6 Engine Cooling System problem

Failure Date: 01/24/2016

Travelling at approximately 30 mph (had just turned onto road)when engine seemed to accelerate on its own. Pressed brake pedal (hard) and did not slow car at all. Continued to press brake and also pumped but nothing slowed vehicle. Although saw truck well ahead of me stopped, I could do nothing to stop or even slow down. I wrecked into back of truck stopped ahead of me waiting to turn. Approx 8000. 00 damage to my car mostly due to truck having a sizable trailer hitch on back that busted through a lot of front end plastic, cooling system, etc and buckled hood. No injuries but if would have happened at higher speed it would have been tragic. Officer upon arrival also noticed thatbrakes seemed to fail and noted it on his police report. I have since found internet sources indicating that some 2011 kias had in fact has a tsnb issued for unintentional acceleration problems. I never received such a bulletin and have had numerous services performed at kia dealership. Also, have had brakes checked multiple times at dealer and delaer inspection never indicated any problems. I hav ealso found documentation online that says if you have an unintentional accelleration, pressing the brake hard is the first step to do, but once you let off the brake, you totally lose brake pressure. Who possible would know that ? this accident is totally the result of a system failure of the vehicle and I am asking for assistance in persuing my damages as a result of this failure.
