Problems:
Brake fluid leaks
Hydraulic brake systems can develop leaks in the brake lines or at the master cylinder, leading to reduced braking performance.
Brake pedal feels spongy
Air in the hydraulic brake lines can cause the brake pedal to feel less firm and responsive.
Worn brake pads or rotors
Regular wear and tear can cause brake pads and rotors to degrade, leading to decreased braking efficiency and potential damage to other braking components.
Engine misfires
V-shaped engines with multiple cylinders, like the V8 in the GMC Savana, can experience misfires due to ignition or fuel delivery issues.
Fuel injector problems
Flex-fuel engines can suffer from clogged or malfunctioning fuel injectors, especially when using high-alcohol-content fuels.
Cooling system issues
High-output engines generate more heat and can experience cooling system problems, such as radiator or thermostat failures.
Oil consumption
V8 engines, particularly those with high output, can consume more oil, leading to potential low oil levels and engine wear.
Transmission issues
The power output of a high-output V8 engine can strain the transmission, leading to problems such as slipping or rough shifting.
Oxygen sensor failure
Flex-fuel engines may experience oxygen sensor failures, which can affect fuel efficiency and emissions.
Exhaust manifold cracks
V-shaped engines are prone to developing cracks in the exhaust manifold, which can cause exhaust leaks and reduce engine performance.
