ENGINE IS SEVERELY SLUGGED AND THERE WAS NO WARNING EVER. FOUND OUT AFTER AN OIL CHANGED AT 67K AT JIFFY LUBE WHEN I TOOK IT TO THE OURISMAN KIA DEALER IN CHANTILLY, VA. THERE IS NO WARNING THAT ANY OF THIS SITUATION WAS STARTING TO HAPPEN EVEN AFTER A PREVIOUS OIL CHANGE AT KIA DEALER AT 58K MILES. THE DEALERSHIP DENIED MY CLAIM WITH THE 100K MILE WARRANTY BECAUSE I DON'T HAVE PROOF THAT I DID ALL 9 OIL CHANGES. THEY PROCEEDED TO TELL ME THAT I NEED A NEW ENGINE BUT THAT THEY ARE ON BACKORDER NATIONWIDE AND WHO KNOWS WHAT DATE TBD THAT WILL BECOME AVAILABLE. THE REPAIR SHOP I TOOK IT TO PIEDOMONT IN HAYMARKET, VA SAYS THEY THINK IT IS SOMETHING LIKE A YEAR BEFORE IT MIGHT BE AVAILABLE. SO IN THE MEAN TIME NO LOANER WAS EVER OFFERED TO ME AND NO I HAVE A UNUSABLE VEHICLE THAT I HAVE SUBMITTED A CLAIM FOR WITH GEICO. I DO NOT HAVE FUNDING FOR A NEW ENGINE AND THE FACT THAT THE KIA MOTOR COMPANY HAS NO ENGINE TO EVEN SUPPLY TO ME IS COMPLETELY UNACCEPTABLE PRACTICE FOR A BUSINESS. ALSO 1 YEAR AGO MY BATTERY JUST DIED ACCORDING TO THE KIA DEALER DUE TO A PARASITIC DRAIN. THAT SEEMS SUSPICIOUS TO ME SINCE THE VEHICLE WAS ONLY A YEAR OLD AND HAD TO BE REPLACED WITH ONE I BOUGHT AT WALMART. ALSO, THE FUSE FOR THE DRIVER SEAT CONTINUOUSLY BLOWS.

HAD RECALL FOR PI1802 KNOCK SENSOR UPDATE. 2 WEEKS LATER WENT TO GET UP TO SPEED ON HIGHWAY AND WENT INTO LIMP MODE. TOLD ENGINE NEEDED TO BE REPLACED. WAIT A MONTH AND PICK UP CAR. TURNS OUT ONLY WIRING HARNESS WAS REPLACED. ANOTHER FEW WEEKS AND I GO TO GET ON ANOTHER HIGHWAY IN FAST LANE AND IT HAPPENS AGAIN - LIMP MODE. TOLD ENGINE NOT REPLACED, NOW IT WILL BE AND WITHOUT THE CAR AGAIN AND ENGINE BACK ORDERED. DO NOT QUALIFY FOR LEMON LAW - 2 YEARS AND UNDER 11,000 MILES. HOW DOES SHUTTING DOWN THE ENGINE TO SAVE THE ENGINE BE OF HIGHER CONCERN THAN THE PASSENGERS IN THE VEHICLE???? NOT HAPPY AND NOT MUCH I CAN DO SINCE LEASE. IF AND WHEN I GET IT BACK ITS BEING TRADED - I REFUSE TO SIT IN IT AGAIN.

I HAVE NO CLUE HOW LONG IT WAS WITHOUT OIL AND HAVE NEVER SMELT OIL BURNING UNTIL LAST NIGHT TO WHICH I TOOK IT GET SERVICED FIRST THING THIS MORNING AND PAID OUT OF POCKET WHEN I HAVE AN AGREEMENT WITH THE DEALERSHIP THAT WE PAID EXTRA FOR TO HAVE THEM SERVICE THE VEHICLE AT NO COST WHEN I GO!!! WE TAKE CARE OF OUR VEHICLES IF I FEEL IT IS TOO LONG BEFORE KIA DEALERSHIP CAN SERVICE THE VEHICLE I HAVE PAID IN PAST AND ALWAYS USED THE VALVOLINE EXPRESS CARE AS THAT IS WHERE I TAKE ALL MY OTHER VEHICLES. PLEASE SEE THE SERVICE COMMENTS ON THE ATTACHED INVOICE FROM TODAY'S SERVICE. MY ENGINE COULD HAVE DAMAGE OR EVEN BLOWN FROM THIS!!! THERE WAS NO INDICATION THAT IT WAS LEAKING OIL ON THE SKID PLATE SO EITHER THE DEALERSHIP DID NOT PUT ANY OIL IN THE VEHICLE AT MY LAST OIL CHANGE OR THERE IS SOMETHING GOING ON WITH MY ENGINE!!

