NHTSA Engineering Analysis EA11004

This investigation was prompted by Preliminary Evaluation (PE) 10-047 and was based on reports from consumers alleging that smoke and/or fire, as defined in 49 CFR ? 579.4, had occurred inside of the driver's door.The subject vehicles, model year (MY) 2006 CR-V, were manufactured at two different assembly plants.The vehicles manufactured in Japan (Sayama plant) were produced with a power window master switch (PWMS) supplied by the Thai Toyo Denso Company, Ltd. (Denso).The vehicles manufactured in the United Kingdom (UK, Swindon, England plant) were produced with a PWMS supplied by the Omron Corporation (Omron).Honda provided 45 reports on the subject vehicles responsive to this investigation.Of this number, 24 reports concerned Japan-built vehicles, 19 reports on UK-built vehicles, and two reports without a vehicle identification number which could not be identified by assembly plant.
