Common Failure
Fuel injector failure and fuel pump issues have been subject to Technical Service Bulletins and recalls for 2022 Kona N models. TSB 24-FL-006H addresses GDI injector replacement due to misfire DTCs . A separate 2024 recall covers 54,000+ Hyundai N vehicles with 2.0L T-GDI engines for a fuel control valve defect in the high-pressure fuel pump that can cause stalling or loss of power . Hyundai issued a global recall on 2022-2023 Kona N models for this fuel pump issue . Rough idle, check engine light, and limp mode are common symptoms. Hyundai has revised the fuel pump part (post-October 2023) .
The Hyundai Kona N uses the same G4KH 2.0L T-GDI engine found in the i30 N and Elantra N. While this high-output turbocharged unit is generally robust, owners have reported several well-documented issues - including fuel system failures (injectors, high-pressure fuel pump) and knock sensor sensitivity. Rebuilt engines through EnginesMarket include upgraded components addressing the original failure points, plus a minimum 12-month unlimited-mileage warranty.
Fuel Injector and High-Pressure Fuel Pump Issues
Affected Vehicles
Hyundai Kona N (G4KH, 2021-2023)
Typical Failure Mileage
10,000-40,000 miles
Root Cause
The G4KH engine's fuel system has been subject to multiple recalls and TSBs. Internal injector filter breakage causes misfire DTCs (P0300-P0304) requiring full injector replacement under TSB 24-FL-006H . The high-pressure fuel pump's fuel control valve can fail, allowing excess fuel into the pump and causing rough idle, misfire, check engine light, and limp mode . Affected Kona N vehicles built between 2021 and 2023 are covered by recall .

Our Recommendation
Our Recommendation
If your Kona N develops misfire symptoms or a check engine light, check your VIN against the active recalls and TSBs first - many 2022 models are covered for injector replacement at no cost. If the vehicle is out of warranty or the fuel system failure has caused secondary damage (turbo, cylinder scoring, or contamination), a rebuilt engine with upgraded components and a 12-month warranty is strongly recommended over patching individual components. Given the Kona N's strong £25k+ used value, the replacement investment is well justified.
Don't Let Engine Failure Write Off Your Hyundai Kona N
The G4KH 2.0L T-GDI engine is the heart of your Kona N's performance. With fuel system and knock sensor issues well-documented, catching problems early is critical.

Hyundai Kona N Engine ReplacementFrequently Asked Questions
Question 1How much does a Hyundai Kona N engine replacement cost-
A Hyundai Kona N engine replacement typically costs £1,800-£2,800 for a used G4KH unit, £3,500-£5,000 for reconditioned, and £4,500-£6,500 for a rebuilt engine with 12-month warranty [ESTIMATED - comparable performance 2.0L turbo pricing]. Fitting costs add £500-£800 at an independent specialist.
- Used G4KH: £1,800-£2,800 supply-only
- Reconditioned: £3,500-£5,000 supply-only
- Rebuilt with warranty: £4,500-£6,500 supply-only
- Specialist fitting: £500-£800
Question 2What are the signs of fuel injector failure in a Hyundai Kona N-
Hyundai issued TSB 24-FL-006H for GDI injector replacement on 2022 Kona N models. Common symptoms include misfire DTCs (P0300-P0304), rough idle, and check engine light . If ignored, internal injector filter breakage can cause more serious engine damage.
- Check engine light with misfire codes
- Rough idle and hesitation
- Reduced power during acceleration
Question 3Is it worth replacing the engine in a Hyundai Kona N-
Yes - with used Kona N values at £25,000+ , a rebuilt G4KH engine at £4,500-£6,500 represents roughly 15-25% of the vehicle's current market value [ESTIMATED]. This is a financially viable investment versus scrapping a desirable N performance SUV.
- Kona N retains strong values (£25k+)
- Rebuilt engine: ~15-25% of vehicle value
- Replacement offers peace of mind with 12-month warranty
Question 4What's the difference between the Kona N and Kona N Line engine-
The Kona N uses the 280PS G4KH 2.0L turbocharged engine, while the Kona N Line is powered by a 1.6L turbo GDI engine producing approximately 190-200PS . The Kona N is the only variant with the high-output 2.0L T-GDI and 8-speed wet DCT shared with the i30 N.
- Kona N: 2.0L T-GDI (G4KH), 280-290PS, 392Nm torque
- Kona N Line: 1.6L T-GDI, ~190-200PS
Question 5How long does a Hyundai Kona N engine replacement take-
A Hyundai Kona N engine replacement typically takes 2-3 days at a specialist workshop. The G4KH 2.0L T-GDI engine is relatively accessible, but the performance nature of the Kona N means careful attention is required for the turbo system and 8-speed DCT mating.
- Supply-only: 1-2 days delivery
- Specialist fitting: 2-3 days workshop time
- Full turnkey replacement: 3-5 days total
Question 6Does the Hyundai Kona N have a timing chain or belt-
The G4KH 2.0L T-GDI engine in the Kona N uses a timing chain, not a belt. Hyundai's Theta II T-GDI engines have a generally robust timing chain design. Unlike some GDI engines where timing chain tensioner failure is common, the G4KH's chain is reliable - but regular oil changes with the correct specification are critical for timing system longevity.
- Timing chain - no scheduled replacement interval
- Regular 0W-30/5W-30 oil changes critical
- Timing chain tensioner inspection if engine noise develops
