Problems:
Brake fluid leaks
Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or calipers, leading to reduced braking performance.
Warped brake rotors
Heavy use or overheating can cause brake rotors to warp, leading to vibration or pulsation during braking.
Brake pad wear
Brake pads wear down over time and need regular inspection and replacement to maintain braking efficiency.
Abs system failure
The Anti-lock Braking System (ABS) may malfunction, causing the ABS warning light to illuminate and affecting braking performance.
Vacuum pump failure
A failure in the vacuum pump can lead to reduced brake assistance, making it harder to press the brake pedal.
Oil consumption
The L87 engine may experience higher-than-normal oil consumption, requiring more frequent oil top-offs and monitoring.
Valve lifter failure
Some models with the L87 engine have reported issues with valve lifter failure, leading to engine noise and potential performance loss.
Carbon buildup
Direct Injection (DI) engines like the L87 can experience carbon buildup on intake valves, affecting engine performance and fuel economy.
Cooling system issues
V-shaped engines can have cooling inefficiencies, leading to potential overheating problems if not properly maintained.
Timing chain wear
Over time, the timing chain in the L87 engine can wear out, leading to noise and potential engine timing issues.
