolve it as soon as possible.
First free service of my car was on 24 february 2018
