2016 KIA Soul problems

ENGINE

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.

ENGINE

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

Engine block had been replaced due to recall and excessive oil consumption, but vehicle is doing this again. Local dealership refuses to give appt for oil check and is sending us 55 miles away. We’re told it will be about 1k to test it for fuel combustion and oil change before they can even test it. Replacement engine block failed to fix the issue and local Kia is not helpful.

ENGINE

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.

Check engine light came on and car was out of oil even though an oil change was done about a month ago. Catalytic converter was replaced once already. Per mechanic excess heat caused out to leak catalytic converter needs replacing again and now engine is damaged as all engine oil leaks out where it cannot be detected on ground. Danger of fire according to recall sc176 and mechanic. Car was smoking so it has been parked for safety to avoid fire

POWER TRAIN

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.

We would like to file a complaint and request a recall so that Kia Corporation is responsible to pay for a new paint job on our vehicle, 2016 Kia Soul. With Kia Corp, paint is covered under warranty for 3 years, however a customer would not know there is a paint adhesion problem within the first 3 years. The problem - Our paint is peeling off of the vehicle and started out of nowhere, no rock chip...nothing. It started as a bubble on the side of our vehicle and that bubble broke open and began peeling. We also have areas SEPARATE from the original area that just randomly flaked off with no bubble...just started peeling from the edges of the window, especially on top of the roof. No matter where it starts (and it continues to do so), it peels on its own. We have a white Kia and white (amongst a few other colors) seems to be an issue from KIA's manufacturer. Kia knows it. It seems the mfg used the incorrect paint adhesion product from the beginning, therefore it is peeling off. We've never seen anything like it. We currently have 77K miles on the car, but this started a year ago. We just had no idea this first, tiny area would turn into the entire car's paint peeling off. This is a manufacturing issue. The vehicle peels to the gray level first and then to a mustard color, so we are down to the original metal. This is all without us touching it at all. It peels ON ITS OWN. I have called Kia customer care to see what is wrong with the Kia Soul. The first time, KIA's customer care rep did not log it as a case number, so there is no record of my call. The 2nd time, calling on 6/15/26, I had to request to file a complaint so that a case number was created. I am now filing a complaint with NHTSA. Please see photos. Thank you for your consideration, [XXX] and [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

STRUCTURE:BODY

UNKNOWN. See my statement below. I also have pictures I will upload. My vehicle is suffering from Severe factory paint and clear coat delamination on the vehicle's flat surfaces (hood and roof and now starting on the door handles and mirrors), resulting in total material deterioration down to the bare primer and exposed underlying metal sheet. This vehicle has been driven only 63,000 miles, has been impeccably serviced entirely at authorized Kia dealerships on schedule, and has suffered no accidents or body modifications. The factory finish has completely dissolved, exposing the bare structural metal of the roof and hood to rain and heavy humidity. This structural exposure presents an imminent safety risk of premature body panel corrosion, structural rust degradation, and potential panel perforation, which will compromise the structural integrity of the cabin and roof in a collision. Furthermore, this clear coat failure has been visually documented on multiple identical 2016 Caribbean Blue models in my immediate geographic area, confirming a widespread chemical bonding defect at the manufacturing plant. I have color photos I will uplaod of my vehicle sitting next to an identical 2016 Kia Soul, the same paint color, that has the same paint issues. That's when I first realized this must be a factory issue when the vehicle was manufactured. I have since discoverd many customers complaining on the Internet about the same issues with their 2016 Kias, proving once again this was an issue that happened at the factory but was never recalled by Kia North Amercia. I am in the process of writing Kia North America requesting a Goodwill paint job for my vehicle. I will be including all service records, vehicle registation, numerous color photos of the vehicle as well as a copy of the original sticker on the vehicle when I purchased it new. I am requesting that the NHTSA you open a case concerting my issue.

ENGINE

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.

SERVICE BRAKES

I reported to Kia regarding 2016 KIA Soul EV electronic gear shift and power system as follows. "I am writing to formally report a serious safety concern regarding the electronic gear shift and power system on my Kia Soul EV. I have experienced several dangerous incidents involving the vehicle's behavior when parking on an incline. Specifically, if the vehicle is parked on a slope and the power switch is turned off while the gear selector is still in 'Drive' (D), the control power shuts down immediately, and the vehicle begins to roll down the hill because it does not automatically engage 'Park' (P) or the electronic parking brake. While I understand the importance of manually selecting 'Park,' it is common for electronic shifters in modern EVs to automatically shift to 'Park' or engage a safety brake when the power is turned off to prevent such hazardous rolling. The current logic poses a significant safety risk to the driver, passengers, and bystanders. I would like to know if there is a software update available to address this logic or if Kia has a recommended safety protocol to mitigate this risk. I look forward to your prompt response regarding this matter." and received email from KIA "After reviewing your concern, we can confirm that at this time there are no updates, recalls, or service campaigns related to the parking logic or automatic engagement of Park or the parking brake for the condition you described. We recommend reviewing the Parking Brake section of your Owner’s Manual (Section 5, Page 25), which outlines the designed operation and proper procedures when parking the vehicle, particularly on an incline." Please review this case and find resolutions for this safety issues. Thank you
