On the 2020-2023 Kia Soul 2.0L Nu MPI, the 2.0L Nu MPI engine in 2020-2023 Souls may have incorrectly manufactured piston oil rings that do not properly scrape oil from the cylinder walls. This causes excessive oil consumption, potential oil starvation, and eventual engine damage. NHTSA recall covers approximately 137,000 Soul and Seltos vehicles. Kia dealers install PNSS (Piston-ring Noise Sensing System) software and replace the engine if damage is found.

This issue also affects: Audi Q7, BMW 1 Series, BMW X6

Common Symptoms

Oil level drops rapidly between changes
Blue or gray smoke from exhaust
Engine knocking or ticking noise
Low oil pressure warning light
Rough idle or misfires due to oil fouled spark plugs

How to Fix

Check VIN for recall eligibility at owners.kia.com. Dealer will install PNSS software to detect abnormal engine noise from piston ring wear. If oil consumption exceeds 1 quart per 1,000 miles or engine noise is detected, the engine is replaced free of charge. Monitor oil level weekly between changes.
