MOST COMMON PROBLEMS

GMC Sierra 2014

The 2014 GMC Sierra 1500 Denali is a robust 4WD pickup equipped with a 6.2L V8 engine, offering up to 378 horsepower. Manufactured by General Motors in Silao, Mexico, this crew cab truck ensures safety with airbags in all rows and features such as a stoichiometric gasoline direct injection system. It's designed for heavy-duty tasks with a gross vehicle weight rating between 7,001 - 8,000 lbs. The Sierra Denali also supports both gasoline and ethanol (E85) fuel types.

Spec:

Brake System Type
Hydraulic
Engine Model
L86 - VVT, AFM, E85 Max, Aluminum.
Engine Number of Cylinders
8

Problems:

Brake fluid leak
Hydraulic brake systems can develop leaks, leading to reduced braking performance and potential brake failure.
Brake fade
Overheating of the brake components can cause a temporary loss of braking power, known as brake fade.
Warped brake rotors
Excessive heat or improper torque can cause the brake rotors to warp, leading to vibrations when braking.
Faulty brake master cylinder
The master cylinder can wear out over time, causing a spongy brake pedal or brake failure.
Throttle body issues
Carbon buildup or electronic malfunctions in the throttle body can lead to poor engine performance.
Active fuel management (afm) problems
The AFM system, which deactivates certain cylinders to save fuel, can malfunction, causing rough engine performance or misfires.
Timing chain wear
The timing chain can stretch or wear out over time, leading to timing issues and potential engine damage.
Fuel injector problems
E85 fuel can cause injector clogging or failure over time, affecting engine performance.
Cooling system leaks
Aluminum engines can develop leaks in the cooling system, leading to overheating.
Oil consumption
The L86 engine is known to consume oil, which may require frequent top-offs and monitoring.
Transmission shifting issues
Problems with the transmission control module or hydraulic systems can lead to erratic or harsh shifting.
CHEVROLET Silverado 2014

The 2014 Chevrolet Silverado 1500 LTZ is a robust crew cab pickup powered by a 6.2L V8 engine, delivering strong performance with its 4WD system. Manufactured by General Motors in Silao, Mexico, this truck features comprehensive safety measures, including curtain airbags in all rows and side airbags in the first row. With a hydraulic brake system and a gross vehicle weight rating of Class 2F, it’s built for both utility and comfort.

Spec:

Brake System Type
Hydraulic
Engine Model
L86 - VVT, AFM, E85 Max, Aluminum.
Engine Number of Cylinders
8

Problems:

Brake fluid leaks
Hydraulic brake systems can develop leaks in brake lines, hoses, or seals, leading to reduced braking efficiency or failure.
Brake fade
Overheating of brake components, particularly during heavy use, can cause a temporary loss of braking power.
Abs malfunction
The Anti-lock Braking System (ABS) may encounter sensor failures or electronic control unit issues, resulting in erratic braking behavior.
Brake pad wear
Regular use leads to wear and tear on brake pads, requiring periodic replacement to maintain effective braking.
Engine misfire
The L86 engine may experience misfires due to issues with ignition coils, spark plugs, or fuel injectors.
Active fuel management (afm) issues
AFM can cause lifter noise, lifter failure, or oil consumption problems in the L86 engine.
Oil consumption
Some L86 engines are known to consume more oil than usual, which may require more frequent oil checks and changes.
Timing chain wear
Over time, the timing chain can stretch or wear out, leading to potential engine timing issues and performance problems.
Fuel system problems
Issues with the fuel pump, injectors, or fuel lines can cause a decrease in engine performance and efficiency.
Cooling system failures
Problems with the radiator, water pump, or thermostat can lead to overheating, which can severely damage the engine.
E85 fuel compatibility issues
While the engine is designed to run on E85, improper fueling or fuel quality can lead to performance and maintenance issues.
Vvt (variable valve timing) problems
Malfunctions in the VVT system can affect engine performance, fuel economy, and emissions.
