Problems with 2012 Kia Optima EXTERIOR LIGHTING

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.

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.

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.

Tl* the contact owns a 2012 kia optima hybrid. the contact stated that the vehicle experienced electrical failure and unintended acceleration. the contact stated that the vehicle accelerated and decelerated independently. the contact stated that there was an intermittent failure with headlamps. the contact also stated that the vehicle lunged forward while driving. the vehicle was taken to power kia dealer, (3705 market st ne, salem, or 97301, (503) 585-7333) and was informed that the battery needed to be replaced. the vehicle was repaired however, the unintended acceleration recurred. the vehicle was taken back to the same dealer and informed that the headlamps light switch caused the battery to drain. the battery was replaced. the vehicle was repaired. the failure recurred. the contact stated that the vehicle was taken to the same dealer four times. the manufacturer was not made aware of the failure. the failure mileage was approximately 77,874.

The low beam headlights are dim and make it difficult to drive safely at night.

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.

Tl* 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.

Tl* the contact owns a 2012 kia optima. the contact stated that the headlights failed to illuminate and there was extremely poor visibility. also, the oil light randomly illuminated several times. the dealer (ossett kia south, 2680 mt moriah rd, memphis, tn 38115, (901) 328-8173) was unable to determine the cause of the failures. the contact replaced the headlight assemblies more than five times, but the visibility was still poor. the contact also noticed an abnormal odor in the vehicle. the dealer indicated that without the check engine indicator illuminated, they would not replace the catalytic converter. the contact stated that the warranty expired without the part being replaced. the fan also failed to function, but the failure was not remedied. the dealer also performed a repair per an unknown recall regarding the steering; however, the remedy failed to provide a solution for the steering coupler and the steering wheel was no longer straight. also, the sun roof and moon roof glass had a crack going down to the driver's side of the vehicle where it met the windshield. there was also an abnormal noise progressing due to the failures. the manufacturer and dealer were notified of the steering failure, headlight failure, and moisture in the rear camera. the failure mileage was not available.

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.

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 $2500.00! 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!

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. *tr
