All 4 Known Issues
The Sportage shares the same Theta II engine family as the Optima and Sorento, and is subject to the same manufacturing defect causing metal debris to remain in crankshaft oil passages. This leads to oil starvation, bearing wear, and potential engine seizure. NHTSA Recall 17V-224 includes affected Sportages. Kia extended the powertrain warranty to 10 years/120,000 miles and deployed the KSDS software update.
Common Symptoms
- Engine knocking or ticking that worsens over time
- Check engine light with rod bearing codes
- Excessive oil consumption
- Oil pressure warning light
- Metal debris found in oil during changes
- Sudden engine stall
How to Fix
Check VIN at owners.kia.com/recalls for extended warranty eligibility. Have dealer perform KSDS software update. If knocking is present, dealer will inspect rod bearings and perform oil consumption test. Engine replacement under extended warranty if failure is confirmed.

Certain 2023-2024 Sportage vehicles have an electronic controller in the Idle Stop & Go (ISG) oil pump assembly that may contain damaged electrical components. The damaged components can cause the oil pump to overheat, increasing the risk of a vehicle fire. NHTSA Recall 23V-578 covers affected vehicles. Kia dealers replace the ISG oil pump assembly.
Common Symptoms
- Burning smell from engine bay
- Check engine light
- Oil pressure warning
- ISG system malfunction warning
- Engine stalling during restart after idle stop
How to Fix
Check VIN for Recall 23V-578. Dealer will inspect and replace the ISG oil pump assembly free of charge. Until the recall is completed, some owners disable ISG via the dashboard button to reduce risk.

The Hydraulic Electronic Control Unit (HECU) in the ABS brake module can develop an internal electrical short, causing overheating and potential engine compartment fire. This can occur while driving or while the vehicle is parked. NHTSA Recall 18V-743 and subsequent recalls cover affected Sportages. Kia installs a lower-amperage fuse and inspects the HECU for damage.
Common Symptoms
- ABS warning light illuminated
- Burning or electrical smell from engine bay
- Smoke from engine compartment area
- Vehicle fire
How to Fix
Check VIN for recall eligibility immediately. Dealer replaces the HECU fuse with a lower-amperage unit and inspects the HECU assembly. If leakage or thermal damage is found, the entire HECU is replaced free of charge. Park outside and away from structures until repair is complete.

AWD Sportage models (4th generation 2017-2022) develop worn rear differential mount bushings that cause a clunking noise from the rear when accelerating from a stop or transitioning between acceleration and deceleration. The rubber bushings deteriorate and allow excessive differential movement. This is particularly noticeable in cold weather and with higher mileage (60,000+ miles).
Common Symptoms
- Clunk from rear when accelerating from stop
- Thud noise during acceleration/deceleration transitions
- Vibration felt through floor at highway speeds
- Noise worse in cold weather
How to Fix
Replace rear differential mount bushings (Kia part #55277-D9000). Some owners upgrade to polyurethane bushings for longer life. Labor involves lowering the rear subframe and is approximately 2-3 hours at a shop. DIY-friendly with a lift and basic tools.
