NHTSA Complaint #11452613 — 2013 KIA SOUL

Purchased used 2013 Kia Soul July 2018. June 2019, vehicle was taken to Kia Dealership for SC176-19V120 ECU Logic Upgrade. Neither catalytic converter nor engine were replaced during recall repair. In 2020, vehicle began consuming oil and poor mileage. No smoke or leak detected. Had vehicle inspected by local mechanic, who could not find pooled oil or a leak. Suggested replacing PCV valve and had that done, but symptoms persisted. April 2021 Engine Misfire Code P0300 and P0303 for cylinder 3 and multiple cylinder misfires detected. Local mechanic also checked for burning oil or leaks. Engine made knocking sounds on acceleration. Mechanic performed fuel system cleaning, and replaced spark plugs and coils. Engine knocking stopped, but loss of oil and poor mileage remained. Oct 2021 Campaign PI2002A Knock Sensor software update to ECU was performed by local Kia dealership with no other repairs performed. Feb 2022, visible oil leaking from beneath car and check engine light. Local mechanic diagnosed CodE P0420 Catalyst System Efficiency Below Threshold (Bank 1), and heard engine knocking. Recommended replace catalytic converter and reprogram ECU for short term fix, followed by engine replacement due to wear and damage from catalytic converter. Suggested I contact dealership who performed recall repairs to see about warranty or replacement of engine due to recall repairs failing to correct faulty engine issues.
