Some 2013-2014 Ford Flex vehicles equipped with a power liftgate and built on or before 9/9/2013 may exhibit a condition where the liftgate power open and/or close function is inoperative, or a crunching noise from the liftgate motor is heard during operation. DTC B2908 may be stored in the LTM (liftgate/trunk module).
If the liftgate power open and/or close function is inoperative or a crunching noise is heard from the liftgare motor, replace the liftgate motor (refer to workshop manual section 501-03). Perform a general procedure for liftgate adjustment, and reprogram the LTM to the latest calibration using IDS release 87.01 or higher.
The replacement liftgate power motor is available as P/N DA8Z-14B351-A.
