Kia Motors America (Kia) is recalling certain 2010-2013 Kia Forte, Forte Koup, 2011-2013 Kia Optima and 2011-2012 Kia Optima Hybrid and Sedona vehicles. In the event of a crash, the air bag control unit (ACU) may short circuit, preventing the frontal air bags and seat belt pretensioners from deploying.
If the frontal air bags and seat belt pretensioners are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.
Kia will notify owners. For model year 2011 Sedona vehicles, Kia will instruct dealers to verify the ACU part number and, if necessary, install an extension wire harness kit between the ACU Connector and the Vehicle Harness Connector. For all other affected vehicles, Kia will instruct dealers to install the extension wire harness kit. The recall began September 28, 2018. Owners may contact Kia customer service at 1-800-333-4542.

Exterior lighting, brake lights, switchApr 1, 2013
Kia Motors Corporation (Kia) is recalling certain model year 2007-2010 Rondo, model year 2007-2011 Sedona, Sorento and Sportage, model year 2010-2011 Soul, model year 2008-2011 Optima, model year 2010 Forte, model year 2007-2009 Amanti, and model year 2009 Borrego vehicles. Originally, in April 2013, Kia recalled 623,658 model year 2007-2010 Rondo and Sportage, model year 2007-2011 Sorento, model year 2007 Sedona, model year 2010-2011 Soul, and model year 2011 Optima vehicles. In September 2013, Kia informed the agency that it was adding an additional 356,719 vehicles to this campaign. The total number of vehicles being recalled is now 980,377. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake-transmission shift interlock feature preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of PARK without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Kia will send an interim notification to owners in May 2013. When parts are available, owners will receive a second notification and dealers will replace the stop lamp switch, free of charge. Owners may contact Kia at 1-800-333-4542. Kia's recall campaign number is SC098.

Electrical system, Service brakes, Forward collision avoidance, Jan 8, 2023
After driving the car over 15 miles, the Check Brake Light comes on, activating my emergency brake, slowing the car down and preventing me to accelerate. This happens on the freeway, where traffic is fast and my decelerating car puts me and those around me at risk of collision. Once it occurs the first time, it happens again a few minutes later. I have to frequently veer off the side of the freeway, turn off the car, and then turn it on again for the Check brake light to go away and for me to travel once more. This has been a problem for a couple of years with me trying to get the issue repaired, and documented in my visits. Kia and other service operatives have repeatedly not been able to replicate the error in their care, however they never drive it long enough for it to occur. I’ve spent a lot of money now trying to fix this problem and have videos and photos of it occurring. The last time it was inspected they only drove it 6 miles and said there were a lot of little codes going off but weren’t again able to replicate the problem I had been describing. It first appeared 2 years ago and I can feel it start to come on when I’m not able to accelerate my car any further like there is an added resistance. This then amounts to the check brakes display to appear with the emergency brake icon always accompanying it. It makes a scraping, gargled sounds and slows down the car. Overall it has affected the overall drive of the car and braking system as it is growing harder to stop the car when driving. The brakes have been repeatedly checked as well as the fluid and it’s normal, so it should be braking normally. This car has had other issues in the past that have been fixed but this has continued and has been a growing issue that is not being resolved. I’ve googled this issue with others expressing the same issue without ANY viable solution from Kia so I know I’m not alone in this. It’s not safe to drive. Also I tried uploading the videos but it only allowed the pictures.

Vehicle speed control, Engine, Fuel/propulsion system, Dec 17, 2022
As I would drive the vehicle a rattling noise would occur when every time I accelerate from stopping at a traffic light. Then the engine light appeared on the dash board. When I went to have the engine light checked the results came back about an oil gasket. I then got an oil change soon after. The rattling noise and the same acceleration problem still occurred. Soon after it gotten worst to the point couldn’t go faster then 10 mph and then the car kept shutting off.

