Disadvantages, breakdowns and problems of the Hyundai G4CM
A strong clatter under the hood is a sign of failure of the hydraulic lifters
Vibration of the power unit indicates critical wear of one of the engine bearings
Floating engine speeds are often caused by contamination of the injectors, throttle and IAC
However, these are all trifles, the main thing here is to monitor the condition of the belts: timing and balancers
After all, the breakage of any of them almost always turns into a meeting of pistons with valves
