Some 2021 Ford F-150 trucks could unexpectedly shift into neutral while driving. The unexpected loss of engine power could increase the chance of an accident.
In February 2022, an issue was brought to Ford’s Critical Concern Review Group (CCRG) about certain 2021 F-150 vehicles equipped with 3.5L GTDI, 2.7L, and 5.0L engines, along with the 10R80 transmission. These trucks were experiencing an increase in Transmission Fluid Pressure along with a Transmission Fluid Pressure Low Diagnostic Trouble Code (DTC) of P0868. This DTC would falsely activate and cause the transmission to shift into a neutral state while the truck was driven. Once the false activation occurs, the vehicle will coast to a stop and the electronic shifter will attempt to engage Park. Once the vehicle comes to a complete stop, the electronic shifter will automatically shift into Park.
According to the engineering investigation, one of the power-train diagnostic logic software branches was turned on in error when these vehicles were produced. Under certain conditions, this diagnostic logic could inadvertently activate the pump gear failure detection logic even though the hardware is still functioning properly. When this happens, the transmission on-board diagnostics will set the DTC P0868, turn on a Wrench Light telltale, and the vehicle’s transmission will shift into a neutral state. As the vehicle slows to a speed below 2 mph/3kph, the electronic shifter will attempt to engage the Park function and will automatically shift into Park when the vehicle comes to a complete stop. The transmission function can be restored by a key-off/key-on cycle.
Between October 2021 and February 2022 there have been 28 warranty claims and one Customer Contact Center report to Ford that potentially related to this concern.
Dealers will correct the problem by updating the Power-train Control Module (PCM) software. Ford’s number for this recall is 22S15 and the NHTSA campaign number is 22V-188.
