While driving during colder weather the car will show HEV (hybrid system) warning and tell you to shut it off. I was in a construction zone with no where to pull over when the car died and lost all propulsion and brakes. This seems to be a common problem on KIA Optima hybrids from 2012-2015.

WHILE TRYING TO PARK THE CAR IN THE PARKING LOT STRUCTURE, THE CAR ACCELERATED BEYOND CONTROL ON IT'S OWN AND HIT THE WALL HEAD ON. I WAS ALREADY IN MY PARKING SPOT AND ONLY FEW FEET AWAY WHEN THE CAR ACCELERATED. THE PASSENGER AIR BAG WAS DEPLOYED AND BODY DAMAGE OCCURRED. EVERYTHING HAPPENED SO SUDDENLY, I AM NOT SURE ABOUT THE SPEED AT THE TIME OF IMPACT. NOTE: THIS COMPLAINT IS A DUPLICATE OF 10620789.

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 Hybrid verdict →
