- Recall #09V399000Ford is recalling model years 1995-2003 windstar, 2000-2003 excursion diesel, 1993-1997 and 1999-2003 F-250 sd through F-550 sd diesel, 1992-2003 E-150 through E-550, 1995-2002 explorer, 1997 and 2002 mercury mountaineer, 1995-1997 and 2001-2003 ranger, and 1994 F53 vehicles equipped with the texas instruments speed control deactivation switch (scds). The scds may leak internally and then overheat, smoke, or burn.
- Recall #00V422000Vehicle description: sport utility vehicles equipped with 4.0L sohc engines and still retain the original throttle body (part numbers 97JF-9E926AB or 97JF-9E926-AC). Some of the original throttle bodies installed allowed a gap between the plate and bore to be built too narrow. This reduced clearance allowed the engine deposits normally present in the throttle body to contact or bridge the gap. If the engine deposits bridged the gap between the throttle plate and bore and then hardened, on the initial application of the accelerator pedal after the engine has cooled, the operator would need to apply additional force to the accelerator pedal to break the bridge.

AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.

NHTSA recall #09V399000October 13, 20094,500,000 vehicles affected
vehicle speed control
Ford is recalling model years 1995-2003 windstar, 2000-2003 excursion diesel, 1993-1997 and 1999-2003 F-250 sd through F-550 sd diesel, 1992-2003 E-150 through E-550, 1995-2002 explorer, 1997 and 2002 Mercury Mountaineer, 1995-1997 and 2001-2003 ranger, and 1994 F53 vehicles equipped with the texas instruments speed control deactivation switch (scds). The scds may leak internally and then overheat, smoke, or burn.
A vehicle fire could occur with or without the engine running.
Remedy
Ford will notify owners that dealers will install a fused wiring harness in line with the scds. On 1999-2003 windstar vehicles with a leaking scds, dealers will also inspect the ABS control module connector and repair as necessary. Repairs will be completed free of charge. The safety recall began on october 27, 2009. Owners may contact Ford at 1-888-222-2751.
NHTSA recall #00V422000December 27, 2000220,000 vehicles affected
vehicle speed control
Vehicle description: sport utility vehicles equipped with 4.0L sohc engines and still retain the original throttle body (part numbers 97JF-9E926AB or 97JF-9E926-AC). Some of the original throttle bodies installed allowed a gap between the plate and bore to be built too narrow. This reduced clearance allowed the engine deposits normally present in the throttle body to contact or bridge the gap. If the engine deposits bridged the gap between the throttle plate and bore and then hardened, on the initial application of the accelerator pedal after the engine has cooled, the operator would need to apply additional force to the accelerator pedal to break the bridge.
This could result in engine surge when the accelerator pedal breaks free.
Remedy
Dealers will replace the original throttle bodies.
NHTSA recall #00V402000November 28, 2000810,000 vehicles affected
suspension
Vehicle description: sport utility vehicles. Under certain conditions, a front sway bar link Can fracture.
Vehicle handling could be affected, increasing the risk of a crash.
Remedy
Dealers will replace both the left and right front sway bar links.
NHTSA recall #98V060000March 19, 1998320,000 vehicles affected
fuel system, gasoline: delivery: hoses, lines/piping, and fittings
Vehicle description: multi-purpose passenger vehicles equipped with 4.0L single overhead cam engines. The engine fuel lines Can be damaged if the vehicle is jump started and the ground cable is attached to the fuel line bracket that is located near the battery. Since the bracket is not grounded, the stainless steel fuel line braid could act as a ground potentially overheating the ptfe inner liner of the fuel line resulting in damage to the fuel line.
The fuel lines Can leak, and in the presence of an ignition source, a fire could potentially result.
Remedy
Dealers will install a warning label on the fuel line bracket advising owners not to use it for a jump start ground. Also a revised bolt will be installed in the alternator bracket to provide a convenient jump start ground location.
NHTSA recall #97V137000August 19, 19972,200 vehicles affected
structure: body: hatchback/liftgate: support device/strut
Vehicle description: multi-purpose passenger vehicles. The liftgate assist gas cylinder bracket on the right hand bodyside outer panel was incorrectly welded.
The gas cylinder bracket may not properly support the liftgate increasing the risk of personal injury.
Remedy
Dealers will reinforce the bracket attachment with two pop rivets.
NHTSA recall #97V074000April 30, 199723,000 vehicles affected
vehicle speed control
Vehicle description: multi-purpose passenger vehicles equipped with 5.0L engines originally sold or currently registered in the states of alaska, idaho, iowa, maine, michigan (upper peninsula only), minnesota, montana, nebraska, new hampshire, new york, north dakota, south dakota, vermont, wisconsin, and wyoming. These vehicles, when operated for extended periods of time at highway speeds and temperatures below -20 degrees farenheit, do not return to idle due to ice in the throttle body.
Although the vehicle Can be controlled by either applying the service brakes or shifting the transmission to neutral, increased brake pedal efforts or some increase in stopping distance Can result.
Remedy
Dealers will install a revised pcv system with water heated vacuum source.
