Problems:

Oil leaks
Common in V-shaped engines due to the complexity of the design and multiple gaskets and seals that can fail.
Timing chain issues
V8 engines, such as the M278, can experience timing chain stretch or failure, leading to misfires and other performance issues.
Turbocharger problems
The M278 engine is equipped with a turbocharger, which can fail due to oil starvation, leading to reduced power and efficiency.
Spark plug and ignition coil failures
With eight cylinders, more components are prone to wear and tear, leading to misfires and rough idling.
Carbon build-up
Direct Fuel Injection (DFI) engines are prone to carbon build-up on the intake valves, which can affect performance and fuel economy.
Cooling system failures
V8 engines generate a lot of heat, and any failure in the cooling system can lead to overheating and potential engine damage.
Fuel injector issues
The complex fuel injection system in modern engines can fail, causing poor fuel economy or engine misfires.
Crankshaft position sensor failure
A common issue in many engines that can cause stalling or difficulty starting the engine.

Problems:

Oil leaks
V-shaped engines, such as the M276, can develop oil leaks at the valve cover gaskets, timing cover, and oil pan. These leaks can lead to oil loss and potential engine damage if not addressed.
Timing chain issues
The M276 engine may experience timing chain wear or failure, which can cause poor engine performance, noise, and potentially severe engine damage if the chain breaks.
Carbon build-up
Direct Fuel Injection (DFI) engines like the M276 can suffer from carbon build-up on intake valves, leading to reduced performance, misfires, and poor fuel economy.
Coolant leaks
The M276 engine may develop coolant leaks from the water pump or thermostat housing, leading to overheating and potential engine damage if not repaired.
Misfires
Faulty ignition coils or spark plugs can cause misfires in the M276 engine, leading to rough running, poor performance, and increased emissions.
Turbocharger problems
If the GLS-Class is equipped with a turbocharged version of the M276, issues such as turbocharger failure or boost leaks can arise, leading to reduced power and performance.
