Hydraulic brake systems rely on brake fluid to function properly. Leaks can lead to reduced braking efficiency or complete brake failure.

Continuous use of brakes, especially in heavy or high-speed applications, can cause the brakes to overheat and lose effectiveness.

The master cylinder is crucial in a hydraulic brake system. Failure can result in a loss of braking power or inconsistent braking.

The Anti-lock Braking System (ABS) sensors can malfunction, causing the ABS to not work properly, which can affect vehicle control during braking.

Excessive heat or aggressive braking can cause brake rotors to warp, leading to vibrations and reduced braking efficiency.

Air pockets in the hydraulic brake lines can cause spongy brakes and reduce braking performance.

Corrosion in brake lines can lead to leaks and reduced hydraulic pressure in the brake system, affecting braking power.

Sticking brake calipers can cause uneven brake pad wear and reduced braking efficiency on one side of the vehicle.

As an optional feature, if the DBS malfunctions, it can result in inconsistent braking support during emergency stops.

Engine braking can be less effective if there are problems with the engine configuration or if the engine is not performing optimally.

Warped rotors or issues with the brake pads can cause vibrations or pulsations when braking.

Malfunctions in the brake system can trigger warning lights on the dashboard, indicating an issue that needs to be addressed.

The brake booster assists in applying the necessary force to the brakes. Failure can result in a hard brake pedal and reduced braking power.

Using non-FCA approved parts can lead to compatibility issues and reduced performance in the brake system.

The DBS system might fail to activate during emergency braking situations, potentially increasing stopping distances.

Given the high power output (395 hp), the engine may be prone to overheating if the cooling system is inadequate or if there are issues with the radiator or coolant levels.

In-Line 6-cylinder engines, especially high-performance ones like the AJ20P6, can experience turbocharger failures, leading to reduced power and efficiency.

The AJ20P6 engine might develop oil leaks over time, particularly around the valve cover gasket or oil pan, which can lead to engine damage if not addressed.

In-Line 6-cylinder engines can suffer from timing chain issues, such as stretching or failure, which can result in engine misfires or complete failure.

High-performance engines often face fuel injector or fuel pump issues, which can lead to poor engine performance or stalling.

Modern engines rely heavily on ECUs, and any failure in this component can lead to various engine management issues, including poor performance and increased emissions.

Over time, the exhaust system components, including the catalytic converter and muffler, can corrode, leading to increased emissions and noise.

Sensors such as the oxygen sensor, mass airflow sensor, or knock sensor can fail, leading to incorrect fuel-air mixtures and reduced engine performance.

Although not a direct engine problem, the high power output of the AJ20P6 engine can stress the transmission, leading to potential failures or issues with shifting.

An engine misfire can occur due to issues with the ignition system, fuel system, or engine compression, leading to poor engine performance.

Turbocharger problems can result in a loss of power and efficiency, often caused by oil contamination, wear and tear, or foreign objects damaging the turbine.

Oil leaks can stem from various points in the engine, such as gaskets, seals, or oil pan, leading to oil loss and potential engine damage.

Overheating issues can arise from coolant leaks, a faulty thermostat, a failing water pump, or a clogged radiator, potentially causing severe engine damage.

A worn or broken timing chain/belt can lead to improper engine timing, causing poor performance or even engine damage.

Faulty fuel injectors can result in poor fuel delivery, leading to reduced engine performance, increased emissions, and potential engine damage.

Malfunctioning sensors, such as the oxygen sensor or mass airflow sensor, can cause incorrect air-fuel mixture, leading to poor engine performance and increased emissions.

For diesel engines, the DPF can become clogged, causing increased exhaust backpressure, reduced performance, and potential engine damage.

A malfunctioning EGR valve can cause poor engine performance, increased emissions, and potential engine damage due to improper exhaust gas recirculation.
