Problems:

Oil leaks
The M177 engine may develop oil leaks around the valve covers, oil pan gasket, or other seals as it ages.
Timing chain issues
Over time, the timing chain can stretch or the tensioner can fail, leading to poor engine performance or even severe engine damage.
Turbocharger problems
The turbochargers in the M177 engine can suffer from oil starvation or bearing failure, leading to reduced performance or failure.
Carbon build-up
Direct Fuel Injection (DFI) engines like the M177 are prone to carbon build-up on the intake valves, which can affect engine performance and fuel efficiency.
Cooling system failures
The cooling system components, such as the water pump or radiator, can fail, leading to overheating issues.
Fuel system issues
Problems with the high-pressure fuel pumps or injectors can lead to poor engine performance, misfires, or starting issues.
Electronic throttle control issues
Problems with the electronic throttle control can cause erratic engine behavior, such as stalling or hesitation.
Crankcase ventilation issues
The crankcase ventilation system can become clogged or fail, leading to increased oil consumption and potential engine damage.
Sensor failures
Various engine sensors, such as the oxygen sensor or mass airflow sensor, can fail, affecting the engine's performance and emissions.
MERCEDES-BENZ GLS-Class 2021

Other Engine Info
L-9 / Direct Fuel Injection (DFI)

Problems:

Oil leaks
The Mercedes-Benz M176 engine is known for potential oil leaks, particularly around the valve cover gaskets and oil pan.
Timing chain issues
Some users have reported timing chain tensioner problems, which can lead to a noisy engine and potentially severe engine damage if not addressed.
Direct fuel injection problems
Direct Fuel Injection (DFI) systems can sometimes suffer from carbon buildup on intake valves, leading to reduced performance and efficiency.
Cooling system failures
The cooling system, including the water pump and radiator, may be prone to failures, particularly in hotter climates or under heavy usage.
Turbocharger issues
Turbocharger components can wear out or fail, leading to reduced engine performance and increased emissions.
Electrical problems
Modern Mercedes-Benz vehicles, including the GLS-Class, can suffer from various electrical issues, such as problems with sensors, control modules, and wiring harnesses.
Transmission problems
Although not directly related to the engine, transmission issues like rough shifting and transmission fluid leaks can affect the overall performance of the vehicle.
Fuel system issues
Problems with the fuel system, such as fuel pump failures or injector issues, can lead to poor engine performance and starting difficulties.
Engine mount failures
Engine mounts can wear out over time, leading to increased engine vibration and noise.
