Kia Optima 2013 — Problemas relatados

Vehicle Safety Complaint – 2013 Kia Optima EX – Electrical Fire In XXX, our 2013 Kia Optima EX experienced a serious electrical fire originating in the driver's compartment, in the vicinity of the driver's floor and seat-belt area. The fire required the use of a fire extinguisher to extinguish the flames and prevent further damage. This was an unexpected and extremely dangerous incident that presented a significant risk of injury to the vehicle's occupants and potentially could have resulted in the complete destruction of the vehicle. The vehicle was subsequently transported to Kia of [XXX], where it is currently undergoing repairs. The damage reportedly involves the vehicle's main electrical wiring harness, with anticipated repair costs exceeding $5,000. Although the vehicle is approximately 13 years old, an electrical fire involving the main wiring harness raises serious concerns about the safety and integrity of the vehicle's electrical system. Such an incident should not be considered an expected consequence of ordinary vehicle aging. I am submitting this complaint to request that NHTSA document and evaluate this incident as a potential vehicle safety defect and determine whether similar electrical fires have been reported in this model or related Kia vehicles. I am particularly concerned about the potential for serious injury or loss of life if a similar incident occurs while a vehicle is occupied or in operation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2013 Kia Optima. While driving at 65 MPH, the vehicle lost motive power but continued to drive under reduced power, with the check engine warning light illuminated. The failure nearly caused a crash. The vehicle was taken to O'Reilly's, where three knock sensor codes were retrieved. The vehicle was then taken to the dealer and was repaired under NHTSA Campaign Numbers: 23V652000 (Service Brake, Hydraulic), 22V093000 (Fuel System, Gasoline), and 22V560000 (Structure). The manufacturer was notified of the failure by phone. The failure mileage was approximately 125,055.

Air bag light is on the panel & is not enabled & buttons on steering wheel that adjust the volume and stations have stopped working unless the steering wheel is turned all the way to the left. Believe it is a faulty spring in the steering wheel.

I own a 2013 Kia Optima SXL. While the vehicle was parked and there was no collision, crash, impact, or other event that should have caused the airbags to deploy, the airbags unexpectedly deployed on their own. The deployment caused damage to the vehicle, including damage to the windshield. The airbag also hit me while I was sitting in the passenger seat, my children were also in the back seat. All of our ears were ringing for 24hours, I went to the hospital to get a CT scan for the pain I felt in my face, ear and head. This occurred without the vehicle being involved in an accident. I have photographs and documentation of the vehicle and the damage and can provide additional information if needed.

Despite documenting this catastrophic internal mechanical destruction, the authorized franchise dealer has issued a written directive instructing the driver to operate this structurally compromised vehicle on public roads for a 1,000-mile oil consumption test with explicit instructions not to add, check, or have anyone service the engine oil level. Operating an engine running dry with verified cylinder wall gouging and unstable timing chains creates an imminent, severe safety hazard for the occupants and other motorists, including sudden highway engine lockup, loss of power steering, or vehicle fires. The vehicle underwent Safety Recall Campaign SC147 in 2017, which carries a court-mandated Lifetime Warranty Extension on the block for core failures. The dealership is forcing an unsafe vehicle modification and dangerous roadway test to evade standard warranty coverage processing. A complete 11-invoice history proves this defect originally manifested and was logged by a technician at 96,738 miles while fully inside the standard factory coverage window.

Gas smell from under the hood. When taken to the dealership it was diagnosed as the high pressure fuel line. NOTE: The high and low fuel lines have recalls that impact this vehicle make, model, and year BUT not this VIN.

The contact owns a 2013 Kia Optima. The contact stated that the vehicle was unable to start due to the battery being drained from the Hydraulic Electronic Control Unit (HECU) remaining on while the vehicle was turned off. After recharging the battery, the HECU made a buzzing sound while the battery was no longer charging. Additionally, the vehicle went into LIMP Mode while driving, and the ABS, traction control, and several other unknown warning lights were illuminated. A burning odor was inside the vehicle. The contact was concerned about a fire risk. The vehicle was taken to the dealer and determined that the HECU had failed and needed to be replaced. The dealer requested maintenance records for the vehicle. The manufacturer was notified of the failure by phone, and a case was filed. The failure mileage was approximately 111,000.

