Automatic Emergency Braking problems of the 2013 Kia Motor Optima

Brake pedal loses pressure and disengages with brakes. Traction light, maintenance light, hybrid system warning message, check brakes message and parking brake intermittently turns on and off. I called kirby kia of ventura a few weeks ago and let them know about my issue with the car. I explained that I took the car to a mechanic and the diagnostic they did stated the issue with the car could be because of one of the recalls. On 4/10/26 I took my vehicle to kirby kia of ventura for the recalls and asked if they could do the diagnostic. Raul from kia was the service rep that spoke with me. He stated they would do the recalls and then, if needed, they would perform the diagnostic. Later that day raul called me and stated the recalls were completed and no issues were found. Several items were found from kia's point inspection, but none related to the issue at hand. I then asked raul if they could perform the diagnostic to know what was wrong with my car and he stated that they could do the diagnostic on Monday, 4/13/26. Raul stated he would give me a call around 10 to 11 am, to discuss any issues. Raul called at 10:49 am, and stated no lights on the dashboard have come on and he didn't want to do the diagnostic because the lights weren't on. Kirby kia of ventura service department are crooks and only want to assist you if they get money out of you. My car still has the same issue, possibly damage to the hecu from the recall, but kirby kia didn't want to run the diagnostic on my car to find out if it was damaged. Kirby kia of ventura is a horrible organization and I will never purchase another kia vehicle for this reason.

There is an hybrid warning coming on which causes the brakes to loose it’s ability to stop for some reason. It also slows the car to a hault while the engine is in full rev. It’s a huge safety issue as this occurs intermittently with no warning. Last time I was on the freeway, luckily I was able to pull over to the curb without incident. I hit the bumper a little bit but was able to stop safely.

The contact owns a 2013 kia Optima. The contact stated that while driving at an undisclosed speed, the vehicle was jerking and then lost motive power. Several unknown warning lights were illuminated. Additionally, the brake lights remained on while the vehicle was turned off. The vehicle also experienced phantom braking while driving. The vehicle was taken to an independent mechanic, who diagnosed that an unknown sensor needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 117,000.
