1. Headlight Failure (Recall Malfunction): Last year, my headlights began intermittently shutting completely off while driving at night, creating an immediate visibility hazard. Kia of Palmdale performed the designated recall repair, but the dangerous defect remains. The headlights still shut off unexpectedly while the vehicle is in motion. 2. Shift Lock Failure: In May 2024, just two months after purchasing the vehicle, the shift lock mechanism failed completely. This intermittently prevented the vehicle from shifting properly out of park, creating an entrapment and stalling hazard. 3. Catastrophic Engine Failure: Last week, the 3.3L V6 engine suffered a sudden, catastrophic mechanical failure while driving. This caused an immediate loss of motive power, putting me and other drivers in severe danger.

Yesterday our car was making a knocking noise. It lost power temporarily. Upon pressing the gas pedal to the floor we were able to get up to 30 mph. We made it to a repair shop. They looked at it today. The Dip stick showed no oil. The did an oil change and it was down 3 quarts of oil. We just had the oil changed 3 months ago on June 20. No check engine light came on. No warning at all . We were driving on a road with no shoulder, so this was dangerous if the engine were to fail before we got to repair shop. They said we need a new engine and it will cost just under $10,000. It seems that many people are having this exact same problem.

My 2017 Kia Sorento experienced a catastrophic, sudden engine lockup on the roadway due to a known manufacturing defect involving rod bearing failure. This defect caused complete loss of motive power and stalled the vehicle on the road, creating an extreme safety hazard for myself, my passengers, and surrounding motorists.Prior to the failure, the vehicle heavily consumed its own motor oil at a dangerous rate of nearly 5 quarts every 1,000 miles. I repeatedly attempted to address this with Kia, completing three separate official oil consumption and combustion tests. The vehicle failed all three tests. Despite documented failures of these critical safety components, Kia Corporate and the local dealership, court Kia, issued bad-faith warranty denials. As a direct result, I was forced to drive a dangerously unstable vehicle for 8,148 additional miles until the engine permanently and violently seized on the road.After being towed, the engine was confirmed to be completely locked up. My husband subsequently dropped the engine's oil pan and discovered a pieces of physical rod bearing debris and pieces of a snapped timing chain floating inside. The vehicle had full engine oil at the time of failure, as we were constantly topping it off to counteract the severe consumption defect.Manufacturer and Dealer Misconduct / Safety Cover-Up:The servicing dealer, Regal Kia, and Kia Corporate Case Manager Jennifer (who previously denied the vehicle after the consumption test failures) have actively colluded to falsify safety records to escape their lifetime warranty obligations under the federal engine class action settlement.The dealership deliberately withheld the vehicle's diagnostic trouble codes (specifically camshaft codes triggered when the timing chain snapped), falsely telling Kia Corporate that "no codes" existed. They fabricated a false history, claiming I stated the vehicle "stalled and the oil light flickered" prior to arrival, despite the vehicle being towed in with a p

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.

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 the federal safety agency investigate whether a safety defect exists in the Body Control Module of 2017 Kia Sorento vehicles and whether additional recall action is warranted.

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.

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

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 the federal safety agency: • 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.

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.
