2016 Kia Soul Engine Problems

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)

My 2016 Kia Soul 1.6L GDI has an unresolved engine-related safety and recall concern. The vehicle is associated with safety recall SC176 / NHTSA 19V120, which remains identified as incomplete in the vehicle’s recall records. Kia also sent a recall renotification stating that the recall had not been completed. The vehicle was taken to an authorized Kia dealership after experiencing engine knocking, difficulty accelerating, and a no-start condition. Repair Order #544458 documents the reported engine knocking, trouble accelerating, and inability to start. The repair order also states that the vehicle was towed out because Kia Techline declined the engine request due to related recall work not having been performed. The vehicle was released without the requested engine replacement or a completed resolution. The concern is that the vehicle experienced serious engine-related symptoms while an applicable safety recall was listed as incomplete, and the manufacturer’s authorization process did not result in a completed recall-related remedy. The vehicle was subsequently removed from the dealership. I request that NHTSA document and review this complaint, including whether the recall remedy and engine-related concerns are being appropriately addressed. The vehicle and supporting records may be available for inspection upon request. Supporting documentation includes the Kia recall letter, recall verification, dealership repair order, and communications concerning the manufacturer’s review.

The engine long-block assembly suffered a catastrophic, terminal internal collapse and sudden stall due to abrasive substrate particle ingestion from a previously failed, melted manifold catalytic converter under Safety Recall SC176 (NHTSA Campaign 19V120000). The vehicle has been extracted to preserve evidence and is available for immediate physical inspection. The vehicle suffered a complete, sudden loss of motive power and stalled while traveling at high speeds on a busy public highway. It went into an un-accelerated limp mode, creating an immediate hazard of a high-speed rear-end collision on the highway shoulder. Authorized franchise facility Garden Grove Kia officially confirmed the terminal block failure under Repair Order #6238999. A diagnostic scan confirmed multi-cylinder misfires (P0300–P0304). A physical compression test confirmed a terminal drop to 59.6 psi in Cylinder 2, and an internal camera borescope confirmed a catastrophic internal Cylinder 2 wall crash damage not sealing alongside a fractured spark plug tip inside Cylinder 4. The dealership officially recommended a total engine replacement. The vehicle was inspected by a certified franchise dealer technician representing the manufacturer. A formal enforcement case has been opened regarding this vehicle asset and documentation file with the California Bureau of Automotive Repair (BAR) under Reference Case #669B-C5PDRP

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 NHTSA 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.

My car is under 130000 miles and about two years ago I already had to replace one catalytic converter. The past six months the oil usage of my car, which has always been high and requires frequent topping off and more frequent oil changes at my mechanic, has gotten even worse. A check engine light came on a few weeks ago due to a catalytic converter fault. While car is still functional my mechanic expects the second converter will have to be replaced soon. These are all signs of an engine and system that is not functioning properly and could cause an issue at any time.

On December 4, 2025, I presented my vehicle to Kia Carriage of Woodstock with the following symptoms: • Continuous check‑engine warning • Rattling engine noise • Oil leakage • Strong burning‑oil smell while driving These symptoms are consistent with rod bearing failure, a known Kia safety defect covered under the extended warranty and KSDS settlement. Kia’s own records confirm: • KSDS update completed on 4/10/2021 • Vehicle qualifies for the 15‑year / 150,000‑mile extended warranty • Rod bearing failure requires full engine replacement under warranty Despite this, the dealership refused warranty coverage and attempted to charge me $6,000 for an engine replacement, while also charging $300 for a diagnostic that did not resolve or address the safety issue. --- Dealer Misconduct and Warranty Avoidance Kia Carriage of Woodstock engaged in the following misconduct: • Refused to honor the extended warranty • Returned the vehicle in unsafe condition • Attempted to upsell me into purchasing another vehicle • Sales manager admitted the car “was not pumping oil” and that this was “a Kia problem” • Still refused warranty repair This behavior is predatory, unsafe, and violates Kia’s warranty obligations. --- Consumer Affairs Contradictions and Failure to Escalate On August 11, 2026, I opened Case No. 263276699. On the phone, a Consumer Affairs representative initially confirmed my vehicle is under warranty. After I referenced the denial letter I received, the representative changed her position and stated the rod bearing failure “is not covered,” citing a “multi‑point inspection” from December 2025. A multi‑point inspection does not diagnose rod bearing failure and cannot be used to deny warranty coverage. Consumer Affairs has: • Provided contradictory information • Refused to escalate the case • Relied solely on the dealership’s statements • Failed to address a clear safety hazard This is unacceptable and requires executive intervention. --- Current Statu

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 NHTSA 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 (NHTSA 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.

