I was driving my 2015 Kia Sorento on [XXX] south of the [XXX] junction when the engine suddenly started making severe mechanical noise and the vehicle seemed to have significantly reduced power. This is a remote stretch of highway with no usable shoulder. I had my son with me and had to immediately navigate with reduced speeds and power until I could reach a pullout and get safely off the highway. The sudden engine problem at highway speed created a serious safety concern because I could not immediately get the vehicle out of the traffic lane, and had no immediate shoulder I could pull onto. The vehicle was subsequently inspected by Oxendale Kia dealer. The dealer diagnosed catastrophic internal engine bearing failure. The vehicle has approximately 160,000 miles. The vehicle and failed engine are currently at the Kia dealer. Availability of the failed engine/components for inspection: UNKNOWN pending confirmation from the dealer. Prior warning lamps or warning messages: No engine lights. An airbag light was illuminated. There were no other warning immediately before the failure. The failure has been confirmed by the Kia dealer. Kia America has also opened a corporate case and is obtaining the dealer's diagnostic information, but to my knowledge Kia corporate has not separately physically inspected the vehicle. I am aware that NHTSA has previously investigated loss-of-motive-power issues involving 3.3L Kia Sorento engines, including model years around mine. I am submitting this complaint so this catastrophic bearing failure and highway safety event can be evaluated with any similar reports.

NHTSA complaint #11763639 — an unverified report by a vehicle owner.
My 2023 Kia Sorento has experienced repeated failures involving the engine, transmission/powertrain, and electrical wiring system. The vehicle has been inspected and repaired multiple times by authorized Kia dealerships, including Kia of Round Rock and Clay Cooley Kia in Irving, and the repair history and vehicle are available for inspection upon request. The most serious incident occurred on XXX, while I was driving on the [XXX]. The vehicle suddenly lost acceleration, began smoking, and experienced a catastrophic engine-related failure, creating a serious safety concern while I was traveling on a high-speed roadway. The vehicle had to be towed to Clay Cooley Kia, where it remained for approximately three months and the engine and related components were replaced. After receiving the vehicle back on XXX, a significant oil leak developed approximately five days later. The vehicle was returned for service, the problem was confirmed, and it ultimately required a transmission replacement. On approximately XXX, multiple/all dashboard warning lights illuminated, and Kia subsequently replaced the wiring harness. The vehicle continued to experience problems and was towed to Kia again. In XXX, Kia determined that another transmission replacement was necessary. The vehicle has now had three transmissions associated with it, in addition to the replacement engine and wiring harness. XXX, the vehicle is still malfunctioning despite being on its third transmission. Current symptoms include the RPMs suddenly surging/revving higher than expected, jerking while driving, and a noticeable delay between pressing the accelerator and the vehicle accelerating. These symptoms create a safety concern because I cannot confidently predict how the vehicle will respond when accelerating, merging into traffic, crossing an intersection, or traveling at highway speeds. I am concerned that the repeated engine failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11763054 — an unverified report by a vehicle owner.
I am filing this complaint regarding a 2016 Kia Sorento, VIN [XXX]. The vehicle suddenly broke down while my [XXX] daughter was driving in [XXX] and was taken to Sooner Kia in [XXX]. The dealership diagnosed the engine as seized and stated that it failed because there was no oil, requiring engine replacement. We dispute that conclusion. Within approximately five minutes of the breakdown, my daughter checked the oil at her father’s direction, and the level appeared normal. A mobile mechanic later inspected the vehicle and also reported that the oil level was normal and appeared clean. Sooner Kia now claims the engine was “bone dry” and that lack of oil caused the seizure. We have requested documentation showing how much oil was found, whether any oil was drained, what testing was performed, what internal damage was identified, and what evidence proves that oil starvation caused the failure. We have not received documentation establishing the cause. This is concerning because NHTSA previously investigated loss of motive power involving 2016–2017 Kia Sorento vehicles with 3.3L Lambda II engines under PE23-019. Kia later created extended warranty campaign WTY035 for certain related failures. Please document this complaint and review whether this engine failure may be related to those known issues. We are being asked to authorize an expensive engine replacement without evidence supporting the dealership’s conclusion.

