Some users have reported excessive oil consumption in GM's L83 engines, which might require more frequent oil top-ups or checks.

The Active Fuel Management (AFM) system can sometimes lead to lifter failure, causing engine noise and performance issues.

Direct injection engines like the L83 can experience carbon buildup on intake valves, which may affect performance and fuel efficiency over time.

Premature wear of the timing chain may occur, leading to noise and potential engine damage if not addressed.

Problems with fuel injectors can lead to misfires or reduced engine performance, requiring cleaning or replacement.

Some owners have reported coolant leaks from hoses or the radiator, which can lead to overheating if not fixed.

Although not directly related to the engine, some GMC Yukon models have experienced transmission shudder, which might feel like engine problems.

Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or calipers.

Overheating of the brake system can cause a loss of braking power.

Excessive heat or hard braking can cause the brake rotors to warp, leading to vibration when braking.

The L92 V8 engine can experience misfires due to faulty spark plugs, ignition coils, or fuel injectors.

The Active Fuel Management system in the L92 engine can develop problems, leading to rough idling or loss of power.

The L92 V8 engine is known to have higher oil consumption, potentially due to piston ring issues.

The L92 engine's timing chain can stretch over time, leading to poor engine performance or timing issues.

Radiator or hose leaks are common and can lead to engine overheating.

Carbon buildup in the throttle body can cause poor throttle response or stalling.

The 2007 GMC Yukon can experience transmission issues, such as hard shifting or slipping gears.

The fuel pump can fail, leading to engine stalling or failure to start.

Faulty oxygen sensors can cause poor fuel economy and increased emissions.

The air conditioning system can develop leaks or compressor failures, leading to ineffective cooling.

Components like the ball joints, control arms, and bushings can wear out, leading to poor handling or noise.

Hydraulic brake systems can develop leaks in the brake lines, which can lead to reduced braking efficiency or brake failure.

If air gets into the hydraulic brake lines, the brake pedal may feel spongy and less responsive.

Over time, brake rotors can warp due to excessive heat, leading to vibrations when braking.

Brake pads naturally wear out over time and need to be replaced to maintain proper braking performance.

The V-shaped GM L59 engine can experience misfires due to issues with spark plugs, ignition coils, or fuel injectors.

The V8 engine may consume oil over time, which can lead to low oil levels and potential engine damage if not monitored.

The iron block engine may develop coolant leaks, which can cause overheating and engine damage.

The gaskets can fail and lead to coolant or air leaks, affecting engine performance.

The fuel pump may wear out, leading to fuel delivery problems and engine stalling or failure to start.

This sensor can fail, causing erratic engine behavior and poor acceleration.

Over time, carbon deposits can build up in the engine, affecting performance and fuel efficiency.

Leaks in the hydraulic brake system can cause a decrease in braking efficiency.

Air in the hydraulic brake lines can cause the brake pedal to feel soft or spongy.

Regular wear and tear can lead to decreased braking performance.

The GM L83 engine is known for higher oil consumption, which can lead to low oil levels.

The Active Fuel Management (AFM) system can cause lifter failures, leading to engine noise and performance issues.

The SIDI (Spark Ignition Direct Injection) system can have issues with clogged or failing fuel injectors.

The Variable Valve Timing (VVT) system can have issues with timing chain wear or tensioner failure.

The fuel pump can fail, especially when using E85, leading to starting issues or engine stalling.

Overheating can cause the aluminum engine block to warp, leading to head gasket failures.

The 2016 GMC Yukon is known for problems with the automatic transmission, including rough shifting and transmission fluid leaks.
