The engine failed and is now inoperable. The vehicle has been consuming excessive oil since I purchased it in 2022. I have all oil change records and top offs documented. In may 2026 the engine had a total failure, was making excessive noise, was shuddering and vibrating, blowing lots of smoke from the exhaust and then would not start. The check engine light came on. I towed it to roseville kia for diagnosis. Kia refused to honor the lifetime warranty under the class action lawsuit, claiming the engineer failure was due to a damaged exhaust valve. The did not complete the diagnosis. They did not follow the NHTSA engine replacement flowchart past flowchart a because code p1326 was not present. However the flowchart specifies engine noise and failure to turn over qualify the technician to perform flowcharts b and c. Kia is refusing to complete the diagnosis and evaluate the rod bearings for damage, which would likely qualify the engine for replacement under warranty.

On Jan 1,2019 under kia pi-1803 recall I had a knock sensor detection system(ksds) installed on my 2013 kia Sorento. My car broke down and was towed into the kia dealership and it indicated a p1326 fault active . It was reset and released to me on 05/12/2026 after conducting a bct test saying it indicated pass drove it off the lot went 5 miles, and it broke down, towed back in and they replaced the ksds. They performed a bct replaced the ksds and then said it passed. I have requested an actual copy of the test not just a p. They have refused both at the dealership level and kia customer service . The results of both tests are conducted by techline and that information is available. I believe the vehicle is unsafe to drive as this has happened twice in a 2 day period . I do not trust that it passed the rod bearing tests without the actual test results.

Had to replace transmission at 133k miles. It was jolting sometimes providing a hard jolt at times will driving. There are also times of what feels like a cylinder misfire. Oil is constantly leaking and have to replace oil every 1k miles. Have had multiple shops look at it and not able to find anything. Now during acceleration there is a huge grey smoke cloud coming from the exhaust. Looking at this site and through online it seems to be a common issue with this car and engine. So there has been multiple issues with this car - oil consumption of the engine leading to smoke in the exhaust and the transmission which was replaced a week ago.

While driving on the highway on mother’s day weekend with my wife and daughter, the vehicle suddenly lost acceleration and engine power while traveling on a 5-lane beltway. The vehicle would not accelerate and I was unable to maintain normal highway speed. I had to coast to the side of the road with the hazard lights activated because of the safety risk. The vehicle was eventually restarted after being towed to a dealership, but it continued to have severe loss of power and could not safely travel above approximately 45 mph. The suspected failure involves the engine and emissions system. The vehicle has a history of engine-related issues and previously received engine-related repairs. The current engine has developed excessive oil consumption. This condition has resulted in fouled spark plugs and a catalytic converter becoming severely restricted/clogged from oil contamination, causing significant loss of engine performance. A dealership inspected the vehicle and documented the oil-burning complaint and catalytic converter-related fault. The dealership performed diagnostic work, including spark plug replacement, but the problem continued. An independent repair facility also inspected the vehicle and confirmed excessive oil consumption and catalytic converter restriction. The vehicle remains available for inspection. This condition presents a safety concern because the vehicle experienced a sudden loss of power while traveling at highway speeds and was unable to maintain normal traffic speed.

I am submitting this complaint regarding a 2019 kia Sorento that has experienced recurring oil loss/oil starvation and engine-related issues that I believe may present a safety concern. I purchased the vehicle used with approximately 45,000 miles. Since ownership, the vehicle has experienced repeated incidents involving low or nearly empty oil levels despite regular maintenance and monitoring. The vehicle previously underwent an oil consumption evaluation, however the issue continued afterward. During one event, the vehicle was reportedly found approximately three quarts low on oil. More recently, the vehicle again appeared to have little to no oil visible on the dipstick and began exhibiting drivability and engine concerns including grinding/banging noise during acceleration, intermittent timing/tensioner-type noise, misfires on cylinders 1 and 2, exhaust smoke, and strong oil-burning odor from the exhaust. Due to concern over possible engine damage and reliability, the vehicle was returned to the dealership for further diagnosis and repair. The dealership replaced ignition coils and spark plugs and road tested the vehicle extensively. While the vehicle is currently operating, I remain concerned that the underlying oil consumption/oil starvation condition may not have been permanently resolved. My concern is that repeated oil starvation conditions could potentially lead to sudden engine failure, loss of power while driving, or other safety-related issues. I am requesting that this issue be reviewed to determine whether similar complaints or defects exist involving oil consumption, oil starvation, or related engine failures in this vehicle.

