Disadvantages of the Hyundai D4HE engine

  • This diesel engine appeared quite recently and there is no information about its breakdowns;
  • Capricious piezo injectors here have given way to more reliable electromagnetic;
  • Instead of timing chains, a belt is now used, let’s see what resource it will have;
  • It is not known how the new aluminum block will show itself during long-term operation;
  • Naturally, there is a particulate filter and an EGR valve, which will give us problems.
