2003 Honda Civic Si Problems

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.

Plugged moon roof drains can cause a water leak inside the car, usually over the head of the driver or passengers head when turning a corner. Cleaning the drains will fix this problem.

Damaged engine mounts can lead to vibration and roughness felt in the steering wheel. A rattle in the dash and engine area may also be heard. Replacement of damaged mounts will commonly correct these issues.

2003 Honda Civic Si Recalls

Honda is recalling 2003 Accord and Civic, and 2003–2004 Element models due to a defective interlock lever in the ignition switch. The lever may deform, which will defeat the interlock function on vehicles with an automatic transmission. This may cause a vehicle that has not been shifted into the "Park" position to roll away, increasing the risk of a crash. Dealers will remove the interlock pin and lever and replace them with new components, free of charge.

Honda has recalled 2001-2003 Civic, 2002-2003 Civic SI, 2001-2002 Accord, 2002 CR-V, 2002 Odyssey, 2003 Pilot, 2002-2003 Acura TL, and 2003 Acura CL vehicles because the driver's side air bag inflator may produce excessive internal pressure. This could cause the inflator to rupture if the air bag deploys. Metal fragments may pass through the air bag material and cause injury to vehicle occupants. Dealers will replace the driver's side air bag inflator.
