Disadvantages of the Hyundai G4LH engine
This engine, like all direct injection engines, has carbon deposits on the intake valves; on specialized forums, their complaints are limited to loud operation or excessive vibration;
On a run of less than 100,000 kilometers, the network details isolated instances of timing chain replacement;
The adsorber valve and short-lived engine mounts are the unit’s weak points.
