“Dear NHTSA, I am writing to formally report a serious safety incident involving my 2016 Kia Optima Hybrid, which caught fire and was completely destroyed on October 5, 2025. Incident Summary: While driving on a highway at approximately 65 mph, I noticed that the vehicle was not entering Hybrid Mode, which is abnormal for its typical operation. I reduced my speed to 45 mph, then down to 35 mph as I began to observe smoke coming from the vehicle. At no point did the vehicle show signs of overheating, and there was no Check Engine Light until shortly before I was able to safely pull over. Within moments of stopping the vehicle and exiting with my passenger, the vehicle was engulfed in flames and ultimately burned to the ground. Fortunately, both occupants escaped unharmed. The vehicle has been inspected by my insurance provider; however, I have been waiting over two weeks for Kia to inspect the vehicle or provide any official response regarding a possible cause. This delay is concerning, especially given the severity of the incident and the potential safety risk to other drivers. Vehicle Details: Make/Model: 2016 Kia Optima Hybrid VIN: [XXX] Mileage: 54,300 Date…”

“FOR THE 2ND YEAR, MY KIA WOULD NOT START IN 32 DEGREE WEATHER IN BIG BEAR, CA. THIS IS AN ANNUAL TRIP & TOOK MY KIA.THE LIGHTS, RADIO ALL TURN ON BUT THE ENGINE WILL NOT START. I HAVE TO WAIT UNTIL NOON FOR THE SUN TO WARM UP THE CAR & THEN IT'S BACK TO NORMAL. I HAVE TAKEN THE CAR BACK TO THE DEALERSHIP & HAVE BEEN TOLD THEY CANNOT FIND ANY MALFUNCTION & NEVER HEARD OF ANYONE EXPERIENCE WHAT I HAVE. THERE ARE MANY FORUMS WITH KIA OWNERS COMPLAINING OF THE SAME, BUT CANNOT GET A FIX OR ACKNOWLEDGEMENT THAT THE PROBLEM EXISTS. IT'S BEYOND FRUSTRATING WHEN THE CAR HAS LESS THAN 40K MILES.”

“THE RIGHT PASSENGER HEADLIGHT WON'T WORK I CHANGED THE LIGHT BULB AND IT'S COMPLETELY OFF. AT FIRST WHEN I ATTEMPTED TO CHANGE THE BULB THE LIGHT FLICKERED AND I THOUGHT THAT IT MIGHT'VE NOT BEEN PUT ON ALL THE WAY OR IT MIGHT'VE BECAME LOOSE. BUT THEN IT WENT COMPLETELY OUT CAUSING A ROAD HAZARD AND UNSAFE TO DRIVE AS LIGHTS ARE VERY IMPORTANT. IT ALSO HAS CAUSED ME TO BE PULLED OVER BY MANY POLICE WHEN I SHOULDN'T BE GOING THROUGH THIS OR ANYONE'S ONE ELSE THAT IS GOING THROUGH THE SAME PROBLEM WITH KIA. THIS FIRST OCCURRED WHEN I WAS DRIVING ON THE HIGHWAY COULD'VE BEEN A BAD SITUATION. IT COULD BE A BAD WIRING AS I READ FROM OTHER REPORTS BUT KIA HAS NOT DONE A RECALL. THIS SITUATION SHOULD BE COVERED BY KIA AND NO ONE SHOULD PAY AS IT IS A SAFETY ISSUE AND ACCIDENTS COULD OCCUR”
