Known Problems

The ABS modulator valve assembly (hydraulic unit) may develop a brake fluid leak.  This can result in illumination of the ABS warning light and in certain cases, loss of braking ability.

 

A foul smell from the AC system can indicate mold growth on the AC evaporator.

The balance shaft seal 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.

The AC evaporator can develop a refrigerant leak. The AC system will not blow cold air if this happens.

Front compliance (lower control arm ) bushings tend to crack and break requiring replacement.

On some models a mis-manufactured AC evaporator core can cause the AC to cool poorly. The AC evaporator needs to be replaced for the AC to cool properly.

Accords powered by the V6 engine had a defective timing belt tensioner that could result in excess "slack" in the timing belt. This could cause premature timing belt failure, which could result in serious engine damage.

If the idle is higher than normal when the engine is cold and the Check Engine Light is on, the powertrain control module (PCM) may need a software update to fix the concern.

In colder climates, coolant can leak from the connecting pipe.

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.

Rear sway bar end links are known to break.

The throttle body can accumulate carbon deposits causing the throttle to stick or pop when first accelerating after the vehicle sits for a while. Performing a throttle body service will generally correct this problem.

The AC evaporator and/or the AC condenser can develop a refrigerant leak. The AC system will not blow cold air if this happens. Diagnoses, commonly using leak detection dye will be necessary to determine the source of the leak.

Head gasket failure is not uncommon if the engine overheats. If the temperature climbs above the normal operating temperature, turn the heater on the hottest setting, pull over to a safe location, and shut the engine off to allow the engine to cool down.

The head gaskets are prone to fail if the engine overheats. When the temperature climbs above the normal operating temperature, turn the heater on the hottest setting, pull over, and shut the engine off to allow the engine to cool down.
