| Description of the problem | 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. |
