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.
Recalls
NHTSA recall #08V051000February 4, 2008225,000 vehicles affected
vehicle speed control: cruise control
Ford is recalling 225,000 my 1992-2003 econoline, my 1993-1995 taurus sho, my 1992-1998 crown victoria, my 1993 bronco, f-series, my 1995-1997 f-series super duty stripped chassis, my 1992-1998 Mercury Grand Marquis, and my 1992-1995 Lincoln town car vehicles. The affected vehicles were previously repaired using a wiring harness that is not compatible with the vehicle circuit polarity.
As a result, the fuse is located in the output circuit rather than in the intended input power feed circuit, and may not offer the intended protection in the event of an electrical short to ground.
Remedy
Dealers will install a new wiring harness, or replace the mating electrical component. The recall began on february 18, 2008. Owners may contact Ford at 1-800-392-3673.
NHTSA recall #07V336000August 3, 20073,600,000 vehicles affected
vehicle speed control
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.
This could result in an underhood fire.
Remedy
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 2007), owners will be instructed to return to the dealers for installation of a fused wiring harness. The recall began on august 13, 2007, and mailing completed by september 19, 2007. Owners may contact Ford at 1-888-222-2751.
NHTSA recall #99V124000May 19, 1999262,695 vehicles affected
electrical system
Vehicle description: passenger vehicles. The speed control deactivation switch Can develop a resistive short in the electrical circuit that could potentially result in an underhood fire. A fire is possible both when the vehicle is running and when the vehicle engine is off. Also, the short could disable the speed control system or cause the brake light fuse to open.
A fire Can originate in the left front underhood area.
Remedy
Dealers will install a new speed control deactivation switch and connector shell. Owner notification began may 20, 1999.

About this data
NHTSA complaints and recalls through October 2026. Complaints are counted once each, however many components they name. Original complaints are on NHTSA's page for the 1993 Mercury Grand Marquis.
Problem groups are formed by AI and may be approximate. BrakeNews flags unusual complaint patterns; they are not official defect findings. Investigation reports are written and checked by AI, with no human review. Owner reports do not establish that a defect exists.
