While driving (in forward motion), without any pressure being applied to either the brake or parking brake, the vehicle begins to slow itself rapidly losing acceleration. ; a rumble can be heard there is consistent beeping noise and the vehicle begins to vibrate slightly. A yellow triangle with an exclamation point and the words check brakeappears in the drivers display; attempts to accelerate increases the rpms but the vehicle continues to slow rapidly. Not idle as if it were not in gear, but just as if the driver was breaking suddenly. The only known method of correcting this is to turn the vehicle off and restart it. However, this stops working as a solution after a few days and the problem persists. When the vehicle restarts you can feel the brake pedal release. This has occurred randomly at least 20 times in the past before until eventually it could not be driven at all. At speeds ranging from 25 mph on neighborhood streets to 70 mph on busy freeways. I sincerely fear that if not corrected it will lead to a (potentially fatal) vehicle collision. I also took the vehicle to a near-by kia dealer service department in CA. After months the car was returned and it continued ot have the same issue within a days. They were unable to diagnose or duplicate the malfunction as also. I have video of this as well. This needs to immediately be corrected and the technicians need to know what the problem is and how to fix it rather than experimenting on owners vehicles for months or weeks to then return it without resolution. Why should I or any other kia owner bear the burden of these unnecessary costs, inconvenience, and extremely unsafe conditions. Kia needs to respond I am sure others have experienced this same issue and should come forward immediately for the safety and well being of all.

Takata recall- when braking pr pumping the brakes there is a knocking noise, this also happens when releasing the brake pedal on flat roads or hills. There is a creaking noise when releasing the brake after putting car from park to drive or reverse.

While driving (in forward motion), without any pressure being applied to either the break or parking break, the vehicle begins to slow itself rapidly; an audible rumble can be heard and the vehicle begins to vibrate slightly; a yellow triangle with an exclamation point and the words ¿check break¿ appears in the driver¿s digital display; attempts to accelerate increases the rpms but the vehicle continues to slow rapidly - not idle as if it were not in gear, but just as if the driver was breaking suddenly. The only known method of correcting this is to turn the vehicle off and restart it. When the vehicle restarts you can feel the brake pedal release. This has occurred randomly at least ten times in the past two months, at speeds ranging from 25 mph on neighborhood streets to 70 mph on busy freeways. I sincerely fear that if not corrected it will lead to a (potentially fatal) vehicle collision. I took the vehicle to a near-by kia dealer service department on 21 July 2016 but they were unable to diagnose or duplicate the malfunction.

Originally the noise started about a week ago I took it to the dealer they did verify my complaint and they fixed it then on 2/14/2015 started to do the same thing the repair invoice states they performed brake fluid bleeding and calibration of the brake system.

Kia Optima Hybrid system warning no brakes! unsafe car! we have the same problem as someone else on this site. Oct 16th 2014 we were pulling out of our driveway and received a warning on the display saying "hybrid system warning slow down and come to a stop. Check brakes. Also the brake pedal had depressed all the way to the floor and there was a grinding sound. Unlike a low pad sound but the sound of gears not engaging. Also there were no brakes at all, the car wouldn't stop. We turned the car off and then on again and it was the same error message and same pedal situation. So we left the car where it was. After a few hours we tried to start the car again, but this time it was fine, no error message, brakes worked again. So we took it to our kia dealer ship here in honolulu. After a diagnostic we received a report a few hours later. The report said that the car checked out fine and there were no error codes stored. The service advisor said this is an intermittent problem that they could not duplicate. We took the car home and did nt feel safe driving it as we thought what if this happens again. We then brought the car back to kia and told them how we felt. They said they did multiple test and after one week of testing could not duplicate the problem. The service manager was very angry with us saying we need to pick up our car and return the loaner. After I hung up I did my own research on the internet and found this identical symptoms on another complaint here but this person had got into an accident. I forwarded this link to kia, now they are so nice to us because I think they now see the danger. But they still have our car and can't figure out what is wrong. We are very fearful that this car is dangerous and will not put our kids at risk in this kia with no brakes! be warned this car has brake problems and one person has already crashed!.

Upon acceleration from stop or low speed, brake warning message displayed instructing me to safely pull over and stop the vehicle. Additionally, essentially all warning lights displayed on the information screen. Warning lights began flashing and door locks began clicking on/off. Car became disabled after a short distance and car would not move forward when in drive. Required tow to dealer for service. Dealer scanned the vehicle and found over 20 history codes pointing towards a can issue. After vehicle was serviced and road tested, history codes were cleared by dealer on 5/24/2014. Same problem repeated under similar conditions on 5/28/2014 and again on 6/4/204. During the third incident, the car became disabled immediately after entering an intersection at low speed and could not be moved out of the intersection under its own power, creating a safety hazard with cross traffic waiting to enter the intersection. After the second occurrence, dealer service department was unable to diagnose the problem or repeat the conditions. After the third occurrence, the car became operable a short time after the incident after turning the car off and on again a few times. After each occurrence, the passenger air bag warning light remained in the history code. Currently awaiting response and diagnosis of problem by kia district parts service manager.

To whom it concerns, I have a great safety concern related to the optima 2013 hybrid braking system. I am not sure if the behavior I am going to describe is typical or defective. When traveling at speed, with the cruise set, I find that any sudden and hard hit to the brakes will activate some type of automatic braking system. The braking system feels like abs and sounds very mechanical however the braking system does not deactivate after I remove my foot from the brake. The system continues to automatically reduces the car to a nearly complete stop (less than 15mph) without me having my foot on the brake. This has occurred multiple times, the most recent was 4/10/14. Earlier today I was traveling 50 mph on the highway, with the cruise set, when it appeared a person was going to walk into the highway. I hit the brakes hard to avoid the pedestrian, who eventually did not enter the road. The situation was not worthy of coming to a complete stop however the automatic braking system I described above activated. I removed my foot from the brake but the braking system continued to bring the car to a speed less than 15 mph. The vehicles behind me, understandably, had to slam on their brakes to avoid me as I could not speed back up until the system resumed to normal operation. Please let me know if this is typical operation or a potential defect. I feel this could be life threatening. Should I have to hit my brakes and this system activates, I could be severely rear-ended. Thank you.
