Disadvantages of the Hyundai G4CS engine
- The most famous engine problem is the low resource of timing belts and balancers.
- Due to the vibration of the balancer shafts, the supports of the power unit are quickly destroyed.
- The use of low-quality oils greatly affects the resource of hydraulic lifters.
- At high mileage, the exhaust manifold bursts, but usually it can be welded.
- Floating speeds are also common due to contamination of the throttle or idle speed controller.
