NHTSA investigations into the engine on the Civic

Electrical · model years 2002 to 2003

Low beam headlights stop illuminating. Closed sep 17, 2012, led to recall 12V-136.

NHTSA summary
This investigation was prompted by Preliminary Evaluation (PE) 11-017, and was based on reports from consumers alleging that both low beam headlights stopped illuminating simultaneously.Some complainants also reported that the combination switch (switch) that controls the headlights and turn signals, and/or its electrical wiring harness connector were damaged by overheating.ODI's PE information request letter asked Honda for certain data on model years (MY) 2002-2006 CR-V, 2003-2008 Pilot, 2003-2008 Element, 2001-2005 Civic, and 2000-2001 S 2000 vehicles.Analysis of complaint and Honda data show that a complete low beam headlight circuit failure occurs in models with 2-bulb headlight systems (i.e., a single bulb on each side for high and low beam).Models with 2-bulb systems include MY 2002-2004 CR-V, 2003-2005 Pilot, 2001-2003 Civic, and 2003-2008 Element.Models with 4-bulb headlight systems (i.e., two bulbs on each side, one for high and one for low beam) have different electrical circuits for the headlights and do not experience the same failure mechanism as the 2-bulb system.MY 2000-2001 S 2000 models with 2-bulb high intensity discharge headlights also have different electrical circuits for the headlights and do not experience the same failure mechanism.Honda introduced the 4-bulb headlight system in CR-V in MY 2005, in Pilot in MY 2006, and in Civic in MY 2004.On March 29, 2012 Honda submitted a defect information report (DIR) to recall 554,428 vehicles, including MY 200

Ignition shift interlock. Closed oct 14, 2010, led to recall 10V-364.

NHTSA summary
On August 4, 2010, American Honda Motor Co. (Honda) submitted a Defect Information Report (DIR) to NHTSA regarding a ignition interlock defect in approximately 384,220 model year (MY) 2003 Honda Accord and Civic and MY 2003 and 2004 Honda Element vehicles with automatic transmissions (Recall 10V-364).In a September 22, 2010 supplemental DIR, Honda expanded the scope of the recall population based on manufacturing and complaint data.The total population for the complete recall is approximately 551,498 vehicles.The information listed in this closing report refers only to the subject vehicles, MY 2003 Accords with automatic transmissions.According to Honda's DIR, Under certain conditions the interlock lever of the ignition switch may unexpectedly deform, which can allow the interlock function of a vehicle with an automatic transmission to be defeated if the driver does not follow the typical shut-down procedure of shifting the gear selector to the Park position before rotating the ignition key to the off position. Removal of the ignition key when the gear selector of a vehicle with an automatic transmission has not been shifted to the Park position can allow the vehicle to roll away, increasing the risk of a crash.Honda's dealers will be instructed to inspect the ignition interlock switch and, if necessary, replace the original interlock pin and lever within the ignition switch and replace them with new, redesigned parts.This investigation is closed.

Should you keep driving it?

This page can't tell you that. 0 of 26 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
