Problems:

Brake fluid leaks

Hydraulic brake systems rely on brake fluid to function. Leaks can lead to reduced braking performance or failure.

Worn brake pads or rotors

Over time, brake pads and rotors wear down and may need to be replaced to ensure effective braking.

Brake line corrosion

Hydraulic brake systems can suffer from corroded brake lines, especially in areas with harsh winters and road salt.

Abs sensor failure

Standard Dynamic Brake Support (DBS) systems often rely on ABS sensors which can fail and lead to improper brake modulation.

Engine misfires

GM L96 engines can experience misfires due to issues with spark plugs, ignition coils, or fuel injectors.

Oil consumption

The 8-cylinder L96 engine may exhibit higher oil consumption, which can lead to engine wear if not monitored and managed.

Transmission issues

The GMC Sierra 2017 can have transmission problems such as slipping gears or hard shifts, which can be related to the engine's performance.

Fuel system problems

E85-compatible engines like the L96 can encounter issues with fuel injectors or fuel pumps, especially if the ethanol content fluctuates.

Cooling system failures

The engine may suffer from overheating due to coolant leaks, a failing water pump, or radiator issues.

Timing chain wear

Over time, the timing chain in the L96 engine may stretch or wear out, leading to potential engine timing issues.

GMC Sierra 2017

The 2017 GMC Sierra Denali is a robust and feature-packed truck. It boasts a 5.3-liter L83 engine with advanced technologies like Variable Valve Timing and Direct Injection. Safety is a priority with standard features such as Dynamic Brake Support, Lane Departure Warning, and Forward Collision Warning. Luxurious touches include a backup camera, keyless ignition, and a spacious cabin with seating for five.

Problems:

Brake fluid leaks

Hydraulic brake systems can suffer from leaks in the brake lines, calipers, or master cylinder, which can lead to reduced braking efficiency.

Brake fade

This occurs due to overheating of the brake components, which can happen under heavy braking conditions. It results in a temporary loss of braking power.

Worn brake pads

Over time, brake pads wear down and need to be replaced. If not addressed, it can lead to damage to the brake rotors.

Brake pedal sponginess

Air or moisture in the hydraulic brake lines can cause the brake pedal to feel spongy or less responsive.

Abs malfunction

Standard Dynamic Brake Support (DBS) systems can sometimes experience issues with the Anti-lock Braking System (ABS), often indicated by the ABS warning light on the dashboard.

Sticking calipers

Calipers can sometimes get stuck due to rust or debris, leading to uneven braking and increased wear on the brake pads and rotors.

Warped brake rotors

Excessive heat can cause brake rotors to warp, leading to vibrations or pulsations when braking.

Hydraulic system failure

Although rare, a complete failure of the hydraulic brake system can occur due to severe leaks or a failed master cylinder, leading to a total loss of braking capability.
