Subject: Possible Design Flaw in Accelerator Pedal – Kia Soul 2015 Dear Kia/the federal safety agency Representative, I am the owner of a 2015 Kia Soul and would like to report a concern regarding the design of the accelerator pedal. I have observed that when the vehicle is turned on and in “Park” mode, the accelerator pedal can be easily pressed unintentionally simply by moving the foot slightly while seeking a more comfortable position. This appears to be related to the low and forward positioning of the pedal, combined with the soft sensitivity of the electronic throttle system. As a driver, I believe this design may lead to unintended acceleration in certain situations, especially if one is not fully aware of their foot placement. There also seems to be no sufficient space to the right of the brake pedal to rest the foot without nearing the accelerator. While I have not experienced an incident as a result, I believe this characteristic may pose a safety risk to some drivers and could become a distraction either while driving or while the engine is idling. I respectfully request that this matter be reviewed by Kia’s technical team and, if appropriate, considered for design revision or future updates. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving my 2015 Kia Soul along a 4 lane highway when the Check Engine light came on and begun to flash. The Kia began to lose about 5 mph off and then return to the previous rate of speed a few minutes later. Then it would repeat the cycle. As the vehicle lost the engine power, the steering also became very tight as if the power steering was also malfunctioning. I could also hear a slight tapping sound, as the driver side window was open just a few inches. Since I had my mother whom is ailing with dementia and heart problems, I tried to remain calm and undisturbed by these issues. As soon as I arrived at the closest auto parts store that offered diagnostic readings (O'Reilys), I asked them to see what codes the vehicle was throwing. The codes were P0420 Catalyst System Efficiency Below Threshold (Bank 1) and P1326 Knock Signal Range/Performance. I have seen these codes listed as recalls for other 2015 Kia Souls, but for some reason my VIN is not listed amongst those. So how do I get this repaired?? This car is extremely important and sentimental to me, as it was the vehicle my son drove before he passed away at [XXX]. Please, please help me keep this Kia running.

Description of Incident: The engine has experienced a failure that causes oil to blow back from the engine, covering components both under and outside of the engine cover. This has resulted in oil accumulating on the exhaust and other hot components, creating a significant fire hazard. Safety Risks: This malfunction poses a serious risk to my safety and the safety of others, as the oil leakage could lead to a fire while driving. Additionally, the vehicle stalls at various speeds, which increases the risk of accidents or harm to other drivers and pedestrians. There is also a strong smell of oil inside the car, potentially indicating harmful fumes entering the cabin. Inspection Availability: The component/system causing the issue is available for inspection upon request. Reproduction and Confirmation of the Problem: The issue has been reproduced and confirmed by two SAE-certified mechanics. Inspection by Others: The vehicle has been inspected by two SAE-certified mechanics but not yet by the manufacturer, police, or insurance representatives. Warning Signs Prior to Failure: Warning signs included consistently losing oil even after a fresh oil change, smoke from under the hood, a strong oil smell inside the cabin, and the car stalling during operation. These symptoms have been ongoing and progressively worsening, with the vehicle now stalling more frequently.

My catalytic converter failed just under 4 years after getting the SC176 recall done in July 2020. I believe it's possible there was a step missed in the replacement of my catalytic converter related to the recall, specifically the Catalytic Overheating Protection Engine Control Unit logic that may have caused the converter to fail. I do not detect that on the attached receipt from the repair that was done for the recall. Although there were no safety issues that happened, after reading the recall and what can happen as a result of the catalytic converter failing, I am concerned for my safety if I drive it any longer in that condition. The problem has been diagnosed by my local Kia dealership on Friday 4/19/24 and that is where the car is presently. I have attached the inspection report and the cost to fix it. The vehicle has not been inspected by anyone other the Kia dealership. There was a ticking sound when I accelerated that wasn't there before on 4/3. The service engine light came on Thursday 4/4 when I was getting my routine oil changed. I changed the PCV valve and the light went off until approximately 4/17 and then I called the dealership to schedule bringing it in for the diagnosis which was 4/19. This is the only information I have at this time. Any help you can provide will be greatly appreciated.

My 2015 Kia Soul recently went out of service. One day last month my car randomly started stalling and shaking to the point of barely being drivable. There were no signs or dashboard lights. Thursday, September 15th, 2022, I took my car to a local repair shop and they ran a diagnostic that came back as a bad Catalytic Converter on Friday, September 16th, 2022. According to the mechanic, the converter nearest the engine had broken off and pieces of it had gotten into my engine and fuel line resulting in a need for a new converter and a complete engine flush. The mechanic pulled up a recall and suggested that the car be taken to the dealership as this particular issue should have been covered under that recall. He suggested that I no longer drive the car prior to getting it repaired for my and my children's safety as my engine could have blown up at any time and caught fire. Also on Friday, September 16th, 2022, I had the vehicle towed to the Kia dealership in Napleton Mid Rivers as advised by the mechanic. The car was towed to the dealership where I made them aware of the issue and I was advised they would have to perform a second diagnostic to confirm. Monday, September 19, 2022, I get a text message from Dennis Gearhart, a service advisor for Kia - who informs me that their diagnostic came back showing that I need a replacement Catalytic Converter, oil change, and minor tune-up. Dennis advised me that the repair would cost over $2800 and would not be covered under the recall because I'm no longer under warranty and the recall was marked as done. Upon further questioning - I was advised that the service advisor in May 2019 did NOT perform a replacement under the recall because it "didn't need it" yet here I am less than 7 years after getting a new engine from KIA and I'm being told to rectify an issue they were responsible for fixing and yet refuse to mitigate. They placed my and my family's life in danger due to the negligence of their staff!
