What 788 owners told NHTSA about the 2017 Kia Sorento Hev

On February 16, 2023, the engine in our 2017 Kia Sorento SXL developed a sudden, loud knocking noise while driving. No dashboard warning lights illuminated at any time, including no oil pressure warning, check engine light, or other engine-related alerts. The vehicle remained fully operable and did not lose power or seize. I continued driving approximately 20 minutes home, including highway speeds up to ~75 mph. The following day, with the knocking noise worsening but still no warning indicators present, I drove approximately 25 minutes to an independent repair facility. The vehicle was then diagnosed with catastrophic engine failure attributed to oil starvation and was towed. Because the vehicle had fewer than 100,000 miles and was within the expected powertrain warranty period, we pursued a warranty review through Kia. Kia requested maintenance records, which we provided in full after gathering documentation from all service providers over a two-week period. Despite this, the warranty claim was denied, first citing gaps in initial records and later questioning oil type based on older receipts that did not explicitly state “synthetic oil.” At Kia’s recommendation, we authorized an oil pan inspection at our expense. Kia concluded that the oil filter appeared to be more than two years old, which conflicted with our documented maintenance history showing multiple oil changes during that period. Kia denied warranty coverage and quoted approximately $10,500 for engine replacement. We were advised that the replacement engine would be a remanufactured unit and that it was on backorder with no estimated delivery timeline. After approximately ten weeks without resolution, we located a compatible replacement engine at another Kia dealership and arranged transport of the vehicle there. The engine was replaced within three days for approximately $9,000. The repair included installation of a replacement engine, new spark plugs, and a passed state inspection.

On XXX, the oil warning light was illuminated in our 2017 Kia Sorento SXL and that the vehicle was leaking oil. We brought the vehicle to an independent repair facility (Tire Kingdom, Cairo, NY) for diagnosis on XXX. The repair facility provided an oral assessment with photographs indicating a suspected rear main seal leak. The engine was dry on the top but excessively wet between the engine and transmission, consistent with a significant oil leak in that area. We were advised that the vehicle could be driven in short intervals of approximately 25 minutes, provided that oil levels were closely monitored and topped off as needed. On XXX, we began driving the vehicle to transport our daughter to a train station 25 minutes away. Halfway through the trip, the vehicle began producing a metallic noise from the engine compartment. We immediately pulled over safely and turned off the engine. After stopping, we discussed next steps and then attempted to restart the vehicle. The engine started but immediately produced a severe mechanical rattling noise. It was shut off within approximately one second of startup. The vehicle was not driven further. The vehicle was then towed to Romeo Kia in [XXX]. Kia performed a diagnostic assessment and determined that the engine required complete replacement, with an estimated repair cost of approximately $10,000. This vehicle previously had a remanufactured engine installed in 2023 following a prior catastrophic engine failure. Between installations, the vehicle was maintained in normal service and was not overdue for scheduled oil changes at the time of this incident (27 days to go). At no point prior to the failure event was there clear indication of immediate catastrophic engine failure beyond the initial oil warning and leak condition. The failure progressed from a diagnosed external oil leak to immediate mechanical failure upon restart, requiring towing and full engine replacement.

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.

Following an engine replacement performed at Billion Auto Kia in Rapid City, SD, I began experiencing persistent electrical system failures in my 2017 Kia Sorento. The vehicle alarm would activate randomly without cause, including while I was inside the vehicle with the engine running. Additionally, the door locks would engage spontaneously, trapping me inside the vehicle and preventing me from exiting. The only way to exit was to forcibly pull the door handle, which triggered the alarm. I have video documentation of these incidents. I presented the vehicle to Billion Auto Kia in Rapid City, SD — an authorized Kia dealership with these exact symptoms. The service department was unable to identify a root cause and provided no repair path, returning the vehicle to me unrepaired. 7 months later, Courtesy Kia of Brandon in Brandon, FL, another authorized Kia dealership diagnosed the root cause as a failed Body Control Module (BCM). During the service visit, a Kia dealership technician personally witnessed the alarm activating spontaneously while operating the vehicle, further confirming the defect. The BCM failure was present and active at the time of the prior authorized dealer visit and was not detected. The failed BCM has also caused the gear shifter to become completely stuck, unable to shift out of Park, leaving the vehicle fully inoperable. This vehicle has had 6 recall actions performed since purchase — 4 completed after my purchase in August 2023, and two completed prior to my purchase. Despite this recall history, the vehicle has experienced an engine failure and a BCM failure within less than 3 years of my ownership. Being trapped inside a vehicle with a malfunctioning lock system represents a serious safety hazard, particularly in the event of an accident or emergency requiring rapid exit. I am requesting NHTSA investigate whether a safety defect exists in the Body Control Module of 2017 Kia Sorento vehicles and whether additional recall action is warranted.

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.

Sunroof/Moonroof After a stop light, while driving at less than 30mph, sunroof/moonroof exploded outwards. There were no surrounding cars in front or beside or in other lane direction. It was not hot or cold out. Evening time. No weather issues. If the fabric shade screen had not been closed all the glass would have fallen all over driver. There was no warning of any kind. Glass just exploded outward into a point like a mountain peak. Then glass started falling inwards into car. Took to dealership, had insurance company evaluate for repairs, insurance approved repairs performed by dealership. Dealership service writers said this has happened on other kia's.

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.

I found that he ignition key can be removed from my 2017 Kia Sorento while the transmission is not in the Park position. This is a shift interlock failure. Under FMVSS 114, the key must be trapped in the ignition unless the transmission is confirmed in Park. This defect caused the vehicle to roll down my driveway after my wife & daughter exited the car & were unloading groceries. The vehicle was purchased in April 2026 from a used car dealer lot. The defect was discovered shortly after purchase. No dealer repair has been performed yet. I am contacting Kia Consumer Affairs requesting a goodwill safety repair under FMVSS 114. Component affected: Power Train — Automatic Transmission — Shift Interlock System

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.

