Configuration applicability

Unresolved · not yet pinned

This model year was built in 6 reviewed configurations (3.3L All-Wheel Drive; 3.3L Front-Wheel Drive; 2.4L All-Wheel Drive; 2.4L Front-Wheel Drive; 2L All-Wheel Drive; 2L Front-Wheel Drive); configuration-scoped findings can differ between them.

To verify: Enter the VIN, or read the engine/drivetrain from the door-jamb label or window sticker, to pin the exact configuration.

Ownership headache outlook

The stated ownership horizon enters the observed band for Engine Oil Pressure Switch Leak investigation; this is a scenario band, not a failure probability.

Most inspection-relevant: Engine Oil Pressure Switch Leak investigation — this is the issue to focus the pre-purchase inspection on.

What each horizon reaches

  • 1 yrAbout 12,000 mi — reaches the observed onset band for Engine Oil Pressure Switch Leak investigation, which your window is inside.
  • 3 yr (yours)About 36,000 mi — reaches the observed onset band for Engine Oil Pressure Switch Leak investigation, which your window is inside.
  • 5 yrAbout 60,000 mi — reaches the observed onset band for Engine Oil Pressure Switch Leak investigation, which your window is inside.
12,000 annual miles · 3-year ownership horizon · Service history is unknown unless verified by the buyer. These are observed report bands, not failure probabilities.

Why it matters
The official record identifies a condition that deserves candidate-specific inspection and record verification.

Observed complaint mileage band; not an incidence probability

Reported onset roughly 24109,500 mi (median 48,013 mi).

Your window enters the onset band.

Based on 4 usable reports (7 censored). Complaint mileage is an observed report band, not a population incidence estimate.

What to inspect

  • Check the VIN for open NHTSA actions, then ask the inspector to test the named system and document the result.

Pro check: Independent pre-purchase inspection.

Mitigation

  • Treat the official record as a targeted inspection lead, not proof that this candidate has the condition.

The official record identifies a condition that deserves candidate-specific inspection and record verification.

“Engine Oil Pressure Switch Leak In a letter dated September 30, 2021, Mr. Gerald James (the petitioner) requested that NHTSA conduct an investigation of the Model Year (MY) 2015-2017 Kia Sorento equipped with 3.3L V6 ?Lambda? engines for ?severe oil leaks? from the oil pressure switch (OPS) that could ?lead to engine failure? with little warning to the driver. Mr. James based this request on his own experience and data found in NHTSA?s Vehicle Owner Questionnaire (VOQ) database. NHTSA reviewed the material cited by the petitioner, information submitted by Kia, NHTSA?s testing, and other pertinent information in NHTSA databases.On November 12, 2021, ODI opened Defect Petition DP21-002 to evaluate the petitioner?s request. ODI performed an analysis that included evaluation of the petitioner?s vehicle, searches of ODI complaints from vehicle owners, non-dealer field reports, manufacturers? supplemental information relating to design of the component, and component testing performed by ODI.On December 16, 2021, ODI and Kia North America performed a joint inspection on the petitioner?s vehicle. ODI and Kia agreed the OPS was leaking oil and observed oil in the crevices atop the engine block. The vehicle received a new replacement OPS and was delivered back to the petitioner. The original part that was removed from the subject vehicle was retained by ODI for further analysis.As of December 30, 2022, for the MY 2015-2017 Kia Sorento population of 161,519 vehicles with 3.3L engine, NHTSA reviewed internal data and has identified no consumer complaints or field reports in its database, with unique Vehicle Identification Numbers (VIN), citing engine failure or stalling related to the petition?s allegation of defective OPS. When combined with the supplemental warranty and technical analysis from the manufacturer, field report and customer complaint data in response to the Information Request letter sent, NHTSA identified no unique VINs alleging engine failure or stalls caused by OPS leaking on the subject vehicles named in the petition.On April 4, 2022, the Vehicle Research and Test Center (VRTC) performed testing of the petitioner?s component (OPS) based on testing protocol consistent with Kia?s specifications for the subject vehicle. The testing involved the petitioner?s original OPS in a controlled system to replicate the subject vehicle?s oil pressure, flow, and temperature. VRTC determined that a vehicle would have to miss more than a dozen oil change intervals to reach low engine oil capacity. Testing also revealed the OPS would operate, as manufacturer intended, illuminating the vehicle?s MIL to alert the driver of lower oil pressure.In April of 2022, Kia North America issued a warranty extension that extended the coverage of the Oil Pressure Switch from 5 years/60,000 miles to 15 years/150,000 miles on MY 2014-2018 Sorento, MY 2014-2016 Cadenza, and MY 2015-2018 Sedona vehicles, all equipped with the 3.3L Lambda engine. The extended warranty coverage includes diagnosis, repair, and applies to customers experiencing engine oil leaking from the engine or if the engine oil pressure warning light stays illuminated after the engine is turned on.After a thorough review of the material submitted by the petitioner, information already in NHTSA's possession, testing performed by VRTC, technical information provided by Kia, the potential risks to safety implicated by the petitioner's allegation, NHTSA does not believe that an engine failure due to the alleged defect is likely and does not warrant a formal investigation. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA?s reasons for denial of the petition will be publi”

