All 1 Known Issues
On the 2018-2025 Hyundai Kona 2.0L, the Kona with the 2.0L engine uses Hyundai's IVT (Intelligent Variable Transmission, a chain-driven CVT) that can develop juddering at low speeds and a droning noise at highway speeds. The transmission fluid degrades faster than expected, and the chain and pulleys wear. TSB 21-AT-005 addresses judder concerns.
Common Symptoms
- Juddering at 15-30 mph
- Droning noise at highway speed
- Hesitation when accelerating
- Transmission slip feeling
- Vibration during light acceleration
How to Fix
IVT fluid change with Hyundai SP-CVT1 fluid can resolve mild judder. For persistent judder, the valve body may need replacement or software recalibration. Fluid change costs $150-250. Valve body replacement costs $800-1,400. Full transmission replacement is $3,000-4,500 if wear is severe.
