NHTSA Complaint #11039679 — 2011 KIA OPTIMA

BEGINNING IN SPRING 2017 MY 2011 KIA OPTIMA EX TURBO (I BOUGHT IT BRAND NEW, ONLY OWNER) BEGAN STUTTERING WHILE IN MOTION (AS IF SOMEONE WERE PUMPING THE BRAKES). THE CAR STALLS AND DIES AT RED LIGHTS AND STOP SIGNS AND NEEDS RESTARTED. IT ALSO STALLS AND DIES WHILE IN MOTION, MOST DISTURBING IN HIGH SPEED, HIGH TRAFFIC INTERSECTIONS AND AT 70 MPH HIGHWAY SPEEDS. I WILL BE TRAVELING ON HIGH SPEED INTERSTATES AND THE CAR JUST DIES AND I HAVE TO HOPE I HAVE ENOUGH MOMENTUM TO SAFELY GET OVER TO THE BREAKDOWN LANE WITHOUT CAUSING AN ACCIDENT. THE CHECK ENGINE LIGHT USUALLY GOES ON AND OFF AT LEAST FOUR TIMES IN BETWEEN EACH SERVICE ATTEMPT. IT HAS BEEN ANALYZED AND GIVEN ATTEMPTED REPAIRS BY A KIA DEALERSHIP FOUR TIMES SINCE LATE MAY 2017 (SEE ATTACHED RECORDS), BUT THE STALLING AND STUTTERING PROBLEMS PERSIST. I PICKED UP THE CAR FROM ITS LAST SERVICE ON 10/18/17 AND THE SAME PROBLEMS BEGAN MANIFESTING AGAIN. THIS IS NOW THE FIFTH TIME. I HAVE NO IDEA WHAT THE PROBLEM WITH THE CAR IS (UNKNOWN) AND IT SEEMS KIA'S SERVICE HELP LINE FOR MECHANIC ASSISTANCE DOES NOT EITHER. THE MOST RECENT TIME THE CAR WAS AT THE DEALERSHIP FOR SERVICE, KIA SENT OUT A NATIONAL SERVICE SPECIALIST TO INVESTIGATE THE CAR, TO NO AVAIL. 1) 5/31/17 - REPLACED MAP SENSOR (I PAID $600 AND IT DID NOT FIX THE PROBLEM) 2) 6/30/17 - TESTED GROUNDS AND REPLACED CONNECTIONS 3) 7/25/17 - REPLACED TURBO AND INTERCOOLER SYSTEM 4) 10/12/17 - REPLACED ENGINE COMPUTER 5) UNKNOWN - STILL PROBLEMATIC - ASKING FOR REPLACEMENT VEHICLE FROM KIA THE CAR HAS 91,410 MILES AND IS STILL COVERED UNDER THE 10 YEAR/100,000 MILE POWERTRAIN WARRANTY. THIS CAR IS A MAJOR SAFETY HAZARD, ESPECIALLY WHEN IT STALLS AND DIES OUT IN HIGH SPEED, HIGH TRAFFIC INTERSECTIONS AND ON FREEWAYS WHILE TRAVELING 70 MPH. KIA OBVIOUSLY DOES NOT KNOW HOW TO FIX IT.
