Some 2020 Explorer PHEV vehicles built on or before 13-Dec-2019 may exhibit a hard brake pedal or reduced pedal travel when the transmission is initially placed in gear with no diagnostic trouble codes (DTCs) stored in the anti-lock brake system (ABS) module. This condition only occurs at initial vehicle start-up and will no longer be present after the brake pedal is released and re-applied during the same key cycle. This is not a lack of power brake assist. This may be caused by the software in the ABS module. To correct the condition, reprogram the ABS module using the latest software level of the appropriate Ford tool. Pls procced as the normal warranty procedure
