Chronology of Defect February 21, 2023: Mazda received notice from the Ford Motor Company regarding the possibility of a mis-positioned passenger frontal air bag inflator. This may occur during completion of the recall remedy intended to resolve a potential air bag rupture from the original Takata inflator. Ford discovered their technicians did not follow the recall repair instructions completely. Note that Mazda’s MY2004-2006 B-series trucks are manufactured by Ford Motor Company and share the same platform as Ford’s MY2004-2006 Ranger trucks. February 22, 2023, to March 1, 2023: Mazda began internal discussions to determine assessment of field conditions. March 2, 2023, to April 30, 2023: Evaluations were conducted based on available data; collected and reviewed internal data, repair instructions, other vehicles. May 1, 2023, to May 15, 2023: Continued assessing field conditions from available sources and other affected vehicles. May 11, 2023: Mazda modified the warranty claim process for active recalls 1817L (17V806) and 2318A (18V039). The new process requires photos after repairs are completed to verify proper installation, close the recall, and reimburse dealership claims by Mazda’s warranty
department.
May 17, 2023: Mazda met with NHTSA to propose a voluntary campaign to understand
conditions with Mazda dealers in the field. June 2, 2023: NHTSA provided added guidance and confirmed support of a voluntary campaign.

T (949) 727-1990 June 5, 2023, to July 27, 2023: This concern was cascaded through Mazda’s internal process that
reviews and approves voluntary campaign programs. July 28, 2023: Mazda approves Special Service Program “SSPC9”.
July 29, 2023, to August 30, 2023: Mazda prepared for SSPC9 with a target of 249 vehicles for inspection to confirm positioning of the frontal air bag inflator. This included pulling applicable VINs and developing a list of vehicle owners most likely to respond to the voluntary campaign. August 31, 2023, to November 23, 2023: Through the new warranty claim process and not the planned voluntary campaign, four mis-installed cases were identified. Interviews were conducted and it was verified that technicians did not follow the revised repair instructions. In these four cases, Mazda had dealerships tow vehicles back to be repaired properly. November 23, 2023, to November 29, 2023: Mazda opted to cancel the field inspection program under SSPC9 and move toward proactive field action. December 5, 2023: Mazda held a Quality Audit Committee meeting to review all available information to date. Mazda decided to conduct a proactive field action on MY2004-2006 B­ Series trucks that received previous recall remedy repairs. December 21, 2023: Mazda has filed an amendment to adjust the Planned Owner Notification
Begin and End Dates from January 12, 2024, to February 10, 2024. To date, Mazda has not received any field information reports. Mazda is not aware of any accidents or injuries as a result of this concern.
