2016 Kia Soul: sudden loss of power

Filed Nov 4, 2026 · Brakes, Engine · OH

As the original owner of this 2016 Kia Soul (approx. 124,000 miles), I am filing this safety and consumer compliance complaint for severe engine failure and a failure of manufacturer recall notification systems. On [XXX], my vehicle experienced severe power loss on the highway and extreme oil consumption. An inspection by an independent repair facility revealed catastrophic engine failure due to piston ring degradation, severe crankcase blow-by, and oil contamination of the exhaust system. The repair shop informed me that these symptoms directly align with known manufacturing defects covered under active safety recalls, specifically the federal safety agency Recall 19V‑120 and the Hyundai/Kia Engine Litigation II settlement (No. 8-18-cv-0223-JLS-JDE, C.D. Cal), for which my VIN is a confirmed match. On [XXX], I brought the vehicle to VanDevere Kia of Akron for evaluation. Service associate Jackie Mundri informed me I was denied engine replacement coverage, with Kia claiming I waited "too long" to address the recalls. When I escalated this to Kia Consumer Affairs and spoke with a representative named Cassandra, I was told it was my personal responsibility to proactively check for recalls. I have never received any notification via mail, email, or telephone regarding Recall SC176 or any other engine campaign. Furthermore, within the past two years, I paid out of pocket for major repairs directly related to these exact safety defects (replacing the catalytic converter and two brake lines), yet neither the independent shops nor the dealership flagged these open safety recalls during those services. By blaming the consumer for a lack of communication while failing to provide mandatory notice, the manufacturer is leveraging their own notification breakdown to evade responsibility for a dangerous, defective engine. I request that the federal safety agency investigate Kia's failure to provide proper notification and their refusal to honor safety obligations for a verified class-settlement vehicle.

My vehicle was towed to the dealer to address a recall. Campaign 19V120/SC176. I advised them I had codes #300, 303 &304. I requested a compression test & documentation of the findings. They instead cleared the codes, addressed the ksds software update & declared the car "fixed". Upon leaving, the engine lost power (in traffic) & the check engine light returned. I limped the car back & again requested a compression test which they did not perform even after pulling codes of a "misfire". They pulled the plugs & advised replacement as well as replacement of the coils for $1,200. I believe I'm entitled to knowing the health of the engine by means of a compression test & possible short block replacement if it's deemed necessary (per recall SC176)

Vehicle suffered a sudden, dangerous loss of power on the highway at 70 mph, dropping immediately to 20 mph, creating a severe safety risk. The vehicle has an active P0420 code. The official the federal safety agency database confirms that Safety Recall SC176 (Campaign 19V120) is INCOMPLETE for this vehicle. However, the KIA dealership and KIA corporate are actively refusing to honor the federal recall, falsely claiming the vehicle is past an 8-year/80,000-mile emissions warranty limitation. They are also forcing a $249 diagnostic fee to investigate an open, incomplete safety campaign.

Dear Kia Customer Care, I am writing to formally express my disappointment and serious concern regarding my 2016 Kia Soul, VIN [XXX], its engine failure, the applicable engine recall/warranty coverage, and my experience obtaining assistance and repairs through Kia. Most importantly, this situation involved more than an inconvenience or ordinary mechanical problem. My son's safety was placed at serious risk when my Kia abruptly lost power and became disabled in high-speed freeway traffic. XXX – Dangerous Freeway Breakdown On Saturday, XXXX, at approximately 9:30 p.m., my son, [XXX], was driving my Kia Soul on the [XXX] from [XXX] toward [XXX], for his 11:00 p.m. work shift. According to [XXX], the vehicle abruptly began losing speed and eventually came to a complete stop near the freeway median. The vehicle was left in an extremely dangerous position with high-speed traffic approaching nearby. [XXX] noticed that the check-engine light had illuminated. He repeatedly attempted to restart the vehicle, but it would not start. When [XXX] called me for assistance, I panicked because of the dangerous circumstances. My immediate concern was that my son or another motorist could be seriously injured. I contacted AAA for emergency roadside assistance. Because of the hazardous location, AAA contacted the California Highway Patrol (CHP) to assist until the tow truck arrived. [XXX] was instructed not to leave the vehicle because of the high-speed traffic surrounding him. AAA ultimately towed my Kia Soul to Kia Cerritos because it was the closest Kia dealership I could locate that offered an overnight vehicle drop-off. XXXX – Vehicle Received by Kia Cerritos On Sunday, XXX, a service representative contacted me to confirm that Kia Cerritos had received my vehicle. I was asked what had occurred the previous evening, and I explained the incident in detail. XXX INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2016 Kia Soul. The contact stated that the vehicle failed to start immediately and lost motive power while driving. The contact was able to continue driving at reduced power. Additionally, there were abnormal sounds coming from under the hood, excessive engine oil consumption, and a plastic burning odor inside the vehicle. The vehicle was taken to an authorized dealer, where the crankshaft position sensor was replaced; however, the failure persisted. The vehicle was taken to a second dealer, Kia Store Clarksville (826 E Lewis and Clark Pkwy, Clarksville, IN 47129), where Voluntary Service Campaign: SC334 (Service Brakes), Technical Service Bulletin: SA485 (ECM Logic Improvement), and Customer Satisfaction Program: CS2311 (Theft Deterrent Ignition Cylinder Protector & Decal Installation) were performed. The failure recurred, and the vehicle was taken back to the first dealer, who diagnosed that the catalytic converter had melted. The vehicle was then taken back to Kia Store Clarksville, where it was diagnosed that the catalytic converter had melted, the engine cylinders were scored, and the pistons had failed; however, no diagnostic trouble codes (DTCs) were retrieved as required for engine and catalytic converter replacement. The contact associated the failure with the federal safety agency Campaign Number: 19V120000 (Engine, Engine and Engine Cooling); however, the VIN was not included in the recall. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 139,500.

