Ford Fusion Electronic Throttle Body Malfunction Analysis

Owner Reports

Within Ford's North American Customer Service Operations, the Customer Relationship Center (CRC) facilitates communication with customers, dealerships, and Ford Motor Company. The CRC handles inquiries, suggestions, and concerns from Ford and Lincoln-Mercury vehicle owners. These contacts are summarized and entered into the FMC360 database. Each contact report is assigned a "symptom code" or category describing the customer's concern. Ford's experience indicates that a significant percentage of owner contacts lack sufficient information for technical assessment. FMC360 reports are useful for identifying trends but are not empirical equivalents of confirmed incidents or dealership diagnoses.

Ford electronically searched FMC360 for the following criteria:

Vehicles: Subject & Peer vehicles manufactured for sale or lease in the United States, District of Columbia, Puerto Rico, Northern Mariana Islands, Guam, American Samoa and the Virgin Islands.

Date Parameters: January 1, 2008 through March 25, 2013.

Types of Contacts: All, including suspended data, canceled contacts and inquiries.

FMC360 Symptom Code(s):

Field Reports

Ford's Vehicle Service & Programs Office manages vehicle service and technical support, including field actions. This office is the primary source of vehicle concern information from Ford and Lincoln-Mercury dealerships, field personnel, and other sources. Information is maintained in the Common Quality Indicator System (CQIS) database, compiled from over 40 company sources. CQIS reports are assigned a "symptom code" or category reflecting the nature of the concern.

In July 2011, FCSD launched a new coding system for CQIS. All reports maintained prior to this change have been recoded.

Ford electronically searched CQIS using the following criteria:

Vehicles: Subject & Peer vehicles manufactured for sale or lease in the United States, District of Columbia, Puerto Rico, Northern Mariana Islands, Guam, American Samoa and the Virgin Islands.

Date Parameters: January 1, 2008 through March 25, 2013.

Types of Contacts: All, including suspended data, canceled contacts and inquiries.

FMC360 Symptom Code(s):

OASIS MESSAGES

FCSD communicates vehicle and service information, including warranty and Extended Service Plan coverage, and technical repair information to North American Ford and Lincoln-Mercury dealers via OASIS. OASIS is an electronic link covering North American Ford and Lincoln-Mercury cars and light trucks, and medium and heavy-duty Ford trucks for the ten most current model years. Technical diagnostic and repair information is contained in Special Service Messages (SSMs) and Technical Service Bulletin (TSB) titles and brief summaries. Dealers cannot access brief summaries.

SSMs and TSB titles are coded by model year, vehicle line, and other attributes. Dealers typically search by VIN and applicable Service Codes. Inactive or superseded SSMs and TSB titles remain accessible to Ford employees but not dealers. Dealers can also search for recalls by VIN in OASIS. Recall information cannot be searched by Service Codes.

In July 2011, FCSD launched a new coding system for OASIS. Active SSMs and TSB titles were recoded. Inactive and superseded titles are maintained under the old system.

Ford searched Global OASIS using both new and old OASIS service codes for active, inactive, and superseded TSB titles and SSMs using the following search criteria:

Vehicles: Subject & Peer vehicles manufactured for sale or lease in the United States, District of Columbia, Puerto Rico, Northern Mariana Islands, Guam, American Samoa and the Virgin Islands.

Date Parameters: January 1, 2008 through March 25, 2013.

Types of Contacts: All, including suspended data, canceled contacts and inquiries.

FMC360 Symptom Code(s):

OASIS 2 and Global OASIS cannot perform electronic word searches; results are reviewed manually. The OASIS database also contains Broadcast Messages, which are typically directed to all dealerships for notifications of new SSMs/TSBs or non-technical announcements. Broadcast Messages cannot be searched by OASIS service codes and are only retrievable while active (2-4 days). Ford did not search for Broadcast Messages as they are expected to be non-substantive or duplicative.

Internal Service Messages

FCSD maintains fleet and technical telephone "hotlines." During the early stages of identifying and resolving vehicle concerns, hotline personnel may draft Internal Service Messages (ISMs) on CQIS for internal use. ISMs are assigned a CQIS "symptom code" or category. An ISM can form the basis for an oral response to a dealer or fleet technician. ISMs are not made available electronically to dealers or fleets.

Ford searched CQIS for active ISMs using the following criteria:

Vehicles: Subject vehicles manufactured for sale or lease in the United States, District of Columbia, Puerto Rico, Northern Mariana Islands, Guam, American Samoa and the Virgin Islands.

Date Parameters: January 1, 2008 through March 25, 2013.

Field Review Committee

Ford's Field Review Committee reviews potential field service actions, including safety recalls and customer satisfaction programs, and recommends actions to corporate management. A Vehicle Service & Programs representative serves as Secretary to the committee. Following approval of a field service action, the Vehicle Service & Programs Office prepares and launches the action. A copy of the communication to dealers, fleets, and Regional offices is maintained in the committee files.

Warranty

Ford's Analytical Warranty System (AWS) contains warranty claims and vehicle information for model years 1991 and forward for North America, and model years 1992 and forward for Europe.

Ford performed a search of AWS for potentially responsive reports using the following search criteria:

Vehicles: Subject & Peer vehicles manufactured for sale or lease in the United States, District of Columbia, Puerto Rico, Northern Mariana Islands, Guam, American Samoa and the Virgin Islands.

Date Parameters: January 1, 2008 through March 25, 2013.
