The "ESC off" light is constantly illuminated on the dash, and my mechanic could not turn it off. Sometimes, after emerging from a 90-degree turn (I.e., at an intersection), the car's brakes will suddenly engage on their own (and usually "pump"), rendering the accelerator inoperable and the brakes uncontrollable, while the "ESC off" light flashes on and off. This has lasted for as long as ten seconds, causing the vehicle to slow almost to a stop in traffic. I have searched online and found that I am not the only Kia owner to experience this.

I was pulling into driveway when I started to back up to straighten myself up so that I could pull straight up into the driveway. And when I took my foot off the pedal, the pedal was stuck causing me to accelerate at about 60mph. My car went over a tree stump resulting in me crashing into the neighbors house. While this was happening, the brakes would not properly work.

Husband driving, car stopped suddenly, he hit brakes, brakes failed, and rear ended car in front, who then hit car in front, who then hit car in front. 1 or 2 people injured and was taken to hospital. We are sore, but will survive. Was recall on part that was replaced, faulty brake light switch. Switch was replaced in Sept. 2013 and accident was 11-12-13. Had mechanic checked and codes C1513 and C1616 came up. Have been told this could have caused brake failure. Concerned that a part that was replaced one month before accident, had failed again. People will be injured or worse killed because of this problem. Been speaking to man in Canada via internet, who has exact same vehicle, same year, same make, who also had brake failure. Spoke with Kia, they refuse to do anything. Please do something about this before others are injured.
