Filed Dec 19, 201871,653 vehiclesKia Motors America
Defect. Kia Motors America (Kia) is recalling certain 2011-2017 Optima, 2012-2017 Sorento and 2011-2018 Sportage vehicles that previously received an engine replacement under recall number 17V-224, warranty, or the Knock Sensor Detection System (KSDS) Product Improvement Campaign. The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned or improperly torqued during the engine replacement procedure, possibly causing a fuel leak.
Risk. A fuel leak in the presence of an ignition source can increase the risk of a fire.
Remedy. Kia has notified owners, and dealers will inspect and replace the fuel pipe, as necessary, free of charge. The recall began January 17, 2019. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC172.

Filed Jun 1, 2018507,587 vehiclesKia Motors America
Defect. 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.
Risk. 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.
Remedy. 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. Kia's number for this recall is SC165.

Defect. Kia Motor Company (Kia) is recalling certain 2011-2014 Optima, 2012-2014 Sorento and 2011-2013 Sportage vehicles. Machining errors during the engine manufacturing process may cause premature bearing wear within the engine.
Risk. Bearing wear may result in the engine seizing, increasing the risk of a crash.
Remedy. Kia will notify owners, and dealers will inspect the engine assembly, and replace the engine if necessary, free of charge. The recall began June 20, 2017. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC147.
Defect. 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.
Risk. 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.
Remedy. 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.

I own a 2011 Kia Optima, VIN [XXX]. My vehicle was taken to Rockwall Kia on August 25, 2026, for completion of NHTSA Safety Recall 23V-652 / Kia SC284TF involving the HECU fuse. The dealership replaced the HECU multi-fuse and label kit. Before the recall repair, the vehicle was operating normally. The same day I picked the vehicle up after the recall repair, the vehicle began dying while I was driving. I also noticed a burning smell. I returned the vehicle to Rockwall Kia. Their August 31, 2026 repair order documents my complaint and states that the vehicle would die while driving and that this problem “DID NOT BEGIN UNTIL AFTER RECALL COMPLETED.” The repair order instructs the technician to inspect whether the recall was completed properly and diagnose the concern. I am concerned because the HECU recall involves an electrical short/overcurrent condition and Kia's recall documentation specifically identifies burning/melting smell and smoke as warning symptoms. I am requesting that NHTSA document this complaint and review whether the post-recall stalling and burning smell could be related to the HECU recall repair or indicate a continuing safety problem.

I was having trouble with my left driver tire. 2 mechanics went to test drive the car to see what the problem was. As they were driving, the car died. They got it started but it ran horrible back to the garage. When they pulled in the driveway of the garage, the car started on fire. It was an engine fire but undetermined what exactly was the cause. The vehicle was looked over by the insurance claims adjustor. I am not sure if sluggish driving had anything to do with the fire. The car is totaled.
Engine

The vehicle's engine had previously been replaced once under Kia's Theta II engine recall/warranty program approximately five years prior to this incident. On the date of failure, the replacement engine catastrophically failed while the vehicle was in operation, resulting in the engine developing a hole in the engine block and becoming inoperable. Prior to the failure, the vehicle exhibited a "check engine" warning and symptoms consistent with connecting rod bearing failure. Diagnostic trouble codes P1326 and P0303 were present upon inspection at an authorized Kia dealership. The failure occurred at approximately 198,000 miles. This is the second engine failure on this vehicle, both consistent with the known Theta II engine defect involving premature bearing wear and connecting rod failure that has been the subject of prior NHTSA recalls and a related class action settlement. The failure created a risk of sudden loss of engine power while driving, which can pose a safety hazard in traffic. The vehicle was inspected by the authorized Kia dealership, which confirmed the hole in the engine block and the diagnostic codes noted above. The engine and related repair estimate are available for inspection upon request. A warranty claim for repair coverage was submitted and denied by the manufacturer, citing insufficient maintenance documentation, despite this being the vehicle's second occurrence of the same underlying defect.
Air Bags
Filed Jul 13, 2026OH
About six months ago, I lost the heated steering wheel functionality in my steering wheel, then from there, I slowly lost functionality like cruise control, and the most recent now my airbag and horn do not work. If you press on the horn, it is silent, and the airbag light has been illuminated consistently for the last couple of months. I had this issue diagnosed and it came up with the codes of B1346. And B1481. After some research, these issues are the result of a bad clock, spring and cause the airbag and horn not to work. Additionally, this issue is known to this model the 2011 Kia Optima, and has been recalled in most production cases of this vehicle, but my vehicle is not included. I received a quote for $876 from a dealership to get this corrected, but it should be included in the recall.

