Disadvantages of the Hyundai G4FS engine
Reviews on specialized forums are generally positive, with the exception of the Start-Stop system.
It has carbon buildup on the intake valves, just like all direct injection engines.
Additionally, the timing chain does not have a very high resource for engines in this family.
