Disadvantages of the Hyundai G4FP engine

  • Unknown about the reliability of the new CVVD variable valve timing system;
  • The turbine is new here and we hope that it will not drive oil on low runs;
  • Due to the direct fuel injection system, the valves are very quickly overgrown with soot;
  • Since hydraulic lifters did not appear and the valves will have to be adjusted.

    My European Tucson has the G4FU engine which is the 1.6 T-GDI 48V MHEV. Could you please include it? Thank you.
