Brake Light On problems of the 2013 Kia Motor Optima

While driving on the interstate the car began to lose power even though I had my foot on the gas pedal. Once home, after turning the car off I noticed that the brake lights were still on. Driving the next morning we paid attention to the brake light in the rear window and every time the car would start to slow down or seem to lose power the brake light was on. It is almost as if the brakes are engaging on their own. You could see the light flickering but if you hold your foot under the pedal to keep it from moving there was no issue.

Brake lights will not go off after I turn off my car. Sometimes the brake lights and back lights pops on even when the car is off and will not turn off. The slippery when wet light stays on at all times. When I am driving the car and I have to use the brakes to stop at a red light or stop sign the car moves very slowing and stalls. Sometimes when I am driving the car looses power. I was driving on the interstate twice and the car just lost power and began to slow down. This was a huge safety concern. Now the car has no power.

The anti-lock braking system failed on this car. If you would hit a bump in the road while acceleration the car would detect a spinning condition and cause major deceleration being very dangerous when entering a freeway in moderate traffic taking the vehicle from 60+ mph to virtually 40 mph with no warning and no brake lighting to warn approaching traffic. After many visits to kia dealer remained unaddressed until contacting corporate kia and finding a posting on kia Optima forum with another user that had same issue and was finally resolved with some hydraulic part replacement that costs $1,600 and was being avoided by dealers. When I brought this to kia corporates attention they agreed to replace with that part which did almost resolve that issue except on rare instances car will still hesitate when encountering a bump on acceleration. After that repair however the anti-lock brakes are now failing with erratic pulsing on hard braking and less effective braking.
