This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The contact owns a 2012 Kia Optima. While driving various speeds at night, the low beam headlights failed to illuminate brightly. The illumination prevented the contact from viewing the road while driving. The vehicle was not taken to the dealer or independent mechanic to determine the cause of the failure. The manufacturer was not notified. The approximate failure mileage was 122,597.
I first noticed a problem with my vehicle when the cruise control would randomly disengage while going down the interstate. Then a couple of weeks later I was making a left turn across a two lanes of traffic on a city street. When I first pushed the accelerator the car started to go and then suddenly I lost all acceleration. I let my foot off the accelerator and then pushed back down and was able to go. This was a very dangerous situation as I was stuck in the middle of two lanes of traffic for several extra seconds longer than necessary. A similar situation happened a couple of more time and when I parked the vehicle at home I noticed that brake light was staying on after I got out of the car. I took the car to the local Kia dealership and they replaced the brake sensor which fixed all of the above problems. I would like to not that Hyundai issued a recall on the nearly identical sonata for this same issue and did so years ago and yet nothing for the Optima.
Exiting hwy 71 East bound to woodward decreasing speed the vehicle in front of me had a car cut in front of her. I had a safe distance and slammed my brakes. My brakes did not grab as usual my car did not stop and I hit the vehicle in front of me. I truly believe my brake system failed. I will take my car into Kia when I get it back.
The interior overhead lights periodically come on and go off while operating our 2012 Optima. This occurs with the switch in both on and off position and the lightbulbs tend to become overheated.they do not respond to manual operation, but go off on their own and this malfunction repeats several times in a ten minute drive. Best-case scenario results in the bulbs burning out prematurely, but I believe there is a real chance of a more serious short-circuit and potential interior fire.
