“The contact owns a 2011 Kia Optima Hybrid. The contact stated while driving 50-60 MPH, there was smoke coming out from underneath the hood of the vehicle. The check engine warning light and other unknown warning lights were illuminated. The vehicle was taken to an independent mechanic, where the engine was cleaned and the spark plugs were replaced; however, the failure recurred while driving. The contact was able to pull into a parking lot and park the vehicle. The vehicle was towed to the residence. The vehicle was then towed to the local dealer and failed to restart. The dealer informed the contact that the vehicle could not be serviced because it was out of warranty. The vehicle was not diagnosed or repaired. The contact related the failure to NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic) and to Kia Campaign Number: SC200. The manufacturer was not notified of the failure. The failure mileage was approximately 131,000.”
“ECU MALFUNCTION CAUSING MISFIRE IN CYLINDER ONE RESULTING IN IGNITION COIL MELTING AND AND CAUSING ELECTRICAL FIRE IN ENGINE BAY WHILE IN MOTION ON LOCAL STREET. VEHICLE IS NOW INOPERABLE.”
“WHILE DRIVING (IN FORWARD MOTION), WITHOUT ANY PRESSURE BEING APPLIED TO EITHER THE BRAKE OR PARKING BRAKE, THE VEHICLE BEGINS TO SLOW ITSELF RAPIDLY LOSING ACCELERATION.; A RUMBLE CAN BE HEARD THERE IS CONSISTENT BEEPING NOISE AND THE VEHICLE BEGINS TO VIBRATE SLIGHTLY. A YELLOW TRIANGLE WITH AN EXCLAMATION POINT AND THE WORDS CHECK BRAKE APPEARS IN THE DRIVERS DISPLAY; ATTEMPTS TO ACCELERATE INCREASES THE RPMS BUT THE VEHICLE CONTINUES TO SLOW RAPIDLY. NOT IDLE AS IF IT WERE NOT IN GEAR, BUT JUST AS IF THE DRIVER WAS BREAKING SUDDENLY. THE ONLY KNOWN METHOD OF CORRECTING THIS IS TO TURN THE VEHICLE OFF AND RESTART IT. HOWEVER, THIS STOPS WORKING AS A SOLUTION AFTER A FEW DAYS AND THE PROBLEM PERSISTS. WHEN THE VEHICLE RESTARTS YOU CAN FEEL THE BRAKE PEDAL RELEASE. THIS HAS OCCURRED RANDOMLY AT LEAST 20 TIMES IN THE PAST BEFORE UNTIL EVENTUALLY IT COULD NOT BE DRIVEN AT ALL. AT SPEEDS RANGING FROM 25 MPH ON NEIGHBORHOOD STREETS TO 70 MPH ON BUSY FREEWAYS. I SINCERELY FEAR THAT IF NOT CORRECTED IT WILL LEAD TO A (POTENTIALLY FATAL) VEHICLE COLLISION. I ALSO TOOK THE VEHICLE TO A NEAR-BY KIA DEALER SERVICE DEPARTMENT IN CA. AFTER MONTHS THE CAR WAS RETURNED AND…”