The car started sticking when driving then a knocking in the engine. Upon investigation/ diagnostics we found that the engine is blown and needs replacing. I have owned this car for 3 years to date and have keep up on all maintenance which you can find on carfax there is no reason at 136,000 an engine should blow. I would like this fixed ASAP.

The contact owned a 2012 kia Sorento. The contact’s spouse stated that while driving at an undisclosed speed, the vehicle suddenly lost motive power with no warning lights illuminated. The contact's spouse noticed smoke coming from the front of the vehicle, prompting the contact’s spouse to pull over to the side of the roadway. Moments later, the front of the vehicle caught fire. The local fire department responded to the scene and extinguished the fire; however, the cause of the fire had not yet been determined. The vehicle was completely consumed by the fire and deemed destroyed. No police report was filed, the manufacturer was not notified of the failure. The contact’s spouse stated that the incident was extremely traumatic and believed the vehicle posed a serious safety hazard. The failure mileage was not available.

I recently took my 2016 kia Sorento l to the kia dealership for the emissions update recall. The next day when I started it up and put it in drive, it started jerking hard when I was trying to speed up (going from first to second gear). I had to stop and then slowly push the gas so it wouldn't jerk so hard, then it finally switched gears and was smooth. Ever since it's happening only at the first cold start up of the day, and have sluggish acceleration throughtout the day. No lights on or codes. I took back to dealership twice and they said they couldn't replicate it and so they aren't sure, but it definitely still does it (anyone riding with me notices before I even mention it).

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.

Vehicle has a recurring p0018 fault code (crankshaft position - camshaft position correlation bank 2 sensor a). Dealer diagnosed loose cam pins on bank 2 requiring major engine repair. This fault creates a safety risk as improper camshaft timing can cause unexpected engine stalling while driving, resulting in sudden loss of power, power steering, and brake assist. The manufacturer has denied warranty coverage despite the vehicle being within the 10-year/100,000-mile powertrain warranty. This appears to be a known widespread issue on the 3. 3l v6 engine. Vehicle has 96,000 miles and is still within warranty coverage period.

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.

At 116 miles, the engine blew and I was informed it would need to be replaced. I purchased a used engine from the same year of vehicle because kia said it would not be covered since the vehicle had passed the 100,000 mile mark. I spend over $5,000 to get this engine and have it installed by a licensed mechanic. This second engine has now also blown leaving me without a vehicle as a single mom with a child who has a medical disability. Kia does not have a recall on this engine, which is clearly faulty. There is no way for me to come up with the funds to replace this engine for a second time and is something that should not even have to have to be figured out. I have been in touch with multiple mechanics who say the only way to repair is to replace as it would cost way more to try to rebuild. Kia should stand behind this as they know it is an issue.

2018 kia Sorento, under 88,000 miles, with theta ii engine defect. Ksds update installed. Oil consumption issues requiring adding at least one liter of oil every 1,000 miles in between regular oil changes/ maintenance. Oil warning lamp does not illuminate at all or only blinks on for a second then stays off, even when oil is less than 1 liter. Noticed slight jerking/hesitation at acceleration for a few days, then experienced shaking and heard vibrations when breaking and idling. Within a few minutes, mil appeared with audible warning, "take this vehicle to a kia dealership. " immediately parked car. Towed to kia dealership. No record of dtc p1326 found, which would have qualified vehicle for new engine under pi1802 y/z theta ii extended warranty. Diagnostic found misfiring cylinder and fouled spark plug. Technician in the video stated "oil consumption. " due to absence of p1326 code, service manager suggests we replace fouled plug and return with the vehicle when the same issue happens again. This does not follow kia's own guidelines in pi1802 y/z campaign for a couple of reasons. First, activation of the mil in conjunction with the audio warning indicates the knock sensor p1326 code should have been generated and stored, but the warning system must have malfunctioned. Service dept. Did not to inspect the knock sensor harness for damage or oil saturation which could have kept the code from registering. Second, service dept. Did not consider shaking and vibration as "engine noise," which would have required them to perform a bct or test for connecting rod bearing noise, providing a pathway to request techline pwa approve replacing the engine under warranty. Kia's product improvement campaign for theta ii engines ought to prevent injury or death resulting from catastrophic engine failure. My vehicle presents clear evidence of engine failure progression at different stages. Rather than navigate the warranty via a techline, kia has advised me to continue driving.

