Over one million cars manufactured by the US-based Ford Motor Company have been recalled because they are at risk of catching on fire, Ford has announced.
A series of vehicles in addition to the five million recalled last year because of the same problem, a fault in the speed control deactivation system which regulates the maximum speed at which a vehicle can go.
Repeated friction between the brake mechanism and the speed deactivation system heightened the risk of fire to such an extent that Ford has been forced to add pick-up trucks, SUVs and van models to the recall list.
"Following last year's recall, we indicated further analysis would continue to determine what vehicle characteristics were contributing to the potential for switch leakage," explained Ray Nevi, assistant director of the Ford Automotive Safety Office.
"After a year of intensive research, including working with [federal authority] engineers, we have concluded that certain factors on the affected vehicles may lead to the switch overheating."
Ford said it planned on notifying owners of affected vehicles immediately, requesting them to drive their vehicles to specific garages where fresh fused wiring harnesses – the part responsible for the fire risk – would be replaced with the potentially faulty ones.
Today's recall, extending one of the biggest ever recalls in corporate history, comes as bad news for Ford, which endured second quarter losses amid falling orders and higher pensions costs.
Ford's shares fell by 0.51 per cent on the New York Stock Exchange in morning trading today following the announcement of its latest recall.
