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

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

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

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

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
