Most common problems:

Brake fluid leaks

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

Spongy brake pedal

Air can enter the hydraulic system, causing a spongy or soft brake pedal feel, which reduces braking performance.

Brake fade

Overheating of the brake components, especially during heavy use, can cause brake fade, leading to reduced braking effectiveness.

Cylinder deactivation issues

The Active Fuel Management (AFM) system in the L92 engine can sometimes fail, causing misfires or rough running.

Oil consumption

The V8 L92 engine is known to consume oil, which can lead to low oil levels and potential engine damage if not monitored.

Timing chain wear

The L92 engine can experience timing chain stretch or wear, which can cause timing issues and engine performance problems.

Throttle body issues

Throttle body failures or carbon buildup can cause poor throttle response or stalling.

Cooling system problems

Radiator, water pump, or thermostat failures can lead to overheating, especially in older models.

Transmission issues

The transmission in the 2008 GMC Sierra can have problems with slipping, hard shifts, or failure, particularly if not properly maintained.

Fuel injector problems

Clogged or faulty fuel injectors can cause engine misfires, poor fuel economy, and reduced performance.

Electrical system failures

Issues with the vehicle's electrical system, such as faulty sensors or wiring problems, can lead to various engine performance and drivability issues.

Exhaust manifold leaks

The exhaust manifolds on the L92 engine can crack or develop leaks, leading to exhaust noise and potential performance loss.
