My 2012 Kia optima headlamps are extremely dim, even though I-??ve replaced the lightbulbs with the highest possible lumens, multiple times, the headlamp assembly continues to dim. This requires that I ride with my high-beams on to drive at night. The lights have been dimming for more than 20,000 miles, but they are almost useless at this point.

My car started losing its lights one by one. I lost the front right light first, then yhe right back side light, and now the brakes lights. I replaced all the bulbs and still does not work. Then my car just cut off while driving with no notification. I towed it in to Mavis. They checked and said the battery was not keeping charge. I paid to replace the battery, belt and alternator. Four days later my check engine light, battery indicator, airbag indicator, door indicator came on and still is on.

Because the brake stopper or brake switch are messed up and my brake tail light stays on all night causing it to drain the battery If the car is braking while I-??m driving it and the traction control light comes on and the speed is decreasing as I-??m driving because the car is braking on it-??s own it has nothing to do with the lights Nor the battery the root of the issue is the brake line because the tail light will not cut off because the brakes are still engaged even when the car is off causing the tail lights to stay on so the lights is what is draining the battery the lights stay on all night in a car the battery dies but the battery nor the lights is the issue it-??s the brakes

I was driving on the highway and all of sudden my car started decelerating. I looked in my rear view mirror and noticed the brake lights were illuminated although I was NOT pressing the brake pedal.

Transmission has a hard pull when it down shifts from third gear to second gear and a harder pull on first gear this is a automatic transmission. In regular gears going in drive would actually do fine I noticed a week later when I was out driving for about an hour that the car would not go past second gear so I pulled off the road and had my car towed. The vehicle has never had any dashboard lights come on currently my car is in limp mode and will only go in reverse takes a few seconds to initiate an engage to go into first gear.dealership does not really want to look at the vehicle if it does not have a check engine light code I have no idea what is wrong with this transmission I have 168,000 miles. It should give you some type of warning that something is going on with your transmission but it does not even light up on your dashboard if you go to press the pedal to accelerate it does not want to accelerate I just recently had my catalytic converter changed out so I know it is not that the gears on the transmission will not go past second gear now it is in what they consider limp mode or default mode someone really needs to look at the transmission on all the 2012 Kia Optimas I have been seeing a lot of issues with these cars the lights that are considered as the low beams are not very bright either I just recently had those changed and new ones put in they do not give you enough light if you're driving at night this is a safety hazard

Lowbeams seem weak/dim. Research showed via Kia"2011-2013 my Optima/Optima hybrid headlamp assembly new vehicle limited warranty extension" that the reflector in the low beam headlamp housing may deteriorate over time, resulting in a gradual dimming of the low beam headlamp. Unfortunately, it only pertains to vehicles manufactured in Korea. My vehicle was assembled in Georgia, but I believe the headlight housing is the same for both locations. Bottom line, my low beams have the same issue and driving at night is unsafe due to the limited visibility. I personally completed the procedure's inspection as outlined in the tsb (attached) and determined my vehicle has this problem, but since mine was assembled in Georgia they won't replace at no cost to me.

I have reason to believe that my car has been hacked due to an incident that occurred approximately one week after being aggressively followed by a mysterious black Nissan SUV with pitch-black tinted windows at my work location. During the incident in question, I was on the phone with 911, with the bluetooth of my car and phone on and connected, calling about a red car that appeared to be following me. I drove around my block and lost the red car but when I returned back to the street where I live, I slowed down as I noticed a slow-moving black SUV with pitch-black dark tinted windows (reminding me of the black Nissan SUV that I encountered a week prior at work). I remember its headlights being off. This time, I was in close proximity to the black SUV- it was on my left side driving the opposite direction and it also appeared to slowed down and got parallel to my vehicle). When my car and the black SUV where almost next to each other, all the interior lights of my vehicle turned on and I heard a sound that sounded like all the doors unlocked. As a petite female who was driving alone at 10pm or later that night on an empty back street, I got terrified and quickly pushed on the gas to get away from the black SUV. With all the interior lights on while trying to drive at night, I had no visibility whatsoever, so I kept pushing the light switch by the driver's side, but no matter how many times I moved the switch, the interior lights did not turn off. After driving, I estimate, 1000+ feet, the interior lights turned off and I regained visibility. At that point I could see my apartment was coming up so I quickly drove into the gated parking area of my apartment complex. As I recall the incident, the light switch was on "door" when I was attempting to turn it off while driving. This incident reveals security/safety vulnerabilities in my vehicle.

