Most common problems:

Brake fluid leaks

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

Brake fade

Prolonged usage, especially in hilly or mountainous terrain, can lead to brake fade due to overheating of the brake components.

Warped brake rotors

Continuous heavy braking can cause the rotors to warp, resulting in vibrations or pulsations when braking.

Worn brake pads

Over time, the brake pads wear out and need to be replaced to maintain effective braking performance.

Engine misfire

The V-shaped, 6-cylinder configuration can experience misfires due to issues with spark plugs, ignition coils, or fuel injectors.

Coolant leaks

The engine's 90-degree V-configuration can sometimes lead to coolant leaks from the intake manifold gaskets.

Oil consumption

The WRN LU3 engine may consume more oil than expected, necessitating frequent checks and top-ups.

Timing chain issues

Over time, the timing chain can stretch or wear out, leading to issues with engine timing and performance.

Intake manifold gasket failure

The intake manifold gasket on this engine can fail, leading to coolant leaks and potential engine overheating.

Fuel pump failure

The fuel pump may fail, causing issues with fuel delivery to the engine and resulting in poor performance or stalling.

Transmission problems

The 2004 Chevrolet Blazer is known to have issues with the automatic transmission, including slipping gears and hard shifts.

Electrical issues

Problems with the vehicle's electrical system can lead to malfunctioning gauges, lights, and other electronic components.

Rust and corrosion

Older models like the 2004 Blazer can suffer from rust and corrosion, particularly in the brake lines and undercarriage.