Engine, Fuel/propulsion system, Dec 6, 2022, fire
While driving our 2011 Kia Optima on I-185 at highway speed, the vehicle suddenly had unresponsive accelerator and had decrease in power. Gauges were all normal range, no warning or indicator lights illuminated. I pulled over to the highway shoulder to clear traffic and placed car in park. Immediately light gray, then black smoke poured out from the hood. My wife and I evacuated the Kia just before the front of the vehicle was engulfed in flames. The engine had been replaced in Sept 2021 due to a previous recall, and up to this incident the Kia performed within normal parameters.
Exterior lighting, Nov 16, 2022
THE LOW BEAM HEADLIGHTS ON THIS VEHICLE ARE EXTREMELY DIM. IT IS DANGEROUS TO DRIVE AT NIGHT. THE ONLY SAFE WAY TO DRIVE IS WITH THE HIGH BEAMS WHICH ENDANGERS OTHER DRIVERS ON THE ROAD. THERE ARE THOUSANDS OF OTHER KIA OPTIMA DRIVERS WITH THE SAME PROBLEM BUT KIA WON'T ACKNOWLEDGE OR FIX THE ISSUE. THIS CAR IS UNSAFE TO DRIVE AT NIGHT.
Electrical system, Service brakes, Engine, Oct 20, 2022
I was driving out of town and when I went to accelerate and the engine had seized, the brakes had locked up and I lost power steering which almost resulted in an accident. On the dash was showing the engine, oil, and esc light, which were not on the dash before and there was nothing wrong or weird going on with the car prior to the first incident to even indicate that something was wrong. Had to get the car towed home then realized there had been a recall on the engine. Contacted the kia manufacturer and they had towed it to a kia dealership where they replaced the engine. Waited 2 Months to get my car back, the dealership let me leave with the ABS and Eps light on the dash, and couldn't give me a reason why the lights were still on. I had it for 3 days, it drove okay and now it no longer drives nor does it start. I was stranded because the car wouldnt start again giving the same issues as before the recall repair was done, with only accessories turning on. On the dash it only shows Engine, Oil, Eps and battery light. Found the Serpentine belt already coming apart and misplaced, found strips of the belt laying in the bottom of the hood. Also had found out the entire engine block ROCKS BACK AND FORTH while car is in motion. If I had driven the car any longer the belt would have completely snapped and would most likely result in an injury or worse. With the Engine movement that is also going to cause other damages to the car and more safety hazards. I have not even known about the engine recall on this car until after everything happened and when the car was purchased no one had notified me in anyway about the recall. Now they refuse to cover towing costs back to the dealership because the "5 year warranty had expired" When this in no way is my fault. Second incident was Oct. 17th 2022.
Engine and engine cooling, Jul 6, 2022
The contact owns a 2011 Kia Optima. The contact stated while driving approximately 25 MPH, the vehicle was consuming an excessive amount of engine oil. The contact was consistently topping off the engine oil. There were no warning lights illuminated. The contact stated that there was no smoke or abnormal odor coming from the vehicle. The vehicle was diagnosed with excessive oil consumption; however, the vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 11,000.
Engine, Jul 3, 2022
My 2011 Kia Optimas engine light started flashing and the car lost all power and had no RPMS over 1000-2000. I took it to the dealership where I was told it had a code P1326 and they replaced a knock sensor. The same day that I picked my car up from them I was going down the interstate and it shut completely off and wouldn’t crank. I had it towed back to the dealership where they said I would most likely need a new engine. A few days later they call and say the engine won’t be covered under the recall because of some hose they claim was leaking for the cooling system. They said it now had a blown head gasket which I’m not sure how because it never ran hot. This is absolutely ridiculous for customers to deal with so many delays and problems just to get the repairs on their vehicle that Kia has agreed to make. If my vehicle needed a knock sensor then obviously the damage to the motor is because of faulty manufacturing of parts and I shouldn’t have to pay for a new motor!
Structure, May 23, 2022
The paint is delaminating and peeling in the section just above the windshield. This started in 2019 and has steadily getting worse. My car color is "Snow White Pearl". I have attached pictures. I had assumed that this was due to the age of the car until I started looking for solutions to fix it and keep it from getting worse. I have found that this is apparently an issue with the paint and is not due to age as there are hundreds of testimonials of other KIA owners with the exact same issue, especially owners with the "Snow White Pearl" paint color.

