Disadvantages of the Hyundai G3LE engine
Thus far, the majority of complaints have been about electrical issues or the Start-Stop system.
It has carbon buildup on the intake valves, just like all direct injection units.
The timing chain, which frequently spans 100,000 kilometers, lacks substantial resources.
Monitoring the cooling system is also crucial because this motor is terrified of overheating.