I have replaced the headlights in my 2011 Kia Optima multiple times but no matter what without the brights on, the road is not at all illuminated making it impossible to see at night. When you look at the car head on the lights look as if they would be incredibly bright, but I believe due to faulty reflective lining on the interior of the headlight housing, even though the bulb may shine brightly, it does not get reflected properly onto the surface of the road causing serious safety concerns.

I am submitting a complaint regarding my 2011 Kia Optima (VIN: [XXX] ), which is currently experiencing significant engine issues and is undrivable. This issue is currently being reviewed under Kia Case #XXX. This vehicle is part of the Theta II engine group that has been the subject of recalls, service campaigns, and extended warranty coverage due to known engine defects, including rod bearing failure and potential engine seizure. The vehicle has also received the Knock Sensor Detection System (KSDS) update associated with these known issues. My vehicle is currently at the dealership and has been there since March 10, 2026. It is not drivable, and I have been without transportation during this time. The dealership has diagnosed the issue as oil consumption; however, Kia has denied coverage, stating that oil consumption is not related to rod bearing failure. Kia has not confirmed whether a full internal engine inspection was performed to rule out rod bearing damage, nor have they confirmed that a Techline engineering review has been conducted. Given the known history of engine defects in this model, I am concerned that the current condition may be related to internal engine failure that has not been properly evaluated. Oil consumption can be a precursor or symptom of internal engine damage, and I do not believe the issue has been fully or adequately diagnosed. Additionally, my vehicle has an open safety recall related to potential engine compartment fire risk, which further r

While driving the Kia on the highway (in the passing lane on Route 93, Boston, MA), the hood of the car flew open and shattered the windshield. Prior to getting into the vehicle, there was no notification, warning light/display, that alerted to the hood or anything else not being 'closed', no rattling of the hood either. The hood blocked my entire vision with the exception of a small area below, where I miraculous got over to the breakdown lane without causing any accident. When I got out of the car, the hood was bent and the second latch was loose. It did not hold its shape. Called the police and the insurance company, the car was deemed a total loss. This incident occurred on January 31, 2026 at 10:05AM. The conditions were dry and sunny. The state trooper said that this incident could have had serious safety consequences to the driver and others since no one expects a hood to fly open, block visibility...this highway is a busy road and could have impacted several other vehicles on the road. We no warning lamps/message- this was traumatic- this put the safety of the driver and the public at great risk.

I was driving in the highway doing about 80mph passing a semi truck when all of a sudden my vehicle went from 80 down to 50 mph and I was jerked forward. I thought I was rear ended but when I looked in my rear view mirror no cars were behind me. I looked down and noticed my engine light, battery light and oil light were on and turned down my music and could hear my engine was no longer running. Thankfully there wasn't much traffic and I was able to coast to the side of the highway and turn the car off. If someone would have been behind me I am confident I would have been hit. The problem has since been confirmed by a dealership and info has been sent to Kia. The dealership was unable to provide me with a loaner car as "they had none available" so I contacted Kia corporate and they are telling me my only option is that I have to come out of pocket for a rental and they will reimburse 40$ per day. I don't think especially since I had to pay for 2 nights in a hotel as I was stranded, a few hundred dollars for a tow that I should have to pay anything as the issue with what happened to my car is the fault of Kia at the time of manufacturing. At this time I have been without a vehicle for 1 week. I was told by the dealership today that they sent all of the required info over to Kia to get word on whether the lifetime extended warranty would pay for my car to be repaired. The previous owner before me did have the KSCS update performed as mandated by Kia. My problem is I am already o

Not sure what to do. I scheduled a recall fix for this HECU fuse with our city KIA dealer. When I went they told me I'd have to come back because they didn't have one in stock. No one ever called me again so I phoned to make an appt and the service manager never gets back with me at this dealership. Next dealership is an hour away. Please advise. Thank you.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
