I am filing this complaint regarding a serious engine issue with my 2006 Hyundai Sonata equipped with a 2.4L GDI engine. My vehicle experienced [engine knocking, stalling, and then seized up indicating complete Engine failure] without warning, posing a potential safety hazard while driving. The issue appears to be identical to the known manufacturing defects that Hyundai has acknowledged in its recall of 2013–2014 Sonata models with the same engine Class Type. Although my vehicle is not currently included in the official recall “ SONATA ENGINE RECALL CAMPAIGN it contains the Theta II MPI Engine which constitutes and Further solidifies proof of the ongoing Manufacturing Defects of Theta Model Engine design and exhibits the same symptoms of sudden engine failure. This raises concerns that the defect may affect a broader range of model years than Hyundai has acknowledged. I urge NHTSA to investigate this issue and determine whether the scope of the current recall should be expanded to include earlier model years such as 2006. The defect creates a significant safety risk to drivers and passengers, and Hyundai should be held accountable for all affected vehicles—not just those produced within a narrow window.

FIRST OF ALL THE TIME AND MILEAGE ARE APPROXIMATE. WE EXPERIENCED DIFFICULTY IN TURNING OFF THE PARKING/DASHBOARD LIGHTS IN OUR 2006 HYUNDAI SONATA. FLICKING THE STALK BACK AND FORTH A FEW TIMES WOULD EVENTUALLY TURN THEM OFF. I ASKED MY MECHANIC AND CALLED 2 LOCAL HYUNDAI DEALERS AND ALL AGREED THE ONLY SOLUTION IS TO REPLACE THE ENTIRE FUSE/RELAY BOX. AFTER CONSULTING A FEW HYUNDAI FORUMS I LEARNED THAT THIS WAS A PROBLEM AFFECTING SOME 2006 AND 2007 HYUNDIAS AND THAT OWNERS WERE PAYING BETWEEN $700 TO $1200 TO REPLACE THE FAULTY PART. MANY OWNERS ARE UPSET THAT HYUNDAI DOES NOT ISSUE A RECALL. ON MONDAY, JANUARY 27, 2014 THE STALK STOPPED WORKING. A CALL TO HYUNDAI NORTH AMERICA NOT ONLY RESULTED IN NO HELP IN FINDING OUT WHICH FUSE WOULD DISABLE THE LIGHTS BUT ALSO ASSURED ME THAT HYUNDAI SEEMS TO EXPECT THE LIFE OF SUCH PARTS TO LAST JUST PAST THE WARRANTY EXPIRATION DATE. I DECIDED TO PULL OUT THE RELAY LOCATED UNDER THE DASHBOARD WHICH TURNED OFF THE LIGHTS (AMONG OTHER THINGS). THE NEXT DAY WHEN MY WIFE LEFT WORK AFTER INSERTING THE RELAY BACK IN, SHE COULDN'T GET OUT OF FIRST GEAR AND SLOWLY THINGS STARTED TO STOP WORKING SUCH AS THE HEATED SEAT AND THE REAR DEFOGGER. ONCE HOME, I DISCONNECTED THE BATTERY, WAITED A FEW MINUTES, RECONNECTED THE BATTERY AND ROAD-TESTED THE CAR. EVERYTHING WORKED NORMAL; HOWEVER, THIS IS THE ONLY WAY TO TURN OFF THE LIGHTS. ON SUNDAY, FEBRUARY 2, 2014 I BOUGHT A BATTERY QUICK-DISCONNECT AND WIRED THE OTHER END TO THE EXISTING HYUNDAI POSITIVE BATTERY CABLE. NOW, WHILE WE WAIT WEEKS (POSSIBLY MONTHS) TO HAVE THE MONEY TO GET THIS PART REPLACED, MY WIFE WILL HAVE TO LEAVE WORK AND IN A DARK PARKING LOT, RECONNECT THE BATTERY USING THIS QUICK-DISCONNECT TOOL.

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.

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.

PE14023 · Seat Belt Buckle Electrical Malfunction

Opened Jul 22, 2014 · Closed Dec 1, 2014

Status: closed (inferred from source dates) · Air Bags; Seat Belts; Seat Belts:front:buckle Assembly

On July 22, 2014 the Office of Defects Investigation (ODI) opened a preliminary evaluation to further analyze allegations of seat belt pretensioner malfunctions on model year (MY) 2006-2008 Hyundai Sonata vehicles.ODI received 131 unique reports alleging a failure within the seat belt pretensioner system, which was typically preceded by SRS light illumination.ODI requested more information from Hyundai in order to understand the nature of the failure and how the airbag deployment algorithm, the seat belt pretensioners, and/or the airbag function may be affected. In response to ODI?s information request (IR), Hyundai submitted 764 unique consumer and field reports and 19,847 warranty claims related to a failure in the front seat belt buckle assembly potentially causing a malfunction of the seat belt pretensioners.In it's response, Hyundai advised that if the resistance specifications for the seat belt buckle pretensioner circuit, located in the seat belt stalk, exceed the nominal range, a diagnostic trouble code will be set and the SRS warning indicator lamp will illuminate.The presence of this stored code will not affect the ability of the SRS Control Module (SRSCM) to detect a collision and command deployment of the pretensioners and airbags, if warranted.In fact, the wiring harness connector may be unplugged from the seat belt buckle pretensioner, and the signal to deploy the pretensioner will still be commanded and recorded.MY 2006-2008 Sonata?s utilize a dual pretensioner system by incorporating pretensioners into both the driver and front passenger seat belt retractor and the seat belt buckle assembly.The retractor pretensioner is located inside the B-pillar and winds (pretensions) the seat belt webbing back into the retractor housing during a collision, helping to remove seat belt slack and restrain the upper torso and hips.In contrast, the buckle pretensioner is located within the stalk of the seat belt assembly and acts to supplement lower limb protection.Both pretensioners are controlled by the SRSCM but utilize separate wiring and connectors.The seat belt retractor pretensioner circuitry and operation is independent of the seat belt buckle pretensioner connector and circuitry.Hyundai produced analysis indicating that increased resistance in the seat belt pretensioner which occurs in vehicle service does not result in a loss of buckle pretensioner.Hyundai further advised that in the unlikely event that a seat belt buckle pretensioner may not deploy due to increased resistance, the retractor pretensioner would still activate.Hyundai advised that the subject vehicles maintain their 5 STAR NHTSA safety rating using the retractor based pretensioner only.ODI notes that MY 2009-10 Sonatas reverted back to a single pretensioner system, and do not utilize seat belt buckle pretensioners. Hyundai advised its intention to initiate a warranty extension program to address concerns with the seat belt buckle prentensioner faults in MY 2006-2008 Hyundai Sonata vehicles.This action will extend the warranty coverage for this issue for 15 years or 250,000 miles, whichever occurs first.Given Hyundai's action and the minimal safety consequence this issue presents, further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor the issue and reserves the right to take further action if warranted by the circumstances.

