One complaint can name several systems, so shares can add to more than 100 percent.
Model-generated complaint tags: This model year has not been tagged.
Defect: 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. (excerpt)
Consequence: THIS COULD RESULT IN AN UNDERHOOD FIRE. (excerpt)
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 (excerpt)
Defect: 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.
Consequence: THE DRIVER COULD POTENTIALLY LOSE CONTACT WITH THE STEERING WHEEL OR FOOT PEDALS DURING SUCH AN EVENT, INCREASING THE RISK OF A CRASH.
Remedy: 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 1-800-392-3673.
Defect: 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.
Consequence: 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.
Remedy: 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.
Do not drive: No. Park outside: No.

Notes on this record
Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
