Strengths
Economical thanks to direct injection

Watch-outs
Demanding on fuel and oil quality
Connecting rod bearing spin is not uncommon
Frequent failures of the E-CVVT camshaft adjuster
Known engine issues
Connecting rod bearing spinIn all units of this series, connecting rod bearings are weak and spins are unfortunately not uncommon, especially in all-wheel drive vehicles and those who skimp on oil changes. Engineers tried to fix the situation and from 2011 to 2014 installed different bearings with ceramic coating. But their service life turned out to be even shorter, sometimes less than 50,000 km.
E-CVVT camshaft adjusterSince 2015, this engine has been equipped with an electric E-CVVT camshaft adjuster on the intake side, and in the first year dealers often replaced it under warranty due to oil getting under the cover. The carbon brushes, also located under this cover, have a modest service life.
Oil consumptionThese engines fairly quickly got oil jets for piston cooling, and problems with scoring due to catalyst debris entering are not common. The main cause of oil consumption here is sticking oil scraper rings.
Listed from most frequently reported, each with its source.
Carbon buildup on valves (direct injection)
Often reported
In the 1.6 T-GDi engine, carbon deposits can form on intake valves over time; this can cause sluggishness, power loss, and rough running.
Engine Internal
Abnormal oil consumption
Often reported
Italian owners and forums report cases of higher than normal oil consumption in the 1.6 T-GDi engine; more frequent oil top-ups are needed than expected.
Engine Internal
Premature timing chain and tensioner wear
Often reported
The 1.6 T-GDi 177 HP engine may show timing chain or tensioner wear warnings at relatively low mileages (sometimes a few tens of thousands of km). Metallic noise when cold is among the symptoms.