On feb18 2020 head lights again stopped working new bulbs were put in oem replacements light go off when ever they want this is extremely dangerous if your a rural roads interior light stay on or go off on there own but mostly it's the head light that work when they want to this issue happens when driving and when stationary Kia has to do something to repair the problem this isn't a wear and tear people's this is subpar craftsmanship on a safety issue and I'm afraid someone will die. I have read other complaints where the car owners payed $400 to replace the wiring and bulbs only to have it happen again. My other issue is that Kia used a plastic star locking bearing in the steering column that broke and I had to fix at my expense mechanic said it's a problem with the cars. When driving the car making a turn you would feel the grinding in the steering wheel and hear clicking. This was on regular city paved streets.

Issue started 2 months ago. Noticed that vehicle acceleration is sluggish. Sometimes I have to take foot off the acceleration pedal then depress it again in order for vehicle to accelerate. Acceleration is unreliable and dangerous. Electronic stability sensor also started lighting up and cruise control became inoperable. Also noticed that my tail lights lit up on its own (and did not turn off) while vehicle is parked and fob not near vehicle, draining the battery. Police came by in the middle of the night to report that my tail lights were on. Tail light did not turn off when pressing the fob unlock/lock button. Had to restart the engine, drive around the block then turn off engine before the tail lights came off... but it turned back on again on its own that same night (in the middle of the night) and had to repeat the process. My battery was drained and had to replace it 3 days ago. I thought it was a battery problem (and was informed by dealer that it was probably a battery related issue) but problem persisted. Read reviews and this seems to be a running complaint with issues on brake pedal stopper or brake sensor stopper. Will bring vehicle to dealer in the morning.

My airbag light turned on and stays on while driving. My interior 3way switch light randomly turns on and stays on while driving and won't shut off until the car is off.

2012 Kia Optima ex with 48000 miles now driver-side headlight stopped working, so as of now I am driving with passenger sidelight in combination with parking lights. Buying Kia Optima is the biggest mistake I have ever done, it seems every month something goes wrong with this vehicle. Surprisingly NHTSA has not taken any action as per Kia Optima well known defects.

About 4 years ago the headlights on my 2012 Kia Optima sx starting getting dim. I took it in to the dealer and they replaced bulbs which made no difference. I took it in again about 2 years ago because it was becoming difficult to see at night. They couldn't figure out the problem. They had my car overnight so the service tech drove it that evening to see how bad it was. He told me that he turned up a dark road, turned the car around, flipped the high beams on so he could find his way back to the dealership. He told me that it scared the you-know-what out of him and he was sorry but all he could do is replace the entire headlight assemblies and it would cost me $2500! I went online to see if others were having this problem and I see hundreds of complaints about this problem. I no longer drive the car at night and have to rely on my husband for transportation after dark. I might try to trade the car in for something with real headlights but I'm afraid that I won't be able to trade it in this condition. I did find a tbs #ele181 that says it's part of a warranty extention wty014 that replaces the headlights for this very condition on my car model and year but when I called the dealership they said it only applies to Korean made vehicles. Mine is an american made Kia that, obviously, has the same issue. Why wouldn't all Kia Optimas with this extremely hazardous problem be eligible for this warranty extension? help! I'm at my wits end!

Front low beams very dim, can barely see at night. Have to use high beams in order to see, which is dangerous to on-coming traffic. I have read on various forums that this is a well known issue due to a defect and that the cost is upwards of $2K to fix when this is a hazard and should be covered due to manufacturers defect.

Original hid headlights became dim to the point it failed a Virginia state safety inspection. Dealer service department states the reflective material in the headlight housing has diminished.
