Filed Aug 21, 2023 · Brakes, Engine · MO · crash

I was turning into some parking spots so i could put my car in reverse and park closer to building i needed. I did not get a chance to putin reverse, the vehicle surged forward and was accelerating. My foot was not on the gas pedal. I was trying to brake. I turned steering wheel so I didn't hit brick building. I swiped the building and 2 vehiles on my right AND still did not stop right away. I kept on the brake and the plants, rocks, landscaping I think helped it to stop. I can get police report in few days.

The contact owned a 2013 Kia Optima. The contact stated while her son was driving approximately 35-40 MPH, the check engine warning light illuminated and was flashing; however, he continued driving the vehicle. The contact stated that she later took the vehicle to an independent mechanic, where it was diagnosed that the knock sensor and an unknown component needed to be replaced. The vehicle was repaired; however, 6 hours later while her son was driving 65 MPH, the vehicle stalled. The vehicle was unable to restart and was towed back to the independent mechanic.

The issue with the car first occurred in 2021 when the vehicle had 109,000 miles. I was driving on the interstate returning from visiting my family when the car began to behave erratically. It started to seize, stall, and accelerated on its own. All of the lights illuminated on the dashboard with the error message hybrid engine, air pull over immediately. This was a serious event because my life as well as others were impacted. The car had just enough power to make it off of the shoulder when it died completely and had to be towed to the nearest dealership. They recommended I have the hybrid battery replaced which I did. That did not correct the issue because less than a year later in 2022 I was once again returning home and the car begin to do the same thing. Stalls, seizes, accelerates on its own and the same lights, the same warning message, and completely loses power when you’re driving! It was again towed to a dealership and this time they recommended I have the spark plugs replaced. The spark plugs were replaced and the day that the car was repaired and picked up it had to then be towed back just a few miles down the road with the same strange behavior, and the same issues. Clearly the recommended repairs are not fixing the root cause problem. And now three times my life as well as other motorists’ lives have been put in danger! I am tired of paying for recommended repairs that are not fixing the root issue when there are several hundred other persons who have been experiencing similar dangerous issues like mine with their vehicles. Kia needs to do something about this!

2013 kia optima sx turbo. While driving approx. 65 MPH on a hwy, the vehicle suddenly decelerated hard enough to make me lunge forward toward the steering wheel. I saw multiple warning lights come on the dash and when the gas pedal was pressed the car would not accelerate at all. I was able to get the car pulled off to the side of the road where I turned the vehicle off. I pressed the kia's start button, and the car would not start. The lights on the dash would all come on and there was a very strong odor of burnt electrical wires coming from the engine compartment. I had the car towed back to the dealership where they are currently diagnosing the problem. This is a very dangerous safety issue. Scary, to say the least.

On 5/15/14 at approx. 0430am, while at a stop light, the vehicle experienced unintended acceleration. With my right foot on the brake pedal the car suddenly accelerated. Because my foot was on the brake pedal the car moved less than two feet. I then placed the automatic transmission into neutral, where the motor rev'd to approx. 7000 RPM. I then immediately turned the car off, and then back on. After turning it back on, the car then resumed normal functions. Later the same day I took the vehicle to my local kia dealership. According to the serviceman, a comprehensive analysis was performed, however they were unable to duplicate the issue.
