    Some 2020-2021 Lincoln Aviator hybrid vehicles may exhibit a brake pedal pulsation or vibration when braking.

    The ABS system appears to be activating without any indicators on the instrument panel. This may be due to the regenerative braking software in the ABS module.

    To correct the condition, perform a coordinated flash on the PCM and ABS module using the latest available software.
