The 2.2-liter Hyundai-Kia D4HC or 2.2 CRDi diesel engine has been produced since 2017 and is installed in a range of rear-wheel drive models such as the Kia Stinger or Genesis sedans. This motor is a modification of the D4HB for cars with a longitudinal engine.
The R family also includes diesels: D4HA, D4HB, D4HD, D4HE and D4HF.
The engine was installed on:
- Genesis G70 1 (IK) since 2017;
- Genesis G80 1 (DH) in 2018 – 2020;
- Kia Stinger 1 (CK) in 2017 – 2020.

Disadvantages of the Hyundai D4HC engine
- This diesel engine does not tolerate low-quality fuel, it quickly wears out the high-pressure fuel pump;
- In the event of a breakdown, the pump immediately begins to drive chips and spreads it through the fuel system;
- The turbine here serves for a long time, but quite often the stem of changing its geometry wedges;
- Glow plugs and crankshaft damper pulley have a modest resource here;
- The classic problems of diesel engines with a particulate filter and an EGR valve are also here.
