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.
