NHTSA Complaint #10712912 — 2009 KIA OPTIMA

I HAVE THE SAME PROBLEM AS OTHER DESCRIBE HERE. I HAD THIS ISSUE IN 2011 WHEN SLOWING DOWN FROM 10 MILE SPEED (BELIEVE) . DEALER FIXED WITH PROGRAMMING (AS THEY SAID). NOW RECENTLY LAST THREE MONTH HAPPENING EXACTLY LIKE FOLLOWING POST. I HAVE CONTACTED DEALER AND HAVE APPOINTMENT THIS WEEK. (SEE WHAT HAPPENS..) =========================== LATE LAST YEAR (2014) IN OUR KIA OPTIMA 2009 GOT SOME TRANSMISSION ISSUE WHICH IS DIFFICULT TO EXPLAIN FOR. TO ME IT LOOKS LIKE A MANUFACTURING DEFECT WHICH KIA MUST RESOLVE. THIS IS WHAT I EXPERIENCED: IN 2014 OCTOBER, I STARTED FEELING A HEAVY JOLT/JERK WHENEVER I USED THE CAR AND THE ENGINE IS COLD. THE JOLT IS SO STRONG THAT EVERY PASSENGER NOTICED IT. THIS HAPPENS ONLY WHEN I TRY TO SLOW DOWN THE CAR AND IT GETS NEAR TO 20 MPHR. SO THE FACTORS ARE: 1. COLD 2. DOWNSHIFT 3. SPEED 20 MPHR ON SLIPPERY ROADS IT MAY BE VERY DANGEROUS WHICH CAN LEAD TO MAJOR INJURIES. KIA MUST ACCEPT THIS DANGEROUS MANUFACTURING DEFECT BEFORE IT START TAKING LIVES. IT IS VERY ANNOYING ISSUE TOO, IT IS ALWAYS ON MY MIND WHILE DRIVING WHICH IS CAUSING DISTRACTION WHILE DRIVING. KIA MUST TAKE AN ACTION INSTEAD OF SITTING QUITE. THEY MUST ISSUE RECALL THIS TO FIX THIS DANGEROUS ISSUE. NHTSA ALSO SHOULD SUPPORT ALL THE PEOPLE WITH SAME PROBLEM SO THAT PEOPLE CAN BELIEVE THEIR SAFETY STANDARDS. I TOOK MY CAR 2-3 TIMES THERE AND EXPLAINED THE ISSUE, BUT THEY COULD NOT FIX IT SO FAR. IF KIA'S OWN DEALERS CANNOT FIX THIS PROBLEM THEN WHO WILL? THANKS FOR READING MY COMPLAINT AGAINST KIA! *TR
