I TOOK MY 2016 KIA SORENTO IN 2MOS (3/16) AFTER I PURCHASED FOR ACCELERATION ISSUES. THE FIRST TIME IT WAS LUNGING WHEN ACCELERATING AND THE RPM'S WOULD GO TO 5-6 THEN DROP TO 0, THEN STABILIZE AT 2. KIA DID SOME RE-COMPUTER PROGRAM TO ADDRESS ISSUE. IT IS STILL NOT RESOLVED BUT WAS NOT AS BAD AFTER THE RE-PROGRAMING. WELL, NOW IT IS REALLY BAD SO TOOK IT BACK (4/17) BECAUSE IT STALLS ON ACCELERATION. I WAS TRYING TO ENTER A HIGHWAY, ACCELERATED KIA STALLED AGAIN RPM'S UP TO 5-6 DOWN TO 0, BUT HAD TO QUICKLY MOVE TO SHOULDER OR SEMI-TRUCK WOULD HAVE HIT ME. ONCE I STOPPED AND STARTED AGAIN, IT ACCELERATED. YESTERDAY, 4/5/17, DRIVING TO WORK IN RUSH HOUR TRAFFIC ON NJ E. I-78, WAS IN MIDDLE LANE MERGED TO LEFT LANE TO PASS (60 MPH), ACCELERATED KIA STALLED (RPMS UP THEN DOWN), I HAD TO BRAKE TO INDICATE TO CAR BEHIND ME OR I WOULD HAVE BEEN IN A HORRIFIC CRASH BECAUSE THIS ROADWAY CARRIES A MASSIVE AMOUNT OF SEMI'S. I WAS SCARED FOR MY LIFE AND MY HEART WAS RACING!! I WAS ABLE TO MOVE BACK TO CENTER LANE WHERE I REMAINED. THE KIA KEPT HAVING THE ACCELERATION ISSUE ALL THE WAY TO WORK AND ON THE WAY HOME SO I TOOK IT TO THE KIA DEALER. I DON'T KNOW IF THEY CAN REPLICATE THE ISSUE BUT I AM NOT DRIVING THIS VEHICLE UNTIL IT IS RESOLVED. I SEE ON LINE THERE ARE NUMEROUS OTHERS WITH THIS SAME ISSUE AND NO RECALL??!! I GUESS SOMEONE HAS TO DIE FIRST. NHTSA YOU NEED TO DO SOMETHING BEFORE SOMEONE LOSSES THEIR LIFE. THIS IS NOT SOME SMALL PROBLEM. KIA CERTAINLY IS NOT INTERESTED IN BEING PRO-ACTIVE. THE SERVICE AND SALES PEOPLE SAID "WE HAVE NEVER HEARD OF THIS ISSUE" MY REPLY "YOU BETTER LOOK ON LINE AT CONSUMER COMPLAINTS". OF COURSE THEY WANTED TO USHER ME OUT OF THE SHOWROOM TO A "QUIET TABLE" SO OTHER PROSPECTIVE BUYERS WON'T HEAR. WORD OF MOUTH MY FRIENDS, WORD OF MOUTH. SAD A SALE MEANS MORE TO KIA THEN A LIFE!!

PE23019 · Loss Of Motive Power

Opened Nov 13, 2023 · Closed Jul 23, 2024

Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling:engine:oil/lubrication:seals/gaskets

On November 13, 2023, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE23-019) to investigate allegations of loss of motive power relating to head gasket and/or head bolt failure in Model Year (MY) 2016-2017 Kia Sorento vehicles equipped with the 3.3 L Lambda II engine. When the investigation was opened, ODI had received 13 Vehicle Owner Questionnaires (VOQs) related to reports of loss of motive power. In an information request letter dated November 30, 2023, ODI requested technical information and failure data relating to the alleged defect in the subject MY 2016-2017 Kia Sorento as well as several peer vehicle populations which share the 3.3 L engine. In its February 26, 2024, response to ODI’s information request, Kia provided 2022 customer complaints (including techline and field reports) and 1738 warranty claims representing 2411 unique vehicles within the subject vehicle population. Of the customer complaints provided by Kia, they identified only 53 unique allegations of a loss of motive power resulting from the alleged defect. Kia determined that the remaining reports were minor vehicle drivability or engine performance issues. ODI reviewed the information provided by Kia, along with additional VOQs submitted to NHTSA following the opening of the investigation. When eliminating duplicative reports across the data sources, the total number of allegations of loss of motive power relating to the alleged defect in the subject vehicles is 77, representing an incident report rate of 59 per 100,000 vehicles. The MY 2016 Kia Sorento exhibited both the highest overall complaint rate and loss of motive power report rate across all subject and peer vehicle populations, representing an incident report rate of 102 per 100,000 vehicles. Across all data sources, there are no allegations of crashes or fires relating to the alleged defect. The one injury incident reflected in the failure summary table above is related to a consumer who was reportedly burned (minor burn requiring medical attention) while attempting to remove the coolant reservoir cap following a loss of motive power event. In their response to ODI, Kia described that if the threads of a head bolt hole in the subject engine becomes damaged, the clamping force between the cylinder head and engine block can decrease in the area of the affected head bolt. Kia’s assessment of the alleged defect is that when the failure occurs, drivers are provided with numerous warning signs prior to a potential loss of motive power event. According to Kia, potential warning signs associated with this failure include coolant leak/consumption or noticeable coolant odor, engine oil leak/consumption, engine temperature gauge rising to “H” (hot), check engine light illuminating, engine cooling fan remaining on following the engine being shut off, HVAC system not functioning properly, unusual engine noise, difficulty starting the vehicle, and smoke/condensation emitting from the engine compartment or exhaust. Through both its review of the information provided by Kia and outreach to consumers, ODI confirmed that there is reasonable detectability present in the vast majority of occurrences of the alleged defect. To mitigate the alleged defect, Kia increased the engagement depth of the head bolt threads for all subject engines, beginning in May 2017. ODI’s analysis of the failure data demonstrates that this corrective action correlates with a much lower incident report rate for engines produced following the change (8 per 100,000 vehicles for the MY 2018-2020 Kia Sorento). In December 2023, Kia launched extended warranty campaign WTY035 covering failures associated with the alleged defect in the subject vehicle population through 15 years or 180,000 miles, whichever comes first. Through its investigation, ODI identified the following peer vehicle populations, which were produced prior to the corrective action and exhibit failure rates comparable to the subject vehicles: MY 2014-2015 Kia Sorento, MY 2015-2016 Kia Sedona, and MY 2014-2017 Kia Cadenza equipped with the 3.3 L engine. Through discussions with ODI during the investigation, Kia decided to launch extended warranty campaign WTY039 in May 2024, which covers these peer vehicle populations through 15 years or 180,000 miles, whichever comes first. Based on analysis of the failure data indicating a low incident report rate of loss of motive power for the alleged defect, and in consideration of the warning signs which frequently occur from head gasket and/or head bolt failure in the subject engines, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

