Transmission acts weird, Lags power after coasting, or moving from one lane to another trying to pass, kicks and slips,at low speeds between 1, 2nd and 3rd, it is not a smooth sifting for a luxury sport sedan, RPM's goes high when braking (similar as braking with the engine), car still on warranty, but Dealer kept the car for a week, and say there are no faulty codes on the transmission, and Infiniti will not authorize a repair or transmission replacement, basically can not do anything to fix the problem, just reprogram it and that did not fix the problem, the issue is getting worst as the car is driven everyday, hope the car just quit and break down in the middle of the road...
