On 9/19/2012 at 12:17 pm I took a frantic call from my wife. She had just stopped to fill up with gas, got back on the interstate and set the cruise control at around 75 mph. Shortly afterwards the front end started shaking and the vehicle started to lose speed. She shut off the cruise and was looking for a place to pull over when the vehicle started to accelerate on its own. It was already going over 80 mph when she called. I told her to stand on the brakes-no effect. I told her to put her foot on the brake and to push and hold the start button for 10 seconds-nothing (that is the override to get the car started when the brake switch malfunctions-we had just had it replaced at the dealership 2 weeks prior). I told her to shift it into neutral-the shifter is locked in drive. I told her to shift to a lower gear-it won't move. After 4 minutes the car was going over 85 mph-I told her to hang up & call 911 as she could tell them where she was much better than I could. A few minutes later I received a call from the highway patrol-they had 2 cruisers on the interstate with her trying to clear traffic ahead of her. I asked if they could get a cruiser ahead of her and let her nose up behind it and then use the cruiser to stop her. Evidently they didn't like that idea or it is against policy because they never did try that. The dispatcher had to hang up to concentrate on the situation at hand. I now had the dispatcher's number so I could call her back. At one point I called back and suggested that she engage the cruise control and try to slow the car with it. My wife does not remember ever trying this. This went on for about 45 minutes at speeds up to 119 mph. At the end one of the officers told her to put her left foot on the brake and pull up on the accelerator with her right foot at the same time. She went from over 100 mph to under 50 mph instantly, let go of the pedals.

Was driving along at about 35mph and noticed a vehicle turning in front of me. I brake to stop or slow down at least. The brakes failed completely, no brakes, did not stop vehicle. It was like the anti-lock system was trying to work, but worked faulty, almost in a reverse fashion. I pressed brake pedal to no avail, like it was slipping, but nothing to slip on. Long story short I ended up going in the ditch to avoid running into the vehicle. Previous to this about 2months the shifter would not go into the park position, no matter what I tried, thankfully I was near the dealership. They replaced the brake controller and it seemed to fix the problem until now. Furthermore, when I go around a corner at a reasonable speed the engine kills power for a split second, and the anti-sway lights kick on. This seems to be more of a safety concern than a safety fix. I feel having 3 serious potentially life threatening situations in the last 3 months merits further investigation into this model of Kia, before it literally is killed in action, Kia. I recently watch the news and saw a stuck accelerator problem on this model as well, hope you will take action.

My husband was on private property. He got in the car, put the car in reverse and backed up. He heard a loud pop. He put the car in drive, and his foot was still on the brake. The car began to accelerate on its own with his foot on the brake until the vehicle got up to 60 miles per hour. Trying not to hit the house, or the person outside of the property he maneuvered the car into the back yard. The car was steadily picking up speed and his foot was on the brake the entire time. He could not get the gear to shift or the brakes to work. The vehicle struck a tree and that impeded the movement of the vehicle. He turned the car off and got out of it.

Stability control and downhill assist lights illuminate while driving. Then when stopped, car will not go past neutral when trying to shift into park. Also, when driving, the brake lights do not work immediately when pedal is depressed. Car will not shift out of park after started and stability control and downhill assist lights are illuminated. Located switch at the upper part of the brake pedal and while car was in neutral, with parking brake on, was able to bump the switch box and then shift car into park.

Vehicle unable to start, even with key in 'holster' in glove box. Vehicle brake appeared to be pressed down already and no reaction when start button was pushed. This happened multiple times over a 3 day period. After multiple attempts over two days, the vehicle started. Taken to dealership who detected nothing and were unable to duplicate the situation.

The contact owns a 2011 Kia Sorento. The contact was traveling 35 mph when the brake warning light illuminated. The contact then proceeded to depress the brakes but the vehicle failed to stop properly. The vehicle was taken to the dealer where the dealer confirmed that the master cylinder needed to be replaced. The manufacturer was contacted but the vehicle was not repaired. The failure and current mileages were 15,235.
