The driver's side power master window switch (PMWS) evaluted during this investigation controls the power windows for all four doors, the power mirrors and door locks.The PMWS is located on the driver's side door panel.Chrysler advised that the PMWS was used on multiple vehicle platforms including model year (MY) 2011 Dodge Nitro, MY 2011-2012 Jeep Liberty and MY 2011 Chrysler Town & Country and Dodge Caravan for a total of approximately 425,000 vehicles.At the opening of the investigation, ODI identified two reports of fire near the vicinity of the PMWS on MY 2012 Jeep Liberty Vehicles.During the course of the investigation, ODI determined that one of the complaint fires was not likely caused by a PMWS failure as available evidence indicated the fire started in the dashboard as opposed to the door panel area.Accordingly, the report was removed from the above counts.In response to ODI's October 30, 2013 information request (IR) letter, Chrysler advised that it was only aware of the same two fire reports as ODI and that it had concluded one of the reports did not involve a PMWS failure.ODI has not identified any new subject vehicle reports involving PMWS fires during the course of the investigation.In addition to the reports alleging fire, ODI evaluated other reports and data related to PMWS failures including consumer complaints, field reports, law suits, and warranty claims provided by Chrysler in its response.ODI interviewed owners of complaint vehicles when additional information was required.In addition to the subject Jeep Liberty, ODI reports for the additional Chrysler vehicles that use the same PMWS were also reviewed.ODI identified two additional ODI complaints (see ODI 10523317 and 10474901) involving Chrysler minivans that alleged door fires that were, or may have been related to a PMWS failure.In discussions with ODI, Chrysler stated that it conducted a search for consumer complaints alleging PMWS related door fires on the additional vehicles that use the
