NHTSA Complaint #11570913 — 2015 KIA SOUL

Starting in summer of 2021, I began to has acceleration problems with my car and a check engine light came on. It was undrivable so I took it to the closest mechanic I could make it to, Firestone. They found the catalytic converter to be the problem and I paid $1100 to replace it. Later in 2021, the catalytic converter went out again and I had to have the engine coil and spark plugs replaced. I took it back to Firestone to replace it under warranty. During 2022, the check engine light came on again and again it was the catalytic converter. I got it replaced under warranty again. During this replacement, Firestone let me know that my engine was the source of why the catalytic converter keeps going out. The compression was too low and the engine was causing the catalytic converter to overheat. I took it to the dealership to have it diagnosed to see what was wrong in the engine. They claimed to have run diagnostics in the entire engine and only found that the engine coil and spark plugs needed replacement. I had both of those things replaced already the year before. They did not identify any problems with the new catalytic converter or any other part of the engine. The check engine light came on and my catalytic converter has gone out again and caused me to lose acceleration on a one lane each way 60mph road on my way to work. I suddenly slowed way down and cars had to swerve around me. I pulled off onto a farm road to let traffic by and then had to hobble to AutoZone nearby with my hazards on to get my check engine light codes read. It came up that the cat converter was having issues. I looked up to see if my car had any recalls and none were found. I did find that there was a major recall for Kia souls 2012-2018s for some piece of the engine that was causing catalytic converters to overheat. Many individuals who had this recall done to their vehicles also had to have engine coils and spark plugs replaced based on a forum regarding this recall.
