  I was driving the vehicle home on the freeway after just buying it. I had only driven it for about 35-40 minutes and after 5 minutes the ev battery was drained completely and the car was running in hybrid mode. The vehicle suddenly lost all its power and a warning light came on flashing saying "check hybrid system turn off engine". I was forced to put on my emergency lights and quickly move over to the side of the freeway because the car lost so much power so quickly. It felt like the engine died and when i tried hitting the gas the vehicle would jerk. ONCE I got to a safe spot on the freeway. I called AAA to get a tow, then called the dealer to tell them. My wife and I have now checked the recalls for this car and all the customer complaints. There seems to be a similarity with the engine recall and or the hybrid electrical recall. It seems like Kia is making sure to cover its tracks with the cars so it doesn't have all the 2017 models in the recalls affecting the hybrid system as well as the defects with the engine components. There is definitely a problem. But i saw in the carfax that the vehicle was inspected a lot by KIA and that is why i would like it to get inspected by a 3rd party. I would like to get the vehicle inspected by a 3rd party before taking it to a KIA dealer but I don't have a lot of money. Can you help with this at all. Please contact me asap. You have the Vin. I told you I just bought the car so I am going to either see if the dealership I bought it from will fix the problem since it broke down the day I bought it. You should be able to see we bought the car from by looking at the carfax for the Vin. And you have my permission to also be able to get my phone numbers from that dealer I really don't think KIA should get away with these hybrid/engine problems with the car. Its very unfair to the consumers. If they as a manufacturer and dealerships are doing quick fixes when doing regularly scheduled maintenance. Thats unethical.

  This car was purchased [XXX] and has been in my possession for 3 years and 4 months. It has sat in a dealership repair facility for 13 of those months to replace the engine and high-voltage hybrid battery. Meaning I have actively driven this vehicle for approximately 27 months and the retraction system for the seatbelts is malfunctioning and as its a safety issue I feel the need to report this and see what other alternatives are available instead of paying out $1121.58 for something that malfunctioned under the first 10 years of the vehicles life sounds more like a design flaw than a user issue or uneasy wear as I am a [XXX] average build individual. As the vehicle went into the dealership for routine scheduled maintenance I noticed the driver and passenger seat belts don’t lock or retract properly. Service tech stated the retraction system is malfunctioning and they will both need to be replaced. With this system not working the driver and passenger are not able to be restrained properly in case of an accident. No lights or warnings appeared just noticed while driving in rush hour traffic in Buffalo, New York. *With this being a “more rare” PLUG IN HYBRID variant instead of a conventional ICE many issues don’t carry over so I would really like this to be investigated for the safety of the owners of this car.* INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  I was getting on the freeway and my car suddenly just stopped accelerating. I even tried pushing the pedal to the floor and all power was gone. I was almost ran down by a 18 wheeler who must not have noticed my hazards had been switched on. A warning came on “check hybrid system. Turn off engine” When the car lost its momentum as I was pulling over and eventually came to a stop I followed the warnings directions and shut the car off since I couldn’t get any further anyways. I tried turning the car back on and then all lights and power instantly started flickering on and off and going crazy and then the warning came back on and then the whole car shut off by itself. I have been too scared to drive it since and I just got it back in October and I need a car to get to work and school and I don’t know what to do but the amount of danger this issue put me in is unsettling and cannot be overlooked. Not sure what caused the malfunction because so many different things happened at once that it was hard to tell It is available for inspection upon request A service center confirmed that there is a problem and they believe it is related to the coolant pump and hybrid battery There was one other time that a warning came up and it just said “check hybrid battery” but it went away only like a minute later and then a couple days after that I came outside to go to work and the car was dead but then I jumped it and it was fine up until the issue I first mentioned happened where I was put in danger A warning light that said !HEV and the check engine light both appeared

