2017 Kia Sorento: engine knocking or ticking

Filed Sep 24, 2026 · Engine · TX

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 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.

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.

bought car from carmax. engine knock sensor went bad and engine is knocking. kia states engine is not origional and was taken from a junk yard, both kia and carmax are refusing to fix eventhough I am doing payments and it is a known kia issue for this car. Kia charged me 350$ to run test and cleared the light but informed me my engine is going to blow. carmax is refusing to do anything but still wants us to pay the 9k we owe on the car eventhough its broke.

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.

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.

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.

Driving up a small hill when you hear this knocking noise.The car got to the top of the hill and shuts off no engine no turn over spent 198 to get it towed then comes to find out that it is because the car had no oil from what the mechanic told me. The car had oil but apparently only this model has issues with not having oil and you have to do an oil change every 4 months rather than 10,000 miles and I just brought the car.

I was driving and heard a loud noise. The car started to hesitate and was making a knocking noise. I pulled over and had it towed where I was told it was a rod bearing failure and I needed a new engine. It had 130,000 miles. I have been reading online and found a lot of vehicles with the same engine as mine where this has happened and there are no recalls. Engines size 3.3L V6. Right now the car is sitting. I still owe on it and can’t afford to have it fixed. The oil was changed regularly. It was changed four weeks before this happened. No warnings.