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.

Upper fuel pump module, on top of fuel tank, is leaking fuel from a crack in fuel pump port where fuel hose connects. Fuel can be seen on top of upper fuel pump module and can be seen leaking from fuel pump port, and can be seen on exterior of gas tank. Also fuel odors were present. This could be a fire hazard. The manufacturer issued TSB FUE 064 for this exact issue for vehicles produced from March 31, 2017 through July 24, 2019. Local dealer will not cover the vehicle because it was manufactured in February of 2017. The vehicle has not been inspected by manufacturer, police, of insurance company. There were no warning lamps, messages prior to failure. The symptoms were fuel on top of module, fuel odor, and fuel stain on exterior side of fuel tank

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

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.

I am submitting a safety complaint regarding a **2017 Kia Sorento SXL** equipped with a **3.3L Lambda V6 engine**, which experienced **sudden and catastrophic engine failure** at approximately **137,000 miles**. Prior to failure, the vehicle exhibited **progressively worsening engine knocking and vibration**, indicating internal engine damage. Despite these warning signs, the failure occurred **abruptly while driving at highway speed**, resulting in a **sudden loss of power**. This incident created an **immediate safety hazard**, as I was traveling in active traffic and was forced to quickly maneuver to avoid surrounding vehicles. The unexpected loss of propulsion significantly increased the risk of a collision. The nature of the failure appears to be consistent with **internal engine component failure (such as connecting rod bearing failure)**, which is not typical for a properly maintained modern engine at this mileage. Importantly, my vehicle was manufactured in **November 2016**, placing it within an early production period for this engine. There is evidence from technical service information and consumer reports suggesting a **pattern of premature internal engine failures** in this engine family, particularly involving **rod bearing wear leading to catastrophic failure**. This raises concern that the issue may represent a **systemic defect** rather than normal wear and tear. I am concerned that other vehicles with this engine may experience similar failures **without sufficient warning**, potentially resulting in dangerous driving situations, especially at highway speeds. I am requesting that NHTSA: • Review this incident as a **potential safety-related defect** • Evaluate whether similar complaints exist involving the **3.3L Kia Lambda V6 engine** • Determine if an **investigation or recall** is warranted I am able to provide supporting documentation, including maintenance records, diagnostic findings, and repair estimates upon request.

The contact owns a 2017 Kia Sorento. The contact stated that while driving at 35 MPH, there was an abnormal knocking sound coming from the engine, and the vehicle lost automotive power. The oil pressure warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed with excessive oil consumption. An oil consumption test and combustion cleaning were performed; however, the failure persisted. The vehicle was taken to an independent mechanic, who confirmed the failure. The contact was advised to park the vehicle outside. The manufacturer was not notified of the failure. The failure mileage was 19,000.

On 3-21-26 I noticed the smell of gasoline after driving the vehicle. Upon inspection a noticeable fuel leak from the top of the fuel tank was evident from underneath the vehicle. Further inspection found fuel leakage at the fuel pump outlet line. After online research it was found that other vehicles of this type have hairline cracks on the fuel pump outlet causing fuel to spray out under pressure. Fuel pump assembly replacement has repaired the problem. No indication other than the smell of gasoline was noted at any time. This is a safety hazard that should be addressed ASAP. Part removed has only been inspected by me. Part is available. If I had not been diligent in addressing this problem the consequences could have been catastrophic. The fuel outlet on a high pressure pump should have never been allowed to be made of plastic. People's lives are at risk!

My 2017 Kia Sorento with approximately 175,000 miles experienced engine failure involving the engine and engine cooling system. The vehicle began showing symptoms including engine shudder, reduced acceleration, and a check engine light. These symptoms worsened and were diagnosed by a Kia dealership as internal engine damage, specifically a failure in cylinder 4. The dealership advised that the engine would require full replacement at an estimated cost of approximately $9,600. The failure creates a potential safety concern because the vehicle experiences loss of power during acceleration, which could increase the risk of an accident, especially when merging into traffic or driving at highway speeds. The issue was confirmed by an authorized Kia dealership, Community Kia, after performing diagnostic testing. The dealership completed multiple recall and service campaigns but determined that the engine was not eligible for replacement because a required diagnostic code associated with the knock sensor detection system did not appear. To my knowledge, there is no clear documentation confirming that the knock sensor detection system update was installed on the vehicle prior to the engine failure. If this system was not installed, the diagnostic code required to qualify for engine replacement may not have had the opportunity to trigger. Prior to the failure, the vehicle displayed warning symptoms including a check engine light, engine vibration, and loss of power. These symptoms appeared before the dealership inspection and diagnosis. This complaint is being submitted due to concern that the engine failure occurred despite known issues associated with this engine type, and that the failure creates a potential safety risk due to sudden loss of power while driving.

I own a 2017 Kia Sorento SX 3.3L V6 FWD with 68,000 miles and full documented service history. The HECU (Hydraulic Electronic Control Unit) failed, disabling the ABS and electronic stability control system. This is a known defect covered under Kia's settlement for some Sorento vehicles with identical HECU components. Despite the same defect occurring on my 2017 model, it was excluded from the settlement without justification. I paid out of pocket for the HECU replacement which cost $2645. This is a serious safety defect affecting the braking system. I am requesting NHTSA investigate whether the some additional 2017 Sorento models should be included in the existing settlement or subject to a separate recall given the identical nature of the defect across model years.