Module 1 7.5 amp fuse continues to short and blow over and over again. Known issues with auto headlamp leveling sensor. Problem continues to happen. Lose my highbeams, shift lock, rear defrost, rearview auto dimmer, steering wheel controls. Anytime the fuse blows

Both front door lock actuators failed within a one month period. It is a safety issue because the actuator is failing in a way that can prevent the door from opening, closing, properly latching and locking. The vehicle is available for inspection. I have taken it to a mechanic to confirm the failure.

The contact owns a 2013 Kia Optima. The contact stated that while driving or while the vehicle was parked, there was an abnormal fuel odor inside the vehicle. The vehicle was leaking fuel from the high-pressure pipe leading to the fuel pump. The contact associated the failure with NHTSA Campaign Number: 18V907000 (Fuel System, Gasoline, Engine); however, VIN was not included in the recall. The dealer was contacted; however, the vehicle was not diagnosed or repaired because the VIN was not included in recall. The manufacturer was made aware of the failure but offered no assistance. The contact was referred to the NHTSA Hotline. The failure mileage was approximately 250,000.

On July 14, 2026, the vehicle's engine was replaced by an authorized dealership under an official Kia recall. On August 16, 2026, while driving on the highway, heavy smoke suddenly began emitting from the engine compartment. When attempting to slow down, the braking system suffered a total loss of power and failed completely. To stop the vehicle, it had to be steered into the highway median to intentionally scrape against it to force a stop. Immediately upon exiting the vehicle, heavy flames were observed under the engine compartment before completely engulfing the front of the car. The fire department extinguished the fire, and the vehicle is a total loss.

The contact owns a 2013 Kia Optima. The contact stated that while driving approximately 70 MPH with the cruise control activated, there was smoke coming from underneath the passenger’s side of the hood before the vehicle decelerated. The contact stated that moments later there were flames coming from the underneath the hood of the vehicle. The vehicle was parked on the side of the road and flames quickly engulfed the vehicle. The Fire Department was called to the scene and arrived and extinguished the fire. During the fire the vehicle was destroyed and was later towed to a nearby storage facility. While attempting to quickly exit the vehicle the contact fell to the ground and sustained an injured left leg and left side. The cause of the failure was not yet determined. The contact stated that the engine was recently installed related to a recall repair. No additional information was available. The manufacturer and local dealer were notified of the failure. The failure mileage was 140,000.

The contact owns a 2013 Kia Optima. The contact stated that while driving 30 MPH, the steering wheel was difficult to turn. There was an abnormal clicking sound coming from the vehicle and the vehicle was uncontrollable. The vehicle was towed to the local dealer, where it was diagnosed and determined that the coupling in the steering wheel needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and confirmed that there was no coverage under the warranty extension for the MDPS flexible coupling. The failure mileage was approximately 139,000.

I am writing to formally report a dangerous safety defect involving the braking system and the Hydraulic Electronic Control Unit (HECU) on my 2013 Kia Optima Hybrid. While operating the vehicle, severe warning lights illuminated on the dashboard indicating an immediate braking system and stability control failure. A diagnostic scan revealed active fault code C1237, pointing specifically to a primary pressure sensor signal failure embedded inside the internal HECU assembly.This issue presents a severe safety hazard. The failure compromises the vehicle's electronic brake assist, anti-lock braking system (ABS), and active stability systems. This results in unpredictable pedal feel and significantly increased stopping distances, drastically elevating the risk of a high-speed collision.Furthermore, this vehicle architecture relies heavily on clean voltage from the 12-volt battery system. Sudden drops in battery performance appear to trigger cascading communication faults within the HECU network, causing the vehicle to lose crucial safety systems without adequate warning.Kia is aware of severe electrical and internal component defects within the HECU modules of this generation, as evidenced by Safety Recall SC284 (NHTSA Campaign 23V652000) for HECU internal electrical shorts and engine fire risks. However, dealerships are treating related sensor failures inside the exact same HECU assembly (such as the internal primary pressure sensor) as customer-pay maintenance issues, rather than recognizing them as symptoms of a fundamentally defective or failing control unit. Dealership service centers are recommending piecemeal, expensive part replacements (like pedal travel sensors) that do not resolve the underlying safety risk of an internally failing HECU module.I request that the NHTSA investigate whether internal pressure sensor failures (Code C1237) and related electronic brake module collapses on 2011–2015 Kia Hybrid models are connected to the known sub-component defects wi

