Vehicles Affected: Approximately 184,000 model-year 2011-12 Ford F-150 pickup trucks, model-year 2012 Expedition SUVs and Mustang sports cars, and model-year 2012 Lincoln Navigator SUVs equipped with the 6R80 transmission
The Problem: A problem with the output speed sensor on the vehicle’s transmission lead frame could cause the transmission controls to force a temporary downshift into 1st gear. 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, resulting in loss of vehicle control and increasing the risk of a crash. Ford is aware of three reported accidents and no injuries related to this condition.
The Fix: 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 condition. 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 for free.
What Owners Should Do: The automaker did not immediately announce an owner-notification schedule. Owners can call Ford at 866-436-7332 for more info.
