Most common problems:

Brake fluid leak

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

Brake pad wear

Over time, brake pads wear down and need to be replaced to maintain effective braking.

Brake rotor warping

Excessive heat from braking can cause the brake rotors to warp, leading to vibrations and reduced braking efficiency.

Afm (active fuel management) issues

The AFM system can sometimes cause lifter failure or excessive oil consumption, leading to engine performance issues.

Timing chain wear

The timing chain in the L83 engine may wear out over time, causing engine misfires or timing issues.

Oil consumption

Some L83 engines are known for higher-than-normal oil consumption, which can lead to low oil levels and engine damage if not monitored.

Carbon build-up

Direct injection engines like the L83 can suffer from carbon buildup on the intake valves, affecting performance and fuel efficiency.

Transmission problems

The 2014 GMC Sierra is known to have issues with its automatic transmission, including hard shifts and slipping.

Electrical issues

Problems with the electrical system, such as faulty sensors or wiring issues, can cause various engine and vehicle performance problems.

Fuel injector problems

Faulty or clogged fuel injectors can lead to poor engine performance, misfires, and reduced fuel efficiency.
