“tHE ENTIRE CAR FAILED. cAUGHT ON FIRE FROM THE CONSOLE AND PASSENGER SEAT WHILE DRIVING ON 1-15 . 8.15.2025 . Car filled wit black moke and fire.l was driving blind. brakes failed, power failed, burning the entire time. I somehow got out of burning vehicle and ran about 100 yards and watched the car explode!! Had car tuned up at Findlay Honda whede it was bought, 4 months ago, and they said it was fine... fire and police both told me i should not be here. Since, my life is in shambles. No car, no ID for a motnh, no license for 3 weeks. I bought car in 2023--- car was recalled in 2020. But was it and if it was, why did this EXACT problem occur? Someone must be responsible. On anxiety pillxs”
“My Kia had be under an unresolved recall that can cause a fire, not only putting myself and my family, but other drivers at risk. I have a toddler who rides with me and would be extremely hard to get out of a car seat if the car caught on fire, as such I have reduced driving with them to ensure safety, but this is an issue that cannot continue and I should not have to put myself and others at risk. I cannot afford to buy a new car and should not be forced to due to a manufacturing issue”
“The contact owns a 2015 Kia Rio. The contact stated that while driving at 30 MPH, he observed smoke emanating from the engine compartment, prompting him to pull to the shoulder of the roadway and evacuate the vehicle. After a visual inspection of the engine compartment, the contact observed flame jutting up from the engine. Local emergency services arrived and were able to extinguish the flames but did not provide details on a possible cause for the fire. The check engine warning light was illuminated. The vehicle was towed to a tow yard but had yet to be evaluated by the insurance provider. The contact was unaware if a fire report had been filed. A police report was filed, but no injuries were reported. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic); the VIN was included, and parts were available, but the vehicle had not been repaired. The manufacturer was not notified of the failure. The failure mileage was 160,000.”
