Known issues and risks

Listed from most frequently reported, each with its source.

Carbon buildup on intake valves

Often reported

The 2.0 SKYACTIV-G engine uses direct injection, so fuel does not clean the intake valves, leading to carbon deposits that cause power loss, rough running, and hard starting.

Engine Internal

Oil consumption and leaks related to PCV system

Often reported

Some SKYACTIV-G 2.0 owners report increased oil consumption or local leaks (e.g., valve cover gasket) and issues with the crankcase ventilation system (PCV valve). A clogged or faulty PCV system can increase internal pressure, leading to leaks.

Engine Internal

Clogged injectors / hesitation and misfires

Often reported

Owners report hesitation, minor misfires, or uneven fuel delivery that is resolved by replacing or cleaning the injectors.
