Optima Hybrid 4-cyl

When applying gas pedal to pull away from a dead stop--such as a stop sign or red light---car stumbles and hesitates. At times car will not even respond when gas pedal is pushed. Push the gas pedal and nothing happens--then you push pedal a bit more and it jerks and shoots forward. Not a comfortable situation when trying to pull into traffic from a intersection. Happens virtually every time. Cold or warmed up--same problem--except a lot worse at cold start. Once above 30 mpg things smooth out--but the big danger is trying to pull out into traffic. I have been to the dealer several times. They do a re-flash or whatever--then tell me it drives normal. No fault with the dealer at all--they have been excellent really--but--can't fix the hesitation.but driving normal--that's not true. They know they have a problem with this hybrid system--there is a web page that addresses this problem---everyone has the same problem. I can't even allow a friend or one of my kids drive this car.if you don't know how the cars going to react---your open to a serious accident. I have had a Camry hybrid and two prius hybrids--no problems. I know how a hybrid car should drive. This car is unsafe for the driver and other mortorists on the road.
