PURCHASED THIS 2015 VEHICLE FROM A REGIONAL PA/NJ RESELLER NAMED CARSENSE IN NOVEMBER 2015 WITH 15,000 MILES. MAINTAINED REGULAR SERVICE AND OIL CHANGES, ALTHOUGH NOT ALWAYS WITH CASTROL OIL, AS REQUIRED FOR THE CARSENSE EXTENDED WARRANTY. DRIVING ON THE HIGHWAY RETURNING FROM THE BEACH WHEN THE ENGINE STARTED A SLIGHT KNOCK WHEN ACCELERATING. STOPPED AND CHECKED THE OIL LEVEL WHICH WAS FINE. JUST AT 3,000 MILES ON THE OIL AT THE TIME. NO CHECK ENGINE LIGHT. DROVE FURTHER AND THE CHECK ENGINE LIGHT CAME ON AND THEN THE ENGINE STALLED. TOWED TO A KIA DEALER AND TOLD ENGINE WAS SEIZED. AS I AM A SECOND OWNER THE 100,000 MILE WARRANTY DID NOT APPLY. VEHICLE WAS 909 MILES OVER THE 60,000 MILE WARRANTY AND NOT COVERED. ESCALATED WITH KIA CONSUMER AFFAIRS WHO I CHASED FOR OVER A WEEK WITH ESCALATION REQUESTS. FINAL ANSWER ... WE ARE SORRY BUT THE CAR IS OUT OF WARRANTY. WOULD NOT OFFER ANY RELIEF ON EITHER PARTS OR LABOR. REPLACING THE ENGINE TO THE TUNE OF $5,400.00 INCLUDING REPLACING A STARTER WHICH MYSTERIOUSLY "BURNED UP". WE HAVE FOUND MANY SIMILAR STORIES WITH ENGINE PROBLEMS THAT ARE MOST LIKELY RELATED TO THE 2012-2014 2.4L ENGINE RECALL.

DRIVING ON A 4 LANE HIGHWAY MY 2015 KIA SORENTO DIED WITHOUT WARNING AND MADE A CLICKING NOISE WHEN I TRIED TO START IT. I HAD THE CAR TOWED TO A LOCAL KIA DEALERSHIP WHO ADVISED METAL SHAVINGS WERE FOUND IN THE OIL, WHICH CLOGGED THE OIL FILTER, RESTRICTING OIL FLOW THUS CAUSING THE CONNECTING ROD BEARINGS TO BREAK. THEY CONFIRMED THERE WAS NO SLUDGE FOUND IN THE ENGINE. THE CAR NEEDS THE ENGINE REPLACED AND MY EXTENDED WARRANTY IS REFUSING TO PAY CITING THERE WAS NOT SUFFICIENT OIL LUBRICATION DUE TO LOW OIL WHICH CAUSED THE CONNECTING ROD BEARINGS TO BREAK. HOWEVER, THE DEALERSHIP ADVISED BOTH MYSELF, WARRANTY, AND ADJUSTER THE CAR WAS BURNING OIL AS NO EXTERNAL ENGINE LEAKS WERE FOUND. ALL OIL CHANGES WERE COMPLETED BY THE KIA DEALERSHIP WHOM I PURCHASED THE CAR FROM AND RECORDS WERE PROVIDED. AT NO POINT DID ANY WARNING LIGHTS ILLUMINATE ON THE DASHBOARD TO INDICATE LOW OIL OR TO CHECK ENGINE. MY 2015 KIA SORENTO HAS THE GDI (OR THETA II) ENGINE WHICH IS NAMED IN MULTIPLE CLASS ACTION LAWSUITS FOR THE SAME THING. I STILL OWE ON THIS CAR AS I HAVE ONLY HAD FOR 1.5 YEARS AND AM NOW LOOKING AT $5,000-$7,000 IN REPAIRS.

