On June 23rd my 2015 Kia Sorento with a 3.3 l engine V6 started making noises and I called a dealership and they asked if it sounded like knocking noises and I said no it sounded more like exhaust noise within an hour my car was losing power it was idling very rough and I took it into the dealership and they said that I need ed an entire new engine. However I had been in there on June 14th and they told me that my oil level was good and there were no leaks but on June 23rd suddenly I had 0 oil in my engine and they were claiming that it was my issue however it is The exact issue that Kia has had with this model and make but different engine. My car has 91000 miles on it I use full synthetic oil I had it changed 6000 miles ago it was fine then I have had the maintenance done on my car and there were 0 warning lights on my - for either oil or engine that is why I checked electrical I was told by the dealer that there Oil lights and engine lights often don't come on when they have a problem with the car. This is a huge safety issue and if it's starting to happen on the 3.3 engine this needs to be looked at immediately I know someone who owns the exact same year exact same engine and they have been dealing with this type of thing as well

This is a continuing problem. I have previously reported this issue to KIA and it has fallen in silent ears. For whatever reason my vehicle has been bone dry of oil. There is no warning that the oil is low. No indicator comes on., nothing! This can happen immediately after an oil change. The oil does not leak on the ground and it is known where the oil goes. The only way I know that there’s is no oil is that the car smells as though something is burning. I have spent hundreds of dollars in oil trying to keep up with when it dry’s out. Also, the rear brake light (right) burns out at least twice a month. At one point the light burned into the housing unit and had to be pulled out with needle nose pliers. I have again spent a lot of money on replacing bulbs. This car is extremely unsafe and I feel at anytime the car will catch on fire.

KIA MOTOR IS DECLINING TO REPLACE MY MOTOR BASED ON THE PRODUCT IMPROVEMENT CAMPAIGN OF 18V907000 BECAUSE THEY STATE THAT I FAILED TO HAVE THE CAR INSPECTED WITH THIS CAMPAIGN. KIA MOTORS TOLD ME THAT THEY SENT THE PRODUCT IMPROVEMENT CAMPAIGN NOTICE TO THE PREVIOUS OWNER IN 2018 BUT THAT IT WAS STILL MY FAULT THAT THE INSPECTION WAS NOT DONE AND THE KNOCK SENSOR WASN'T ADDED. I LET THEM KNOW I KNEW NOTHING ABOUT THIS BECAUSE I NEVER RECEIVED THE LETTER BECAUSE IT WAS NOT SENT TO ME AND I WAS NOT NOTIFIED AND THE CONSUMER AFFAIRS SUPERVISOR SAID IT WAS STILL MY FAULT FOR NOT CALLING KIA WHEN I PURCHASED THE CAR IN 2015 TO LET THEM KNOW I AM THE NEW OWNER AND TO GIVE THEM MY INFORMATION.

TOOK MY CAR TO THE MECHANIC FOR A SECOND OPINION REGARDING LOW BEAM LIGHTS SHUTTING OFF WHEN I TURN ON THE HIGH BEAMS. THIS OCCURRED FREQUENTLY WHEN USING HIGH BEAMS. ALSO, MY HEADLIGHTS (LOW BEAMS) CONSISTENTLY BURNT OUT. HAD TO INSTALL 2-3 NEW BULBS IN EACH HEADLIGHT (WITHIN 1 YR.). MECHANIC SAID PROBLEM IS MORE THAN JUST THE LIGHTS, THE KNOCK SENSOR WAS BAD AND NEEDED MORE WORK THAN WHAT THEY WERE WILLING TO DO AND RECOMMENDED ME GOING BACK TO KIA. DRIVING HOME FROM MY MECHANIC, I WAS ON THE SURFACE STREETS TO GET ON THE FREEWAY, A KNOCKING NOISE OCCURRED WHEN ACCELERATING, SOUNDED LIKE IT WAS GOING TO THROW A ROD, WHICH LED ME TO CHECK THE OIL. MY OIL CHANGES ARE COMPLETED ON SCHEDULE AND WAS NOT DUE FOR ANOTHER OIL CHANGE FOR 3,000 MILES. THE OIL WAS BONE DRY. I PUT IN 4 QUARTS OF OIL AND DROVE ON SURFACE STREETS, BACK TO MY MECHANIC. MECHANIC SAID IT IS ABOUT TO THROW A ROD AND THAT I NEEDED TO DRIVE IT SLOWLY AND GET IT TO KIA. AS I DROVE THE CAR HOME ON THE FREEWAY, I WAS IN THE NUMBER ONE LANE, PASSING A SEMI-TRUCK IN THE NUMBER TWO LANE, CAR STARTED SHAKING, ALL THE LIGHTS STARTED BLINKING, THE ORANGE STEERING WHEEL WARNING LIGHT WENT ON AND THE ENTIRE CAR COMPLETELY SHUT DOWN. I HAD TO COAST TO THE SHOULDER ON THE FREEWAY. I HAD NO HAZARDS OR BLINKERS. TOW TRUCK ARRIVED AND CHECKED MY OIL, HE SAID THERE WERE METAL SHAVINGS AND BARELY ANY OIL. TOWED THE CAR BACK TO THE MECHANIC AND THEY SAID I NEEDED A NEW ENGINE. HAD THE CAR TOWED TO MY HOME AND IT NOW SITS IN MY DRIVEWAY. PRIOR AND DURING ALL OF THIS, NOT ONE TIME DID ANY WARNING LIGHTS ON THE DASHBOARD GO ON (OTHER THAN THE ONE STEERING WHEEL LIGHT WHEN THE CAR SHUT DOWN).

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

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.

DP21003 · Throttle Control System Vulnerabilities
Opened Nov 12, 2021 · Closed Jun 20, 2023
Status: closed (inferred from source dates) · Vehicle Speed Control:throttle
The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) received a petition letter dated October 10, 2021, requesting an investigation of possible defects in the electronic throttle control (ETC) system on certain Kia vehicles resulting in the opening of DP21-003. Accordingly, Model Year (MY) 2005-2016 Kia Optima/K5, MY 2006-2015 Kia Sorento, MY 2007-2016 Hyundai Elantra, MY 2007-2016 Hyundai Santa Fe, MY 2006-2015 Hyundai Sonatas are all part of the subject population. 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.
