Disadvantages of the Hyundai G6DV engine
Only individual electrical component failures are discussed on specialized forums.
Keep an eye on cooling because all of the aluminum V6s in this series are afraid of overheating.
Although there haven’t been any complaints about oil consumption thus far, this line’s engines are generally prone to it.
It is not necessary to adjust the valve clearance because hydraulic compensators are available here.
