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.

ELECTRICAL SYSTEM

i was driving on the freeway at roughly 60-70mph when the car suddenly began decelerating and not responding when the acceleration was pressed. this has happened 3 times since i have been on the roads. kia is unable to find error codes or diagnose the issue even after providing them with video evidence.there have been multiple "computer glitches" but this has been the most severe.

ENGINE

while accelerating from a dead stop, the car hesitated and stopped until it appeared to shift from electric to gas power. i thought at the time that it may have been a freak thing but this hesitation has recurred a few times since then.

SEATS

front driver seat feels like it rotates/slides upper rt corner about 3 inches from the side. then lower lt side about the same 3 inches from side. 3 months fighting kia for what i think is a safety repair. still has not been resolved. i test drove another hybrid 5k less miles, that did not have the issue. the second issue is there is a dead zone that is random to reproduce for the dealer is tough. it occurs when stopped, highway speed, etc. where you press the petal and nothing happens for about 4 seconds. then you have full power by then it is too late. if you do not know this can occur it place you in a tough driving spot.
