HEV Warning light comes on and says HEV malfunction, stop car. Within seconds the car shuts off and has no brakes and then stops in road construction, blocking up an entire lane of traffic, as there was no shoulder because of barricades. I panic as I can’t get out without getting ran over. After sitting for 5 minutes, car restarts and drives away ok. Car has done this off and on for 2 years. After the first incident, I took it to Kia of New Bern who charged me $400 to “update software” according to a TSB, even though it was under warranty. After getting the car back, the next day the warning came back on. I called Kia of New Bern and they said they will charge another diagnostics fee I couldn’t afford, so I didn’t go back. There are many others who have had the same issue with their KIA Hybrids. These cars are a danger to their drivers and the unknowing public who share the roads with them. KIA Should be ashamed of the amount of cars experiencing this issue and their lack of solutions to fix it.

The contact owned a 2014 Kia Optima. The contact stated that as he attempted to merge onto a highway at 45 MPH, the brake pedal and steering wheel locked up upon the depression of the brake pedal without warning.

HEV LIGHT CAME ON DASHBOARD STATING "CHECK HYBRID SYSTEM. STOP VEHICLE AND TURN OFF ENGINE". VEHICLE WAS IN MOTION IN CITY ON TRAFFIC LIGHT AND SUDDENLY GOT THAT AND CAR STOPPED IN 15 SEC AND COULD NOT MOVE ANYMORE. LUCKILY IT DID NOT HAPPEN ON HIGHWAY CAUSE 15 SEC IS NOT ENOUGH FOR SAFELY STOPPING! WITNESSES HELPED TO PUSH THE CARD TO THE SHOULDER APPROXIMATELY 100 FEET. ELECTRIC BRAKE SYSTEM WAS LOCKED AS WELL CAUSE OF HEV SYSTEM STOPPED SUPPLING THE POWER. KIA CONCORD REPLACED THE SAFETY PLUG ASSY-MALE 125 AMPS TO 150 AMPS (PART # K 37586 4R002). CAR HAD ONLY 82K. AS FAR I SEE THIS IS A COMMON ISSUE AND IF MANUFACTURER IN ALL CASES UPGRADES IT TO HIGHER FUSE, THEN THIS IS A REASON FOR RECALL. NOW I WARRY ABOUT NEXT ELECTRICAL ISSUE THAT CAN CAUSE THAT FUSE.

I WAS DRIVING ON THE HIGHWAY GOING 65 MPH AND AN ALERT POPS UP. IT SAID "POSSIBLE BMS CONDITION." I IMMEDIATELY PULLED TO THE SIDE, BUT ALSO NOTICED MY CAR SPEED REDUCING. I SAFELY GOT INTO THE RIGHT SHOULDER AND THEN THE CAR STEERING WHEEL FROZE UP. ANOTHER ALERT TO CHECK BRAKES WENT ON. I PUSHED THE BRAKES OVER AND OVER TO GET THE ALERT OFF. IT THEN OVER A TIME SPAN OF 3-5 MIN STARTED TO SLOWLY RUN LOW ON ELECTRICITY BECAUSE THE HAZARDS LIGHTS WERE BLINKING SLOWER. I GOT IT TOWED AND WAITING TO SEE WHAT IS THE PROBLEM. BEEN LOOKING IT UP AND MOST LIKELY IT'S THE FUSE IN THE BACK TRUNK UNDER THE COVER UNDERNEATH. *TR

WHILE DRIVING MY CHECK BRAKE LIGHT WILL COME ON INTERMITTENTLY. SEEMS TO HAPPEN MORE FREQUENTLY WHEN ITS WARM OUTSIDE. THE TRACTION CONTROL LIGHT ALWAYS COMES ON AT THE SAME TIME. THE BRAKE LIGHT WILL GO OFF AFTER THE CAR IS TURNED OFF AND RESTARTED, THE TRACTION LIGHT WILL STAY ON FOR AWHILE. SOMETIMES IT WILL GO OFF AFTER A FEW MILES, OTHERS IT TAKES A DAY TO GO OFF. ONLY DIFFERENCE I CAN SEE WHILE DRIVING IS THAT BEFORE IT COMES ON THE BRAKES WILL GRAB HARDER THAN USUAL. THE LIGHTS ONLY COME ON WHEN THE CAR IS IN MOTION OR IMMEDIATELY AFTER COMING TO A STOP. NEVER WHEN IN PARK. THIS STARTED A FEW DAYS AFTER I PURCHASED THE CAR. I'VE HAD THE CAR AT THE KIA DEALERSHIP MANY TIMES FOR THIS ISSUE AND THEY HAVE NEVER FIXED THE PROBLEM.

AND WHILE DOING SO, WITH MY FOOT ON THE BRAKE THE CAR LUNCHED BACKWARDS WITH A JERKING MOTION, LIKE IT WAS TRYING TO DO 2 DIFFERENT THINGS ATONE TIME, AT FULL RATE OF SPEED AND DOING SO, IT BACKED INTO THE VEHICLE TO MY LEFT, THE CAR ACTED LIKE IT HAD A MIND OF IT'S OWN.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2014 Kia Optima verdict →
