Greetings, I have a base 2016 kia soul manual transmission that I thought was under safety recall for its engine, but when I search it says 0 unrepaired recalls, when I look this up it does claim my vehicle had this problem, but I never had a dealer fix it, I did contact the one I got it from a couple of years ago and asked if my vehicle qualified for the recall since it already has 200,000 miles on it but they never got back to me, did they just claim to fix it, because it has not been worked on. Still runs great at 300,000 miles but if the engine has a safety issue that might catch on fire then I want to get it addressed regardless of its high mileage

A. Safety Defect and Failure Sequence I am filing this complaint because my Kia Soul, which is subject to the widespread engine defect and extended warranty under the Hyundai/Kia Class Action Settlement, suffered a catastrophic failure immediately following dealership intervention. Responsible Action: I brought the vehicle to the authorized Kia dealership on September 25th the instant the Check Engine Light illuminated for the very first time. The vehicle was driven to the dealership under its own power. Triggering Event: The dealership performed the required engine-related software update (Knock Sensor Detection System, KSDS) and routine service. Immediately following this service, the engine went into limp mode and ceased functioning, requiring a complete engine replacement. This sequence strongly suggests the failure was either caused by the known defect covered by the recall or was triggered by the software update itself. Manufacturer Denial: Kia is denying the claim under the Class Action Extended Warranty (which provides a lifetime or 15-year/150,000-mile warranty) using the unsubstantiated and unjustifiable excuse of "damage done prior to bringing the car in." B. Manager Misconduct and Manufacturer Bad Faith The Service Manager, Braden Anaya, has demonstrated calculated deception and bad faith, resulting in severe financial and logistical harm: Fraudulent Promise: The manager explicitly promised me the engine replacement would be approved if I titled, registered, and insured the vehicle. Relying on his direct word, I incurred a financial loss of $800 in fees for an unusable vehicle. Documented Deception: After a long delay, Mr. Anaya sent a formal denial email on December 5th confirming Kia would not cover the engine replacement. Despite this formal denial, he then contacted me and demanded "trust and patience," claiming he was actively fighting the claim for the following three weeks. This was an intentional stall and clear act of deception. Logistical Negli

The contact owns a 2016 Kia Soul. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The contact became aware that there was oil leaking from the engine near the spark plugs while checking prior to the warning light being illuminated. The vehicle was taken to a local dealer who diagnosed the vehicle and determined that the head gasket needed to be replaced. The vehicle was repaired; however, the vehicle was still leaking oil, and the check engine warning light was illuminated. The contact was constantly adding oil to the engine. The contact had taken the vehicle back to the same dealer and was advised that the catalytic converter needed to be replaced, and a tune-up was needed. The catalytic converter was not replaced, and the contact stated that the engine was still leaking oil. The vehicle was not repaired. The contact had taken the vehicle to several independent mechanics and was advised that the engine needed to replace, however the vehicle was not repaired.

While driving my 2016 Kia Soul on the highway, the vehicle suddenly began shaking and immediately lost power. The check engine light came on and the car would not accelerate, even when pressing the gas pedal. This happened with no prior warning. I had to coast to the shoulder in moving traffic, which created a safety concern. The engine then stalled completely and would not restart. The vehicle was towed to Findlay Kia in Las Vegas. Their technicians diagnosed a major internal engine failure. The repair report shows zero compression in cylinder 2, a cracked intake valve, oil contamination, and extensive internal engine damage requiring a full engine replacement. Diagnostic trouble codes included P0300, P0302, P0303, and P0326. There were no earlier symptoms, no overheating, and the vehicle has been properly maintained. The failure was sudden and left the car completely inoperable. I opened Case #[XXX] with Kia Corporate. They reviewed all documents, service records, and the dealer’s findings. Although they did provide assistance in reviewing the case, the final outcome was not in my favor, and they declined to cover the repair. This is concerning given the history of engine-related issues and recalls involving Kia Souls from similar model years, particularly involving sudden engine failure and loss of power. My vehicle remains inoperable at the Kia dealership. The sudden loss of power while driving presents a clear safety risk. Based on my experience and the dealership’s findings, I believe this engine failure is safety-related and should be evaluated further by NHTSA.

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.