I own a 2013 Kia Optima and I am experiencing recurring fuel system-related symptoms. The fuel gauge fluctuates even when the vehicle has a full tank of fuel, causing an inaccurate fuel level reading. In addition, the vehicle has begun to hesitate during operation, which raises concern that there may be an underlying fuel delivery or fuel system issue. I previously experienced a similar issue years ago, and I believe the vehicle was repaired during a Kia recall or service campaign. The problem has now returned, and I am concerned that the previous repair may not have permanently corrected the issue or that there may be a related defect affecting other vehicles. The combination of an inaccurate fuel level reading and engine hesitation could create a safety concern because the driver may not know the true amount of fuel remaining and may experience unexpected loss of power while driving. I am requesting that this issue be investigated to determine whether it is related to a previous recall repair, a fuel system defect, or another safety-related condition affecting the 2013 Kia Optima.

Paint began chipping/flaking off little by little everytime I washed the car. It’s a common occurrence with snowy white Kia paint in this year

the engine revs high and transmission wont shift and when you turn the steering wheel ya get a loud click and the steering wheels jumps

The steering column From the car has diminished causing dangerous shaking on highway at high speeds

The contact owned a 2013 Kia Optima. The contact stated that while driving at an undisclosed speed on the main road of a T-intersection, the contact blacked out before another vehicle crashed into the front passenger's side of the vehicle. The contact stated that the front of the vehicle sustained severe damages, and there was more damage on the front passenger's side of the vehicle. The air bags deployed. The contact stated that the seat belt retracted excessively, causing the contact to be pinned in the seat and to sustain severe injuries. The contact was assisted out of the seat and was partially unconscious. The contact was unsure if any warning lights were illuminated after the crash. A Police report was filed. The ambulance transported the contact to the hospital. The contact sustained a fractured L2 and back, ruptured bowel, and intestines and internal bleeding in the stomach. The contact underwent surgery and physical therapy. The vehicle was towed and deemed totaled by the insurance company. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a related recall. A complaint was filed. The failure mileage was approximately 130,000.

Large delamination of paint on the vehicle.

The contact stated that while driving the vehicle began to unexpectedly slow and then stalled. The vehicle was unable to restart. No warning lights illuminated. The vehicle was taken to the dealer where it was not diagnosed or repaired. The manufacturer was notified of the issue. The approximate failure mileage 215,000.

I was driving on the high way and my car completely stopped I towed it to a shop and the engine seized

My 2013 Kia Optima was running fine at 65 mph when suddenly the engine stalled. I then coasted to the shoulder and smelled burning plastic. As soon as I opened the hood the engine started being consumed in fire, it quickly went to a very large engine fire that consumed the front half of the car. There were no other vehicles involved with this incident. Vehicle is a total loss.

The vehicle is experiencing sudden engine stalling while in motion, a known safety hazard. Despite a documented maintenance history with no issues, the dealer (Bayside Kia) is attempting to deny a Theta II Settlement claim by shifting the narrative to 'engine sludge,' which only appeared as a symptom in June 2025( Walmart oil change) alongside engine performance issues. The vehicle has active codes P0014 and P0017, which are secondary symptoms of the internal bearing wear and metallic debris contaminating the oiling system. KDS Diagnostic tests showed Cylinder 1 at 0.16mm (approaching the 0.20mm failure limit). This clearance proves the connecting rod bearings are worn and reaching the failure threshold; this mechanical wear is the root cause of the engine's inability to operate safely. The presence of metallic debris in the oil is the definitive signature of the Theta II manufacturing defect. Furthermore, the dealer acted in bad faith by attempting to charge for Airbag repairs (Codes B1346/B1481) that are covered under the 15-year Clock Spring Warranty Extension (CS1102). The dealer has dismissed my qualifying maintenance documents, claiming they are 'not official,' which is a direct violation of the Magnuson-Moss Warranty Act. A manufacturer cannot deny a warranty claim because services were performed at third-party facilities, nor can they deny a claim without proving 'exceptional neglect.' I am reporting a refusal to honor a court-ordered safety settlement and an attempt to return an unsafe, stalling vehicle to the road.There is no evidence of engine abandonment or exceptional neglect. I’m considered "in compliance" if I can show I didn't go more than 14 months without servicing or a certain mileage between oil changes.The dealer's dismissal of verified third-party receipts and bank statements is a bad-faith attempt to ignore an inherent manufacturing defect documented by a 0.16mm BCT result and metallic debris.