Component or system: Catalytic converter (exhaust emissions system). The converter is physically restricted due to substrate damage consistent with the defect identified in the federal safety agency Campaign 19V120 / Kia Recall SC176. The restriction limits engine RPM to approximately 3,000 under all conditions. The vehicle is available for inspection at any authorized Kia dealership. No DTC is stored because the restriction has not yet degraded catalytic efficiency below the ECU's threshold — the catalyst is still chemically functional but physically blocked. Safety risk: The RPM limitation prevents the vehicle from accelerating past ~3,000 RPM, creating a significant hazard when merging onto highways, passing in traffic, or climbing grades with risk of fire. The recall notice identifies the risk as "abnormal engine combustion and damage to pistons and possible piston connecting rod failure," which can result in sudden engine stall while in motion. The restriction is progressive and will worsen, increasing the likelihood of complete power loss. Reproduced or confirmed by a dealer: The vehicle was inspected at an authorized Kia dealer. The dealer scanned for DTCs, found none, and declined to perform the recall remedy (catalytic converter replacement) on the basis that P0420 had not been stored. The dealer confirmed catilitic converter was clogged.

I am filing a formal safety compliance complaint regarding my 2016 Kia Soul (1.6L GDI engine) and a structural failure of the exhaust/catalytic converter system related to the federal safety agency Campaign 19V120000 / Recall SC176. The vehicle has thrown a persistent P0420 Check Engine Code (Catalyst System Efficiency Below Threshold) and is experiencing unsafe driving conditions, including severe power loss and sudden engine stalling in active traffic. Authorized franchise Valley Kia of Modesto has refused to honor the safety recall framework. They have denied federal compliance by refusing to perform the mandated exhaust inspections, engine combustion tests, or hardware replacement under the open recall guidelines, falsely claiming prior software updates absolve them of replacing the failed physical hardware. Corporate Case #26299283 was opened on August 19, 2026, but the franchise continues to operate in complete non-compliance with federal motor vehicle safety standards, leaving an active fire and stalling hazard unresolved.

My 2016 Kia Soul with the 1.6L GDI engine lost power. On 08/21/2026 at 107,547 miles I took it to Grand Kia, 1950 West 104th Avenue, Thornton, Colorado, repair order 137483, service advisor Patricia Palmas. The dealer performed a cylinder compression test and a leak-down test and documented on the repair order that the engine has scored cylinder walls, with cylinder number 3 identified as the affected cylinder. They also performed a rod bearing clearance test, which passed. They pulled down the exhaust to inspect the downstream catalytic converter and recorded that inspection as okay. They noted new spark plugs with no signs of fouling. Despite recording scored cylinder walls on their own repair order, the dealer told me the vehicle was fine and took no further action. No diagnostic trouble code was present. I was not given a written reason for the refusal, no technical assistance or Techline case was opened that I am aware of, and no engine inspection under any campaign was offered. I was charged nothing and sent away with a vehicle that has documented internal engine damage. This vehicle is within the population covered by Kia safety recall SC176 (the federal safety agency campaign 19V120), which covers all 2012-2016 model year Souls with the 1.6L GDI engine. That recall describes a failure mode in which the catalytic converter is damaged by overheating, substrate particles enter the engine combustion chamber, and continuous abnormal combustion results in damage to one or more of the engine's pistons, which can cause connecting rod breakage and puncture the engine block, allowing oil to contact hot exhaust surfaces. The stated remedy includes upgrading the ECU logic, replacing the catalytic converter if damaged, and replacing the engine depending on the extent of damage. Scored cylinder walls on a single cylinder is consistent with the damage mechanism that recall describes. The recall states there are no restrictions on owner eligibility. Nevertheless, no evaluation under SC176

My 2016 Kia Soul is a 2.0L Gasoline Direct Injection engine. 1 prior recall for Kia Souls have occurred, which is seemingly identical to my issue. Recall SC176 addresses Kia Souls with the 1.6L engine, and it just so happens my issue is the same. Kia also issued a response to knock issues with the Soul 2.0L MPI engine, the KSDS Campaign, where Kia rolled out the Knock Sensor Detection System software update (Campaign SC200) to monitor for connecting rod bearing. I have the GDI so this was not available to me. The catalytic converter is damaged from piston corrosion. The engine hasn't been properly powering the car to allow it to accelerate, nearing stall from stop, and when trying to upshifting. Power loss combines with a regular whistling noise, and occasional knock noise. Kia has been having similar issues with their varying Soul models. They have attempted to limit the scope of what fixes they'll provide, but clearly the scope was not broad enough. The first symptom of this issue occurred several months ago, at which point I made an appointment asap with Kia, the soonest of which was almost 2 months later.