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle is a 2016 Kia Soul 1.6L GDI with approximately 83,000 miles. The vehicle experienced engine performance issues, loss of power, and stalling. A Kia dealership diagnosed a failed/melted catalytic converter and reported metal shavings in the engine oil. The vehicle has not been repaired and is available for inspection upon request. How was your safety or the safety of others put at risk? The vehicle stalls and loses power, creating a safety hazard while driving in traffic. A sudden loss of power increases the risk of being struck by another vehicle and makes it difficult to safely maintain speed, merge, or cross intersections. Because the vehicle is unreliable and may stall unexpectedly, I do not consider it safe to operate. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The condition was confirmed by an authorized Kia dealership. The dealership diagnosed a clogged/melted catalytic converter and reported metal shavings in the engine oil. The dealership advised that the catalytic converter must be replaced before they would perform further engine diagnosis. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by an authorized Kia dealership. Kia Customer Care was notified of the issue and reviewed the claim but declined assistance. To my knowledge, the vehicle has not been inspected by a Kia field engineer, police agency, or insurance investigator. Were there any warning lamps, messages, or other symptoms prior to the failure, and when did they first appear? Yes. The vehicle experienced drivability issues, loss of power, and check engine light illumination. Diagnostic trouble codes reported included P0420, P2191, and P2196. The symptoms progressively worsened and eventually resulted in severe performance issues and stalling.

My 2016 Kia Soul (1.6L GDI engine) experienced a catastrophic, sudden engine failure while driving, preceded by Check Engine Light code P0420 (Catalyst System Efficiency Below Threshold). This exact failure sequence is the precise subject of active NHTSA Safety Recall Campaign 19V120 (Kia Campaign SC176).Although the vehicle received the mandated SC176 preventative software update in 2019, the underlying mechanical defect was not cured. High exhaust gas temperatures caused the catalytic converter to degrade and fracture internally. The fractured abrasive substrate particles were then siphoned backward into the engine combustion chamber during normal valve operation. This caused immediate, severe scoring of the cylinder walls and piston damage, leading to total engine seizure and failure. This defect presents an extreme safety risk. Sudden engine failure at highway speeds causes an immediate loss of motive power, braking assistance, and power steering, significantly increasing the risk of a high-speed collision. Furthermore, fractured connecting rods or oil leakage stemming from this specific engine failure pose a severe vehicle fire hazard. The vehicle is currently held for diagnostic verification at Kia Riverside in California. I am filing this complaint because the manufacturer's 2019 software remedy was entirely ineffective at preventing the mechanical destruction of the engine and catalytic converter. I am requesting that the NHTSA hold Kia accountable to fulfill the physical repair and replacement mandates of Recall SC176 at zero cost to the consumer, regardless of the prior software logging.

The vehicle is burning oil. It creates residue in my engine which may make it dangerous to drive and ruin the catalytic converter, among other issues. I was first notified of this problem during my second oil change in 01/2026 at a Kwik Kar Lube & Tune, about 6 months after purchasing the vehicle in 06/2025. As of 05/2026, an oil warning lamp began to appear on the vehicle dashboard to notify me that the oil was low. I checked the oil stick, and there was burnt oil, albeit very little of it. I had gotten a full synthetic oil change, so it was not yet time to change my oil, but clearly this issue is causing premature oil loss.

I am reporting a safety concern related to NHTSA Recall 19V120 involving my Kia Soul. The recall identifies a defect related to catalytic converter overheating, which can lead to engine damage, stalling, and increased risk of fire. My vehicle is currently experiencing an illuminated check engine light and unsafe driving conditions. During service evaluation at Kia of Columbus, I was informed that my vehicle has a catalytic converter blockage contributing to these issues. However, I was also told that my vehicle does not qualify for recall repair because no engine code was detected during diagnostics. This is concerning, as the vehicle is actively exhibiting symptoms consistent with the recall condition, including a confirmed catalytic converter issue and an illuminated malfunction indicator lamp. Despite this, I was denied full recall coverage and instead offered a goodwill repair requiring me to pay 50% of the cost. I believe this situation represents a failure to properly apply recall criteria and raises concerns regarding customer safety, as the vehicle may be at risk for engine failure or fire. I am requesting further review of this matter and investigation into the handling of this recall by the servicing dealership.