NHTSA complaint #11762746 — an unverified report by a vehicle owner.
In early July, my vehicle's check engine light turned on. I took it to a reputable local mechanic in Sachse, Texas, who had the vehicle for approximately two weeks. He was unable to determine the cause of the issue but informed me that there was an existing recall and that the dealership should be able to address the problem at no cost to me. I then took the vehicle to the Kia dealership. The dealership informed me that there was an extended warranty for the engine and that if their diagnosis determined that the issue was covered under the warranty extension, they would repair it. This is what they texted me: Tech performed Compression test 1 .205psi, 2. 220psi, 3. 260psi, 4. 255psi all cylinders have excessive reading for dry compression test. Tech performed leak down test on all cylinders 1. 21% leak down coming from exhaust side, 2.61% leak down coming from exhaust side, 3. 10% normal, 4. 10% normal. Air leakage from exhaust system defective exhaust valves. Tech performed Cooling system pressure test for 20 minutes with no pressure loss. Ruling out head gasket. Tech evaluated Intake/Exhaust CVVT current and setpoints. Tech determined timing is jumping from back pressure of Clogged Catalyst Converter. Recommending replacing engine due to mileage and exhaust manifold. The dealership's recommended solution was to replace the entire engine. Currently, there is a recall concerning 2017 Kia Sorentos involving engine crankshaft issues. See NHTSA Recall No. 17V586000. I contacted the manufacturer, and they stated that they do not believe my vehicle is covered by the recall. However, I believe the issues identified with my vehicle may be related to the same underlying engine problems addressed by the recall, and I am concerned that the manufacturer is denying coverage rather than properly addressing the issue under the applicable recall or warranty. My engine is experiencing issues that appear similar to those described in the current NHTSA.

I am filing this complaint regarding my 2019 Kia Sorento and an engine failure related to Kia’s Product Improvement Campaign/KSDS (Knock Sensor Detection System) campaign. I purchased this vehicle used in 2022. Prior to the engine failure, I was never notified of any Product Improvement Campaign affecting my vehicle. Had I been notified, I would have immediately taken the vehicle to an authorized Kia dealership to have the campaign completed. My engine subsequently failed, and Kia denied coverage, stating that the Product Improvement Campaign was not completed before the engine failure occurred. Kia stated that notices were mailed to affected owners, but they have not provided me with documentation showing when my specific notice(s) were mailed, what address they were sent to, or proof that I was properly notified. I am concerned that affected owners may not be receiving adequate notification of this engine-related issue before a failure occurs. An engine failure can create a serious safety concern, especially if it occurs while driving, and owners may unknowingly continue operating vehicles affected by this condition without having the opportunity to complete the required update. I am requesting that NHTSA review this matter to determine whether Kia’s notification process for this campaign was effective and whether additional investigation is needed regarding engine failures associated with this issue. Vehicle Information: Year: 2019 Make: Kia Model: Sorento Date of engine failure: June 2026 I have documentation from Kia Customer Care regarding their denial of coverage and their statement that the campaign was not completed prior to engine failure.
NHTSA complaint #11762150 — an unverified report by a vehicle owner.
I own a 2021 Kia Sorento 2.5L Turbo AWD with approximately 150,000 miles. In the evening, while driving home after dinner with my daughter in the vehicle, I was traveling in the area of [XXX] and [XXX] when the vehicle displayed a “STOP SAFELY IMMEDIATELY” warning. The vehicle unexpectedly slowed down/appeared to brake on its own while I was driving. There was no check-engine light at that time and the warning did not remain on, so I did not initially know what caused the incident. Approximately two weeks later, the vehicle developed delayed shifting from 1st to 2nd gear. RPM increased from about 2,000 to 3,000 before the next gear engaged. Switching from ECO to Comfort mode initially seemed to help, but later that day the problem worsened even in Comfort mode and also began occurring from 2nd to 3rd gear. The check-engine light then came on. O'Reilly Auto Parts scanned the vehicle and reported codes P0868/P086800 (Transmission Fluid Pressure Low) and P193B79 (High Pressure Electric Oil Pump Performance). Kia has not yet diagnosed the current problem, and the vehicle is available for inspection. Kia checked my VIN for recalls sometime in 2025 and advised there was no open recall. I am aware of Kia Safety Recall SC250/NHTSA Recall 22V-760 involving the 8-speed DCT electric oil pump on certain 2021-2022 Sorento vehicles. I am concerned because my vehicle experienced the “STOP SAFELY IMMEDIATELY” warning and unexpected slowing and now has worsening transmission symptoms and related diagnostic codes. I am concerned the vehicle could unexpectedly lose drive power while being driven. I request NHTSA review whether my vehicle's condition may be related to the existing safety defect and whether additional vehicles should be investigated.

