Fuel injectors become unseated randomly causing gas to be sprayed inside engine compartment. Issue can be seen upon request. This issue could cause a fire/explosion as fuel sprays out. The issue was repaired once by an Independent shop, then the issue reoccurred and has now reoccurred again. The issue fails randomly and fully with the symptom being the vehicle not wanting to start.
NHTSA complaint #11754172 — an unverified report by a vehicle owner.
The vehicle intermittently fails to start in two different situations. First, when the auto Stop/start system shuts the engine off while the vehicle is stopped anywhere, the engine sometimes refuses to restart, leaving the vehicle immobilized. Second, there are occasions when I park the vehicle, turn it off normally, and upon returning, the engine will refuse to start.

"The vehicle has twice suffered a sudden, catastrophic loss of motive power at highway speeds (approx. 70 MPH) on the interstate, forcing the driver to coast across active traffic to the shoulder without engine pull. The engine revs freely in 'Drive' but the transmission fails to engage any gears. No dashboard warning lights, check engine lights, or diagnostic trouble codes are triggered during or after the failure. The failure resets temporarily only after cycling the ignition key off and on.The vehicle previously had Safety Recall SC250 (8-speed Electric Oil Pump) performed by an authorized dealer, but the software flash completely failed to prevent this catastrophic hydraulic/electronic failure mode or provide the federally mandated dashboard warning countdown. The vehicle is entirely unsafe to drive,

NHTSA complaint #11751993 — an unverified report by a vehicle owner.
I am filing this complaint regarding my 2021 Kia Sorento, which has suffered a serious transmission failure. The vehicle is displaying diagnostic code P0741, indicating a torque converter clutch malfunction. The transmission slips, shifts harshly, hesitates during acceleration, loses power unexpectedly, and has become unsafe to drive. The vehicle is available for inspection upon request.This defect has put my safety and the safety of others at risk. On several occasions the vehicle failed to respond properly when accelerating, including while entering highways and driving in traffic. The hesitation and sudden loss of power created fear and anxiety because I could not trust the vehicle to move when needed to avoid a dangerous situation. The problem has been reproduced and confirmed by a repair facility, and the symptoms are consistent with a transmission torque converter clutch failure. I also contacted Kia and provided the vehicle information. Kia informed me that they would not repair the vehicle because it has exceeded 100,000 miles and that the recall or warranty extension had expired. However, my vehicle is experiencing the same transmission-related symptoms reported by many other Kia owners.I never received any recall notification because I purchased the vehicle from a dealership as the second owner. Had I been properly notified, I would have taken the vehicle in for inspection much earlier. It is extremely frustrating and financially devastating to be denied assistance solely because of mileage when the failure appears to be related to a known transmission defect.Before the failure, the check engine light illuminated and code P0741 appeared. Prior to that warning, the vehicle had already shown delayed shifting, slipping, hesitation, rough gear changes, and loss of power, which became progressively worse.This situation has caused significant emotional stress, anxiety, and financial hardship. I am requesting a full investigation and a fair resolution from kia.

I took my 2016 Kia Sorento to the dealership for an emissions service update as a result of a service bulliten (SC340) After recieving the car back, the transmission acts unpredictably and the throttle is erratic. This happens when started cold and continues until the engine reaches temperature. It did not do this previous to the update. It is a safetey hazard and almost caused a collision. The throttle response was sluggish, it hunted for gears and as a result I was unable to safely merge into traffic endangering myself and other drivers.

