U 1.1 CRDi (D3FA) vs G6DP 3.3 V6 TT
Side-by-side reliability comparison
Specifications
Character
U 1.1 CRDi (D3FA)
"Three-cylinder 1.1 CRDi diesel (2005-2019) from the Hyundai/Kia U family, used in the Kia Picanto, Hyundai i10 and i20 and Kia Rio. 75 hp, Bosch common rail, very low fuel use. No widespread serious fault is documented; the main costs come from soot clogging the EGR valve and intake swirl flaps in town driving, and early engines can push oil into the intake through the crankcase breather. Owners report 290,000 km and more. Evidence is limited, so the score is capped."
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."
