Crankcase (pcv) problems of the 2013 Kia Motor Soul

The contact owns a 2013 kia Soul. The contact stated that after arriving at her destination and upon attempting to start the vehicle, the vehicle failed to start immediately. After starting the vehicle and driving at an undisclosed speed, the vehicle inadvertently lost all motive power. The contact was able to pull to the shoulder of the roadway, where the vehicle was able to restart. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who was unable to diagnose the failure. The vehicle was then taken to the dealer, who diagnosed failures with the vehicle's exhaust system, including the catalytic converter and pcv valve. After investigating the failure, the contact related the failure to NHTSA campaign number: 19v120000 (engine, engine and engine cooling), but the VIN was not included. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 145,000.

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.

The first issue is that the oil light does not come on properly. It would only flicker on occasionally when the oil level began to get low. This is scary to think about not being warned that your car is out of oil and continuing to drive, when the engine could seize. The real issue is that the car is consuming oil. I am going through a quart a week just to keep up. I drive 500-600 miles a week. Kia will tell you that adding oil in-between oil changes is normal. There is nothing normal about having to give it this much. The car is not smoking and the car is not leaking. I had it checked by my mechanic, and they replaced the pcv valve. They said this was a long shot, and the next step would be to replace the engine. The valve replacement did little to help the consumption of oil. I know there are other cars in kia's offering that have leaked oil into the pistons, I am thinking this could be one of them.
