TL* THE CONTACT OWNS A 2014 KIA OPTIMA HYBRID. WHILE DRIVING VARIOUS SPEEDS, THE CHECK ENGINE, HEV, TIRE PRESSURE MONITORING, AND OIL CHANGE WARNING INDICATORS ILLUMINATED. IN ADDITION, THE ENGINE STALLED. THE CONTACT PULLED THE VEHICLE OVER TO THE SIDE OF THE ROAD. THE VEHICLE WAS TOWED TO THE DEALER (FRED ANDERSON KIA OF RALEIGH LOCATED AT 9209 GLENWOOD AVE, RALEIGH, NC 27617; (919) 785-4500). THE DEALER RECALIBRATED THE HYBRID ELECTRIC STARTER GENERATOR. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED FOUR OTHER TIMES. THE VEHICLE WAS TAKEN TO THE SAME DEALER ALL EACH TIME WHERE THEY RECALIBRATED THE CHARGING SYSTEM. LATER, WHEN THE VEHICLE WAS TAKEN BACK TO THE DEALER, THE ENTIRE HYBRID SYSTEM NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED AND THE FAILURE RECURRED. THE VEHICLE WAS TAKEN TO THE SAME DEALER. THE VEHICLE WAS STILL NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS CONTACTED AT 800-333-4542 AND STATED THAT THERE WAS A SEALED CRACK IN THE HYBRID BATTERY WHERE THE COOLANT WAS HELD. THE FAILURE MILEAGE WAS 31,885.

I WAS DRIVING ON A FOUR LANE HIGHWAY WITH MY 4 YR OLD AND 7 YR OLD. LITERALLY AS I PULLED OFF ONTO THE OFF RAMP, MY DASH LIT UP STATING "HYBRID SYSTEM NOT CHARGED. PULL OFF AND TURN OFF ENGINE" I DID NOT EVEN HAVE TIME TO DO THIS WHEN THE ENGINE SHUT OFF IN AN EXTREMELY DANGEROUS PLACE. IF THIS HAD HAPPENED WHILE DRIVING ON THE HIGHWAY, WE COULD HAVE BEEN KILLED. AFTER HOURS SPENT HAVING TO CONVINCE THE DEALERSHIP TO TOW THE VEHICLE AND PROVIDE A RIDE FOR ME AND MY CHILDREN, WE FINALLY WERE ABLE TO GET A RENTAL. KIA SAID THE HYBRID BATTERY DIED BUT IT IS ON BACK ORDER AND NOT AVAILABLE IN THE UNITED STATES UNTIL OCTOBER (3 MONTHS FROM NOW). HMMMM SOMETHING SOUNDS FISHY TO ME. I WILL NEVER DRIVE A KIA AGAIN. THE WHOLE ORDEAL WAS TRAUMATIZING TO MY CHILDREN AND WE WERE MADE TO FEEL LIKE WE WERE THE ONES AT FAULT.

I WAS AT A STOP LIGHT WAITING MY TURN, THE LIGHT TURNED GREEN, AND I TOOK MY FOOT OFF THE BRAKE TO PUT IT ON THE GAS. AS I PRESSED THE GAS MY CAR STARTED TO SHAKE, NO ACCELERATION, AND MY DASH LIT UP STATING "HYBRID SYSTEM NOT CHARGED PULL OVER AND TURN OFF ENGINE" I TURNED OFF MY CAR, TRIED TO RESTART IT AND IT STATED THAT MY HEV SYSTEM (HYBRID ELECTRIC VEHICLE SYSTEM) HAS FAILED. I LUCKILY WAS BESIDE A GAS STATION AND I THREW IT INTO NEUTRAL AND WAS ABLE TO PUSH IT JUST INTO THE PARKING SECTION. I HAD TO HAVE MY CAR TOWED TO THE NEAREST DEALER TO HAVE IT CHECKED OUT. DURING THE DRIVE MY BATTERY COMPLETELY DIED SO BY THE TIME I GOT THERE IT HAD NO POWER. CHANGED OUT THE BATTERY AND SAFETY SWITCH WHICH HAD SEEMED TO FAIL. (OF COURSE NOT UNDER WARRANTY). AFTER SPENDING $1,000 ON REPAIRS/LABOR THE CAR STILL WILL NOT TURN ON AND THE ENGINE SEEMS TO SEIZE. AFTER A LITTLE DIGGING MY VIN ISNT ELIGIBLE FOR A RECALL, THOUGH THE 2014 KIA OPTIMA IS FOR THE SAME EXACT ISSUE. HOPEFULLY KIA WILL BE ABLE TO FIGURE OUT WHATS WRONG BECAUSE I REALLY DO LIKE THIS CAR BUT A FAILING ENGINE WONT GET ME ANYWHERE!

