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(s) on the rear window that is too narrow. Do not replace the rear quarter windows. To correct this condition, follow the Service Procedure to secure the rear quarter window(s) in place until a new rear window can be obtained to permanently correct this condition.
