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.