In response to ODI?s information request (IR), Hyundai submitted 764 unique consumer and field reports and 19,847 warranty claims related to a failure in the front seat belt buckle assembly potentially causing a malfunction of the seat belt pretensioners.In it's response, Hyundai advised that if the resistance specifications for the seat belt buckle pretensioner circuit, located in the seat belt stalk, exceed the nominal range, a diagnostic trouble code will be set and the SRS warning indicator lamp will illuminate.The presence of this stored code will not affect the ability of the SRS Control Module (SRSCM) to detect a collision and command deployment of the pretensioners and airbags, if warranted.In fact, the wiring harness connector may be unplugged from the seat belt buckle pretensioner, and the signal to deploy the pretensioner will still be commanded and recorded.MY 2006-2008 Sonata?s utilize a dual pretensioner system by incorporating pretensioners into both the driver and front passenger seat belt retractor and the seat belt buckle assembly.The retractor pretensioner is located inside the B-pillar and winds (pretensions) the seat belt webbing back into the retractor housing during a collision, helping to remove seat belt slack and restrain the upper torso and hips.In contrast, the buckle pretensioner is located within the stalk of the seat belt assembly and acts to supplement lower limb protection.Both pretensioners are controlled by the SRSCM but utilize separate wiring and connectors.The seat belt retractor pretensioner circuitry and operation is independent of the seat belt buckle pretensioner connector and circuitry.Hyundai produced analysis indicating that increased resistance in the seat belt pretensioner which occurs in vehicle service does not result in a loss of buckle pretensioner.Hyundai further advised that in the unlikely event that a seat belt buckle pretensioner may not deploy due to increased resistance, the retractor pretensioner would still activate.Hyundai advised that the subject vehicles maintain their 5 STAR NHTSA safety rating using the retractor based pretensioner only.ODI notes that MY 2009-10 Sonatas reverted back to a single pretensioner system, and do not utilize seat belt buckle pretensioners. Hyundai advised its intention to initiate a warranty extension program to address concerns with the seat belt buckle prentensioner faults in MY 2006-2008 Hyundai Sonata vehicles.This action will extend the warranty coverage for this issue for 15 years or 250,000 miles, whichever occurs first.Given Hyundai's action and the minimal safety consequence this issue presents, further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor the issue and reserves the right to take further action if warranted by the circumstances.

Status: closed (inferred from source dates) · Suspension:rear

In a letter dated August 9, 2013, Hyundai-Kia America Technical Center, Inc. (Hyundai) notified NHTSA that Hyundaiis conducting a safety recall (13V-354) involving approximately 239,000 vehicles involving model year (MY) 2006 through 2010 Hyundai Sonata vehicles (approximately 215,000)produced beginning on March 1, 2005 through January 21, 2010 and model year (MY) 2006 through 2011 Hyundai Azera vehicles (approximately 24,000) produced beginning on September 27, 2005 through November 22, 2010 that are registered in and operated or originally sold in the following 20 salt belt states and the District of Columbia: Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin.Hyundai will also inform dealers to inspect/repair vehicles that were previously registered in salt belt states but are currently registered elsewhere. Hyundai is conducting the recall to remedy a defect involving internal corrosion of the rear sub frame that may lead to separation of the rear upper/lower control arm(s) at their respective mounting points and/or separation of the axle from the transaxle where they meet.This could result in a loss of vehicle control and/or vehicle disablement which may increase the risk of a vehicle crash.In response to NHTSA?s Information Request (IR) letter, Hyundai stated the Azera vehicles utilizes the identical cross member and upper/lower rear control arm components as the subject (Sonata) vehicles.In analysis of both Vehicle Owner Questionnaire (VOQ) data submitted to the Office of Defects Investigation (ODI) and consumer complaint data submitted to Hyundai, ODI identified 19 non-duplicative reports alleging excessive corrosion of the rear sub frame. All of the complaint vehicles were either originally sold or registered at the time of the incident in one of the salt belt states.Of these 19 reports, 9 alleged either a suspension component separation or a fracture of the vehicle's rear cross member assembly.Similarly, ODI identified 8 warranty claims of rear sub frame replacement in data submitted by Hyundai due to excessive corrosion, all of which involved vehicles originally sold or operated in a salt belt state. Based on Hyundai's decision to conduct a safety recall, (13V-354) this investigation is closed.The VOQs cited above can be viewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification numbers: 10535115, 10534110, 10525976, 10524726, 10521520, 10508368, 10505463, 10490073, 10486752, 10486435, 1048354, 10473922, and 10437887.
