Automatic Transmision not sync with engine rpm. Therefore very high fuel consumption

Exterior Excellent exteriors, rear view side mirrors need to be smaller and prone to damage.

Interior (Features, Space & Comfort) Excellent but seat is a bit hard.

Engine Performance, Fuel Economy and Gearbox Big problem with automatic transmission. Taken to Concept Hyundai three times. They are not able to solve problem.Pl let me know reliable workshop which can solve the problem. I am a senior citizen having driven manual transmission cars for 40 yrs. Regret buying automatic transmission. Hyundai cannot do any thing and  the staff in the workshops have poor knowledge of automatic transmission.

Ride Quality & Handling Ride quality is poor due to mismatch with engine rpm and transmission. Suspension is stiff.

Final Words Having visited hyundai show room a no of times , do not know where to go Unless  I get a solution I will be forced to sell the car.

Areas of improvement After sales service team should be sound.