What would change this answer

verified remedy

A newly verified completed remedy with configuration-specific eligibility for Engine Oil Pressure Switch Leak investigation could improve the recommendation.

contradictory source

A reviewed official or independent source that materially contradicts the claims for Engine Oil Pressure Switch Leak investigation would force confidence and verdict review.

changed applicability

Reviewed evidence that includes or excludes a different year, engine, drivetrain, trim, or VIN population would change which issues apply.

lost exposure eligibility

A verified production denominator and eligible time-at-risk cohort are required before normalized comparative year guidance can strengthen.

Applied assumptions

  • · 12,000 annual miles
  • · 3-year ownership horizon
  • · Service history is unknown unless verified by the buyer.

Sharpen it further

  • Add mileage — it places the onset bands against your ownership window.
  • Add the asking price — it weighs the findings against what you would pay.
  • Set your annual miles — assumed 12,000; it sizes the window.
  • Choose a horizon — assumed 3 years; it sets the window length.

What we could not verify

Every dimension is listed — including the ones we do not have — each with the concrete next step to close it.

  • ConfigurationPartial

    This model year was built in 6 reviewed configurations (3.3L All-Wheel Drive; 3.3L Front-Wheel Drive; 2.4L All-Wheel Drive; 2.4L Front-Wheel Drive; 2L All-Wheel Drive; 2L Front-Wheel Drive); configuration-scoped findings can differ between them.

    Next: Enter the VIN, or read the engine/drivetrain from the door-jamb label or window sticker, to pin the exact configuration.

  • VIN recall & historyNot verified

    A VIN recall check was not handed to this page, so recall status and title/odometer history for this exact car are unchecked.

    Next: Run this VIN on NHTSA’s recall lookup and request a title/history report to confirm open recalls and past events.

  • Repair costNot verified

    No sourced repair-cost range is available for the named issues in this release.

    Next: Get a written repair estimate for the named issue from an independent shop before you negotiate.

  • Market price contextNot verified

    No asking price was entered and no licensed market-value feed is integrated, so price fairness is not assessed.

    Next: Compare the asking price against recent local listings for the same year and configuration.

  • Onset evidencePartial

    Onset bands rest on a limited number of usable reports; treat the band edges as approximate.

    Next: Weigh the onset band as a reported-onset range, not a failure probability, and confirm condition by inspection.

Coverage & methodology

Evidence: Medium confidence— Enough evidence to decide; some sources are thin or single-origin.

6 of 5 expected sources present · methodology m1-v4-authority-cohort.

  • · Public complaints and recalls do not estimate failure probability.
  • · Observed mileage bands describe reported onset only.
