My engine light came on about 6 months ago because I was smelling a gas. I had it run on a code computer and it just showed a gasket needed changed. I didn't think that that was serious enough to address urgently because was unsure how much the cost would be. But was going over a big mountain about a week ago and car was on cruise control at 55 Mpr and all of a sudden it just started dropping down totally stopping on me in very active traffic had my grandchild in the car also, got off the road barely in ongoing traffic and called for roadside assistance, but my son showed up and got it to start I barely got it back to his house in Rogersville tn. Where I was staying for a visit , I Ran a code computer on it again and it said it was the Cadillac converter, I looked it up and there is a recall on this situation. Why your sight is saying it's 0 idk why. This is my report and I think u need to change that problem there . I am currently still at my sons house staying cause I can't get my car home cause it won't climb clinch mountain or any sharp hills. Thank you

The vehicle burns an unreasonable amount of oil. This clogs tue catalytic converter creating risks of breakdown or fire. There are many documented cases of this on the vehicle models and yet Kia has not resolved. Instead we pay for the issue. Car ownership has been consistent on maintenance and yet this issue remains.

The contact owns a 2015 Kia Soul. The contact stated that while driving 40 MPH, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended, with the check engine warning light illuminated. The vehicle was towed to the dealer where it was diagnosed with knock sensor failure, valve cover gasket failure, and an inoperable oil pan. The contact was informed that the knock sensor, valve cover gasket and oil pan needed to be replaced. The vehicle was repaired. The vehicle was released to the contact. The contact stated that within two minutes after leaving the dealer, the failure reoccurred. The check engine warning light illuminated and the engine sputtered. The vehicle was taken back to the dealer where it was diagnosed with a clogged catalytic convertor. The contact was informed that the catalytic convertor needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 118,981.

The vehicle is a 2015 Kia Soul with the 1.6L GDI engine. The check engine light came on solid, and a dealer later confirmed diagnostic trouble code P0420, indicating the catalyst system efficiency is below threshold on bank 1. The catalytic converter and engine are still on the vehicle and available for inspection upon request. This condition matches the defect described in Kia’s SC176 safety recall for 2012–2016 Soul vehicles with the 1.6L GDI engine, in which overheating of the catalytic converter can lead to internal engine damage and even a fire. My concern is that a failing catalytic converter or related engine damage could lead to sudden loss of power, engine failure, or fire while driving, which puts my safety and the safety of others at risk. The problem has been confirmed by an authorized Kia dealer, which documented the solid check engine light and DTC P0420 on a written repair estimate. In that document, the dealer referenced recall SC176Y as the possible applicable recall and noted that it would need to contact Kia for coverage because the vehicle has a branded rebuilt title. To my knowledge, the manufacturer has not yet performed any SC176‑style ECU logic update, compression test, or catalytic converter/engine inspection on this vehicle, and the manufacturer has declined to escalate or review recall coverage for this defect. The check engine light and P0420 code remain the primary warning indicators, and they first appeared shortly before the dealer visit on the repair estimate date.

The contact owns a 2015 Kia Soul. The contact received notification of NHTSA Campaign Number: 20V750000 (Engine). The contact stated that while her husband was driving at 20 MPH, the Check Engine warning light illuminated, and the vehicle stalled. The vehicle could not be restarted. The vehicle was pushed to the residence, then towed to a dealer, who stated that the failure was related to the active recall, although the diagnosis was unclear. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 134,700.

The vehicle exhibited a severe mechanical engine knock, significant magnetic iron debris in the engine oil, and subsequently triggered diagnostic trouble code P1326 (Bearing Wear Limit Exceeded). This indicates imminent connecting rod bearing failure, which is a known defect subject to lifetime warranty extensions and safety recalls under the Hyundai/Kia Engine Litigation. This defect poses a severe safety risk, as it can cause sudden engine seizure, catastrophic loss of motive power at highway speeds, or an engine fire, creating an immediate crash hazard. The vehicle was presented to an authorized Kia dealership service center for diagnosis. The dealership completed a static "Bearing Clearance Test" (BCT) which resulted in a procedural pass. However, the authorized service advisor explicitly stated on a recorded voicemail that the engine "is having issues" and that the dealership "can't put on the ticket that everything is completely safe". Voicemail recording can be provided. Despite acknowledging on the record that the vehicle is unsafe to operate, the dealership and manufacturer refused to authorize the necessary engine replacement repair, citing the static test result. Furthermore, dealership staff instructed the consumer (myself) to continue operating the admittedly unsafe vehicle in traffic until a catastrophic failure occurs on the road to force a diagnostic test failure. The manufacturer's reliance on a test protocol that fails to identify physically disintegrating components, combined with instructing consumers to drive vehicles admitted to be unsafe, constitutes an extreme and ongoing safety hazard.

On the highway, not reaching speed at expected RPM, try increasing power and RPM stops climbing at 3500, and speed decreases suddenly, car starts bucking, check engine light flashing. I pull over, stop, and keep going after several minutes idling with no apparent issue continuing. I take the car to get a computer check of the engine light code, P0420 for catalytic converter efficiency. Take car to dealer, they diagnose the converter as being both melted and clogged, quote me $4200 to replace with OEM part. Go to get second opinion at another service center, they confirm converter diagnosis and additionally diagnose cause as relating to outdated ECU software causing converter overheating, something which was an active recall for Kia Soul vehicles from MY 2012-2016, but only the 1.6L models. My vehicle is a 2.0L model with the exact same issue causing the exact same result, but with no recall, the converter is shot and there is no accountability for replacing the damaged part and updating the faulty software, as well as for missing this faulty software in the first diagnostic.
