All 4 Known Issues
The 2.0L Nu MPI engine in 2021-2023 Seltos vehicles has piston oil rings that may not have been properly heat-treated during manufacturing. The defective rings fail to scrape oil from cylinder walls, causing excessive oil consumption that can lead to oil starvation, bearing damage, and engine fire. NHTSA recall covers approximately 53,635 Seltos vehicles. Kia installs PNSS software and replaces the engine if damage is found.
Common Symptoms
- Rapid oil level drop between changes
- Blue smoke from exhaust
- Engine warning light
- Low oil pressure warning
- Engine knocking or rattling sounds
- Burning oil smell
How to Fix
Check VIN for recall eligibility at owners.kia.com. Dealer installs PNSS (Piston-ring Noise Sensing System) software to detect early engine deterioration. If oil consumption exceeds threshold or engine damage is detected, complete engine replacement is performed free of charge. Monitor oil level at every fuel fill-up.

The Seltos equipped with the 2.0L engine and CVT (IVT) exhibits hesitation, jerking, and poor acceleration response, particularly when merging or climbing hills. The CVT struggles under load and can enter limp mode. Owners report the transmission feels sluggish compared to traditional automatics. Kia has released TCU software updates to improve response.
Common Symptoms
- Hesitation during acceleration from stops
- Jerking or surging at low speeds
- Poor acceleration when merging onto highway
- Transmission enters limp mode under heavy load
- Rubber-band effect during passing maneuvers
How to Fix
Have dealer perform TCU software update (latest calibration addresses hesitation). If CVT fluid has not been changed, a fluid service with genuine Kia CVTF may improve response. For persistent issues, CVT replacement under powertrain warranty (10 years/100,000 miles). Some owners find that using Sport mode improves daily driving feel.

The Seltos instrument cluster intermittently fails to illuminate on initial startup, displaying a completely blank screen. Speedometer, tachometer, fuel gauge, and warning lights are not visible. The issue typically resolves after turning the vehicle off and restarting, but can recur. Some owners report it happens after extended driving followed by a short stop. A software update has been released to address the issue.
Common Symptoms
- Instrument cluster completely blank on startup
- No speedometer, tachometer, or fuel gauge display
- Warning lights not visible
- Issue resolves after restart
- Occurs intermittently, especially after short stops
How to Fix
