The Dearborn, Mich.-based automaker previously had recalled nearly 6 million vehicles beginning in January 2005 because of engine fires linked to the cruise control systems in trucks, SUVs and vans.
"Customers remain concerned about the long-term durability of the speed control system and about the safety of their vehicles," said Ford spokesman Dan Jarvis.
He said the automaker had received "a few reports of fires" in Ford Crown Victoria passenger cars prior to the recall. He did not have a precise number.
The recall involves the following vehicles: 1998-2002 Ford Ranger, 1992-1997 Lincoln Town Car, 1992-1997 Ford Crown Victoria, 1992-1997 Mercury Grand Marquis, 1993-1998 Lincoln Mark VIII, 1993-1995 Taurus SHO, 1999-2001 Ford Explorer and Mercury Mountaineer.
Also covered are the 2001-2002 Ford Explorer Sport, 2001-2002 Ford Explorer Sport Trac, 1992-1993 E150-350 vans, 1997-2002 E150-350 vans, 1993 Ford F-Series pickups, 1993 Ford Bronco, 1994 Mercury Capri, 2003-2004 Ford F-150 Lightning, and 1995-2002 Ford F53 motor homes.
An additional 177,000 vehicles in Canada, Mexico and Europe are covered by the recall.
Jarvis said there have been no deaths, injuries or accidents associated with the recall.
It was Ford's sixth recall, involving a total of more than 10.4 million vehicles, conducted since 1999 because of problems with the speed control system, according to the National Highway Traffic Safety Administration.