I WAS DRIVING DOWN A CITY STREET (35MPH) WHEN I WAS CUT OFF BY ANOTHER CAR MAKING A TURN IN FRONT OF ME AND WE COLLIDED. I T-BONED HIS CAR AND MY AIR BAGS DIDNT GOT OFF. MY CAR STALLED COMPLETELY AND NOTHING ABOUT THE VEHICLE SAFETY EQUIPMENT REACTED TO THE CRASH. THE SYSTEM (CLUSTER AND SCREEN) DIDNT SHOW THAT THERE HAD BEEN ANY IMPACT AND THE CAR WAS READY TO DRIVE. I REPORTED THIS TO KIA OF DOWNTOWN LA (THE DEALER) AND KIAUSA CORPORATE WHERE THEY OFFERED TO CHECK THE CAR OUT AND SEE IF THE CAR REACTED THE WAY IT WAS SUPPOSE TO. AT THE END OF THEIR INSPECTION THEY CLAIMED THAT MY CAR DID WHAT IT WAS SUPPOSE TO AND DIDNT DEPLOY THE AIRBAGS AS THE CAR DETERMINED THAT IS DIDNT NEED TO. I ASKED WHY DIDNT THE CAR SHOW ANYWHERE THAT THERE WAS IMPACT AND IF THE SENSORS EVEN DETECTED ANYTHING AS THERE WAS NO MESSAGED ANYWHERE. THEY CLAIM IT DOESNT SUPPOSE TO. A FEW WEEKS AFTER IT WAS REPAIRED I STARTED GETTING MESSAGES IN THE CLUSTER "CHECK AIR FLAP SYSTEM". TOOK IT BACK AND FOURTH TO THE DEALER WHERE I FINALLY OPENED A BBB CLAIM. IN MY CLAIM I ALSO REPORTED A DELAY REACTION WHEN ACCELERATING AND WAS TOLD THAT HYBRIDS WORK THAT WAY AND THE RESPONSE TIME IS SLOWER THAN REGULAR GAS CARS. THE PROBLEM IS WHEN TURNING AFTER A COMPLETE STOP THE CAR DOESNT MOVE FOR A FEW SECONDS AND THEN TAKES OFF. OCCASIONALLY, THE CAR WONT TURN OFF, AND ASKS ME TO SHIFT TO P (PARK) WHEN IT IS IN PARK. WHEN THAT HAPPENS I AM FORCED TO TAKE IT TO THE DEALERSHIP WHERE THEY HAVE TO "RESET" THE CAR TO FORCE IT TO TURN OFF (NO ACTUAL SOLUTION BUT TO UNPLUG THE BATTERY AND PLUG IT BACK IN IS WHAT THEY DO) ACCORDING TO KIA I CANT PROVE THAT THE AIRBAGS DONT WORK AS I AM NOT AN EXPERT AND SAME WITH THE DRIVE TRAIN. UNFORTUNATELY THE ONLY WAY OF FINDING OUT IS IF THIS CAR IS INVOLVED IN ANOTHER ACCIDENT. THANK YOU FOR YOUR TIME.

ON THE HIGHWAY AT APPROXIMATELY 60MPG, ENGINE STARTED KNOCKING AS ACCELERATION INCREASED. THEN ACCELERATION WOULD NOT INCREASE AND THE CAR HOVERED AT 60MPH. AFTER A FEW MINUTES AND THE KNOCKING CONTINUING, THE CAR DECREASED TO 40 MPH. THEN THE WARNING CAME ON AND SAID "HYBRID SYSTEM NOT CHARGED PULL OVER AND TURN OFF ENGINE". THEN I PULLED OFF TURNED OFF THE CAR AND ATTEMPTED TO RESTART IT. IT CONTINUED TO PRESENT WITH THE SAME WARNING. NO ENERGY FLOW THROUGH THE ENGINE. I HAD MY CAR TOWED TO MY HOME. I NOTICED RECALLS FOR MY EXACT VEHICLE WITH DIFFERENT VIN #'S AND DESCRIBING THE EXACT SAME ISSUES. A FRIEND OF MINE SENT ME A COPY OF A RECALL NOTICE AFTER I DESCRIBED WHAT OCCURRED AND IT IS ALL THE SAME THINGS THEY DESCRIBE. KIA SAYS MY VIN# IS NOT ON THE RECALL LIST. KIA REFUSES TO FIX THE ISSUE EVEN THOUGH IT IS UNDER 60,000 MILE WARRANTY, CLAIMING THE PROBLEM IS DUE TO MAINTENANCE. I PURCHASED THE CAR IN JANUARY 2017 AND IT IS NOW ONLY APRIL 2017. A WHOLE THREE MONTHS. A CAR I JUST PURCHASED SHOULD NOT HAVE THESE ISSUES.

