Problems:

Brake fluid leaks
Hydraulic brake systems can develop leaks in the brake lines, master cylinder, or brake calipers, leading to reduced braking efficiency.
Brake pedal goes to the floor
This can be caused by air in the brake lines, a failing master cylinder, or a significant brake fluid leak.
Overheating engine
V8 engines, especially in older models like the 2003 Jeep Grand Cherokee, can suffer from cooling system issues, such as a failing radiator, water pump, or thermostat.
Oil leaks
V8 engines are prone to oil leaks from valve cover gaskets, oil pan gaskets, or front and rear main seals.
Misfiring engine
This can be caused by faulty spark plugs, ignition coils, or fuel injectors, especially in an engine with high mileage.
Exhaust manifold leaks
V8 engines can develop cracks or leaks in the exhaust manifold, leading to a ticking noise and reduced engine performance.
Transmission issues
The 2003 Jeep Grand Cherokee is known for automatic transmission problems, including slipping gears, rough shifts, and transmission fluid leaks.
Faulty fuel pump
Fuel delivery issues can cause stalling, hard starts, or poor engine performance.
Worn suspension components
Older Jeep Grand Cherokees can have worn-out shocks, struts, and control arm bushings, leading to a rough ride and poor handling.
Electrical problems
Issues with the electrical system, such as failing sensors, wiring shorts, or faulty alternators, can cause a variety of engine and accessory problems.
Rust and corrosion
Older vehicles like the 2003 Grand Cherokee can suffer from rust and corrosion, especially in the undercarriage, brake lines, and fuel lines.

Problems:

Brake fluid leaks
Hydraulic brake systems can develop leaks in brake lines, hoses, or the master cylinder, leading to reduced braking efficiency and potential brake failure.
Brake pedal sponginess
Air can enter the hydraulic brake lines, causing the brake pedal to feel spongy and reducing braking performance.
Abs malfunction
The anti-lock braking system (ABS) can experience sensor failures or electronic control unit issues, leading to warning lights and potential loss of ABS functionality.
Warped brake rotors
Prolonged use and heat can cause brake rotors to warp, leading to vibrations and pulsations when braking.
Brake pad wear
Brake pads can wear out over time, causing reduced braking efficiency and increased stopping distances.
Engine overheating
The V-shaped, 8-cylinder engine can experience cooling system issues, leading to overheating, especially if the radiator, water pump, or thermostat fails.
Oil leaks
V8 engines, particularly in older models, can develop oil leaks from valve covers, oil pan gaskets, or rear main seals.
Misfiring cylinders
Ignition system problems, such as faulty spark plugs or ignition coils, can cause one or more cylinders to misfire, leading to rough running and reduced power.
Vacuum leaks
The complex intake manifold design of a V8 engine can develop vacuum leaks, affecting engine performance and fuel economy.
Exhaust manifold cracks
The V8 engine in the 2001 Jeep Grand Cherokee can develop cracks in the exhaust manifold, leading to exhaust leaks and increased engine noise.
Fuel pump failure
The fuel pump can fail or become weak over time, causing issues with fuel delivery and engine performance.
Transmission issues
The automatic transmission in the 2001 Jeep Grand Cherokee can experience shifting problems, slipping, or failure, particularly as the vehicle ages.
Electrical problems
Older vehicles like the 2001 Jeep Grand Cherokee can develop issues with the electrical system, including wiring problems, faulty sensors, and failing control modules.
