AS I STARTED TO ACCELERATE THIS TIME THE SOUND GREW TO A HARD POUNDING NOISE. BEFORE I COULD EVEN PULL OFF THE ROAD MY CAR COMPLETELY SHUT DOWN. I LOST ALL POWER AND MY WHEEL LOCKED UP. I TRIED TO START IT AGAIN, NOTHING. I HAD TO TOWED TO MY LOCAL MECHANIC AND AFTER A FEW HOURS IT WAS DECLARED AS "CATASTROPHIC ENGINE FAILURE". KEEP IN MIND THE CAR HAS ONLY 61,000 MILES ON IT! AT THIS POINT I HADN'T TOWED TO KIA FOR INSPECTION AND THEY DETERMINED "COMPLETE ENGINE FAILURE". "SOMETHING HAS COME LOOSE INTERNALLY". THIS ENGINE IS A OBVIOUS DEFECT.

I WAS ENTERING THE FREEWAY, ACCELERATED TO MATCH TRAFFIC SPEED, I HEARD THE ENGINE'S RPMS INCREASE BUT ALMOST IMMEDIATELY AFTERWARDS THE CAR SHUT DOWN. I WAS IN THE MIDDLE LANE OF A VERY BUSY INTERCHANGE AND GOING ABOUT 60MPH WHEN THE CAR QUIT. I KEPT TRYING TO RESTART THE CAR BY PUTTING IT IN NEUTRAL AND AT THE SAME TIME STEER IT TOWARDS THE SHOULDER. THERE WERE NO WARNING LIGHTS. WHEN I HEARD THE ENGINE NOISE I LOOKED AT THE DASH, ALL WAS NORMAL, THE D FOR DRIVE WAS VISIBLE. IT HAPPENED VERY QUICKLY. ONCE STOPPED AND OUT OF TRAFFIC, I TRIED TO RESTART THE CAR, IT RAN FOR JUST SECONDS THEN NOTHING. THIS CAR HAD JUST BEEN SERVICED AT THE KIA DEALER. IT ONLY HAS 51K MILES ON IT. I HAD TO HAVE IT TOWED TO THE DEALER. THEY ARE TELLING ME THE ENGINE IS FAULTY BUT THEY DON'T MAKE IT ANYMORE AND THEY HAVE NO RESOLUTION FOR ME. THE CAR IS ONLY 4 MONTHS PAST THE 5 YEAR MARK AND IT IS UNDER 60000 MILES. IT HAS BEEN MAINTAINED PERFECTLY, IT STILL LOOKS NEW. THE ORIGINAL OWNER DID ALL THE SERVICE AS WELL. KIA KNOWS THEY HAVE FAULTY ENGINES, YET THEY DO NOTHING TO WARN THE OWNERS OR REMEDY THE PROBLEM. THE SAY THEIR CARS ARE GOOD FOR 10YRS OR 100K MILES, THEN THEY SHOULD MAKE IT SO.

