All about the Hyundai Tucson (NX4)All about the 1.6 T-GDi (Hyundai-Kia Gamma turbo) engine
The 1.6 T-GDi (Hyundai-Kia Gamma turbo) engine was fitted to the Hyundai Tucson (NX4) (2020–now). In the EU that is 92.5 % of all new cars of this generation.
Versions: 1.6 179 hp, 1.6 150 hp, 1.6 160 hp, 1.6 159 hp, 1.6 136 hp.
The most expensive known risk is high oil consumption (piston rings), can damage the catalyst: it usually appears at 70,000–180,000 km and costs €300–4,000 to fix.
✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Signs: Oil level drops between services, low oil warning, blue smoke, later P0420 catalyst code
Fix: Check the level every refuel and do a documented consumption test; shorten oil changes to about 10,000 km; rings or short block if consumption is high, then check the catalyst
Signs: Rough idle, hesitation, misfire when cold, slight loss of power
Fix: Inspect the valves with a scope and clean them (walnut blasting); sprays give little result
Signs: Engine light, boost fault codes (e.g. P2562/P2563), sudden loss of power or limp mode, rattle from the turbo
Fix: Check the actuator and the wastegate linkage for carbon and free play; adjust or replace the actuator, the turbo only if it is damaged inside
Signs: Oil traces around the turbo and its lines, burning smell after a drive
Fix: Replace the line seals and tighten or renew the banjo bolts; the turbo itself is usually fine
Signs: No warning sign; a wrongly fitted curtain airbag may not cover the window area properly in a crash.
Fix: Check the VIN for the open recall; the dealer inspects the curtain airbag and replaces it if needed, free of charge.
Signs: Warning message and reduced brake assist (hard pedal) if the pump drive is damaged at engine start.
Fix: Check the VIN for the open recall; the dealer updates the engine control unit software (about 30 min), free of charge.
Signs: Rear power window motors may malfunction and the window may not stop or reverse when something is trapped.
Fix: Check the VIN for the open recall; the dealer replaces both rear window motors, free of charge.
Signs: No warning; the tie rod joint can come loose and steering control can be lost.
Fix: Check the VIN for the open recall; the dealer replaces both tie rod ends, free of charge.
Signs: Screen freezes, reboots or navigation misbehaves.
Fix: Ask the dealer for the latest infotainment / navigation software update; replace the unit only if updates do not help.
Signs: Slipping, high bite point
Fix: Replace clutch kit
Signs: Shudder or jerks pulling away in 1st / 2nd and in reverse, harsh 1-2 / 2-3 shifts, 'transmission overheating' message in stop-and-go traffic or on hills
Fix: Have the dealer update the gearbox software, reset the clutch adaptation and measure clutch wear; replace the double clutch if worn
Signs: Delayed or harsh shifts
Fix: Fluid service, repair
Typical routine maintenance cost for 100,000 km: €2,200–4,950. Sum of the services and wear parts in the plan above (about 15,000 km a year, independent workshop), without faults.