According to Kia, potential warning signs associated with this failure include coolant leak/consumption or noticeable coolant odor, engine oil leak/consumption, engine temperature gauge rising to “H” (hot), check engine light illuminating, engine cooling fan remaining on following the engine being shut off, HVAC system not functioning properly, unusual engine noise, difficulty starting the vehicle, and smoke/condensation emitting from the engine compartment or exhaust. Through both its review of the information provided by Kia and outreach to consumers, ODI confirmed that there is reasonable detectability present in the vast majority of occurrences of the alleged defect. To mitigate the alleged defect, Kia increased the engagement depth of the head bolt threads for all subject engines, beginning in May 2017. ODI’s analysis of the failure data demonstrates that this corrective action correlates with a much lower incident report rate for engines produced following the change (8 per 100,000 vehicles for the MY 2018-2020 Kia Sorento). In December 2023, Kia launched extended warranty campaign WTY035 covering failures associated with the alleged defect in the subject vehicle population through 15 years or 180,000 miles, whichever comes first. Through its investigation, ODI identified the following peer vehicle populations, which were produced prior to the corrective action and exhibit failure rates comparable to the subject vehicles: MY 2014-2015 Kia Sorento, MY 2015-2016 Kia Sedona, and MY 2014-2017 Kia Cadenza equipped with the 3.3 L engine. Through discussions with ODI during the investigation, Kia decided to launch extended warranty campaign WTY039 in May 2024, which covers these peer vehicle populations through 15 years or 180,000 miles, whichever comes first. Based on analysis of the failure data indicating a low incident report rate of loss of motive power for the alleged defect, and in consideration of the warning signs which frequently occur from head gasket and/or head bolt failure in the subject engines, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.

On November 13, 2023, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE23-019) to investigate allegations of loss of motive power relating to head gasket and/or head bolt failure in Model Year (MY) 2016-2017 Kia Sorento vehicles equipped with the 3.3 L Lambda II engine. When the investigation was opened, ODI had received 13 Vehicle Owner Questionnaires (VOQs) related to reports of loss of motive power. In an information request letter dated November 30, 2023, ODI requested technical information and failure data relating to the alleged defect in the subject MY 2016-2017 Kia Sorento as well as several peer vehicle populations which share the 3.3 L engine. In its February 26, 2024, response to ODI’s information request, Kia provided 2022 customer complaints (including techline and field reports) and 1738 warranty claims representing 2411 unique vehicles within the subject vehicle population. Of the customer complaints provided by Kia, they identified only 53 unique allegations of a loss of motive power resulting from the alleged defect. Kia determined that the remaining reports were minor vehicle drivability or engine performance issues. ODI reviewed the information provided by Kia, along with additional VOQs submitted to NHTSA following the opening of the investigation. When eliminating duplicative reports across the data sources, the total number of allegations of loss of motive power relating to the alleged defect in the subject vehicles is 77, representing an incident report rate of 59 per 100,000 vehicles. The MY 2016 Kia Sorento exhibited both the highest overall complaint rate and loss of motive power report rate across all subject and peer vehicle populations, representing an incident report rate of 102 per 100,000 vehicles. Across all data sources, there are no allegations of crashes or fires relating to the alleged defect. The one injury incident reflected in the failure summary table above is related to a consumer who was reportedly burned (minor burn requiring medical attention) while attempting to remove the coolant reservoir cap following a loss of motive power event. In their response to ODI, Kia described that if the threads of a head bolt hole in the subject engine becomes damaged, the clamping force between the cylinder head and engine block can decrease in the area of the affected head bolt. Kia’s assessment of the alleged defect is that when the failure occurs, drivers are provided with numerous warning signs prior to a potential loss of motive power event. According to Kia, potential warning signs associated with this failure include coolant leak/consumption or noticeable coolant odor, engine oil leak/consumption, engine temperature gauge rising to “H” (hot), check engine light illuminating, engine cooling fan remaining on following the engine being shut off, HVAC system not functioning properly, unusual engine noise, difficulty starting the vehicle, and smoke/condensation emitting from the engine compartment or exhaust.

DP22003 · Loss Of Motive Power

Opened Sep 12, 2022 · Closed Dec 12, 2023

Status: closed (inferred from source dates) · Engine

The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing.  There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling:engine:oil/lubrication:pressure/temperature Sensor

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.
