Sudden engine misfire and stall in major metropolitan area in high traffic. Diagnosis from my mechanic was failed valve and complete loss of compression to 2nd cylinder. Symptomatic of repeat catalytic converter issues leading to engine damage. Catalytic converter has been replaced twice-- once out of pocked and once under extended warranting for SC176/the federal safety agency 19V-120000 at a kia dealership. Engine light turned on just minutes before failure. I am now beyond the extended 150,000 warranty-- engine failed at 167,000.

Engine
- What is wrong
- Kia Motors America (Kia) is recalling certain 2012-2016 Kia Soul vehicles equipped with 1.6L Gasoline Direct Injection (GDI) engines. High exhaust gas temperatures may damage the catalytic converter, possibly resulting in abnormal engine combustion and damage to one or more of the engine's pistons and possible piston connecting rod failure.
- Risk
- Piston damage may result in an engine stall, increasing the risk of a crash. A broken connecting rod may puncture the engine block allowing engine oil to escape. The leaking oil may contact the exhaust, increasing the risk of a fire.
- Remedy
- Kia will notify owners, and dealers will upgrade the Catalytic Overheating Protection Engine Control Unit logic to prevent overheating of the catalytic converter. In addition, the catalytic converter will also be replaced if it has been damaged. Depending on the extent of any damage, the engine may also be replaced, free of charge. The recall began April 17, 2019. Owners may contact Kia customer service at 1‑800‑333‑4542. Kia's number for this recall is SC176.

Engine Fires
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

Most recent owner complaints, unedited.
Recall sc176 incomplete- while driving in an unincorperated area in [xxx] ([xxx] in [xxx] county) the vehicle suddenly lost engine power and due to the sudden loss of engine power the vehicle was difficult to stop on a dangerous curve. The vehicle would not start back up. The cruve was situated in such a manor that it was unsafe to try to push it into the side as it was a steep ditch leaving the vhicle completely disabled in the complete dark. Even with the flashers on other motorists including a semi tractor trailer nearly crashed into the disabled vehicle multiple times. While escaping the dangerous situation on foot I noticed the muffler was emmiting smoke and a strong odor. I was able to retain the services of a local towing company to provide immediate emergency response where they had to use multiple units with cones and amber lights and flagmen with strobes to set up a saftey zone to protect oncomming motorists while they cleared the immediate saftey hazard. That week I had a local mechanic shop check on the no start condition. They removed, charged, and bench tested the battery finding it to perform at an acceptable amperage. Upon inspecting the no start condition found the motor to be lockrd. They noted an incomplete saftey recall upon checking the VIN and advised the vehicle needs to go to an authorized dealer for recall service. At that point the vehicle was pushed into an outdoor storage lot and the key returned pending transport. I talked to a lady at the kia dealer in [xxx] where it was mentioned they only had 2 technicians and it would be a while to get it looked at, so I called the next closest dealer which is [xxx]. On the phone they told me to bring the car for recall inspection. Instead of processing the recall they text me mentioning diag fees and costs and tried to get me to trade it in instead. I feel duped having it towed there for recall based on there words just for them to try to get me to trade it in.

My husband purchased our 2015 Kia Soul 1.6L GDI in 04/18. It was recalled under the federal safety agency 19V120 & Kia SC176 in 04/19. The recommended fix? Update ECU Logic. Completed: 04/24/19. Check engine light came in 07/19. My appointment in 08/19, at #1 Cochran Kia showed a P0455 large leak code. Per invoice, manual leak test found no leak, but found gas cap not installed correctly after adding fuel, codes were cleared, & road test performed; "mileage in": 65582, "mileage out": 65583. Was that a road test? In 01/20, the Soul at the dealer for check engine light; P050A code was found & there was no resolution. They sent me home with the check engine light on. Auto Zone recommended catalytic cleaners. I used these because the illuminated check engine light created stress & still does. Auto Zone found another P0420 code for replace catalytic converter on 08/21. More cleaners. 01/22 Auto Zone found replace ignition coils & spark plugs. 04/22 extended warranty expire At dealer on 01/23, for a check engine light. A catalytic converter replace was recommended for $2,199.95. I could not afford that. More cat cleaner. Auto Zone found P0420 code on 06/23. Cat cleaner did not work. I found a cat for $379.80 & asked an auto tech to install. Codes cleared only for a little while. I kept using catalytic cleaner. Soul's mileage was greater than max of 150,000 during '23 settlement. On 09/28/26, the car slowed down when accelerating up hill & check engine light began blinking. Stressed, 3 friends & I were picked up by another friend. At home, P0300 led to spark plugs & ignition coils being replaced & a possible exhaust leak. An appointment is scheduled on 10/14/26 but the dealer plans to charge a diag. fee for $190. Kia released SC176Y an extension to SC176, directing dealerships to replace catalytic converters & parts of the engine if a car is exhibiting the P0420 & P0300 codes after the 2019 ECU logic update. Can my VIN have these replaced? The original cat converter is available.
