TOOK POSSESSION OF 2011 KIA SORRENTO ON 2-18-2010. SINCE THAT TIME THERE HAVE BEEN 14 INSTANCES WHEN THE CAR HESITATED ALMOST DYING OUT AND THEN SURGING FORWARD. AT ONE TIME IT DIED COMPLETELY OUT AND HAD TO BE RESTARTED WHILE BEING IN THE LANE OF ONCOMING TRAFFIC. TWICE IT HESITATED AND SURGED AHEAD 4 - 5 CONSECUTIVE TIMES BEFORE SETTLING DOWN, ONCE WHILE CROSSING OVER A 4 LANE HIGHWAY. IT HAS BEEN BACK TO THE KIA DEALERSHIP 3 TIMES AND THEY CANNOT DUPLICATE THE PROBLEM, SO THEY CLAIM WE DO NOT HAVE A PROBLEM. WE ARE VERY CONCERNED ABOUT THIS AND BELIEVE IT IS A SAFETY ISSUE AND MY WIFE WILL NOT DRIVE THE CAR UNTIL THIS IS RESOLVED. UPDATED 03/16/10 *BF *TR UPDATED IVOQ 07/16/10*JB