Engine failure & excessive oil consumption causing the vehicle to overheat. Coolant low, suspect coolant loss internally in engine. P0524 engine pressure too low. Potential causes: low oil pressure, low oil level, wrong oil viscosity, contaminated oil, faulty oil pressure sensor, signal shorted to ground in electrical circuit of sensor, worn internal engine components. Per testing- coolant low, suspect coolant loss internally in engine.

The contact owns a 2016 kia Sorento. The contact stated that while the vehicle was parked and running, the vehicle shuddered abnormally. The vehicle returned to normal operation after the contact added oil to the engine. The failure had occurred on several occasions. The vehicle was taken to an independent mechanic to be diagnosed; however, the independent mechanic informed the contact that the engine was operating as designed. No repairs were recommended by the mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 1,500.

The contact owns a 2019 kia Sorento. The contact stated while driving at an undisclosed speed, the low oil and the check engine warning lights were illuminated. The contact stated that a few days later, the contact noticed white smoke coming from the exhaust. The check engine warning light illuminated intermittently. The vehicle was taken to an independent mechanic where it was diagnosed with detached cylinder head bolts and a failed engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 186,016.

Immediately after a dealership-performed warranty repair, the vehicle experienced a severe safety?critical failure at highway speed. The vehicle began shaking violently, produced loud knocking and impact noises, and metal pieces fell from the underside. The failure occurred without warning and created an immediate loss of safe drivability. The dealership later documented that an engine mount (‘lower dog bone mount’) had not been torqued to specification, which allowed the engine to shift back and forth under load. This improper torque caused the violent shaking, metal impacts, and falling metal. The problem was confirmed by the dealership, but no corrective repair was performed. Only a single bolt was re?torqued, and no inspection was done to determine the extent of damage, the source of the falling metal, or the cause of the knocking. The vehicle was returned in an unsafe condition and has not been driven since. The vehicle had to be towed directly from the highway due to the severity of the failure, and it was delivered straight to the dealership because it was unsafe to operate. The vehicle remains available for inspection.

Vehicle: 2019 kia Sorento issue: engine failure / safety concern complaint: I am filing a complaint regarding a 2019 kia Sorento that experienced sudden engine failure after clear warning signs that created a serious safety concern. The vehicle began making a loud ticking/knocking noise that progressively worsened over time. While driving, the vehicle struggled to accelerate and lost power. The noise became louder when pressing the gas. Shortly after, the vehicle shut off completely and is now unable to start at all. This failure occurred without any warning lights appearing on the dashboard, including no check engine light, which prevented me from knowing the severity of the issue in advance. After contacting kia, I was informed that there were multiple recalls on the vehicle that were not completed. However, I was never notified of these recalls as the current owner. I was told that recall notifications were sent to the previous owner, and no effort was made to notify me directly. Kia has refused to assist with the engine failure, stating that recalls must be completed first. However, the vehicle is now completely inoperable and cannot be driven to complete recall repairs. Requiring a non-running vehicle to complete recall updates is unreasonable and places consumers at risk. This situation raises serious safety concerns because: the vehicle lost power while in operation, creating a dangerous driving condition there were no warning indicators prior to failure the engine failure appears consistent with known issues involving kia engines I am requesting that this matter be investigated, including kia’s handling of recall notifications and their refusal to assist with a known engine failure issue under these circumstances.

The clock spring needs fixed no features including the horn is working in my airbag light is staying on. Also I now have a loud knock in my motor I understand this should fall under the extended 15 yr 150k warranty; 2012 kia vehicles (specifically the Sorento) with v6 engines are covered under major safety recalls for engine failure and fire risks. The primary issue involves metal debris from manufacturing that can cause premature engine bearing wear, stalling, and fire. You should check your VIN on the NHTSA site or kia's recall page to confirm, as these recalls are still active.

The contact owned a 2013 kia Sorento. The contact stated that he had received a recall notice for NHTSA campaign number: 23v652000(service brakes, hydraulic). The contact then stated that soon after the recall was serviced, the vehicle would hesitate to start after multiple attempts without warning. The vehicle had been taken back to the dealer on multiple occasions due to failure; the dealer was unable to diagnose the failure, but stated that the failure was not related to the recall. The contact then stated that while driving at approximately 45 mph, a white-grayish smoke began to emit from the vehicle without warning. The smoke became heavier and quickly turned black as the contact pulled over and exited the vehicle. The vehicle quickly became engulfed in flames as the authorities were called to the scene. Both the police and the fire department arrived at the scene, and the fire department extinguished the fire. A police report was not filed, and no injuries were reported. The vehicle was towed to an independent mechanic, where it remained in their possession. The vehicle was destroyed as a result of the fire. Neither the manufacturer nor the dealer had yet been notified of the failure. The failure mileage was approximately 190,000.

