My car started making a ticking noise around 92k. I was afraid to drive it because of all the information id read on the KIA engines catching on fire. I had it towed to a local mechanic who wouldn't touch it and said I needed to bring it to the dealership because I'm still under warranty. I had my vehicle towed again which cost me over 400$ to a KIA dealership. They told me that the engine would need to be replaced but wouldnt tell me why. In fact they REFUSED to tell me why. After I demanded a diagnosis, they stopped responding to my calls.SIX WEEKS they held my vehicle hostage. I called Kia manufacturer customer service who made a call to them. The dealership tried every possible way they could to get out of fixing my engine. I went to the dealership to get something out of my vehicle but they denied me access. After I caught them doing something completely wrong (leaving my vehicle unlocked, keys in the ignition, and trashed on the inside) they decided they would fix my engine. I waited another 4 weeks for my engine to be replaced with a refurbished engine. They did not tell me it wasn't a BRAND NEW engine before they installed. Never even called me to tell me they were starting the work. The day they finished, I got a call demanding for me to pick it up or they would have it towed. Also, all 4 of my tires were "unrepairable and HAD to be replaced or I was in danger for my life if I drove it." I called kia customer service again. The dealership lied to me. They told kia customer service that they just needed to be aired up and the valve stems replaced..... on all 4 tires... very sketchy. After a very straightforward conversation with the manager, I had my car towed him. I'm terrified to drive it anywhere. I don't trust them with anything. They had my car a total of 3 months. I lost a ton of money on rentals and pain, disruption, and anguish in my personal and work life because of it.

NHTSA - I own a 2016 Kia Soul that has a damaged failing engine; the problem is excessive oil consumption. This defect is causing motor oil to migrate into areas of the engine that it shouldn't be, thus inevitably causing a catastrophic failure; rendering the engine inoperable and irreparable. The oil pressure warning light came on only after the damage was done. Horne Kia in Gilbert Arizona, where I purchased the vehicle, has inspected it and found this to be true. However Horne Kia and Kia corporate will not repair or authorize repair, respectively. I was told to continue driving it until the engine is completely destroyed in order to have it repaired...WHAT. So I'm being told that the engine will definitely seize-up and fail leaving me stranded; this is a safety nightmare. What if I'm driving on a highway when this happens. What if the engine failure causes me to lose control of my vehicle and cause who knows what. This not only puts me at risk, it puts others driving around me at risk as well; not to mention passengers that may be in my vehicle.

My 2016 Kia Soul began having acceleration problems mid-December 2022, around 100k miles. I took my car to Kia Service and was told the ECU needed to be updated and that was most likely the cause of the problem. I received the update on 12/14/2022. My car drove a little better for two days but began experiencing the same acceleration issues. I couldn't go over 60 mph on the interstate. It also seemed to be burning gas fast. Although a diagnostic test was attempted twice, there were no findings since the engine light still hadn't come on. It wasn't until 2 months later, 2/11/2023, that my car stalled out on the interstate at 10:00pm at night. I had it towed to Kia and they confirmed the same thing that my reader did on 2/12/23: engine code P1326, knock sensor. On 2/16/23, Kia ran a diagnostic test and came up with the same code, however, they said it is my catalytic converter that needs to be replaced, for approximately $3100. I've read hundreds of reports at this point about the same issues, and they all say the catalytic converter ends up not being the fix or has to be replaced multiple times. It seems like Kia is just determined to not recall these vehicles even though they seem to be a huge safety & liability concern at this point.
KIA Soul had a malfunction with the Catalytic converter and a bad injector which damaged the pinions and the sparks plug of the vehicle causing thousands of dollars in repair.

The contact's son owns a 2016 Kia Soul. The contact stated while her son was driving 10 MPH, the vehicle lost power and would not exceed 2 MPH. The contact's son continued driving and pulled into a repair shop, where it was diagnosed that both catalytic converters had failed and needed to replaced. The vehicle was then towed to the dealer. The contact became aware that the VIN was included in NHTSA Campaign Number: 19V120000 (Engine, Engine And Engine Cooling), which she related to the failure. The dealer informed the contact that the recall remedy only included the Catalytic Overheating Protection Engine Control Unit logic software update. The manufacturer was notified of the failure and advised as the dealer. However, the recall remedy notes stated that the catalytic converter and the engine would also be replaced if they were damaged. The manufacturer informed the contact that the vehicle would be repaired under warranty. The vehicle was not repaired. The failure mileage was approximately 72,631.

NHTSA investigations
1EA21003 · 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.
