Some 2023 Bronco 3-door vehicles built on 01-Jul-2023 and through 25-Jul-2023 may encounter a whistle noise from the right side A-pillar area. Inspect the window run at the sail area (triangle) for any type of deformities and/or not sitting flush. This may be due to the inner belt moulding being too long and deforming the sail moulding, compare to the driver side if necessary.