We were told by the mechanic that the engine was locked up after the car refused to drive faster than approximately 23 mph. We had to have the car towed from Boone, NC which was about 200 miles. The car is at our house and is available for inspection upon request. I have made repeated calls to different Kia dealers asking for a call back to assist me with direction but there will never be a returned phone call. As far as I know, there has been no inspection of the engine or vehicle.

The contact owns a 2013 Kia Optima. The contact stated that while driving at an undisclosed speed, the engine unexpectedly seized without warning. The contact stated that after the vehicle lost motive power, several unknown warning lights illuminated. The vehicle was restarted; however, the failure recurred. The vehicle was towed to an independent mechanic, where it was diagnosed that the engine had seized and needed to be replaced. The vehicle was not repaired. The vehicle was then towed to the dealer but was not diagnosed or repaired. The contact was informed that no diagnostic trouble codes were found. The manufacturer was made aware of the failure. The failure mileage was approximately 125,000.

Code : P1777 Transmission- oil pump A issue with the Valve cover gasket leaking into the engine causing a misfire. Making the car suddenly stop while driving which is very unsafe. I took the car to the dealership and they want to charge me for the repairs. I have 2 kia optima hybrid and both cars have the same issue around the same mileage. There were no warning lights during the time it was at the shop. I believe later down the line the engine will stall out and it should be fixed now while under warranty. However I received no help from the dealership unless I am willing to pay upfront. In addition to this there are electrical issues the front seats aren't moving immediately when the button is pressed. The steering wheel buttons barely work along with the radio. This is a huge problem that needs to be fixed.

The contact owns a 2013 Kia Optima. The contact stated while driving 75 MPH, the vehicle went into LIMP Mode and failed to exceed 60 MPH. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the knock sensor and the harness had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred on several occasions, and the vehicle was driven or towed to the dealer as needed. The dealer cleared the diagnostic trouble codes and informed the contact that a recall repair would not be completed unless the engine made loud knocking sounds or seized. The contact stated that while driving at an undisclosed speed, the engine made an abnormally loud sound and seized. The vehicle was towed to the residence. The vehicle was then towed to the dealer, where the contact was informed that the engine was not eligible for replacement due to a lack of maintenance records because the contact did not have all the oil change service records available. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 297,000.

While driving my KIA Optima on the interstate the rear subframe suffered catastrophic structural failure, resulting in the steering wheel going out of alignment, the rear passenger side wheel tilting with the bottom of the tire being far out compared to the top. This resulted in the rear of the vehicle swaying side to side and being difficult to maintain in a straight path. This vehicle was previously serviced under KIA Campaign SC141 (internal subframe corrosion) at Griffin KIA on April 27, 2017. Despite this safety remedy being performed the subframe rotted through and snapped. This is a remedy failure. The anti-corrosion was applied by the manufacturer failed to prevent the exact structural failure it was designed to mitigate. I have physical evidence (Repair Order #92144) proving the remedy was performed and photographic/video evidence of the subsequent structural break. The manufacturer (KIA) has denied assistance, claiming the failure is "unrelated" to the corrosion campaign despite the part being the exact component covered by the campaign." SC141 involved the inject of wax into the metal components of the subframe of the vehicle and was KIA's response to the NHSTA's concerns about the metal components of their vehicles being unable to withstand salt in the Rust Belt states. The campaign only was for the vehicles in the rust belt states. KIA was very aware this was a safety issue and attempted to avoid a recall by issuing this campaign. The campaign failed and as a result my life was put at risk. I asked KIA for a good will repair of the rusted subframe but they refuse indicating the believe the part that clearly broke due to rust is unrelated to the safety campaign. Several of their employees stated it was very clear the part broke due to rust with one indicating he had a list of rusted parts needing replaced. I'd like the NHTSA to review this failed campaign and ensure the safety of all vehicles relying on this failed safety measure.

Clanking noise is steering column and very loose steering.

