Without Dynamic Brake Support, the vehicle may have reduced braking assistance in emergency situations, potentially increasing stopping distances.

High engine brake horsepower can lead to greater wear and tear on engine components, and it may require more frequent maintenance to ensure the engine runs smoothly.

V-shaped engines can be more complex and expensive to repair due to the arrangement of the cylinders and the additional components required for balance and performance.

Direct fuel injection systems can be prone to issues such as carbon buildup on intake valves, which can lead to reduced performance and increased maintenance costs.

Turbocharged engines are subject to additional stress and heat, which can lead to problems such as turbo failure, oil leaks, and increased maintenance needs.

High-performance engines like the M177 can have more stringent maintenance requirements and may be more costly to repair due to specialized parts and technologies.

Engines with more cylinders generally consume more fuel and can be more expensive to maintain and repair due to the increased number of components.

While reliable, four-stroke engines require regular maintenance, such as oil changes and valve adjustments, to keep them running efficiently.

Mercedes-Benz vehicles, including the C-Class, can sometimes experience issues specific to the brand, such as electrical problems, transmission issues, and higher repair costs due to the luxury components used.

Newer models, like the 2020 Mercedes-Benz C-Class, may have issues related to recent technology and design updates. These can include software bugs, recalls, and teething problems as new features and components are integrated.

The M177 engine used in the 2021 Mercedes-Benz C-Class can be prone to oil leaks, often from the valve cover gaskets or the oil pan gasket.

This engine features a turbocharger which can occasionally suffer from problems such as turbo lag, reduced performance, or failure due to wear and tear.

The direct fuel injection system can lead to carbon buildup on the intake valves, which can affect engine performance and fuel efficiency.

Over time, the timing chain can stretch or wear out, which can lead to poor engine performance or even engine damage if not addressed.

The cooling system in the M177 engine can sometimes develop leaks or fail to maintain proper engine temperature, leading to overheating issues.

Various engine sensors, such as the oxygen sensor or mass airflow sensor, may fail over time and affect engine performance and emissions.

Direct fuel injectors can become clogged or fail, leading to poor engine performance, misfires, or reduced fuel efficiency.

DBS may not engage properly, leading to reduced braking efficiency.

Could be due to faulty spark plugs, ignition coils, or fuel injectors.

Common in V-shaped engines, often from valve covers or oil pan gaskets.

Turbocharger (TC) can fail, causing loss of power and increased emissions.

Injectors can clog, affecting fuel delivery and engine performance.

Could result in overheating, especially in high-performance engines like the M177.
