The forward collision system failed in my Kia 2019 optima. I was driving and the lights come on the forward collision lights and the engine turned off I had no control over the vehicle I couldn't even turn the wheel. It turned right on its own and threw me up on a bank and I rolled twice. The car was out of control. I've never been so terrified in my life. The safety measure failed and nearly cost my life. My brakes locked up as well and I'm lucky to be alive. This was uncontrollable the car was in control and it was wrong. I'm not sure if it was the forward Collison or the traction control and there were no warning lights ever on this was a new vehicle. I have witnesses that seen it someone pulled me out the vehicle bc my doors were locked. The car is currently deemed a total loss by state farm and is in Pulaski at IAA #5409946490. Stock # 31768854. …

It was snowing and an icy day Jan. 21 in Atlanta, Georgia. I was driving on Buford Spring Connector going southbound. I was on a bridge and it was completely white and icy. I saw there was a car stopped in front of me. I tried to put on my breaks and my car would not slow down. I was getting closer to the other vehicle still trying to break. I tried to use my electronic emergency brake and it did not engage. The car did not even try to break for me which it normally does if I moving faster than a stopped car in front of me. I rear ended the person in front of me. I just wanted to let someone know as the forward collision did not work in this case and the accident could have been avoided.

On October 11,2022 I was involved in a vehicle collision that resulted in damages to the front of my vehicle and the rear of another. My two children and I suffered injuries that we were not able to recover fully from. The driver of the other vehicle was uninsured and has not been accessible!
I was driving and tried to brake but my car did not stop and ended up hitting guardrail. A couple weeks later I was driving and there was nothing in front of me but the car abruptly stopped in the middle of road
To begin, there was a recall on the forward avoidance collision system. The fix was to have the system reset at the dealership. Almost like a system update. I had that done after multiple lights appeared on my dash. 5 months later, the lights would illuminate again periodically, but turn off after a few minutes of driving. Two months ago, the lights came on when I was traveling on our highway at about 45 MPH. There was no cars in front of me, nor any objects. The automatic brake applied itself as I was turning off of this major highway. I hit the gas to try to turn off of the highway after the brake was applied, and my car wouldn't accelerate. Since then, the light has stayed on every time I turn my car on, and for the remainder of the time I'm driving it. The brake has also self engaged itself twice since then. It's a huge safety risk as someone could hit me from behind. …
I like kids however I purchased a Kia used in 2021, I started to notice that all consumption was going out fast before oil changes was due. I still have this ongoing problem but they say there's no recall on these GDI motors however other people I see informs or experiencing the same issues. I now have to try to get an appointment with Kia for an oil change before it's time for the oil change and to do a oil consumption test and then hopefully the main factors or kia will replace this motor even though there's no warranty on the car. I might also have a issue with the front collision feature because I have been noticing in the past few weeks that this feature comes on even when there's no car in front of me it will start to break however it says that my car is not a part of a software upgrade so I got to ask them about that as well. …
