Problems:

Brake fluid leaks
In hydraulic brake systems, leaks can occur, leading to reduced braking efficiency and potential brake failure.
Brake pedal sponginess
Air in the hydraulic lines can cause the brake pedal to feel spongy, reducing braking performance.
Brake rotor wear
Over time, brake rotors can wear unevenly or become warped, leading to vibrations or reduced braking effectiveness.
Carbon buildup
Direct Injection engines like the L87 can experience carbon buildup on intake valves, affecting engine performance and fuel efficiency.
Oil consumption
V-shaped engines, including the L87, can sometimes consume more oil than expected, leading to low oil levels and potential engine damage if not monitored.
Cylinder deactivation issues
The L87 engine features Dynamic Fuel Management (DFM), which can sometimes cause rough running or vibrations when switching between cylinder modes.
Cooling system problems
Aluminum engines, such as the L87, can be sensitive to cooling system issues, leading to overheating or coolant leaks.
Timing chain wear
Over time, the timing chain in V8 engines can stretch or wear, causing timing issues and potential engine damage.