(Transmission and motor) I had taken my car to the dealership on XXX for recalls and all the signal were fine before going there. They took my car back to do the recalls and my son and I waited . Once they were done we left closer to closing time is noticed there was a burn mark on my dash board that wasn’t there before the recalls. Going forward on the way home. We were waved down by a man stating that my signal and brake light weren’t working . So that next day we took my car back to the dealership to see what happen, why all the sudden different alerts were coming up. They had the same mechanic relook at the car and a when finish 31/2 hour latter was told I needed a new transmission, costing $7384.94 which I don’t have . They charge me $179.00 just to confirm what they said about needing a new transmission. I was devastated and confused why I wasn’t told that the day before. So a few days later I took it to another machanic to see if the could see why the lights weren’t working and he ended up putting new bulbs in and got them working but also he put it in a diagnosis machine 2 of them and couldn’t get a reading at all and said I should take it back to find out why he couldn’t get a reading. I was so frustrated at that point I just was upset! I then had a friend of the family mechanic look at it and he said it wasn’t the transmission it was a knock sensor that I needed so I ordered it. When I called him to install the knock sensor he was too busy to do it and it had already been a whole month of waiting so I reached out to a place in Cumberland RI to see if he could install the knock sensor had it towed there and he kept it for three days and said it was a transmission computer and he tried two of them and neither of them worked and charged me $150 for that I was humiliated and crying , I went there to have my car towed home seen him while waiting for the tow truck to come he said I needed a new transmission and now a motor, crying again.

Hello. I just started smelling gas fumes when my car has been running. I see no drips , etc. It happens everytime I drive it to the point where someone pointed it out to me. I had a new engine put in by KIA for my old engine "going to sleep" about 4 years ago. I have been told that this is a on going problem with the Model I have. I want to know what I should do at this point. Im [XXX] and [XXX] so I dont have the money to take it all over the place if this engine issue is covered. Could you please let me know and how to proceed? [XXX] [XXX] Cell [XXX] THANK YOU FOR ANY HELP ps....You should have record of KIA replacing the engine on file??? Is this a warranty issue since I do have a newer engine? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11747800 — an unverified report by a vehicle owner.
To Whom It May Concern, I am writing to formally dispute a repair charge and report unacceptable service at Courtesy Kia (Mesa, AZ) regarding my vehicle. Timeline of Events: June 12, 2026: I brought my vehicle to Courtesy Kia for a mandatory software recall. Prior to this appointment, my fuel gauge worked perfectly. Immediately upon picking up the vehicle, the fuel gauge ceased to function. After calling customer service, I brought the vehicle back for inspection. The dealership kept my car for three days. Despite the issue being caused during their previous service, I was denied a loaner vehicle, forcing to come to take the car and use it during the weekend or I can wait until Monday 29 until the service manager back but I asked them I can’t use the car with this error as it’s not safe for me and my kids and that should be fixed by them since that’s their mistake and unfortunately I’ve had paid out-of-pocket for my family's transportation. June 26, 2026 (Diagnostic): The service department initially claimed the issue was a broken fuel pump and quoted me $1,210. I informed them this was impossible, as the fuel pump was completely replaced just 3 months ago. I requested to speak to the service manager, but was told he was unavailable until Monday. And the gentleman Michael who was taking care of my car said let me speak with the technician and back to me again with different quote The diagnosis was suddenly changed to a "fuel sending unit and gasket," with a new quote of $546?? But if I want I can wait until Monday to check with service manager. June 29, 2026: After receiving no follow-up call, I contacted the dealership myself. I spoke with Service Manager Shane Hackelton, who refused to take responsibility for the damage caused during the recall service and insisting that not related to recall software and should be fixed by myself. I look forward to your prompt response and a resolution to this matter.
NHTSA complaint #11747304 — an unverified report by a vehicle owner.
On June 6, 2026, while driving home, the vehicle suddenly began smelling strongly of gasoline and burnt rubber. Within seconds, thick black smoke became visible in the side mirrors, followed immediately by white smoke pouring from the front hood and into the passenger cabin through the air vents. As I attempted to pull over to safety, the vehicle completely stopped responding. The brakes failed to operate, the engine stalled, and the steering wheel locked completely. We were barely able to bring the vehicle to a stop. Immediately upon exiting, visible flames erupted from underneath the driver's side of the vehicle and out of the front hood. The engine compartment and motor burnt completely.The safety of the driver and front passenger was put at extreme risk of death or severe injury. Because the brakes and steering locked up simultaneously while the cabin filled with smoke, we almost lost the ability to safely exit a moving vehicle that was actively catching fire. Furthermore, at no moment prior to or during the failure did any warning lamps, check engine lights, or diagnostic messages illuminate on the dashboard. There was absolutely zero advance warning from the vehicle's safety systems.The fire originated from a catastrophic fuel system failure, specifically matching the known issues of the high-pressure fuel pump leak.The vehicle is a total loss and is currently located at a tow yard. It is fully available for inspection upon request.Local police responded to the scene and generated an incident log number. A corporate claim has been opened directly with KIA but as of today, no inspector from the manufacturer or insurance has been sent out.
NHTSA complaint #11744052 — an unverified report by a vehicle owner.
I am filing a safety complaint regarding a Kia vehicle I purchased from CarMax Waldorf approximately 3 months ago. The vehicle has developed a strong gasoline/fuel odor that is consistent with a possible fuel leak. This creates a serious safety concern, including the risk of fire or explosion while driving or operating the vehicle. The issue began shortly after purchase and has continued. The vehicle is now unsafe to drive due to the strong fuel smell. When I contacted CarMax about the issue, I was instructed to take the vehicle to a Kia dealership instead of CarMax inspecting or addressing the safety concern themselves. I believe this is improper handling of a potentially dangerous defect in a recently sold vehicle. At this time: * Vehicle emits strong fuel/gas smell * Safety risk increases while driving * Vehicle has been in my possession for only 3 months * Issue appears to be early or pre-existing defect * I was redirected away from CarMax responsibility I am requesting that this safety issue be investigated as a potential fuel system defect and documented appropriately.