The contact owns a 2013 Kia Optima. The contact stated that while driving approximately 35-40 MPH, the vehicle started shuddering with a knocking sound coming from the engine. The check engine warning light was illuminated. The vehicle was taken to the local dealer, and the dealer declined to repair the vehicle under NHTSA Campaign Number: 17V224000 (Engine and Engine Cooling). The dealer stated that the vehicle had a branded title. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 163,814.

I took the Kia to Hurst Dealership and Scott told me he would check it out. He called me and told me I needed the key replaced, so we paid them 230 dollars. Then he told me he found 4 recalls, fixed 3 of the 4 recalls. The last one, the engine seizing up, was still not complete. after 30 days we removed the car from that dealership because the whole time they were trying to sell us a car. Now the car doesnt even start, there is no key, there is lots of damage to the front end and underneath the engine is missing covers and who knows what else. Worst employees do the things the company itself tries to prevent, Scott is perfect for ruining reputations of the employers he (works for)

The contact owns a 2013 Kia Optima. The contact stated that while approaching a freeway and attempting to merge, the vehicle suddenly stalled. There was no warning light illuminated. The vehicle was towed to the local dealer, where it was diagnosed, and it was determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and opened a case, but no assistance was provided. The failure mileage was approximately 69,000.

Brake pedal loses pressure and disengages with brakes. Traction light, maintenance light, hybrid system warning message, check brakes message and parking brake intermittently turns on and off. I called Kirby Kia of Ventura a few weeks ago and let them know about my issue with the car. I explained that I took the car to a mechanic and the diagnostic they did stated the issue with the car could be because of one of the recalls. On 4/10/26 I took my vehicle to Kirby Kia of Ventura for the recalls and asked if they could do the diagnostic. Raul from Kia was the service rep that spoke with me. He stated they would do the recalls and then, if needed, they would perform the diagnostic. Later that day Raul called me and stated the recalls were completed and no issues were found. Several items were found from Kia's point inspection, but none related to the issue at hand. I then asked Raul if they could perform the diagnostic to know what was wrong with my car and he stated that they could do the diagnostic on Monday, 4/13/26. Raul stated he would give me a call around 10 to 11 am, to discuss any issues. Raul called at 10:49 am, and stated no lights on the dashboard have come on and he didn't want to do the diagnostic because the lights weren't on. Kirby Kia of Ventura service department are crooks and only want to assist you if they get money out of you. My car still has the same issue, possibly damage to the HECU from the recall, but Kirby Kia didn't want to run the diagnostic on my car to find out if it was damaged. Kirby Kia of Ventura is a horrible organization and I will never purchase another Kia vehicle for this reason.

The contact owned a 2013 Kia Optima. The contact stated that while driving at an undisclosed speed, the front end of the vehicle caught fire.

The contact owns a 2013 Kia Optima. The contact stated that while attempting to start the vehicle, the vehicle failed to start. There was no warning light illuminated. The vehicle was towed to a local dealer, where it was diagnosed and it was determined that the turbocharger had failed, and the engine and turbocharger needed to be replaced. The vehicle was not repaired. The contact received a letter from the dealer that the vehicle was covered under a manufacturer settlement for engine replacement; however, the dealer advised the contact that there was an out-of-pocket cost to replace the turbocharger. The manufacturer was informed of the failure. The failure mileage was unknown.

The contact owns a 2013 Kia Optima. The contact stated that while his son was driving approximately 35 MPH, there was an abnormal metal-on-metal sound coming from the vehicle, and the vehicle stalled. The contact drove out to the location and became aware that the oil and the battery warning lights were illuminated. The contact attempted to restart the vehicle, but the vehicle failed to restart, and the starter motor was smoking. The contact stated that prior to the engine failure, the starter motor had been replaced. The vehicle was towed to the independent mechanic who had recently replaced the starter motor. The mechanic diagnosed the vehicle and informed the contact that the engine had seized and needed to be replaced. The mechanic informed the contact that the VIN was included in NHTSA Campaign Number: 17V224000 (Engine and Engine Cooling). The contact called the local dealer and the manufacturer but was informed that the vehicle would not be repaired. The failure mileage was approximately 130,000.

The contact owned a 2013 Kia Optima. The contact stated that while driving at an undisclosed speed, the front of the vehicle started excessively smoking and caught fire. No warning lights illuminated. The fire was extinguished by the local fire department, and a fire report was filed. A police report was not filed. The contact received notification of NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic). The dealer was not contacted. The vehicle was not diagnosed or repaired. The vehicle was destroyed. The manufacturer was made aware of the failure via customer care support since no representative was reached via the phone line. The approximate failure mileage was 179,000.