I AM THE ORIGINAL OWNER OF MY 2013 KIA FORTE EX, THE VEHICLE ROUGHLY HAS 70,000 MILES ON IT. THE VEHICLE HAS ALWAYS BEEN PROPERLY MAINTAINED VIA OIL CHANGES, FILTERS, ETC ON TIME WITH QUALITY NAME BRAND FULLY SYNTHETIC OIL AND FILTERS PER THE MANUFACTURER'S RECOMMENDED MAINTENANCE SCHEDULE WHICH IS EVERY 7500 MILES. I WAS DRIVING MY VEHICLE HOME ON A VERY BUSY FREEWAY ON THE EAST COAST. I WAS IN THE CENTER LANE OF 5 LANES ON THE SOUTH BOUND SIDE AND ALL OF A SUDDEN MY CAR LOST ALL POWER AND WAS SLOWING DOWN AT AN UNSAFE RATE OF SPEED BECAUSE I HAD NO POWER AND DID NOT WANT TO TOUCH THE BRAKES OBVIOUSLY. I PANICKED BUT WAS ABLE TO PUT MY RIGHT SIGNAL ON TO TRY AND GET TO THE SHOULDER OF THE FREEWAY I CONTINUED TO PANIC BECAUSE MY CAR WAS STEADY SLOWING AND EVENTUALLY WOULD COME TO A STOP BECAUSE I HAD NO POWER, THE GAS PEDAL WOULD NOT FUNCTION AND I KNEW THE CAR SHUT DOWN BECAUSE ALL THE LIGHTS WERE ON ON THE DASH AS IF YOU WERE STARTING THE CAR. THANKFULLY SOMEONE WAS WATCHING OVER ME THAT DAY AND I MADE IT TO THE SHOULDER BEFORE THE CAR ROLLED TO A COMPLETE STOP. IF I WERE UNABLE TO SAFELY MOVE OVER TWO LANES AND MAKE IT TO THE SHOULDER ON MOMENTUM I WOULD HAVE BEEN STOPPED IN A LANE OF TRAVEL ON A BUSY FREEWAY AND WHAT WOULD I HAVE DONE? I PROBABLY WOULD HAVE CAUSED AND BEEN PART OF A MAJOR ACCIDENT, EVEN THOUGH I DID MAKE IT TO THE SHOULDER I WAS STILL PANICKING BECAUSE THIS IS A VERY BUSY FREEWAY AND I FELT HELPLESS. THE CAR WOULD NOT START IT WOULD MAKE A FUNKY NOISE AND THAT'S IT BUT WOULD NEVER START SO I WAS STRANDED. I LOOKED IN MY OWNERS MANUAL AND CALLED KIA, THE DEALERSHIP WAS 10 MINUTES FROM MY LOCATION. I WAS TOLD THERE WAS NOTHING THEY COULD DO BECAUSE THEY DIDN'T HAVE A TOW TRUCK AND I WAS ON MY OWN. I HAD THE CAR TOWED THERE AND WAS TOLD THE ENGINE BLEW UP AND IT WAS THE BOTTOM END. I BELIEVE IT WAS IN THE TIMING SYSTEM AND KIA IS LYING.

18V363000 · Air Bags: Air Bag/restraint Control Module

Jun 1, 2018

Kia Motors America (Kia) is recalling certain 2010-2013 Kia Forte, Forte Koup, 2011-2013 Kia Optima and 2011-2012 Kia Optima Hybrid and Sedona vehicles. In the event of a crash, the air bag control unit (ACU) may short circuit, preventing the frontal air bags and seat belt pretensioners from deploying.

Consequence & remedy

Consequence: If the frontal air bags and seat belt pretensioners are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.

Remedy: Kia will notify owners. For model year 2011 Sedona vehicles, Kia will instruct dealers to verify the ACU part number and, if necessary, install an extension wire harness kit between the ACU Connector and the Vehicle Harness Connector. For all other affected vehicles, Kia will instruct dealers to install the extension wire harness kit. The recall began September 28, 2018. Owners may contact Kia customer service at 1-800-333-4542.

17V773000 · Service Brakes, Hydraulic:pedals And Linkages

Dec 1, 2017

Kia Motors America (Kia) is recalling certain 2012-2014 Forte and Forte Koup vehicles. The brake pedal stopper pad can deteriorate allowing the brake light switch plunger to remain extended when the brake pedal is released. This will allow the brake lights to remain illuminated continuously. It can also allow the shift lever to be moved without depressing the brake pedal, or activate the engine management brake pedal override feature.

Consequence & remedy

Consequence: If the brake light switch plunger does not retract as it should when the brake pedal is not being pressed, the brake lights may stay illuminated preventing accurate communication to following vehicles that the vehicle is slowing or stopping. Additionally, if the brake switch plunger is not retracted, then the transmission can be shifted out of PARK without depressing the brake pedal. Either condition increases the risk of a crash.

Remedy: Kia will notify owners, and dealers will replace the brake pedal stopper pad, free of charge. The recall is expected to begin January 30, 2018. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC158.

AQ23002 · Hyundai And Kia Abs Module Fires

Opened Nov 17, 2023 · No close date supplied

Status: open (inferred from source dates) · Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip:control Unit/module

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.