The vehicle was later towed to the local dealer, who diagnosed that the engine had failed and needed to be replaced. The cause of the engine failure was unknown. The vehicle was not yet repaired. While purchasing the vehicle, the contact was advised to constantly monitor the engine oil due to a known oil consumption issue. The manufacturer was notified of the failure and informed the contact that the vehicle was included in the extended warranty program. The failure mileage was 125,202.
NHTSA complaint #11761295 — an unverified report by a vehicle owner.
On or about XXX, my KIA Sorento LX FWD Auto 2.4-liter engine with an approximate mileage of 36,000, began having drivability problems, none of which occurred before that date. On XXX the vehicle was serviced at Ourisman Chantilly Kia (VA051) for a Voluntary Emissions Service Campaign (SC340) THETA II 2.4L GDI ECM S/W Upgrade. Records reflect that it was a Theta II Emissions Logic Improvement 250A21R1 0.3 M/H. This was a voluntary campaign from Kia America, Inc., [XXX]. Failure to have this performed, as cited from the Kia Corporate Headquarters, could nullify warranty/warranties. What ensued was a vehicle that stalled, seized, hesitated, and/or jolted at low speeds that had the potential to cause severe injury or accident. Uncontrolled rough accelerating and seizing is a serious complaint, and the causation can be linked to the dealership performing the voluntary recall where the vehicle was purchased on March 15, 2015, in [XXX]. Further, this vehicle has a full and complete record of all repairs and symptoms, which includes, and is not limited to, maintenance, Service Campaign, Service Action, Recall, and Product Improvement. This vehicle, included in a class of vehicles with a history of potential engine failures, has a Lifetime Engine Warranty extension coverage included in PI1802 Y/Z Engine R&R Warranty Bulletin 2020-26 and PI1802W/X Warranty Bulletin 2018-10. Therefore, when the records were reviewed for the initial Voluntary Emission Service Campaign recall code SC234 completed in 2022, along with my former NHTSA Complaint Number XXX submitted electronically, an apparent history of obfuscation relating to material safety concerns emerges. KIA America, Inc. sold this Kia as a five-star safety rated vehicle. It now makes me feel uneasy with its defective drivability.

NHTSA complaint #11761133 — an unverified report by a vehicle owner.
I am filing an official safety complaint against the manufacturer for refusing to perform federally mandated safety recall repairs on my vehicle. My vehicle is impacted by critical safety recalls involving high-severity fire risks, specifically the Hydraulic Electronic Control Unit (HECU) electrical short circuit risk. Corporate Customer Care and my local authorized dealership have officially refused to schedule or perform these safety recall repairs. The representatives explicitly stated that my vehicle is denied service because I purchased it used from a third-party private owner, and because I do not possess complete historical maintenance records. The manufacturer is conflating civil class-action lawsuit requirements with federally mandated safety recalls. Under the National Traffic and Motor Vehicle Safety Act, a manufacturer cannot legally condition or deny an active, free safety recall repair based on a vehicle's third-party purchase history or maintenance records. Due to poorly trained employees at both the dealership and customer care offices, I have faced constant misinformation that has wasted an immense amount of my time. Because this non-compliance has caused a severe safety hazard to drag on for an extended period, I am also requesting that a loaner vehicle be provided immediately until this vehicle is made safe to drive. The manufacturer has logged these denials and communications under an active corporate file, which I can provide directly to investigators upon request. I request that the NHTSA investigate this non-compliance and instruct the manufacturer to immediately authorize the local service center to perform all open fire safety recall remedies without cost or penalty.

