Brake pad wear
Over time, brake pads wear down and need to be replaced to maintain effective braking.
Brake rotor warping
Excessive heat from braking can cause the brake rotors to warp, leading to vibrations and reduced braking efficiency.
Afm (active fuel management) issues
The AFM system can sometimes cause lifter failure or excessive oil consumption, leading to engine performance issues.
Timing chain wear
The timing chain in the L83 engine may wear out over time, causing engine misfires or timing issues.
Oil consumption
Some L83 engines are known for higher-than-normal oil consumption, which can lead to low oil levels and engine damage if not monitored.
Carbon build-up
Direct injection engines like the L83 can suffer from carbon buildup on the intake valves, affecting performance and fuel efficiency.
