2004 Honda Accord Problems
Head Lights Dim, Check Engine Light On
A faulty Electric Load Detector (ELD) can cause the head lights to dim and/or illuminate the Check Engine Light. A failed ELD will require replacement.
Vibration When Braking Due to Rotor Problem
The front brake rotors can warp and cause a vibration when braking. The rotors will need to be machined or in cases where they are worn to thin, replaced to correct this issue.
Check Engine Light and Higher Than Normal Idle Cold
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.
Knocking Noise From Rear of Vehicle
One or both of the rear sway bar end links may break resulting in a knocking noise from the rear of the vehicle.
ABS Modulator May Leak Air and Cause Low Brake Pedal
The ABS modulator (hydraulic unit) can leak air into the brake system and cause a low brake pedal. A new ABS modulator will be needed if it is diagnosed to be the source of the leak.
Check Engine Light Due to Failed Air Fuel Sensor
Issues with the air fuel sensor (oxygen sensor) can set a Check Engine Light. A failed sensor will need to be replaced for this repair.
The Brake Pedal May Feel Hard After Vehicle Has Set For Extended Time
If the brake pedal feels hard the first time it is pressed in the morning, it could be due to a problem with the vacuum supply hose for the brake booster. A revised brake booster hose is available to address this concern.
ABS Light Due to Rear Wheel Speed Sensor Fault
Occasionally, the anti-lock brake (ABS) warning light may illuminate. This could be due to a faulty rear wheel speed sensor. The sensor design has been updated and revised parts are available to correct this problem.
Plugged Moon Roof Drains May Cause Water Leak
Plugged moon roof drains can cause a water leak inside the car. The water will usually leak onto the driver's or passenger's head when the car turns a corner.
Defective Timing Belt Tensioner May Cause Premature Timing Belt Failure
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.
Failed VTEC oil pressure switch
Engine hesitated while accelerating from a stop. The check engine light (CEL) came on immediately. Autozone pulled the code of P2647. I replaced the oil pressure switch (37250-PNE-G01) and the o-ring (91319-PAA-A01).
Front Compliance Bushings May Crack
Front compliance (lower control arm ) bushings tend to crack and break requiring replacement.
Radio/Climate Control Display May Go Dark
The radio and climate control display can go dark on some models. It will be necessary to replace the affected unit to correct this concern. Some customers have reported receiving help from Honda regarding this repair.
Problems Shifting Into 3rd Gear
Some models have shift quality problems when shifting into third gear. A new "third gear set" from Honda will address this issue.
Broken Door handle cable stay
The green plastic stay that secures the door handle release cable can break leaving you unable to open your door from the inside. Cheap fix if you replace it yourself... $15
