2014 Kia Soul

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.

During this Preliminary Evaluation (PE), the Office of Defects Investigation (ODI) assessed the scope, frequency and potential safety-related consequences of non-crash vehicle fires caused by both engine failures and failures of other vehicle systems/components in model year (MY) 2011-2014 Kia Optima, MY 2011-2014 Kia Sorento and MY 2010-2015 Kia Soul vehicles equipped with Theta II, Gamma, Nu and Lambda II engines (approximately 1.7 million vehicles). ODI also reviewed field and other data on other Kia vehicles (approximately 3.6 million additional vehicles) equipped with the same engines used in the above-mentioned vehicles.As a result of this PE, Kia has issued NHTSA Recalls 20V-750 and 21V-844 to address potential engine failures and fires in certain Kia vehicles equipped with various engine types.Additional information on these and other related recall actions is available in the downloadable version of this resume available at NHTSA.gov.In addition, ODI has upgraded this PE to an Engineering Analysis (EA) 21-003 which will focus on potential recall scope concerns and recall remedy concerns related to the engine failure-related recalls mentioned above and conducted previously.See the EA21-003 Opening Resume available at NHTSA.gov for more information.Also available in the downloadable version of this resume is a list of the reference numbers for the 444 ODI reports, or Vehicle Owner Questionnaires (VOQs), cited above which ODI received through mid-November 2021.Note that the Manufacturer reports cited above are customer complaints received through March 2019.

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.

The Engine powered down to the point where the car stalled out. It would not accelerate. This was quite dangerous! I was in traffic when this happened. Trying to get it to a safer spot, I restarted the engine a few times; the brakes were extremely hard & wouldn't let me mash them down to catch to stop, so I immediately pulled the handbrake up & shut the engine off. I smelled a weird smell, like something was burning too. I had it towed to the shop & even though No lights were on, we plugged it up & it gave the 0420P code for the Bank 1 sensor Exhaust Flow issue. Mechanic stated he thought it might be the Catalytic Convertor. About 2 weeks beforehand, the oil light had come on, added 2 quarts of oil & it went out. Then the check engine light came on about 2 weeks after that, blinked a couple of times, but went back off.

Writing to get some relief and a recall for my expenses due to a failed catalytic converter. The same issue was reported and recalled on the 1.6l engine in 2019. 19V120.Mine is 2014 kia soul 2.0l engine. I am showing multiple other reports on this site which had the same issues as well. 11736089 and 1700997. Catalytic converter failure. No codes. Sluggish acceleration, rotten egg smell, high fuel consumption and oil consumption. When merging onto highway, engine redesign to between 3-4000 reps before it goes into overdrive have to jam the accelerator to go. Took to mechanic and while they were doing a test drive, could not get the car to go. Narrowly not getting into an accident with the approaching truck behind them. Vehicle has regular maintenance and is well taken care of. Good thing i got it taken care of before engine failure. All of the combustion gases from the failed catalytic converter could have cost me a new engine, or worse my life. Reached out to kia corporate customer service with no help offered. They tout extended warranties on their cars. But will not honor them. Have the converter and it is clear as day , that it was reaching high temperatures and malfunctioning. What help can you offer?

PITSTOP: TECHNICAL OPERATIONS: EXTERNAL DAMAGE TO ULTRASONIC SENSOR: This Pitstop provides information related to Parking Distance Warning (PDW) alerts and repairs involving ultrasonic sensors. The PDW system alerts the driver while parking, by calculating distance based on the difference in signal transmission and reception times between the vehicle (ultrasonic sensor) and an object. The membrane film of the ultrasonic sensor is used for object detention and can be damaged by stone chips or foreign substances while driving. Damage to the cover of the ultrasonic sensor can also lead to damage to the internal circuit. As a result of this external damage, the PDW system may not receive the proper signal from the ultrasonic sensor. In some cases, the system may cause a false alarm, no alert, or phantom warnings by a “Warning Lamp’ to be displayed on the cluster. The ultrasonic sensor membrane film should be always inspected for external damage and if any part replacement should be treated as a general repair, not as a warranty claim repair for this concern. (Please note that this Pitstop only applies to models/trims that are equipped with the ultrasonic sensors.)
