| Description of the problem | Shortly after test driving and buying a used 2011 kia optima lx, we began experiencing an intermittent engine hesitation problem when accelerating at low speeds. It may not occur for many miles of slow-and-go traffic but, when it happens, it is shocking because the engine feels like it is going to completely die for up to 3 or 4 seconds. This can be very dangerous while turning onto a busy highway or crossing a high speed intersection. I this hesitation problem will occur at random regardless of whether the engine or the weather is cold or warm. We left this car at a kia dealer for several days but they were unable to determine the cause of the engine hesitation problem. The engine has hesitated several times in the past month. |
