Ford Motor Co. said it will recall 123,000 older F-150 pickup trucks in the U.S. and Canada to fix a software issue that affects transmission calibration.
The recall covers 2013 Ford F-150s equipped with 5-liter and 6.2-liter gasoline engines. These vehicles were part of an earlier recall. That recall reprogrammed the powertrain control module software. Ford said the software used in the reprogramming is faulty.
The earlier recall was numbered 19S07. The programming did not contain needed updates that prevent a potential unintended downshift into first gear. It also did not have updates necessary to ensure the malfunction indicator light switches if an intermittent transmission output speed sensor signal occurs.
A vehicle without the intended 19S07 calibration remains at risk of an unintended transmission downshift, Ford said. That’s due to intermittent output speed sensor failure. Depending on vehicle speed, an abrupt transmission downshift to first gear without warning could result in loss of vehicle control, increasing the risk of a crash, the company said.
Ford is not aware of any reports of accidents or injuries related to this issue.
Ford built the affected trucks at its Dearborn, Mich., assembly plant and its Kansas City, Mo., assembly plant during most of 2012 and 2013 .
Dealers will reprogram the powertrain control module with the appropriate software calibration. The Ford reference number for this recall is 19S19.