  This pre-owned vehicle lost power at an intersection with my wife and child in the vehicle. Both of them were fearful and in tears. Several indicator lights suggested problems with the engine, HEV system , and battery. Upon returning home, I notified Carmax and scheduled the vehicle for service at a local Kia dealership. Although the mechanic told me that he knew there is a problem with the vehicle, Kia failed to diagnose or fix the problem(s), and could not assure me that the vehicle was safe to drive. Maxcare would not cover a rental car because no diagnosis was made. Kia also informed me of a previously undisclosed, long history of problems going back to 35 miles on the odometer. I requested a copy of Kia's vehicle history report and Kia refused to provide it. I also reported this safety concern to Kia Consumer Affairs, who provided no immediate solution, said they would contact the local Kia dealership, and referred me to an "ongoing" class action settlement at [XXX] , which indicated that the settlement had closed on 8/9/21. Because no other option was offered to me, I was forced to pick up the vehicle from Kia. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  I took my car into the local Kia dealership after my engine failed while driving down the highway. I was approved for the engine replacement due to the recall. However after my engine was replaced, and still in the shop, the side curtain airbag module gave an error due to low voltage. Now I'm out $1200 for an item that should not fail within the first 6 years. I have had vehicles 3 times as old that did not have safety sensors or features failing. As Kia obviously has issues with airbag modules I believe my vehicle year and model should be included in this recall. Anytime there are multiple complaints for a failing safety feature on a vehicle less than 10 years old, the manufacturers should have an indepth investigation by an independent agency. These recalls should not be so narrow focused when there are many other models and years that have the same issues. Putting the responsibility on consumers to file complaints and beg for recalls to be issued seems like a backward system that is a burden to those that can't affoard to wait to MAYBE be reimbursed IF their car gets included in a recall later. When searching complaints for Kia airbags, there are several models/years that are not covered under current recalls.

  While driving the car on the highway, when I try accelerating, the car suddenly acts as if it's in neutral and the engine roars without engaging a higher or lower gear and the car start losing power/speed. It takes like three to five seconds to engage a gear again; I have to lift my foot from the pedal a little bit and wait for it to lock on a higher or a lower gear for me to accelerate again.

  Getting onto the freeway accelerating, when heard rattling and saw smoke, exited the freeway and parked the vehicle. There was no warning or lights that came on prior or during this time. Had the car towed to the nearest KIA dealership in city of carson. I received a phone call on saturday 1/2/2021 from tony at the dealership asking for permission to diagnose the vehicle. I agreed to the diagnostic testing. Received a call back within an hour to notify me that there was a hole in the engine, no repairs could be done and I needed a new engine. I asked how did the hole get in the engine. He said there was an internal rod that shot out of the engine creating a hole. It will cost $8,875 and will take around 3-4 weeks to repair. I purchased this vehicle in october 2017 with approx. 3000 miles on it. Started having issues with electrical about a month or two after purchase 2017-2018. I had to have it towed to the KIA in cerritos because it was inoperable, since then we have had it in to be serviced and have had multiple issues. Including another major issue in august 24, 2020 when they repaired the active air flaps and a new battery.

  The plug that IS attached to the charging cable for my electric charger caught fire while plugged into a dedicated wall outlet in my garage. fortunately, no major structural damage nor bodily harm received . I contacted KIA and they have since replaced the charging cable with no further investigation or explanation as to what may have caused this to happen. as you can see from the pictures attached, the plug actually melted a little. I do believe major damage was subverted because I noticed my car was not charging and pulled the plug out of the wall to see if it needed to be re plugged. I don't know what would have happened had I not caught this right away. usually I leave my car to charge over night. scares me to think what could have happened.

  While driving my KIA hybrid a notice came up on the dash board to immediately pull over and shut off my engine and I was on a major highway going about 75 when I lost total power and my vehicle began to loose power. I was able to get it off the road and immediately called my dealer. I had know about this because a relative and I brought the cars the same day and she experience this 3 times.the dealer said it was a switch that got stuck when the car goes from electric to gas. I spoke with KIA and they said there IS no formal recall. but this has now happen to me and a relative I know of. the person I spoke with took it very lightly but I said it IS very difficult getting a car off the road that IS losing power. Have there been any other complaints of this type and IS there a informal recall. I am bringing the car to the dealer tomorrow and they are replacing the switch. My car only has 2000 miles.

  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.

  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.

  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.
