POWER TRAIN:AUTOMATIC TRANSMISSION:GEAR POSITION INDICATION (PRNDL)10/06/2022

Ford Motor Company (Ford) is recalling certain 2013-2019 Escape, 2013-2018 C-Max, 2013-2016 Fusion, 2013-2021 Transit Connect, and 2015-2018 Edge vehicles. The bushing that attaches the shifter cable to the transmission may degrade or detach.

Risk: A damaged or missing bushing may prevent the vehicle from shifting into the intended gear, and cause the vehicle to move in an unexpected direction. Additionally, the vehicle may roll after the driver selects the 'Park' position. Either scenario increases the risk of a crash or injury.

Fix: Dealers will replace the under hood shift bushing and add a protective cap over the shift cable bushing, free of charge. Interim owner notification letters, informing owners of the safety risk, were mailed July 1, 2022. Remedy parts are expected to be available in 4th Quarter 2022. Owner notification letters were mailed October 27, 2022. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 22S43.
