2025 Hyundai Kona Problems: 3 Issues Every Owner Should Know
2025 model year · 380+ owner reports · Updated April 2026
According to Au7o's analysis of 380+ owner reports, the 2025 Hyundai Kona has 3 documented known issues, with 1 rated critical. The most serious is DCT Clutch Judder (1.6T) ($0-$2,500 repair). The most commonly reported issue is IVT/CVT Judder and Droning Noise with 380 owner reports. Across all issues, repair costs range from $0 to $4,000. DIY maintenance guides at au7o.io.
All 3 Known Issues
On the 2018-2025 Hyundai Kona 1.6T, the 7-speed dry dual clutch transmission (DCT) paired with the 1.6T engine in the Kona exhibits clutch judder, particularly from a stop and during low-speed driving. The dry clutch design is inherently sensitive to heat buildup in stop-and-go traffic, and the judder worsens as the clutch friction material wears unevenly. Hyundai has acknowledged the issue and extended the DCT warranty on affected model years.
Common Symptoms
- Shuddering from a stop
- Jerky low-speed driving
- Vibration during slow acceleration
- Hesitation when pulling away
- Clunking between 1st and 2nd gear
How to Fix
Check if your Kona is covered under Hyundai's extended DCT warranty (up to 10 years/120,000 miles). A TCM software update is the first step and can improve shift calibration. If judder persists, the dual clutch assembly needs replacement. Avoid creeping in traffic with the brake partially applied — come to a full stop instead to reduce clutch heat. Some owners report that the judder is worse on inclines.

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.

- UpgradeUse only Hyundai SP-CVT1 fluid - generic CVT fluid will damage the IVT chain (Hyundai SP-CVT1 Transmission Fluid)
- TipChange IVT fluid every 30,000 miles instead of the 60,000 mile interval to extend transmission life
On the 2019-2025 Hyundai Kona 2.0L, the Kona 2.0L uses Hyundai's IVT (Intelligent Variable Transmission), which is a chain-driven CVT. The chain and pulley surfaces can develop wear over high mileage, causing a whining or droning noise that increases with speed. As wear progresses, the transmission may slip, causing RPM flares without corresponding acceleration. The IVT fluid condition is critical to chain and pulley life.
Common Symptoms
- Whining noise that increases with speed
- RPM flares without acceleration
- Transmission slipping under load
- Droning noise at highway speed
- Hesitation during passing maneuvers
How to Fix
Change the IVT/CVT fluid every 30,000-40,000 miles using Hyundai SP-CVT1 fluid — do NOT use conventional ATF. If noise or slipping is present, have the transmission inspected by a Hyundai dealer. Early intervention with a fluid change can slow wear progression. Severe cases require IVT replacement or rebuild. Avoid aggressive driving habits and sustained high-RPM operation which accelerates chain wear.
