NHTSA Complaint #10855704 — 2011 KIA OPTIMA

SHORTLY AFTER TEST DRIVING AND BUYING A USED 2011 KIA OPTIMA LX, WE BEGAN EXPERIENCING AN INTERMITTENT ENGINE HESITATION PROBLEM WHEN ACCELERATING AT LOW SPEEDS. IT MAY NOT OCCUR FOR MANY MILES OF SLOW-AND-GO TRAFFIC BUT, WHEN IT HAPPENS, IT IS SHOCKING BECAUSE THE ENGINE FEELS LIKE IT IS GOING TO COMPLETELY DIE FOR UP TO 3 OR 4 SECONDS. THIS CAN BE VERY DANGEROUS WHILE TURNING ONTO A BUSY HIGHWAY OR CROSSING A HIGH SPEED INTERSECTION.I THIS HESITATION PROBLEM WILL OCCUR AT RANDOM REGARDLESS OF WHETHER THE ENGINE OR THE WEATHER IS COLD OR WARM. WE LEFT THIS CAR AT A KIA DEALER FOR SEVERAL DAYS BUT THEY WERE UNABLE TO DETERMINE THE CAUSE OF THE ENGINE HESITATION PROBLEM. THE ENGINE HAS HESITATED SEVERAL TIMES IN THE PAST MONTH.
