Speed control / throttle Vehicle recall #99V062001 · 1999 · 898,739 vehicles
What's wrong: 0l ohv/sohc engines and cruise control built from May 29, 1996 through March 4, 1999; 1998-1999 explorer/mountaineers equipped with 4.0l ohv/sohc or 5.0l engines or 1998-1999 rangers equipped with 2.5l, 3.0l ffv/efi or 4.0l engines and cruise control built from January 5, 1998 through March 4, 1999; 1998-1999 mustangs equipped with 3.8l, 4.6l 2-valve or 4-valve engines and cruise control built from March 2, 1998…
Why it matters: If the cruise control is used and this condition is present, a stuck throttle could result, which could potentially result in a crash.
The fix: Dealers will replace the cruise control cables. At the present time, the replacement cables are not available. Customers are being advised not to use the cruise control system until a replacement can be made.
Brakes (hydraulic) Vehicle recall #99V123000 · 1999 · 15,681 vehicles
What's wrong: The right front brake line to the hydraulic control unit (hcu) connection could separate causing the line to leak when the brake pedal is applied.
Why it matters: This could result in a loss of brake pressure to the front wheels, increasing the stopping distance.
The fix: Dealers will replace the flare nut on the brake line.
Latches & locks Vehicle recall #99V164000 · 1999 · 854,288 vehicles
What's wrong: The secondary hood latch May corrode at the latch pivot and stick in the open position.
Why it matters: If this occurs and the primary hood latch is either not engaged or is released, a hood fly-up could occur.
The fix: Dealers will install a secondary hood latch with components that are coated prior to assembly for improved latch pivot corrosion protection.
Electrical Vehicle recall #00V072000 · 2000 · 208,903 vehicles
What's wrong: 0l engines and all-time 4-wheel drive (a4wd) powertrains. The generic electronic module (gem) could experience a condition referred to as "lock-up" in which the gem controlled electronic functions (e.g., front windshield wipers, interior lights, 4x4 system, etc.) could not be turned on or, in some cases if the function is on, could not be turned off.
Why it matters: An inoperative windshield wiper system could affect driver visibility, increasing the risk of a crash.
The fix: Dealers will install a resistor in the gem circuit.
Speed control / throttle Vehicle recall #03V280000 · 2003 · 448,005 vehicles
What's wrong: On certain sport utility vehicles equipped with speed control and 4.0l sohc engines, if the strand cover on the speed control cable becomes flared at the end, the speed control cable May bind when the speed control is activated.
Why it matters: The throttle return spring force May not be sufficient to overcome the binding condition when the speed control is disengaged. Braking function would be maintained though stopping distances May be increased.
The fix: Dealers will inspect the speed control cable and, if necessary, replace it. Owner notification began August 29, 2003. Owners should contact Ford at 1-800-392-3673.
Seats Vehicle recall #03V281000 · 2003 · 1,552,880 vehicles
What's wrong: On certain sport utility vehicles equipped with high back seats, the upper bolt on the driver's side high back seat, that attaches the seat recliner mechanism to the seat back frame, could fracture. If the bolt fractures and does not jam in the seat back frame, the seat back May recline until it makes contact with an object behind the seat, such as the second row seat cushion.
Why it matters: The driver could potentially lose contact with the steering wheel or foot pedals during such an event, increasing the risk of a crash.
The fix: Dealers will replace the driver seat upper bolt with a metal spacer and bolt. In addition, seats with tubular back frames will have the fully threaded lower recliner bolt replaced with a partially threaded bolt. Owner notification began on August 29, 2003. Owners should contact Ford at…
Speed control / throttle Vehicle recall #07V336000 · 2007 · 3,600,000 vehicles
What's wrong: On certain pickup trucks, passenger vehicles, sport utility vehicles, and motor homes chassis, the speed control deactivation switch May, under certain conditions, leak internally and then overheat, smoke, or burn.
Why it matters: This could result in an underhood fire.
The fix: Dealers will install a fused wiring harness. Owners of the passenger cars included in this campaign will be instructed to return their vehicles to their dealers to have the speed control deactivation switch disconnected as an interim repair. As soon as repair parts are available (expected October…
2 aftermarket equipment / tire recalls replacement parts sold to fit this car, not the car itself
Tires Tire recall #00T005000 · 2000 · 14,400,000 vehicles
What's wrong: Tire description: firestone wilderness at, size p235/75r15, produced at the decatur, illinois tire plant and all firestone radial atx and radial atx II tires, size p235/75r15. Operation of these tires at low inflation pressures, high speed, and in hot weather, can contribute to separation of the tire tread.
Why it matters: If the tread separates from the tire, the driver can lose control of the vehicle, possibly resulting in a crash causing injury or death.
The fix: The replacement/reimbursement program for this campaign expired on August 29, 2001. However, customers should contact firestone customer service at 1-800-465-1904 for possible assistance.
Fuel system Equipment recall #06E056000 · 2006 · 58,640 vehicles
What's wrong: Certain aftermarket fuel filters sold under the purolator brand name, p/n f65277, shipped from January 16 through June 2, 2006, for use on the above listed passenger vehicles. Due to incorrect design, the quick connectors May not fully seat with the tube interface, even though the person making the connection May believe that the quick connector is fully attached.
Why it matters: Failure of this connection could lead to fuel spillage and, in the presence of an ignition source, a fire could occur.
The fix: Ufi will notify owners and replace the filters free of charge. The recall began on August 4, 2006.
