10V161000 · Seats:front Assembly:recliner

Apr 20, 2010

FORD IS RECALLING CERTAIN MODEL YEAR 2010 FUSION, EXPLORER, EXPLORER SPORT TRAC, AND MERCURY MILAN AND MOUNTAINEER VEHICLES MANUFACTURED BETWEEN DECEMBER 15, 2009 THROUGH FEBRUARY 3, 2010 EQUIPPED WITH FRONT SEAT MANUAL RECLINERS. THESE VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 202, "HEAD RESTRAINT." THE RECLINER GEAR PLATE TEETH MAY BE OUT OF DIMENSION SPECIFICATION WHICH COULD RESULT IN LIMITED PAWL TO GEAR PLATE TOOTH ENGAGEMENT.

Consequence & remedy

Consequence: IN THE EVENT OF A CRASH, THE SEATBACK AND HEAD RESTRAINT MAY MOVE REARWARD, INCREASING THE RISK OF INJURY.

Remedy: DEALERS WILL REPLACE THE MANUAL RECLINERS FOR BOTH POWER AND MANUAL SEATS FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN ON OR BEFORE APRIL 30, 2010. OWNERS MAY CONTACT FORD AT 1-866-436-7332.

AQ10001 · Fleet Vehicle Recall Completion Audit

Opened Nov 18, 2010 · Closed Dec 28, 2015

Status: closed (inferred from source dates) · Unknown Or Other

On November 18, 2010, NHTSA's Recall Management Division (RMD) opened an audit query (AQ10-001) to investigate recall remedy completion by rental car companies on safety recall campaigns.It was expected to provide the agency an indication of how completely and how quickly rental car fleets perform necessary recall-related remedies on the vehicles owned and then rented/leased for use on the roadways.RMD queried three (3) major motor vehicle manufacturers (Ford, Chrysler, and General Motors) and requested data regarding completion figures for fifteen (15) discreet safety recalls.Analysis of this data demonstrated that rental car recalls completion was neither complete nor consistent.The rental car companies representing the largest market share in the industry were then queried as to their respective policies for the rental, lease, and sale of vehicles with open recalls.The data and responses from the manufacturers and the rental car companies can be found in the document repository by accessing the ?Associated Documents link above.In December 2015, Congress enacted the Fixing America's Surface Transportation (FAST) Act.One section of the Act prohibits rental car companies from renting, leasing, or selling motor vehicles subject to open safety recalls.With the passage of the FAST Act and its prohibition, there is no continuing need for the agency to investigate rental car recall completions.Accordingly, this investigation is closed.The agency reserves the right to open any future investigations, including audits of individual recalls, or groups of recalls, or rental car companies, to examine more closely safety recalls performance and completion issues in this area.
