Nu 2.0 GDI (G4NC)
Hyundai/Kia · 2.0L GDI I4
2011–2020
"Direct-injection 2.0 used mainly outside Western Europe (Tucson, Sportage, i40, Elantra, Soul). Its known fault is connecting-rod bearing wear: Hyundai and Kia recalled US cars, added knock-sensor monitoring software and a 15-year engine warranty there, and at least 45 Tucsons caught fire. European guides rate the i40 2.0 GDI as durable. Buy only with service history; a knock or the oil light means stop driving."

Known Issues 2
Connecting-rod bearing wear — knock, seizure, fire risk (US recalls)
▸Knocking from the bottom of the engine, oil-pressure or low-oil warning light, check-engine light, loss of power, burning smell or smoke; on US cars with the update, a blinking engine light, code P1326 and a limp mode capped at about 2,000 rpm
Hyundai and Kia recalled US 2014-2017 Nu 2.0 GDI cars (20V-746, 20V-750, 21V-727) because the engines may have been built with conditions that cause premature connecting-rod bearing wear; a damaged rod can puncture the block and start an oil fire. At least 45 fires on 2017 Tucsons. The fix is an inspection, a new engine if the bearings are damaged, and knock-sensor monitoring software, plus a 15-year/150,000-mile engine warranty in the US. The same engines are part of the In re Hyundai and Kia Engine Litigation II settlement alongside the Theta II MPI. NHTSA estimates 1% of the recalled population is defective. One owner was quoted USD 7,800 for a replacement engine (approx. EUR 7,200, converted).
The US warranty and recall do not apply to European cars. A Nu 2.0 GDI in Greece is most likely a grey import - check service history, listen for knock on a warm idle, and walk away from any car with an oil-pressure light history.
Intake carbon and coked injectors (direct injection)
▸Rough idle, hesitation, higher fuel consumption
A German used-car guide rates the i40 2.0 GDI as durable with regular servicing but warns that, as a direct-injection engine, it builds carbon in the intake tract and cokes its injectors. No cost or mileage in any source.
Short city trips speed this up; use branded fuel. No Greek-specific data found.
