Most common problems:

Brake fluid leaks

Hydraulic brake systems can suffer from leaks in the brake lines, master cylinder, or wheel cylinders, leading to reduced braking efficiency.

Brake fade

Overheating of the brake components due to heavy use can reduce braking performance.

Abs sensor failure

The Anti-lock Braking System (ABS) sensors can malfunction, affecting the vehicle's ability to prevent wheel lockup.

Master cylinder failure

The master cylinder can wear out over time, causing a spongy brake pedal or brake fluid leaks.

Brake pad wear

Brake pads can wear down, leading to reduced braking power and the need for replacement.

Cracked brake hoses

Brake hoses can crack and leak brake fluid, reducing braking efficiency.

Engine misfire

The V6 configuration can experience misfires due to faulty spark plugs, ignition coils, or fuel injectors.

Intake manifold gasket failure

The intake manifold gasket can fail, causing coolant or air leaks and affecting engine performance.

Timing chain issues

The timing chain can stretch or wear out, leading to timing issues and potentially severe engine damage.

Oil leaks

The V6 engine can develop oil leaks from the valve covers, oil pan, or rear main seal.

Fuel injector problems

The Central Port Injection (CPI) system can have issues with clogged or malfunctioning fuel injectors, leading to poor engine performance.

Coolant leaks

The engine can develop coolant leaks from the water pump, radiator, or hoses, leading to overheating.

Egr valve failure

The Exhaust Gas Recirculation (EGR) valve can become clogged or fail, affecting engine emissions and performance.

Crankshaft position sensor failure

The crankshaft position sensor can fail, causing the engine to stall or not start.

Vacuum leaks

Vacuum leaks can occur in the intake manifold or vacuum lines, leading to rough idle and poor engine performance.
