Problems:
Brake fluid leaks
Hydraulic brake systems rely on brake fluid to function. A common issue is leaks in the brake lines, seals, or master cylinder, causing a loss of pressure and reduced braking efficiency.
Worn brake pads
Over time, brake pads wear down and need to be replaced. Worn pads can lead to reduced braking performance and, if ignored, can damage the brake rotors.
Brake rotor warping
Prolonged use or excessive heat can cause brake rotors to warp, leading to vibrations and reduced braking performance.
Engine misfires
The in-line 4-cylinder engine in the 2012 Chevrolet Colorado can experience misfires due to issues with spark plugs, ignition coils, or fuel injectors.
Timing chain problems
The LLV engine with Variable Valve Timing (VVT) can have issues with the timing chain stretching or failing, leading to poor engine performance or even engine damage if not addressed.
Oil consumption
Some users report higher than normal oil consumption in this engine model, which may require more frequent oil top-ups and checks.
Coolant leaks
Coolant leaks can occur from the radiator, hoses, or water pump, leading to engine overheating if not addressed promptly.
Throttle body issues
Problems with the throttle body can cause erratic idling, stalling, or reduced engine performance.
Fuel pump failure
The fuel pump may fail over time, leading to issues with fuel delivery to the engine, causing hard starts or stalling.
Oxygen sensor failure
A failing oxygen sensor can cause poor fuel economy and increased emissions, triggering the check engine light.
