Problems:

Brake fluid leaks
Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or calipers, leading to reduced braking performance.
Abs malfunction
The Anti-lock Braking System (ABS) sensors or module may fail, causing the ABS light to illuminate and potentially affecting braking efficiency.
Oil consumption
The GM LQ4 engine is known to consume oil, which may require frequent oil checks and top-ups.
Intake manifold gasket failure
The V-shaped configuration can lead to issues with the intake manifold gaskets, resulting in vacuum leaks and poor engine performance.
Cooling system issues
The iron block of the LQ4 engine can contribute to overheating issues if the cooling system is not properly maintained.
Fuel pump failure
The fuel pump in older Chevrolet Suburban models can fail, leading to stalling or difficulty starting the engine.
Transmission problems
The 2004 Chevrolet Suburban is prone to transmission issues, such as slipping or hard shifting, especially if not regularly serviced.
Rust and corrosion

Problems:

Brake fluid leaks
Hydraulic brake systems rely on fluid to transfer force from the brake pedal to the brake pads; leaks can reduce braking efficiency.
Brake master cylinder failure
The master cylinder can wear out over time, leading to a loss of hydraulic pressure and ineffective braking.
Brake booster issues
The brake booster can fail, making it harder to press the brake pedal and reducing braking performance.
Abs module malfunction
The Anti-lock Braking System (ABS) module can fail, leading to compromised brake control during emergency stops.
Brake pad and rotor wear
Over time, brake pads and rotors wear out and need replacement to maintain effective braking.
Engine misfire
The LQ4 engine can experience misfires due to faulty spark plugs, ignition coils, or fuel injectors.
Oil consumption
Some LQ4 engines are known for higher-than-normal oil consumption, which can lead to engine damage if not monitored.
Intake manifold gasket leaks
The intake manifold gasket can fail, causing coolant or air leaks that affect engine performance.
Throttle body issues
The electronic throttle body can fail, leading to poor throttle response or idle issues.
Cooling system problems
Radiator, water pump, or thermostat failures can lead to engine overheating.
Transmission problems
The 2005 Chevrolet Suburban can experience transmission issues like slipping, hard shifts, or failure, especially as the vehicle ages.
Fuel pump failure
The fuel pump can fail, leading to poor engine performance or a no-start condition.
Electrical issues
The vehicle can suffer from various electrical problems, including faulty sensors, wiring issues, and failing alternators.