The contact owns a 2013 Kia Optima. The contact stated that while a family member was driving the vehicle at 40 MPH, the vehicle stalled. There was no warning light illuminated. The driver pulled over to the side of the road where the vehicle failed to restart. The vehicle was towed to the residence, where an independent mechanic diagnosed the vehicle and determined that the engine and transmission needed to be replaced. The vehicle was not repaired due to the cost. The dealer and the manufacturer were not contacted or notified of the failure. The failure mileage was unknown.

My car started shutting down while driving. After the engine started seizing the key wouldn't turn in my ignition. Took car to dealership immediately on 10, 2026. Took again in 2024 for recall and other repairs. Found out after requesting previous service incidents they failed to do recall repairs and never notified me of it, or to come back. I've requested current diagnostic report several times in writing and verbally with codes for this current service, with non compliance. My car is still at the dealership needing work and I need current diagnostic report before I pay for repairs. I am attaching a dealership diagnostic e-Report for my 2013 Kia Optima from 2024. While the report lists “No Current DTC” for several systems, it also documents multiple “Communication Fail” errors across critical modules, including Smart Key, Head Lamp, Air Conditioner, Brake, and other systems. These communication failures indicate a broader electrical or network issue within the vehicle, not simply a failed battery. The report also shows that certain diagnostic scans were not properly performed. Additionally, there are historical fault codes related to TPMS and weight classification systems, further supporting that the vehicle has experienced ongoing electrical issues. Despite these findings, the dealership attributed the vehicle failure solely to a bad battery and did not provide a current battery diagnostic test. They also failed to address an open recall related to electrical/fuse issues prior to this failure. Based on this past diagnostic report, I believe the root cause of my vehicle’s failure is an unresolved electrical defect, potentially related to the outstanding recall, rather than normal battery wear. This has resulted in my vehicle becoming inoperable and poses a serious safety concern.

1) Motor failed on interstate and car towed to automotive shop. Currently still at the shop with hope to tow to Kia to address issue. 2)My teenage daughter and her friend were placed in a dangerous and potentially life-threatening situation due to what appears to be a catostrophic vehicle failure. While driving our 2013 Kia Optima whith approximately 160,000 miles, the vehicle suddenly lost power while our daughter was traveling a major highway. The car quit responding to the gas pedal and she was forced to pull over on the side of the highway and was stranded in traffic with no safe way to move the vehicle. When she attempted to restart the car the engine light began flashing (it did not do so before hand), the car was shaking and undriveable. This was not a minor inconvenience, it was a serious safety hazard. A young driver was left sitting on the shoulder of a high-speed roadway with cars and trucks passing at highway speeds up to 80 mph. Had another driver drifted or had she not been able to reach the shoulder in time, this situation could have easily resulted in a major crash or fatality(-ies). The vehicle would not restart properly and had to be towed. Prior to this incident, there were no obvious warning sings of an imminent catastrophic failure. The mechanic's invoice of his diagnostics is attached. Vehicles should not fail in a way that suddenly leaves drivers stranded in active highway traffic with no warning. This type of failure creates an extremely dangerous situation not just for the driver but for everyone on the road. I strongly urge the NHTSA to review whether this model vehicle has known engine or safety defects that can lead to sudden engine failure or loss of power while driving. No parent should have to get a phone call that their child is stranded on the side of a major highway because their car suddenly died without warning. I am requesting this vehicle incident be documented and investigared as a potential safety defect.

Vehicle: 2013 Kia Optima SXL VIN: [XXX] While driving on a highway at approximately 55–58 mph, the rear driver-side electronic parking brake (EPB) motor housing failed with a loud bang. Immediately after, there was heavy smoke and a strong burning smell. The vehicle became very difficult to drive, and the wheel began screeching and dragging as if the brake had locked. The failure appears to have caused the rear brake caliper to seize while the vehicle was in motion. This created a dangerous driving situation at highway speed and could have caused a crash. The brake system component that failed appears to be the electronic parking brake actuator/motor assembly attached to the rear caliper. This was a sudden mechanical failure, not normal brake wear, and it occurred while driving at speed. Kia care case number: XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
