Ford is issuing a safety recall for 2011-2012 Ford F-150s for a potential issue with the output speed sensor on the vehicle’s transmission lead frame. Under certain conditions, Ford says the transmission controls could force a temporary downshift into first gear.
Around 202,000 vehicles are effected by the transmission recall, including the 2012 Ford Expedition, Ford Mustang and Lincoln Navigator.
“Depending on the speed of the vehicle at the time of the downshift, the driver could experience an abrupt speed reduction that could cause the rear tires to slide or lock up,” the recall notice says, adding the condition could result in loss of vehicle control, increasing the risk of a crash.
Ford is aware of three reports of accidents and no injuries related to this condition.
Affected vehicles are equipped with a 6R80 transmission and include certain 2011-2012 Ford F-150 vehicles built at Dearborn Assembly Plant and Kansas City Assembly Plant, Aug. 19, 2011 through March 9, 2012.
Dealers will inspect the powertrain control module for diagnostic trouble codes tied to the issue. If no related diagnostic trouble codes are present, dealers will update the powertrain control module software, which will eliminate the downshift into first gear if an OSS fault occurs. Additionally, as part of the corresponding customer satisfaction program, Ford will provide a one-time replacement of the lead frame at no charge within 10 years or 150,000 miles from the warranty start date.
If related diagnostic trouble codes are present, dealers will update the powertrain control module software and replace the lead frame at no cost to the customer.
Also affected in the recall are 2012 Ford Expedition vehicles built at Kentucky Truck Plant, Aug. 19, 2011 through Dec. 19, 2011; Ford Mustang vehicles built at Flat Rock Assembly Plant, Aug. 19, 2011 through Feb. 21, 2012; and Lincoln Navigator vehicles built at Kentucky Truck Plant, Aug. 19, 2011 through Dec. 17, 2011.