WHICH SHOULD NOT BE THECASE WITH A NEWER CAR, AFTER TAKING IT TO THE DEALERSHIP THEY SAID NOTHING WAS WRONG. ADDITIONALLY WHEN I TURN ON THE AIR CONDITIONER IT SMELLS LIKE VINEGAR OR DIRTY SOCKS AN AWEFUL SMELL, ONCE AGAIN THE DEALERSHIP STATED NOTHING WRONG WITH THE CAR. IT SOUNDS LIKE KIA IS COVERING UP OLD DEFICIENCIES WITH THEIR ENGINES AS IT SAID ENGINES MANUFACTURED INTO LATE 2014 WERE RECALLED HOW IS THE 2015 KIA, WHICH WAS MANUFACTURED IN 2014 NOT ON THE RECALL LIST? ADDITIONALLY THERE HAVE BEEN MANY MANY OTHER PEOPLE LISTING THE ENGINE SEIZING UP. MY WIFE DRIVES THIS CAR WITH MY SMALL CHILDREN IM WRITING THIS RETRACTIVELY IN CASE SOMETHING HAPPEN. ADDITIONALLY WE GET REGULAR OIL CHANGES DONE. I THINK THIS ENGINE MODEL SHOULD BE RECALLED. AS A NEWER ENGINE SHOULD DEFINITELY NOT BE BLOWING WHITE SMOKE OUT OF THE EXHAUST NOR TICKING LIKE THE COMPONENTS ARE DISPLACED.

I WAS DRIVING TO WORK YESTERDAY MORNING (7/10/18) ON ROUTE 15 IN SUSSEX COUNTY. MY SPEED WAS APPROXIMATELY 65-70 MILES PER HOUR. I HEARD A KNOCKING SOUND, WHICH ALARMED ME. IT WENT AWAY, AND CAME BACK, OFF AND ON, WHILE DRIVING, A SOUND THAT I HAVE NEVER HEARD BEFORE WITH THIS VEHICLE, EVER. NO LIGHTS CAME ON, NO INDICATORS, ETC. I CONTACTED NEWTON KIA, WHERE THE VEHICLE WAS PURCHASED, AND WAS TOLD THAT THEY COULDN'T FIT ME IN UNTIL FRIDAY. I MADE AN APPOINTMENT, BUT AFTER DOING THIS I DECIDED TO CONTACT ONE CLOSER TO WHERE I WORK, WHICH IS ON RT. 10 IN DENVILLE, NJ. GATEWAY KIA. I BROUGHT THE VEHICLE IN AND HAD THEM CHECK OUT THE NOISE. I WAS CONTACTED AND TOLD THAT IT WAS THE ENGINE, THAT IT WOULD COST $7100.00. THE WAY I WAS NOTIFIED WAS AS IF I HAVE $7100.00 JUST SITTING AROUND, WHICH I DON'T. THE ENGINE, THE ENGINE, NO WARNING, NO NOTHING. I PICKED UP THE VEHICLE, AND DROVE IT HOME, STILL HEARING THE KNOCKING NOISE OFF AND ON. I ATTEMPTED TO GO TO WORK TODAY, 7/11/18. THE NOISE BECAME WORSE ABOUT A BLOCK FROM MY HOME. I TURNED AROUND AND CAME HOME, SHUT THE CAR OFF, SMOKE CAME OUT FROM THE ENGINE AREA. LET ME MAKE SOMETHING VERY CLEAR TO WHOMEVER REVIEWS THIS INFORMATION. I AM NOT PAYING FOR THIS REPAIR, KIA IS. FIRST THING YOU ARE TOLD THAT YOU ARE OVER YOUR WARRANTY. I JUST TURNED 102,000 MILES, HAVE HAD NO PRIOR ISSUES. THIS HAPPENED OUT OF THE BLUE, NO PRIOR NOISE OR PROBLEMS. I AM NOW DRIVING A RENTAL, I NEED TO GET TO WORK, I NEED MY SORENTO FIXED, AND I AM NOT PAYING FOR IT. I AM ALSO GOING TO BE REIMBURSED FOR THIS RENTAL. I, AGAIN, HAVE HAD NO PRIOR ISSUES WITH MY VEHICLE. I AM VERY UPSET ABOUT THIS, SO WHAT IS GOING TO BE DONE ABOUT IT.

