Problems:

Oil leaks
Common in high-performance V-shaped engines like the M157. Seal wear and tear can cause leaks.
Coolant leaks
Possible due to the complex cooling system in the V8 engine, leading to overheating issues.
Timing chain issues
V8 engines can experience timing chain stretch or failure, causing poor engine performance.
Turbocharger problems
The M157's turbochargers may suffer from wear, leading to loss of power or turbo failure.
Excessive oil consumption
High-performance engines may consume more oil, requiring frequent top-ups.
Carbon build-up
Direct Fuel Injection (DFI) engines like the M157 are prone to carbon deposits on intake valves.
Misfiring
Can occur due to faulty spark plugs or ignition coils, common in V8 engines.
Engine mount wear
High torque and power can lead to premature engine mount wear, causing vibrations.
Fuel injector issues
Direct injection systems can suffer from clogged or faulty fuel injectors, affecting performance.
Cooling system failures
High-powered engines generate more heat, stressing the cooling system components.
Sensor failures
Modern engines like the M157 rely on many sensors that can fail, causing various issues.
Crankshaft position sensor failure
A common issue that can lead to stalling or failure to start.

Problems:

Faulty turbocharger
The M157 engine is known to experience turbocharger issues, which can lead to reduced engine performance and increased exhaust smoke.
Oil leaks
This engine model has been reported to have oil leaks, particularly from the valve cover gaskets and oil pan.
Carbon build-up
Direct injection engines like the M157 can suffer from carbon build-up on the intake valves, leading to misfires and rough idling.
Timing chain wear
Over time, the timing chain can stretch or wear out, causing rattling noises and potential engine damage if not addressed.
Cooling system problems
Issues with the water pump or radiator can lead to overheating, especially in high-performance engines like the M157.
Faulty ignition coils
Ignition coil failure can cause misfires, poor fuel economy, and reduced engine power.
Fuel injector problems
Faulty fuel injectors can lead to poor combustion, rough running, and increased emissions.
Transmission issues
Though not directly an engine problem, the transmission in the GLS-Class can sometimes experience shifting issues, which can affect overall vehicle performance.
