NHTSA Complaint #11252722 — 2012 KIA OPTIMA

MY 2012 KIA OPTIMA ON MULTIPLE OCCASIONS HAS SHUT OFF WHILE THE VEHICLE WAS IN MOTION. WHILE DRIVING, AS I DECREASE MY SPEED, SUDDENLY THE CAR WILL EXPERIENCE JERKING AND THEN SUDDENLY SHUT OFF. THIS HAS OCCUR WHILE DRIVING ON THE FREEWAY AND TRAFFIC HAS SLOWED DOWN TO 10 MPH OR LESS AND WHILE APPROACHING A LIGHT OR CROSSING AND INTERSECTION AND TRAFFIC IS SLOWING DOWN. WHILE THE CAR IS AT STEADY SPEED, AT 20 - 40 MPH THE CAR JERKS AS I'M TRYING TO MAINTAIN WITH THE FLOW OF TRAFFIC. MY CAR HAS HAD ROUTINE MAINTENANCE AND MECHANICS HAVE BEEN UNABLE TO IDENTIFY OR REMEDY THE ISSUE. MY LAST TWO INCIDENTS WERE 8/21/19 FREEWAY WHILE IN THE FAST LANE NEXT TO THE CARPOOL LANE AND NOW 8/29 ON CITY STREET. I ALSO EXPERIENCED THIS ON MARCH 3,2019 (HAD A FUEL PUMP REPLACEMENT WHICH STILL DID NOT REMEDY THE ISSUE)