DP22005 · Pedestrian Alert Sounds

Opened Jan 27, 2023 · Closed Aug 7, 2023

Status: closed (inferred from source dates) · Electrical System:propulsion System

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

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.

EA19001 · Electrical Overstress

Opened Apr 19, 2019 · Closed Sep 19, 2024

Status: closed (inferred from source dates) · Air Bags: Air Bag/restraint Control Module

The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect. During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW. The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications. The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal, firing commands (i.e., when to deploy the airbag(s) and/or pretensioners), and fault information (e.g., diagnostic trouble codes). In September 2016, FCA announced recall 16V-668 for certain model year (MY) 2010 to 2014 Chrysler, Dodge and Jeep products manufactured with the subject ZF-TRW ACU. In this recall, FCA discussed an EOS condition that resulted in a failure of the subject DS84 ASIC, which caused air bag non-deployment. FCA noted that the defect condition had only been observed in vehicles equipped with sensor harnessing routed across the front of the vehicle. Other FCA vehicles that also used the subject ACU, but were not equipped with cross-car harnessing, had not experienced EOS failures, despite similar time in service. During the course of this investigation, ODI sent two separate Information Request (IR) letters to six vehicle manufactures (including FCA, Hyundai, Honda, Kia, Mitsubishi, and Toyota) and one IR letter to ZF-TRW. These IR letters resulted in ODI receiving comprehensive data from these manufacturers and suppliers. Studies of this data found that the DS84 ASIC does not have sufficient protection against negative electrical transients or electrical overstress (“EOS”) that can be generated in certain severe crashes. An electrical transient occurs when the electrical power supplied to a circuit changes momentarily over a short duration of time. In these severe crash cases, the crash sensors and other powered wiring can be damaged and short circuited so as to create a negative electrical transient of sufficient intensity and duration (that are outside the vehicle manufacturer's specification) to damage the ASIC before the restraint device deployment signal is received by the SRS ECU. This damaged signal can lead to incomplete or nondeployment of the air bags and/or pretensioners. Airbag non-deployment and/or lack of pretensioner operation can increase the risk or severity of injury in a crash.A total of 8 fatalities and 14 injuries were associated with known EOS events. The common element in all investigated manufacturers vehicles is the SRS ECU containing a DS84 ASIC manufactured by ZF-TRW. The risk associated with the ASIC is equally shared among all OEMS involved in the investigation. The actual real-world risk can be mitigated by other factors which were assessed by ODI during this investigation. The first mitigating factor involves protections built into the ACU design which protect the DS84 ASIC from damage. There are multiple strategies and levels of protection employed by different OEMs that provide effective EOS mitigation. The two most common strategies at the ACU level are circuit protection diodes on the remote senor signal lines, and current limiting resistors that protect critical components. The second mitigating factor is found at the vehicle level and involves the location and routing of the wires leading from the crash sensors to the SRS ECU. If the wires are well protected in a crash and are not routed with other power wires carrying large currents, the risk for an EOS event is significantly reduced or eliminated. These design specific factors combine to produce a spectrum of risk for the vehicles equipped with ACUs using the DS84 ASIC. Given the many of years of field exposure, it is possible to divide the subject population into two groups; vehicles which have experienced EOS events, and vehicles which have not experienced EOS field events. Four of the six OEMs involved in this investigation have experienced EOS field events on at least one of their models equipped with a DS84 ASIC. All vehicle models (including the Toyota models identified in the Failure Report Summary of the opening resume for this investigation) with field events have been recalled. In an abundance of caution, ODI kept this investigation open five years to monitor field performance and did not identify any field events on vehicles not included in existing safety recalls. Given the spectrum of risk identified in this investigation and that all vehicles with a demonstrated unreasonable risk have been recalled, ODI is closing this investigation. ODI is closing this investigation with the following manufacturer safety recalls: 16V-668, 18E-043, 18V-137, 18V-363, and 20V-024. With the recall actions taken by the subject vehicle and equipment manufacturers, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exists on other model or model year vehicles outside of the recall scopes. The agency reserves the right to take further action if warranted by the circumstances.

