Oil leaks can occur from various engine components, such as the valve cover gasket, oil pan gasket, or seals. This can lead to reduced engine performance and potential damage if not addressed promptly.

Overheating can be caused by issues such as a faulty thermostat, a leaking radiator, or a malfunctioning water pump. This can lead to significant engine damage if not resolved.

Engine misfires can result from faulty spark plugs, ignition coils, or fuel injectors. This causes the engine to run inefficiently and can lead to further mechanical issues.

If the Mustang is equipped with a turbocharger, common issues include turbo lag, excessive oil consumption, and turbo failure. These problems can reduce engine performance and efficiency.

A worn or broken timing belt/chain can cause serious engine damage. Symptoms include ticking noises from the engine, engine misfires, and difficulty starting the vehicle.

Issues with the fuel pump, fuel filter, or fuel injectors can lead to poor fuel delivery, causing the engine to perform poorly or even stall.

Modern engines rely on various sensors (e.g., oxygen sensor, mass airflow sensor) to manage performance. Failure of these sensors can lead to poor engine performance and increased emissions.

Problems with the exhaust system, such as a clogged catalytic converter or a leaking exhaust manifold, can lead to reduced engine efficiency and increased emissions.

Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or wheel cylinders, leading to decreased brake performance.

Over time, brake pads wear down and need replacement to ensure effective braking.

Brake rotors can become warped or excessively worn, causing vibrations or reduced braking efficiency.

The master cylinder can fail, leading to a loss of hydraulic pressure and brake function.

Air bubbles in hydraulic brake lines can cause a spongy brake pedal and reduced braking efficiency.

In rear drum brake systems, wheel cylinders can leak or fail, reducing braking performance.

If equipped, the Anti-lock Braking System (ABS) can experience sensor or module failures, leading to a loss of ABS functionality.

Common in the 2015 Ford Mustang with an in-line 4-cylinder engine due to worn gaskets or seals.

The timing belt may wear out or fail, leading to potential engine damage if not replaced at recommended intervals.

Turbocharger failure or malfunction can occur, especially if maintenance on the turbo system is neglected.

This can be caused by a variety of issues including coolant leaks, thermostat failure, or a malfunctioning radiator.

Can be due to ignition coil failure, spark plug issues, or fuel injector problems.

The fuel pump may fail, leading to issues with fuel delivery to the engine.

Direct injection engines like the 4V can experience carbon build-up on intake valves, leading to reduced performance.

Engine mounts can wear out over time, causing vibrations and noise.

Direct injection engines like the 4V can experience carbon build-up on intake valves, leading to reduced performance.

Engine mounts can wear out over time, causing vibrations and noise.

Dynamic Brake Support (DBS) systems can sometimes fail to engage properly, leading to a lack of additional braking force during emergency stops.

Misfires can occur due to issues with fuel delivery, ignition, or engine management systems, especially in high-performance engines like those in the Mustang.

If equipped with a turbocharger, issues such as boost leaks, turbo lag, or turbo failure can arise, impacting performance.

High-performance engines are prone to overheating if the cooling system isn't maintained properly, which can lead to engine damage.

Modern engines rely on numerous sensors; any sensor malfunction can trigger check engine lights and affect performance.

Over time, the timing chain or belt can wear out, leading to poor engine performance or even catastrophic engine failure if not replaced in time.

Dirty or clogged fuel injectors can cause poor engine performance, reduced fuel efficiency, and increased emissions.

Problems with the exhaust system, such as leaks or catalytic converter failure, can affect engine performance and emissions.
