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:
Overheating
The 3VZ-E engine can suffer from overheating issues, often due to a malfunctioning thermostat, clogged radiator, or a failing water pump.
Head gasket failure
This engine is known for head gasket problems, which can lead to coolant leaks, overheating, and poor engine performance.
Timing belt issues
The timing belt in the 3VZ-E engine needs regular maintenance. If it fails, it can cause significant engine damage.
Oil leaks
Common oil leak points include the valve cover gaskets and the oil pan gasket, leading to oil stains and potential engine damage if not addressed.
Fuel injector problems
Electronic fuel injection systems can suffer from clogged or failing injectors, causing rough idling, poor fuel economy, and reduced performance.
Vacuum leaks
Vacuum leaks can cause rough idling and poor acceleration. Common areas include vacuum hoses and intake manifold gaskets.
Ignition system issues
Problems with the distributor, spark plugs, or ignition wires can lead to misfires, rough running, and difficulty starting the engine.
Egr valve failure
A clogged or malfunctioning EGR valve can cause rough idling, increased emissions, and reduced engine performance.