ON 3/24/2019, OUR 2017 KIA SORRENTO WITH 30K MILES ON COMPLETELY SHUT DOWN ON THE FREEWAY. ALL LIGHTS WENT ON AND OFF, THE CAR SHOOK FROM SIDE TO SIDE AND THE CAR SHUT DOWN WE LOST STEERING AND POWER BRAKES WHILE WE WERE GOING 70MPH ON THE FREEWAY. LUCKILY WE WERE ABLE TO GET TO THE SIDE OF THE FREEWAY. THIS HAPPENED 2 MORE TIMES AND THEN WE HAD THE CAR TOWED TO A DEALERSHIP FOR SERVICE. THIS COULD HAVE EASILY CAUSED A LIFE THREATENING CAR ACCIDENT AND WE NO LONGER FEEL SAFE DRIVING THIS KIA. NOW THE SERVICE DEALER IS NOT ABLE TO REPLICATE THIS INCIDENT WHICH HAS HAPPENED TO OTHERS WE ARE READING ABOUT SO THEN THE DEALERSHIP SAYS, "NO ISSUE." THIS CAR HAS BEEN RECALLED FOR THIS EXACT ISSUE (ALTHOUGH NOT OUR VIN APPARENTLY). THIS IS OUR FIRST AND LAST EXPERIENCE WITH THE KIA - VERY DISAPPOINTING. WE BOUGHT THE TOP OF THE LINE KIA BECAUSE IT WAS RATED SO HIGHLY FOR SAFETY BUT NOW WE ARE NOT EVEN COMFORTABLE DRIVING IT. MY CHILDREN WERE IN THE CAR AND LIVES COULD HAVE BEEN LOST.

FEB. 2ND 2019 MY 2017 KIA SORENTO STALLED TWICE IN THE DRIVEWAY. MY HUSBAND TOOK IT FOR A DRIVE AND IT MADE A LOUD NOISE UPON ACCELERATION. HE SUSPECTED IT WAS THE ENGINE AND IT WAS TOWED TO THE DEALER FEB 3RD. FEB 5TH THE SERVICE DEPARTMENT FINALLY CALLED AND SAID THE ENGINE FAILED AND WE WILL NEED A REPLACEMENT. HE STATED SINCE MY HUSBAND DID THE OIL CHANGES AND DID NOT HAVE DOCUMENTATION IT WOULD NOT BE COVERED UNDER WARRANTY. MY HUSBAND ALWAYS DID OUR OIL CHANGES AND NEVER HAD THIS PROBLEM. AN ENGINE SHOULD NOT FAIL IN LESS THAN 2 YEARS AND I REALIZE THIS IS HAPPENING TO MANY KIAS. WE LEARNED OUR LESSON THE HARD WAY AND WILL BE PAYING OUT OF POCKET FOR REPAIRS. MY CAR HAS BEEN IN THE SHOP FOR 2 WEEKS NOW. THERE IS NO ENGINES AVAILABLE IN THE US AND MAYBE THEY CAN GET ONE FROM KOREA BUT SHIPPING TAKES A WEEK ONCE THEY FIND ONE AND THE WORK WILL TAKE A WEEK. SO I'M PAYING FOR A CAR I CAN'T DRIVE FOR AT LEAST 4 WEEKS. SO FRUSTRATING. I CALLED THE SERVICE DEPARTMENT FEB 15TH TO CHECK ON THE STATUS OF FINDING AN ENGINE FOR MY SORENTO, HE STATED HE WOULD CHECK WITH THE PARTS DEPARTMENT AND CALL ME BACK ASAP. STILL WAITING.

3PE23019 · 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.

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. 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.

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.

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.
