I was traveling on city street at 35 miles per hour when engine has stalled suddenly, without any warning. I lost power steering and barely made it to the side of the road moving by inertia. I was very lucky there was no car behind me and I was able to stop safely. If there would be other traffic situation, such problem with the car could possibly result in fatal accident. The car was towed to grossinger Kia dealer in lincolnwood,

When traveling above 25 mph, when I take my foot off the gas pedal in anticipation of an upcoming red traffic signal or on the highway doing 55 or so and seeing traffic coming to a halt ahead, foot off the gas pedal engine keeps going, will not throttle down to near idle.,its as if the gas pedal is stuck. At this point I have to really brake hard to slow the car down, it is dangerous, especially at highway speeds..eventually as the car slows to a crawl the tachometer eventually shows the engine is down to idle speed., and the engine stops pulling on its own..my other issue involves the transmission downshifting to a lower gear and slowing the car down, I have no issues when accelerating, only when I tale my foot off of the accelerator, my Kia dealer cannot duplicate problem even after several visits..I have made a short video of the speedometer and tachometer, and it clearly shows the the car going on its own, while my foot is off the gas pedal.

When accelerating from a stop, if done in a start, stop, restart fashion, it does not immediately re-accelerate. This condition can occur when stopping prior to pulling out into traffic.

On Saturday - November 22, 2014 around 6:30 pm the car engine stopped and car rolled for few feet and stopped in the middle of the street. Also steering jammed and didn't move. It was stopped and didn't start back on and steering became very hard to crank it. The battery was running fine. Due to electrical and/or mechanical failure we were exposed to the unsafe environment. Fortunately, we were not on the busy street/freeway otherwise it could have been ended up in major safety incident. When this happened, we couldn't maneuver the steering resulting in situation totally out of control.
