Official summary
Some 2020-2023 Escape and 2021-2023 Bronco Sport vehicles may exhibit a moan noise when the vehicle is driven in reverse (R) in cold weather and/or high humidity. This may be due to the suspension sensitivity of the vehicle. To correct this condition, follow the Service Procedure to replace the standard and reinforced rear caliper bushings and apply Kluberpaste to the machined surfaces of the brake caliper and caliper support bracket.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