[XXX] While driving my vehicle it looses power and becomes inoperable at any time and any speed. The brake, engine and oil lights come on simultaneously and there is no longer power to the gas pedal. The vehicle then has to coast to safety off of the road. This is extremely hazardous and could potentially cause an accident. When applying the brakes during this time it makes a grinding sound as if the emergency brake has been engaged. My vehicle has been to the dealership and numerous of time but they say it’s not a problem. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I as driving on the highway and all of a sudden the car would not accelerate. The engine light, oil light, air bag lights etc. all turned on. The speed quickly dropped but I was able to to move into the safety lane. The card finally stalled and would would not start. I tried turning it back on, but the engine would not crank. The lights, radio, AC would still turn on, but the engine would not start. I have maintained it's scheduled maintenance and I was under miles until it's next oil change considering I had just changed it a month ago. I took it to get checked and was advised there was no oil and the engine was seized. I never received a warning the oil pressure was low. My car is over the 10 years and/or 100,000 k warranty as it was purchased 8/2011.

Vehicle speed control, Engine, Nov 27, 2021
On NOV. 26TH 2021, I was driving my car and upon trying to accelorate, my car felt as if it was about to stall out. I pressed the gas and I barely moved. My engine light went on immediately and it's constantly flashing now. The cars RPM's do not go past 1-1/2 RPM's. I can not pick up speed like before, like I should. My car now hesitates and I'm scared to drive it. I feel that it's dangerous cause I can not keep up with traffic. I found a RECALL letter that I have from July 12, 2017 in which I took it to the dealer at that time I received it. I alo found 2 other recall letters ( see pics ataached). I guess at that time when they checked it nothing was wrong BUT now I am having an issue and I feel it could be related. The recall number is: 17V224 follow up letter of one of the recalls. The recalls prior to that does not have a # on it: it states: ENGINE CONNECTING ROD on of the recalls. I'm hearing some knocking but it just happened and I havent driven it since Nov. 26th. a.m.The code that comes up as P1362, knocking sensor and can be a number of other things. And everything I read says the KNOCK sensor detects vibrations indicating an onset of excessive connecting rod bearing wear. and can severly damage the engine. I'm very concerned and I feel that this recall back in 2017 is now happening to my car. I have uploaded the recall I have in my possession. According to William Garcia( Billy ) the service guy I always usually worked with at Gunther Kia, all of my recalls were checked and soem weere fixed. These particualr ones he said were done and or checked but nothing was repaired as you'll see in my history of service on recalls with them.

2011 Kia Optima caught on fire while driving. Car started smoking which was the only indication something was wrong then all the dashboard lights came on and brakes no longer worked. About half a block later I put the car in park and it slowed down enough for my 3 kids to jump out although the car was still moving. I was able to exit a few seconds later when it came to a full stop. Within minutes it had flames coming from under the hood that continued until the fire department was able to put it out. They said something electrical had caused the fire.

I pulled out from a parking lot into traffic and not less then 5 seconds later the car sputtered once and then completely shut off in the middle of traffic. I was able to coast into the bike lane but was in fear that I would be rear-ended and possibly might incur injuries or harm would be caused to others due to the the manner in which I had not control or could prevent an accident occurring. The vehicle was towed to a mechanic and was diagnosed on with Engine Failure/Engine Lock Code P1326 w/ Internal Kia Code SC147. The vehicle will not move. There were no warning lamps, messages or other symptoms that would indicate engine failure and risk of a possible accident.
