Problems:
Brake fluid leak
Hydraulic brake systems can develop leaks in the brake lines, calipers, or master cylinder, leading to reduced braking efficiency.
Brake fade
Overheating of the brake components can cause a loss of braking power, particularly under heavy or prolonged braking conditions.
Worn brake pads or shoes
Frequent use can wear down brake pads or shoes, resulting in reduced braking performance and potential damage to rotors or drums.
Master cylinder failure
The master cylinder can wear out or develop internal leaks, leading to a spongy brake pedal or complete brake failure.
Engine overheating
In-line 4-cylinder engines can suffer from overheating issues due to coolant leaks, radiator problems, or a failing water pump.
Fuel injector problems
Electronic Fuel Injection (EFI) systems can have issues with clogged or malfunctioning fuel injectors, leading to poor performance or engine misfires.
Timing chain wear
The 22R-EC engine uses a timing chain that can stretch or wear out over time, potentially leading to timing issues and engine performance problems.
Oil leaks
Common spots for oil leaks include the valve cover gasket, oil pan gasket, and front or rear main seals.
Head gasket failure
The 22R-EC engine is known for occasional head gasket issues, which can lead to coolant mixing with oil and causing engine damage.
Vacuum leaks
Vacuum hoses can become brittle and crack over time, leading to rough idling or poor engine performance.
Throttle body issues
The throttle body in electronic fuel injection systems can become dirty or malfunction, causing poor throttle response or stalling.
Aging electrical components
As the vehicle ages, electrical components like sensors, wiring, and connectors can degrade, leading to various engine and performance issues.

Problems:
Oil leaks
The 3RZ-FE engine in the 2000 Toyota 4-Runner is known to develop oil leaks, particularly from the valve cover gasket, oil pan gasket, and front and rear crankshaft seals.
Head gasket failure
This engine can sometimes suffer from head gasket failure, leading to coolant leaks and potential engine overheating.
Timing chain wear
Over time, the timing chain and its associated components can wear out, leading to noisy operation and potential timing issues.
Fuel injector issues
Fuel injectors in the 3RZ-FE engine can become clogged or fail, causing poor engine performance, misfires, and reduced fuel efficiency.
Idle control valve problems
The idle air control valve can malfunction, leading to unstable idle speeds and potential stalling.
Mass air flow (maf) sensor problems
A faulty MAF sensor can cause incorrect air-fuel mixture readings, resulting in poor engine performance and fuel economy.
Ignition coil failure
The ignition coils in this engine can fail, causing misfires and rough running conditions.
Egr valve clogging
The EGR (Exhaust Gas Recirculation) valve can become clogged with carbon deposits, leading to engine performance issues and increased emissions.
Coolant leaks
Radiator and hoses can develop leaks, leading to potential overheating issues if not addressed promptly.