My high pressure fuel pump is spraying fuel in my engine. This is a new engine replacement as of October 2024. This is a huge fire risk and we cannot operate this vehicle.
NHTSA complaint #11742574 — an unverified report by a vehicle owner.
The contact owned a 2017 Kia Sorento. The contact stated that while driving at an undisclosed speed, the contact noticed an abnormal fuel odor, and there was white smoke coming from underneath the hood. The contact was able to safely pull into a driveway, and the contact noticed flames coming out of the hood. The contact stated that the fire caused property damage to the driveway, including debris and burn marks. The entire vehicle was engulfed in fire and deemed destroyed. The fire department extinguished the fire. A fire department incident report was filed. The police arrived at the scene, assisted in directing traffic, but did not file a report. The contact further stated that while attempting to exit the vehicle, the contact's mother fell on the ground. No medical treatment was sought, and no injuries directly related to the vehicle fire were reported. The manufacturer was notified of the failure. The approximate failure mileage was 150,000.
NHTSA complaint #11742388 — an unverified report by a vehicle owner.
The vehicle suffered a sudden, severe engine malfunction/misfire while in operation, presenting a serious safety hazard on the road. Following the incident, the vehicle was taken to an authorized dealership service center (Repair Order #XXX), where technicians verbally confirmed that the engine requires a complete replacement due to internal mechanical failure. The catastrophic mechanical failure of the engine directly caused consequential damage to the emissions system, entirely clogging the catalytic converter with unburned fuel/debris. Despite the clear link to the known, systemic defects inherent to the Theta II engine line—which is subject to active federal consent orders, safety recalls, and lifetime warranty extensions—both the dealership and Kia Corporate are refusing to honor the 8-year/80,000-mile Federal Emissions Defect Warranty. The manufacturer is attempting to use the catastrophic failure of their own defective, recalled engine line to evade their legal environmental and safety warranty obligations, leaving the consumer stranded without alternative transportation. This represents a systemic effort by the manufacturer to deflect liability for documented powertrain safety failures onto individual consumers.

