What 748 owners told NHTSA about the 2016 Kia Optima Phev

While driving, the vehicle suddenly developed a loud knocking noise from the engine. Within one block the vehicle began smoking heavily from under the hood. I pulled over, opened the hood, and flames were visible. This is a 2016 Kia Optima with the 2.4L Theta II engine. Approximately one year ago the original engine seized and was replaced by a Kia dealer under the Theta II engine recall (SC172/SC147) and class-action settlement. This is the second catastrophic failure of a Theta II engine in this vehicle. The replacement engine has now failed in the exact same manner as the thousands of other documented cases — rod bearing failure leading to knocking, overheating, and engine compartment fire. The dealership (Fowler Kia of Windsor, CO) inspected the vehicle and quoted over $6,000 in repairs (melted engine wiring harness, ECM connector, battery cables, airbox, intake boot, etc.) while claiming the fire was “unknown cause/not the engine,” despite the clear knocking immediately preceding the fire. Kia Consumer Affairs has an open case but has not yet resolved coverage. This is a known, ongoing safety defect covered under multiple NHTSA investigations (PE21004, EA22002) and Kia recalls. I no longer feel safe in this vehicle and am requesting immediate investigation and inclusion in any expanded recall or remedy.

I was told that my engine had a recall on it so I had an upcoming appointment with Kia in like 2 weeks for them to check my engine but the car didn’t make it. I was driving my car on interstate 20 my car had began to have a bad chemical smell and started smoking so I pulled over on the interstate and my car was in flames. Me and my daughter was in the car we could have lost our lives thank God we were able to make it out just in time. The fire department came and made a report on the incident. It wasn’t any engine light on at the time. I have contacted Kia about the tragedy that has happened but nothing has been resolved yet.

On July 4th, my vehicle lost engine power and flashed a quick prompt of "engine warning" before turning off completely, smoke from under the hood which resulted in a fire. I was able to extinguish it fortunately. I have since discovered there are three open recalls, which I received no notification about. I frequently check for recalls and all sites say there are none.

NHTSA ODI 11360206

ON 1/12/2020, I WAS DRIVING MY CAR 2016 KIA OPTIMA FROM ALPHARETTA TO DECATUR TO ATTEND CHURCH. I PULLED INTO THE PARKING LOT OF THE CHURCH AND PARKED. A FEW SECONDS AFTER I PARKED, I BEGAN SEEING LOTS OF SMOKE COMING FROM THE RIGHT PASSENGER SIDE OF THE CAR. THE POLICE MEN WHO WERE IN THE PARKING LOT DIRECTING TRAFFIC ASKED ME TO GET OUT OF THE CAR QUICKLY AND BEGAN ATTEMPTING TO QUENCH THE FIRE WITH A FIRE EXTINGUISHER. SHORTLY AFTER, THE DEKALB FIRE DEPT ARRIVED AND FOUGHT TO PUT OUT AND CONTAIN THE FIRE. IT WAS THEN TOWED TO THE TOW YARD. I CONTACTED MY INSURANCE COMPANY RIGHT AWAY AND AFTER A FEW DAYS OF INVESTIGATION, UNFORTUNATELY, MY CAR WAS DEEMED A TOTAL LOSS. NEXT DAY, I CHECKED MY VIN # TO SEE IF THERE ARE ANY RECALLS BY KIA THAT I WAS NOT AWARE OF, BUT THE RESULTS CAME BACK SAYING 'NO RECORDS' AND '0 RECALLS FOUND'. ON 1/15/2020 AT APPROXIMATELY 12.50PM, I CONTACTED KIA CORPORATE AND FILED A COMPLAINT AND I WAS INFORMED WHEN I GAVE MY STATEMENT OVER THE PHONE THAT THERE WAS AN ' OPEN CAMPAIGN PI 1802 ECU UPGRADE' AND AS ADVISED BY THE KIA CUSTOMER SERVICE REP THAT HE WILL BE FORWARDING MY COMPLAINT TO A THE NATIONAL DEPT AND THEY WILL GET BACK TO ME. A KIA REP ASHLEY CONTACTED ME AND ADVISED KIA ENGINEERS WILL LIKE TO INVESTIGATE WHAT HAPPENED. AFTER 3 WEEKS OF WAITING, THE REP CONTACTED ME STATING THEY WILL LIKE TO PAY OFF REMAINING BAL ON MY CAR, AND PERSONAL ITEMS. THEY WILL NOT HELP ME WITH GETTING ANOTHER CAR AND I DECLINED BECAUSE I LOST EVERYTHING AND INCURRED A GREATER DAMAGE. THEN THE KIA REP WROTE ME STATING THAT THEY ILL NO LONGER PURSUE INVESTIGATING SINCE I REFUSED ACCEPTING $1001 MY LEFT OVER BALANCE OWED TO THE LENDER. I AM VERY DISAPPOINTED ON HOW KIA HAS TREATED ME LEAVING ME HANGING AFTER SUCH A GREAT LOSS. I AM SEEKING LEGAL ACTIONS SINCE KIA HAS REFUSED TO COME TO A SUITABLE RESOLUTION.