MY WIFE WAS DRIVING HOME FROM WORK AND WHILE IN RUSH HOUR TRAFFIC ON THE HIGHWAY TRAVELING APPROXIMATELY 50 MPH THE ENGINE JUST STOPPED. SHE DID NOT RECEIVE ANY WARNING, NO SMOKE COMING FROM THE TAILPIPE, AND NONE OF THE CHECK/OIL LIGHTS CAME ON IN THE DASH. SHE WAS FORTUNATE TO GET IT PULLED OVER TO THE SIDE OF THE ROAD BEFORE IT STOPPED. WHEN I ARRIVED TO SEE WHAT WAS WRONG THERE WASN'T ANY OIL IN THE ENGINE. I HAD JUST CHECKED THE OIL 10 DAYS PRIOR WHILE FILLING UP FOR GAS AND THE OIL WAS FULL. I ADDED OIL AND TRIED STARTING THE CAR AND IT WOULD NOT START. TOWED THE VEHICLE HOME AND DISCOVERED THE BATTERY COMPLETELY DIED. I REPLACE THE BATTERY AND THE ENGINE STARTED BUT I WAS HEARING A CONSTANT TICK-TICK-TICK AND ONCE PUTTING THE CAR IN GEAR THERE WAS A VERY LOUD RATTLE, THEN IT ALMOST DIED. NEXT DAY I CONTACTED KIA TO HAVE IT TOWED TO A LOCAL DEALERSHIP AND THEY OPENED THE ENGINE. THE HEAD MECHANIC TOLD ME THAT IT WAS A SIGN OF LACK OF MAINTENANCE BECAUSE THERE WAS MASSIVE AMOUNTS OF SLUDGE AND KIA WARRANTY WOULD NOT COVER IT. I INFORMED THE MECHANIC THAT I COMPLETE ALL MY OIL CHANGES BUT DON'T SAVE THE RECEIPTS AND COULDN'T PRODUCE THEM. SUGGESTED BY THE MECHANIC TO CALL CONSUMER LINE AND I RECEIVED A BUNCH OF RUN-AROUND AND SAID SINCE I DON'T HAVE MAINTENANCE RECORDS THEY WILL NOT HONOR THEIR WARRANTY. AFTER DETAILED RESEARCH I HAVE FOUND NUMEROUS COMPLAINTS OF EXACTLY THE SAME ISSUE FROM OTHER CONSUMERS THAT OWN A 2015 KIA SORENTO AS WELL, INCLUDING THIS SITE. I BELIEVE A COMPLETE RECALL IS IN ORDER FOR ALL 2015 KIA SORENTO'S FOR ENGINE TROUBLE AND KIA NEEDS TO HONOR THEIR WARRANTY!

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.
DP21002 · Engine Oil Pressure Switch Leak
Opened Nov 12, 2021 · Closed Jun 26, 2023
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.

The petition was originally filed as a Vehicle Owner Questionnaire that can be reviewed at NHTSA.gov under reference (ODI) number 11439675.On November 12, 2021, ODI opened Defect Petition DP21-003 to evaluate the petitioner?s request. ODI performed trend analyses of the VOQs related to vehicle speed control issues for all the subject vehicles and found that none of the 52 Model/Model Year Hyundai/Kia vehicles demonstrated any actionable trend that warranted an investigation.Petitioners submitted 1119 VOQs and non-VOQ cases in which sudden uncommanded acceleration (SUA) or loss of motive power (LOMP) incidents were alleged.For the 1119 reports, 220 were incidents involving crashes, from which 69 subject Hyundai-Kia vehicles were inspected by Hyundai/Kia dealer technicians, Hyundai/Kia engineers, and/or third-party representatives.ODI found the inspections identified no vehicle defects related to the ETC system.Of the 220 crash-involved reports, 13 Event Data Recorder (EDR) records were downloaded successfully and 11 of those indicated driver error: (i.e.) pedal misapplication.A condition where the accelerator pedal is mistakenly applied instead of the brake pedal when the driver wants to stop the vehicle.In addition, ODI reviewed a scientific journal paper published in Forensic Science International in 2016 by Mr. Park et al ., as well as related test videos. ODI does not believe there is any evidence of uncontrollable SUA occurrences in any of the tests reviewed. NHTSA's Office of Vehicle Safety Compliance (OVSC) reviewed the allegations regarding the potential noncompliance with Federal Motor Vehicle Safety Standard No. 124.Based on the information provided, the Agency concludes there is insufficient information for us to determine if a possible non-compliance exists.Finally, both Hyundai and Kia informed ODI that all their vehicles manufactured after 2012 were equipped with an ETC management system, in which the engine speed will go to idle when the system sees signals from both the brake pedal and accelerator pedal at the same time; this is commonly known as the brake-throttle override system.After thoroughly assessing the material submitted by the petitioner, information already in NHTSA's possession, information submitted by Hyundai and Kia in response to an Information Request letter, and the potential risks to safety implicated by the petitioner's allegation, NHTSA does not believe that a formal investigation is warranted. After full consideration of appropriate factors, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA?s reasons for denial of the petition will be published.
