Official summary
Some 2022 Explorer vehicles equipped with a 3.3L full hybrid electric vehicle (FHEV) engine and built on 12-Jul-2022 and through 31-Oct-2022 may exhibit a coolant leak at the high voltage (HV) battery coolant cooler outlet hose. This may be due to the HV battery coolant cooler outlet hose contacting the bottom pulley of the accessory drive belt tensioner. To correct the condition, follow the Service Procedure to replace the damaged hose and install a cable tie.

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.
