Official summary
Some 2021-2023 Bronco vehicles equipped with a soft top roof may exhibit rear quarter window(s) that do not stay attached to the rear window after driving the vehicle or using the soft top quick access cargo function to raise the rear of the soft top assembly for luggage compartment access. This may be due to a retention channel on the rear window that is too narrow. To correct this condition, replace the rear window assembly (service base part # 7842006). Refer to Section 501-18A > Removal and Installation > Soft Top Assembly.
Vehicles covered
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.
