Disadvantages of the Hyundai D4HF engine

  • This diesel appeared recently and there are no statistics of its breakdowns.
  • Instead of capricious piezo injectors, simpler electromagnetic ones are installed here.
  • Timing chains have given way to a belt and, according to the regulations, check and inspect every 120,000 km.
  • It is not known how the new aluminum block will perform during long-term operation.
  • Quite typical problems with the particulate filter or the EGR valve are also expected.
