My 2010 Kia Sedona has a major problem with the brakes. I had a problem with the brake pedal sinking too far. I took it to a local mechanic. This mechanic installed a new master cylinder. Two days later the brakes started to grab. The brakes were activating without my foot on the brake pedal. I had the Kia towed back to the local mechanic. The local mechanic said the master cylinder was working properly. This mechanic told me to take it to the Kia Dealership to reprogram the ABS Module. I have had the Kia at the Kia Dealership three different times for this same problem. The first time the Kia Dealership did do some reprogramming. They also said there was rust in the master cylinder reservoir. The Kia Dealership has driven the car several miles. They claim they can not duplicate the problem. So they have given the car back to me without doing anything. I have had the problem with the brakes grabbing on three different occasions. Each time I have had to have the Kia towed. This problem with the brakes grabbing is extremely dangerous. I am barely able to pull off the road and get the Kia towed. The car will slow down considerably. The car will be hard to control. All four rims have been very hot each time when I touch them with my hand after pulling off the road. The left front rim had smoke coming off it the first time this happened. I have to put on my hazards lights as I can not keep up with traffic when the brakes grab. Also, the first time the brakes grabbed, the ABS and ESC warning lights came on. The last time the brakes grabbed the ESC Off light came on. The Kia Dealership has told me that there are no codes stored in the computer. I am afraid to drive the car. It is sitting in my driveway now. The Kia only has about 19,000 miles on it. I am trying to find a brake specialist locally that can inspect the vehicle brakes. Not sure what to do now.
