Bumy Ride on new honda city 2017. Poor suspensions.

I purchased honda city 2017 petrol V model as my second sedan . I was very enthusiastic as this is premium car in its segment & mainly that great name of HONDA. But after using the car for about 2000 km, i wonder about my decision. It had great looks with spacious seating & reasonably good interiors & electronic controls. Its pick up is average or sluggish. Needs higher throttle. Gear change is not smooth especially 1st & 2nd & creates khut noise . In bumper to bumper traffic needs acceleration orherwise it is jerky or stops. Worst aspect of the car is highly continuous jerky & bumpy ride at rear. Its so harsh that one feels seating in auto or scooter. The jerks dont stop. Its painful & one may have to go to orthopaedic doctor for bodyache. Dealer is clueless & my frequent visits including sending video of ride to Honda helpline is yielding results. Feeling like getting back my old fiesta or selling this new car . Recommend not to buy this car.
