Problems:

Brake fluid leaks
Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or wheel cylinders, leading to reduced braking efficiency.
Brake fade
Overheating of brake components can cause brake fade, where braking power is temporarily lost.
Warped brake rotors
Repeated heavy braking can cause the brake rotors to warp, leading to vibrations and reduced braking performance.
Worn brake pads
Brake pads wear out over time and need regular replacement to maintain braking efficiency.
Engine overheating
V-shaped engines can have cooling issues, especially if the cooling system is not maintained properly.
Oil leaks
V-shaped engines, like the WRN L35, can develop oil leaks from the valve cover gaskets or oil pan.
Timing chain issues
The timing chain in the L35 engine may stretch or wear out over time, leading to engine performance problems.
Intake manifold gasket failure
The CPI (Central Port Injection) system can lead to intake manifold gasket failures, causing coolant leaks and engine performance issues.
Misfires
The 6-cylinder V-shaped engine may experience misfires due to faulty spark plugs, ignition coils, or fuel injectors.
Fuel pump failure
The fuel pump can fail over time, leading to engine stalling or difficulty starting.
Egr valve issues
The Exhaust Gas Recirculation (EGR) valve can become clogged or fail, causing rough idling and poor engine performance.

Problems:

Brake fluid leaks
Hydraulic brake systems rely on brake fluid to function properly. Leaks can cause a loss of pressure, leading to reduced braking performance or complete brake failure.
Brake pad wear
Over time, brake pads wear down and need to be replaced. Worn brake pads can reduce braking efficiency and cause damage to the brake rotors.
Air in brake lines
Air can get trapped in the hydraulic brake lines, causing a spongy brake pedal and reducing braking effectiveness. This usually requires bleeding the brake system to remove the air.
Master cylinder failure
The master cylinder is responsible for generating the hydraulic pressure needed for braking. A failing master cylinder can lead to inconsistent braking or a complete loss of braking ability.
Engine overheating
V-shaped engines can sometimes experience cooling issues, especially if the coolant system is not maintained properly. Overheating can cause significant engine damage if not addressed promptly.
Misfiring cylinders
V-shaped engines with six cylinders like the WRN L35 can experience misfires due to issues with spark plugs, ignition coils, or fuel injectors. This can lead to poor engine performance and reduced fuel efficiency.
Intake manifold gasket leaks
The intake manifold gasket in V-shaped engines can fail, leading to coolant or air leaks. This can cause engine overheating, poor fuel economy, and rough idling.
Timing chain wear
The WRN L35 engine might use a timing chain, which can stretch or wear out over time. This can lead to timing issues, causing poor engine performance and potentially severe engine damage if the chain breaks.
Fuel injector problems
Engines with Central Port Injection (CPI) like the WRN L35 can experience problems with fuel injectors, leading to rough idling, poor acceleration, and increased emissions.
Coolant leaks
V-shaped engines have more complex coolant routing, which increases the potential for leaks in hoses, the radiator, or the water pump. Coolant leaks can lead to overheating and engine damage.
Crankshaft position sensor failure
The crankshaft position sensor is crucial for engine timing. If it fails, it can cause the engine to stall, misfire, or not start at all.