Car completely stalled while on the freeway with no warning, no engine lights, nothing….luckily we were going downhill and were able to pull over to the side safely. Still owe 6k to the finance company but mechanic claimed I needed a new waterpump…after being changed and charged the car still wouldn’t turn on despite the new waterpump….and a bunch of new obd codes showed up & now I need a new engine. After a lot of research I’ve learned this car is notoriously known for many recalls and overall complains…..I wish I had done research before buying it, now I’m in debt for a car I can’t even drive
NHTSA complaint #11741029 — an unverified report by a vehicle owner.
VEHICLE: 2023 Kia Sorento, VIN [XXX] , currently 48,000 miles. Vehicle has never been in a collision. DEFECT: FUEL FILLER DOOR ACTUATOR WITH NO EMERGENCY RELEASE — STRANDING HAZARD The fuel filler door actuator fails to release on demand intermittently. When the actuator fails, the door must be pried open with tools or force, which is inconsistent and not always possible. The dealership service advisor has stated that this model is not equipped with any emergency release mechanism for the fuel filler door. With no emergency release, the actuator is the only mechanism by which the fuel door can be opened. SAFETY IMPLICATION: An intermittent actuator failure with no backup release mechanism creates a stranding hazard. If the actuator fails when the vehicle is low on fuel — particularly in remote areas, in cold weather, at night, or in emergency situations requiring refueling to reach safety or medical care — the vehicle cannot be refueled and becomes immobilized. This is a single-point-of-failure design on a system required for vehicle operation. The condition has been reported to the dealership and remains unresolved. The vehicle remains within the 5-year / 60,000-mile basic warranty period. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11740591 — an unverified report by a vehicle owner.
Faulty fuel injectors are causing consistent engine misfires and occasionally causing the check engine light to illuminate and for the vehicle to reduce power greatly. This poses a great safety risk to both myself and other drivers on the road because in the event of a large misfire, my vehicle suddenly slows and I have to navigate to the shoulder of the road. A Kia dealership has confirmed that the cause of these misfires is due to a faulty fuel injector that begins to work inconsistently above 3000 RPM. This issue began shortly after the vehicle was purchased in 2023, but due to the dealerships inability to replicate the issue it went without correction. In the recent year, this issue has increased greatly and it is now a consistent issue and this is why it was able to be diagnosed now. This is a very common and widespread issue amongst other individual with vehicles with the same engine.
NHTSA complaint #11740305 — an unverified report by a vehicle owner.
The vehicle involved is a 2019 Kia Sorento with approximately 111,000 miles. Over the course of ownership, the vehicle has experienced numerous unresolved mechanical and safety-related issues, including ongoing fuel leak concerns, excessive oil consumption/loss of oil, rough shifting, shift solenoid problems, rattling noises, shaking/vibration while driving, and repeated drivability issues. The primary safety concern at this time is a suspected fuel leak that multiple independent mechanics have identified. I have been told by at least three separate mechanics that the vehicle appears to have a fuel leak. During my most recent oil change at Valvoline, the technician expressed concern about the safety of driving the vehicle in this condition and warned me that driving a vehicle with a fuel leak could be dangerous. I previously brought the vehicle to Kia dealerships multiple times while the extended warranty was active and specifically requested inspection for the suspected fuel leak. On at least three separate visits, I was informed by the dealership that they could not find or confirm a leak. Because the issue was never resolved or properly diagnosed while under warranty, I am now out of warranty coverage and facing potentially dangerous and costly repairs. This issue has placed my safety and the safety of others at risk due to fear of possible fire hazards, stalling, or sudden vehicle failure while driving. Because of these concerns, I have significantly reduced driving the vehicle and currently do not feel safe operating it regularly. This has created substantial hardship because this is my only vehicle for work and daily life. Additional unresolved issues with the vehicle include: - Persistent rough shifting and shifting hesitation - Shift solenoid issues - Ongoing excessive oil consumption/loss of oil with no confirmed source - Constant rattling noises - Excessive vibration/shaking while driving - AC system failure around 60,000 miles - Electrical seat failur
