Ignition interlock failure - rollaway. Closed jan 14, 2013, led to recall 12V-573.

NHTSA summary

On December 10, 2012, Honda Motor Company submitted a defect information report to NHTSA regarding ignition interlocks in approximately 576,117 model year MY) 2003 through 2004 Honda Pilot and Odyssey vehicles that are the subject of this investigation and 231,044 MY 2003 through 2006 Acura MDX vehicles (Recall No. 12V-573).Honda's report states that a design change to the ignition switch used in the recalled vehicles reduced the range of rotation for the ignition switch from 160 degrees in earlier designs to 125 degrees without a corresponding change to the ignition interlock blocking mechanism.The result was that excessive rotational force could damage a lever that would allow the driver to remove the ignition key that was in a position other than the Park position, which may allow the vehicle to roll away.ODI identified 176 complaints related to the alleged defect, including 48 roll away crashes.Threeof the incidents resulted in the following injuries to pedestrians:1) a broken foot and torn Achilles tendon; 2) a fractured fibula and crush injuries to a shin area; and 3) an incident requiring unspecified treatment at a hospital emergency room.This investigation is closed.The VOQs associated with this investigation are: 10486515, 10486393, 10486100, 10485010, 10482229, 10482091, 10481169, 10481105, 10481079, 10481027, 10480804, 10480648, 10480099, 10480009, 10479934, 10479695, 10479561, 10479517, 10479494, 10479484, 10479437, 10479421, 10479409, 10479343, 10478916, 10478876

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

What owners wrote

“The vehicle won't start, electrical system failure. Sometimes the electrical system fails when the car is driving/it will stall on the road. It was predicated by the alarm going off intermittently and without provocation (in the middle of the night/etc).”
Filed Aug 21, 2026

“The vehicle has routinely had issues restarting from auto idle. When the vehicle turns off in traffic at a stop or stopped at a red light, then it will not restart and the vehicle will essentially be dead for several minutes and unable to be turned on or moved.”
Filed Apr 27, 2026

“Car does not want to start even though the batter and alternator are good (tested by tow truck company). Restarts fine once batter is disconnected and then reconnected again. This has now happened twice.”
Filed Dec 20, 2025

“While stopped at an intersection, the car died, the transmission shifted to neutral automatically and the radio would not turn on. The AGM battery was replaced approximately one year ago when a similar situation took place.”

Should you keep driving it?

This page can't tell you that. 0 of 30 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.
