I first noticed a problem with my vehicle when the cruise control would randomly disengage while going down the interstate. Then a couple of weeks later I was making a left turn across a two lanes of traffic on a city street. When I first pushed the accelerator the car started to go and then suddenly I lost all acceleration. I let my foot off the accelerator and then pushed back down and was able to go. This was a very dangerous situation as I was stuck in the middle of two lanes of traffic for several extra seconds longer than necessary. A similar situation happened a couple of more time and when I parked the vehicle at home I noticed that brake light was staying on after I got out of the car. I took the car to the local Kia dealership and they replaced the brake sensor which fixed all of the above problems. I would like to not that Hyundai issued a recall on the nearly identical sonata for this same issue and did so years ago and yet nothing for the Optima.

My Kia Optima ABS system will randomly make a crunch sound when I step on the brakes, and I lose some engine power immediately after to the point that my car will not accelerate past 40 mph. It has happened several times on busy highways where I have to fear causing a major accident. Kia dealer cannot figure out the issue, they had my car for a day and repaired the steering column and sent me home, only for the problem to occur again the following week.

On April 5th 2017, my Kia Optima started to make a horrible sound. I was on hwy 26 headed into portland or. Going through the tunnel, as I was going into the tunnel the horrible knocking noise started. There was cars in front of me and cars behind me. This was at 4:30 am.. all the lights on the dash came on, I had no brakes, no steering and no way to accelerate. Drifted to the side and had it towed.

I have a 2012 Kia Optima hybrid of which I purchased at the local Kia dealer (Ontario, ca) and even purchased an additional "platinum 100K mile protection." On December 31st my car started to move while in park and the ignition on. I hit the breaks and there was no break pressure at all. The car started to flash codes regarding the brakes and I had to engage the emergency break to stop the vehicle. The dealer could not find the issue and returned the car. Another month later the car did the same thing and I video taped it. The gauges started illuminating and delluminating repeatedly and all the lights on the dash started to flash. The "check brake" code came up again! I now have proof of the vehicle doing this and brought my car back to the dealer now they have admitted something is wrong but they're still unable to duplicate the error. They are keeping the car for further diagnosis but have not done anything but tell me they do not know what is wrong with it yet and that my warranty "may not" cover it. They have told me repeatedly that they will not be able to fix it or do anything for me until they know what is wrong, nor have they offered me a rental car. I want my car back but it is unsafe! what if the brakes go out at a high rate of speed?! please help me NHTSA so we can save lives of others that may experience this problem as well.
