Nu 2.0 GDI (G4NC) vs G6DP 3.3 V6 TT
Side-by-side reliability comparison

Character
Nu 2.0 GDI (G4NC)
"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."
G6DP 3.3 V6 TT
"Hyundai/Kia's 3.3 twin-turbo V6 (Lambda II, from 2016) with direct injection and a timing chain: 366 PS in the European Kia Stinger GT, also used in Genesis models. Strong and smooth. The one documented fault is the left turbocharger oil feed pipe, which can perish and leak oil onto hot parts; a worldwide recall (Europe 241039, US 24V-169) replaces it free of charge. Check the recall is done. Long-term data beyond that are still thin."
