Problems:

Brake fluid leaks
Hydraulic brake systems can develop leaks in brake lines, hoses, or master cylinder seals, leading to reduced braking efficiency and potential brake failure.
Worn brake pads
Over time, brake pads wear down and need to be replaced to maintain effective braking performance.
Brake rotor issues
Brake rotors can become warped or worn, leading to vibrations or reduced braking effectiveness.
Brake pedal issues
A spongy or soft brake pedal can indicate air in the brake lines or issues with the master cylinder.
Overheating issues
V-shaped engines with 6 cylinders can sometimes suffer from overheating problems due to cooling system inefficiencies or leaks.
Misfiring cylinders
The MPI (Multi-Point Injection) system can sometimes experience issues with fuel injectors, leading to misfiring cylinders.
Timing belt failure
The 2003 Mitsubishi Montero's V6 engine relies on a timing belt that can wear out and potentially fail, causing engine damage.
Oil leaks
Common in older vehicles, oil leaks can occur from gaskets, seals, or the oil pan.
Spark plug wear
Spark plugs can wear out over time, leading to reduced engine performance and fuel efficiency.
Intake manifold gasket failure
Can lead to coolant leaks and engine overheating.
Fuel pump issues
The fuel pump can wear out or fail, leading to starting issues or engine stalling.
Battery and electrical problems
