Problems:
Engine oil consumption

Afm lifter failure
The Active Fuel Management (AFM) system can sometimes lead to lifter failure, causing engine noise and performance issues.
Carbon buildup
Direct injection engines like the L83 can experience carbon buildup on intake valves, which may affect performance and fuel efficiency over time.
Timing chain wear
Premature wear of the timing chain may occur, leading to noise and potential engine damage if not addressed.
Fuel injector issues
Problems with fuel injectors can lead to misfires or reduced engine performance, requiring cleaning or replacement.
Coolant leaks
Some owners have reported coolant leaks from hoses or the radiator, which can lead to overheating if not fixed.
Transmission shudder
Although not directly related to the engine, some GMC Yukon models have experienced transmission shudder, which might feel like engine problems.