I went in a few months ago for a routine oil change. My car has had zero operating issues since I had the engine replaced around 5 years ago. They told me that I need to have a voluntary emissions update performed, so I gave consent. (The letter I received a few days later referred to it as "Voluntary Emissions Service Campaign.")On the way home, it seemed to drive rougher. I figured it was relearning some of the basic operating values. The following morning, it idled rough and then when I began driving, it would lurch forward irradically for the first one or two minutes of driving. I called the dealership and they insisted that it was coincidence. They said they will look at it, but there would be a charge. I have noticed a pattern since then. During normal driving, it is now smooth. It only happens on cold starts. Allowing it to idle elimiates the issue. However, it continues to idle rough on cold starts. If I drive it after it warms up, however, it does lurch forward. After this, it drives normal. Today I went in to the dealership for another oil change and asked about it. They continued to insist that it was impossible, but that I could leave it overnight and pay to have it looked at with the understanding that the two cannot be related. The safety issue is that it will literally make the car lurch forward when barely touching the gas. If this continues to worsen, it will cause a wreck. It has not been formally inspected, but I can provide dash cam footage.

On multiple occasions, my 2023 Kia Sorento has experienced an intermittent failure where numerous dashboard warning lights and alerts illuminate and the engine will not start. During the failure, the brake pedal becomes very stiff and the vehicle cannot be shifted out of Park. The problem is unpredictable and has left the vehicle disabled. The vehicle was taken to a Kia dealership for diagnosis. The dealer initially stated that the battery was not properly secured and was moving around, possibly contacting nearby electrical components. They told me the issue had been repaired. However, when I returned to pick up the vehicle, the exact same failure occurred again in the dealership parking lot before I was able to leave. The warning lights came on and, after the vehicle was turned off, it would not restart. The dealer has therefore been able to directly observe the repeated failure. The exact component causing the malfunction is still unknown. I am concerned that this may be an electrical or grounding issue and that the vehicle could become disabled unexpectedly while in use.

My kids and I were driving when my engine started making a loud noise. I pulled over and turned it off for a few minutes then I turned it back on. It worked for another mile or so then started making the noise again and died while I was driving at about 55-60 miles an hr. I was able to pull over, put it in park and turned the key off....it wouldn't turn back on and the check engine light came on. When I had someone check it out for me it was about 4 quarts low on oil (it never gave me a warning about the oil and the oil light never came on) and the check engine code was P0024. Oil was added and the camshaft position sensor has been replaced. It starts now but it won't stay on and when it is on it makes a loud screeching sound that isn't coming from the serpentine belt and a loud knocking sound.

Engine, a Lambda 3.3 v6 started knocking periodically and consuming oil at about a half a quart a week. It is a know problem with this motor and well documented in its existence in all Hyundai and Kia vehicles using this engine. We now have been told that the head bolts are partially stripped. Another known problem and we are consuming coolant. This can is not trustworthy and could fail at any time. We are still paying off the loan if it matters.

The contact owns a 2025 Kia Sorento. The contact stated that while driving approximately 75 MPH, the rear windshield wiper was moving with the switch turned off. The contact turned the rear windshield wiper to high, then low, and the wiper finally turned off. The contact continued driving and the vehicle suddenly stalled, and the message Press Button to Start Engine message was displayed. The vehicle continued to coast in neutral, and then decelerated to approximately 65 MPH. The contact pressed the start button and the accelerator pedal, and the vehicle failed to move immediately. The contact stated that after several attempts, the engine revved as needed. The contact stated that while continuing to drive, the steering wheel was hot, the radio screen was blacked out, and the horn failed to sound. When the radio screen was illuminated and displayed the information on the screen, the contact became aware that the GPS had reset to an erroneous location. The rear windshield wiper independently activated again. The contact noticed a burning odor while continuing to drive the vehicle. After the contact arrived to the destination, the contact had to press the button four times before the vehicle turned off. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the issues. The failure mileage was approximately 56,000.