EA21003 · Engine Fires

Opened Dec 22, 2021 · Closed Feb 5, 2024

Status: closed (inferred from source dates) · Engine

On March 29, 2019, the Office of Defects Investigation (ODI) opened two Preliminary Evaluations (PE19-003 on Hyundai and PE19-004 on Kia) to broadly investigate incidents of non-crash fires (regardless of origin or operational status of the vehicle) on various model year Hyundai and Kia vehicles.  During the PE investigations, Hyundai and Kia issued several recalls to address vehicle fires, including those due to engine failures involving various engine types.  The remedies for the engine failure recalls typically involve engine inspection (to detect existing damage), and if necessary, engine replacement.  Additionally, both manufacturers have been installing an engine control software modification known as Knock Sensor Detection Software (KSDS) which is intended to detect impending engine failure, alert the driver, and limit engine power (to lessen likelihood of engine failure).KSDS is being installed under recalls and non-safety field actions, and both companies have extended limited engine warranties (see recall files). On December 22, 2021, ODI upgraded PE19-003 and PE19-004 to this Engineering Analysis (EA21-003, covering both Hyundai and Kia) to evaluate the scope of the prior recalls related to engine failures/fires and the efficacy of the recall remedies for the recalls, as well as the long-term viability of related programs and non-safety field actions being conducted by Hyundai and Kia.  The former issue involved approximately 550,000 MY 2013 Hyundai Elantra, MY 2011 Kia Sorento, and MY 2012-2015 Kia Rio.  The latter issue involved approximately 2.5 million recalled vehicles, which have been identified as displaying potential remedy concerns: Hyundai recalls 15V-568, 17V-226, 20V-746, and 21V-727; and Kia recalls 17V-224, 19V-120, 20V-750, and 21V-844. Regarding the recall scope issue, among all of the scope vehicles identified at EA opening, ODI found only the MY 2011 Kia Sorento vehicles equipped with both the Theta II 2.4L 4-cylinder Multi-Point Injection (MPI) and the Lambda II 3.5L 6-cylinder MPI engines experienced relatively high rates of reported fires.  In December 2023, Kia issued recall 23V-877 that will cover about 80,000 MY 2011 Kia Sorento vehicles equipped with the Theta II 2.4L MPI engines.  The remedy will involve an inspection, and if necessary, a replacement of the engine, as well as the installation of KSDS.  It should be noted that in 2021 these vehicles were included in a KSDS product improvement campaign with warranty extension.  For the MY 2011 Sorento vehicles equipped with the Lambda II 3.5L engines, ODI believes that future engine failures/fires involving these vehicles will likely be due to a lax in adhering to the proper or scheduled engine maintenance (regular engine oil changes), rather than a design or manufacturing engine issue. Regarding the issue of the efficacy of the recall remedies, ODI found the majority of the recalled Hyundai and Kia vehicles, by model, experienced lower reported fire rates after the remedies were applied.  Furthermore, ODI found that for most vehicles that did not receive the recall remedies, by model, experienced relatively high fire rates.  To address this problem, Hyundai informed ODI in December 2023, that it will renotify all of its owners covered by the Hyundai recalls of engine failures/fires every 8 months for the next 3 years.  In December 2023, Kia stated that it will renotify the majority of its owners every 8 months for the next 3 years.Several previously recalled Kia models are excluded from the renotification due to their lower reported rates of engine fires.  Overall, the renotification actions will help to increase the recall completion rates, thus reduce the frequency of engine fires in the future. In view of the recall action being taken by Kia and renotification actions being taken by both Kia and Hyundai, ODI is closing this Engineering Analysis.  Also, both companies have been released from the 2020-iniated Consent Orders (Kia since November 2022 and Hyundai since November 2023).  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.

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.

The Office of Defects Investigation (ODI) opened PE18-003 on 3/16/18 to investigate incidents involving crashes, resulting in significant collision related damage, where the frontal airbags failed to deploy. ODI reviewed complaint data, available design, test, and field data on the model year (MY) 2011 Hyundai Sonata, MY 2012-2013 Kia Forte and Forte Koup vehicles. ODI also evaluated data from the automotive air bag system supplier, ZF-TRW (ZF), to review vehicles that may contain the same air bag control unit (ACU) used in the subject vehicles. Hyundai Motor America (HMA) issued recall No. 18V-137 for MY 2011-2013 Sonata and MY 2012 Sonata Hybrid vehicles. Kia Motors America (KMA) issued recall No. 18V-363 for MY 2010-2013 Kia Forte and Forte Koup, MY 2011-2013 Optima, MY 2011-2012 Optima Hybrid, and MY2011-2012 Sedona vehicles. The two recalls address vehicles containing ACUs manufactured without adequate circuit protection by installing a wire harness filter kit to prevent internal damage to the ACU. In the event of a crash, ACU damage may result in the disablement of the vehicle's airbags. Each respective manufacturer has mailed letters to affected vehicle owners informing them of the remedy and its availability.