I am submitting a formal safety complaint regarding my 2022 kia Sorento, which is experiencing a dangerous and recurring loss of engine power during acceleration. This issue presents a significant safety hazard, particularly during situations requiring immediate acceleration such as highway merging, crossing intersections, and passing traffic.

I bought this used with 113,000 miles on it. Within the first year, I had to fix ac,oil leak and alternator. I also had to replace the transmission which gave out completely. Then about 14 months into owning this vehicle, the engine light came on, and I suddenly could not maintain speed. I was lucky I was not on the main highway where I would have been hit from cars behind me. Kia refuses to fix/replace the engine because it is out of warranty. I believe this is too many things that have gone wrong to not be considered defective. I now have to cut my losses and get a different car.

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.

The contact owned a 2017 kia Sorento. The contact stated that while her husband was driving at an undisclosed speed, the vehicle hesitated to accelerate as needed. No warning light was illuminated. The contact's husband noticed a cloud of smoke in the rearview mirror, but the contact stated that the smoke was coming from the engine compartment. The contact's husband pulled over, and she, her husband, and daughter all exited the vehicle safely. Before the vehicle was engulfed in flames, the contact checked underneath the hood and discovered a piece of plastic on fire. The contact dialed 911, and police and firefighters arrived on the scene. The firefighters extinguished the fire. The contact was unaware whether a police or fire department report had been filed. The vehicle was towed to a tow yard, and the insurance company was made aware of the fire. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 117,000.

My 2019 Sorento 3. 3l suffered high oil consumption followed by a severe oil leak at the back of the head/engine block threads. There is an odor of coolant which smells sweet with no visible coolant leak meaning there is likely coolant seeping into the engine mixing with the oil. I believe this an ongoing engine failure caused from kia not correcting the issues over many years.

Our 2021 kia Sorento has been to elmhurst kia service numerous times . The chief complaint is the kia sorrento keeps losing power while in drive reverse middle traffic even on the highway but yeah every time we take it in, they say either it’s the battery . You can’t use it in the eco mode . Turn off the shut off while in drive mode when at stops ! always a different excuse, but yet no recall and it’s not showing up on their computer, but yeah it’s happening and kia does not want to take ownership. The vehicle has been left there for numerous weeks at a time leaving us without a vehicle no loaner . But because cannot duplicate issue release vehicle back with no repairs or maintenance. Kia prefer you taking the car getting into a car accident before they decide to do anything or even a lawsuit because not enough people having same issue with the 2021 kia Sorento s model ! if you also have these issues please report them here so they can be forced to open a recall !!! before someone gets seriously hurt my Sorento has loss power on highway and in the middle of train tracks with my little ones in Sorento and we drove the vehicle from day one original owners not a used Sorento.

Timeline of maintenance & failure: • October [year]: I purc timeline of maintenance & failure: • October [year]: I purchased this vehicle. • February 11, 2026: I performed a full oil service (documented receipt attached). • April 3, 2026: while transporting my two grandsons—one of whom has autism—the vehicle suffered total engine failure while in traffic. • the safety defect: despite the engine running out of oil, the vehicle provided zero warning lights or signals. No "low oil pressure" light or "check engine" light ever appeared. This "silent failure" left me stranded in a high-risk traffic situation with a child who has special needs, as I had no warning to pull over safely. • April 8, 2026: the kia dealership confirmed the engine is seized. Improper handling of the claim: the dealership is currently refusing to honor warranty extension wty026 (15-year/150,000-mile oil pressure switch). Their refusal is based on an outdated service sticker in the window that is over 9,000 miles old, while they are ignoring my verified paper receipt from February 11, which proves the vehicle was serviced less than two months ago. The dealership is requesting a full breakdown (teardown) of the engine at my expense to determine the cause. It is my position that requiring a consumer to pay for a mechanical breakdown is an unreasonable barrier to a warranty claim—especially when they have not yet performed non-invasive diagnostic tests, such as a videoscope/borescope inspection, to check for the known oil pressure switch leak covered under wty026. Significant safety concern: the failure of the oil pressure switch (wty026) to trigger a dashboard warning is a critical safety defect. This failure led directly to a seized engine while I was transporting children. I am requesting that the department of transportation investigate this safety-system failure and that kia corporate override the dealership’s request for a consumer-funded teardown, given that I have provided proof of maintenanc.

