Known Problems
Some models the front brakes make a groan when coming to a stop due to improperly formulated brake pads. Replacing the front brake pads with an updated pad and turning the rotors will stop the noise.

On some models faulty front wheel bearings can cause a growling type noise from the front of the vehicle. Replacing both front wheel bearings is recommended for this repair.

The engine may develop and oil leak due to a porous engine block casting. The repair procedure is dependent on where the leak is located. Honda has released a service bulletin covering model years 1999-2003. Honda may offer assistance with repairs, determined on a case by case basis.

 

A seal in the 4 cylinder engine around the balance shaft tends to fall out, causing a large oil leak. There is a retaining device available to prevent the seal from falling out, which can be put in place during routine timing belt maintenance.

In colder climates moisture in the throttle control relay may freeze and cause the Check Engine light (MIL) to come on. Replacing all the relays is recommended.
On certain models the Powertrain Control Module (PCM) can misinterpret data from the coolant sensor and set a false Check Engine light (MIL). A software update from Honda is needed for this repair.

On certain models the Electronic Load Detector (ELD) can cause the head lights to dim and set a Check Engine Light. The ELD will need to be replaced for this repair.

A faulty gasket can cause coolant seepage from the water passage near the exhaust gas recirculation (EGR) valve. Replacing the gasket should correct this coolant leak.

Certain models in colder climates can exhibit a Check Engine light (MIL) when moisture freezes in the Manifold Absolute Pressure (MAP) sensor. Replacing the MAP sensor repairs this issue

A buzzing noise at freeway speeds can be caused by the engine and transmission resonating through the transmission shift cable. The Power Control Module (PCM) must be replaced to stop the resonating noise. 

There is an issue where the transmission can have a torque converter problem, or the computer monitoring the torque converter can misinterpret the information, and in either case this can cause the Check Engine Light (MIL) to illuminate. The problem will need to be diagnosed and depending upon what is causing the issue, the transmission will have to be repaired or the computer replaced.

A refrigerant leak may develop from the AC evaporator causing the AC to blow warm air. Verifying failure of this component is difficult. A good shop will use leak detection dye to verify a failing evaporator.

An AC refrigerant leak may develop from the condenser. Replacing a leaking condenser will be required to restore proper AC operation.
