Most common problems:

Brake fluid leaks

Hydraulic brake systems can develop leaks in the brake lines, hoses, or master cylinder, leading to a loss of braking power.

Brake pedal feels spongy

Air trapped in the hydraulic brake lines can cause the brake pedal to feel soft or spongy, affecting braking performance.

Brake pads wear out quickly

High-performance or heavy vehicles like the CHEVROLET GMT-400 can cause brake pads to wear out faster, requiring frequent replacements.

Overheating engine

V-shaped engines, particularly high-output models like the ROM L65, can be prone to overheating, especially under heavy load or in hot climates.

Misfiring cylinders

The V8 configuration can sometimes lead to misfiring in one or more cylinders, which can be caused by issues such as faulty spark plugs, ignition coils, or fuel injectors.

Oil leaks

V-shaped engines often have complex oil pathways and seals, which can develop leaks over time, leading to reduced engine performance and potential damage.

Engine knocking

High-output engines like the ROM L65 may experience knocking or pinging noises, often due to using low-octane fuel or issues with the timing.

Cooling system issues

The compact design of V-shaped engines can lead to hotspots and cooling inefficiencies, potentially causing coolant leaks or overheating.

Transmission problems

The powerful engine of the CHEVROLET GMT-400 can put a strain on the transmission, leading to issues such as slipping gears, hard shifts, or transmission fluid leaks.

Exhaust manifold cracks

V8 engines generate a lot of heat, which can cause the exhaust manifold to crack over time, leading to exhaust leaks and increased emissions.