2020 kia Sorento consuming 1. 5 or more quarts of oil every 1,000 miles. Completing oil consumption testing with kia dealer, which requires I take the car back to the dealer every 1k miles, times, so they can verify the oil levels. Last check, when issue was discovered, vehicle was down to only 1qt of oil after driving only 2k miles from previous oil change. Note: the lambda engine was initially included in the latest kia class action settlement but was dismissed per the plaintiff’s attorney in that case. However there are numerous reports from a large number of 2020 kia Sorento owners now with the same issue and running into complete roadblocks in terms of recourse as for most the issue does not begin until they exceed the powertrain warranty. Especially if they’re secondary owners and not the original owner.

The contact owns a 2019 kia Sorento. The contact stated that while driving at an undisclosed speed, there was smoke coming from the vents, with the low oil warning light illuminated. The contact stated that several oil changes were needed. While inspecting the vehicle, the contact became aware that the oil levels were constantly low. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure, and the contact was advised to go back to the dealer for a diagnostic test. The approximate failure mileage was 146,060.

The vehicle's electronic variable valve timing actuator (e-cvvt motor) failed, triggering a severe "limp home" engine mode. This defect causes dangerous vehicle surging/jumping during acceleration, limits engine output to 1500 rpm while idling, generates abnormal engine noise, and prevents the vehicle from exceeding 60 mph. This makes merging onto fast-moving highways or maintaining the flow of traffic highly hazardous. The component defect was formally diagnosed at an authorized dealership (herson’s kia) on March 30, 2026. The manufacturer, kia America, was formally notified of this powertrain hazard but has delayed providing a remedy under the pi1802/ksds warranty extension for over 49 days by demanding unrelated fluid maintenance histories for this non-lubricated electronic component. Because of the manufacturer's procedural obstacles, I am forced to operate an inherently unsafe powertrain configuration for essential transportation.

I am submitting a vehicle safety and certification concern regarding a 2023 kia Sorento hybrid that was marketed and offered for sale as a kia certified pre-owned (cpo) vehicle by shawnee mission kia, 7951 shawnee mission pkwy, mission, KS 66202. On [xxx], during an in-person inspection of the vehicle prior to purchase, I observed conditions inconsistent with expected certified pre-owned inspection and preparation standards, including inverter coolant below the minimum level, engine oil materially above the normal operating range, and deteriorated windshield wiper condition. A third-party witness was present during the inspection. Because the vehicle was being represented as certified pre-owned, I requested the vehicle’s cpo inspection checklist and supporting inspection documentation from dealership personnel. The requested documentation was not provided despite multiple follow-up requests. Subsequent written communications from dealership management acknowledged failures in dealership standards and handling related to the matter. After a formal complaint was submitted to the dealership’s corporate parent, the dealership’s general manager responded in writing that an internal review had been initiated concerning cpo preparation and documentation practices. The requested inspection and service documentation were still not produced. The dealership later confirmed in writing that the vehicle “has since sold. ” I am submitting this complaint because the vehicle was represented to consumers as certified pre-owned despite observed maintenance and inspection concerns affecting vehicle condition and safety-related systems, while supporting certification documentation was not produced upon request. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Incident details: while traveling on MD-152 (mountain road) in fallston, MD, the vehicle suffered a sudden and complete loss of motive power without any prior warning or dashboard indicators. There were no warning lights, no temperature spikes, and no mechanical noises before the engine seized. This sudden failure occurred in active traffic on a busy road, creating an immediate risk of a rear-end collision. Reason for denial & safety risk: the vehicle is currently at a certified kia dealership. I am being denied a remedy for this catastrophic engine failure due to "insufficient maintenance records. " however, the kia service department has confirmed in writing that "sludge is not a factor" in this case. Mechanically, the absence of sludge proves the engine was not neglected. Manufacturer failure: after being denied and exploring other avenues, I have learned that the 2017 Sorento 3. 3l v6 is covered under kia warranty extension wty035 (15 years/180,000 miles) for catastrophic engine failure related to head bolt and gasket defects. By using a lack of paperwork to deny a claim for a "sludge-free" engine, kia is bypassing its safety obligations for a documented manufacturing flaw. I am reporting this as a dangerous "loss of motive power" defect that mirrors existing kia engine safety recalls across their product line, and warrants federal oversight.
