The National Highway Traffic Safety Administration (NHTSA) began an investigation into Ford’s 2004-2006 F-150 trucks last September, which ended in a recall of about 140,000 trucks. The problem was being blamed on an improperly installed wire in the steering column that could chaff and short out. The result was an illuminated seat belt lamp and the potential that the airbag could deploy without warning.

Under pressure from the NHTSA, Ford will be expanding the recall to include almost 1.2 million 2004-2006 Ford F-150 trucks and some 2006 Lincoln Mark LT vehicles. Owners wanting more information can contact the Ford Motor Company customer relationship center at 1-866-436-7332.