In a letter dated June 11, 2018, the Center for Auto Safety (CAS) petitioned the National Highway Traffic Safety Administration (NHTSA) to initiate a safety defect investigation into non-collision related fires on model year (MY) 2011-2014 Kia Optima and Sorento, and Hyundai Sonata and Santa Fe vehicles. In a letter dated July 24, 2018, CAS requested that MY 2010-2015 Kia Soul vehicles be added to the petition. CAS stated that there is a higher number of complaints to NHTSA regarding non-crash fires on these vehicles compared to other similar vehicles. The Office of Defects Investigation (ODI) had already opened Recall Queries (RQ17-003 and RQ17-004) on all Kia and Hyundai vehicles equipped with Theta II engines for engine failures that may cause stalling and fires.The queries cover most of the petition subject Optima, Sorento, Sonata, and Santa Fe vehicles but not any of the subject Soul vehicles.On August 21, 2018, ODI opened a Defect Petition (DP18-003) to evaluate whether to grant or deny the CAS petition. ODI sent Information Request letters to Kia and Hyundai (September and October 2018) requesting information on all engine and non-engine related fires in the petition vehicles.ODI performed extensive analysis on the information obtained from Kia and Hyundai. During the DP18-003 analysis, Kia and Hyundai each initiated three additional safety recalls related to engine compartment fires on certain petitioned and non-petitioned vehicles (nearly 740,000 total vehicles: Recalls 18V-907, 18V-934, 19V-101, 19V-063, 19V-120, and 19V-204). Based on ODI?s review of the applicable materials, including responses to Information Requests sent to multiple manufacturers, Vehicle Owner Questionnaires (VOQ), and Early Warning Data, NHTSA decided to grant the petition.The CAS petition was granted on March 29, 2019. Preliminary Evaluations (PE19-003 on Hyundai and PE19-004 on Kia) have been opened to assess the scope, frequency, and potential safety-related consequences of alleged defects relating to non-collision vehicle fires in the 2011-2014 Kia Optima and Sorento, 2011-2014 Hyundai Sonata and Santa Fe, and 2010-2015 Kia Soul.Attached is a list of the reference numbers for the 404 VOQs cited above.

RQ17003 · Scope And Timeliness

Opened May 18, 2017 · Closed Dec 22, 2021

Status: closed (inferred from source dates) · Engine

NHTSA opened Recall Query (RQ) 17-003 to investigate the timeliness and scope of Kia?s Theta II GDI engine recall (Recall No. 17V-224), and Kia?s compliance with reporting requirements. On November 23, 2020, the Agency entered into a Consent Order with Kia to administratively resolve NHTSA?s assertions of violations of law in connection with RQ17-003. NHTSA?s assertions included that Kia may be liable for civil penalties on multiple grounds, including that Recall No. 17V-224 was untimely and Kia?s recall report contained certain inaccuracies.Under the Consent Order, Kia agreed to a total civil penalty of $70,000,000. The total civil penalty included a payment of $27,000,000 as a Non-Deferred Amount.Kia also agreed to a sum of $27,000,000 as an Abeyance Amount to be deferred and held in abeyance pending its satisfactory completion, as reasonably determined by NHTSA, of the requirements of the Consent Order.Kia also agreed to a $16,000,000 Performance Obligation Amount to be expended by Kia to fulfill specified Safety Data Analytics Infrastructure obligations. The Consent Order also includes other terms designed to enhance Kia?s safety practices, and requires Kia to retain a Third-Party Auditor who directly reports to NHTSA.Other than RQ17-003, the Consent Order is not intended to affect any other current or future investigation of NHTSA which may involve vehicles equipped with Theta II GDI engines. In particular, Engineering Analysis (EA) 21-003 (which is upgraded from Preliminary Evaluation (PE) 19-004) continues NHTSA?s evaluation of certain performance and design issues relating to the Theta II and other engines.Nothing in the Consent Order discharges Kia from any obligation to comply with the Safety Act or regulations thereunder, including the obligation to carry out recalls in accordance with the law, and to initiate a recall upon any future determination by Kia, or upon any finally adjudicated order from NHTSA, that vehicles equipped with Theta II GDI engines contain a defect related to motor vehicle safety or do not comply with an applicable FMVSS.This RQ is closed. Closure of this RQ has no bearing on the terms of the Consent Order, including Kia's ongoing performance obligations, and does not represent a determination by the agency as to Kia's performance under the Consent Order to date.
