Official summary
This article supersedes TSB 23-2213 to revise Figure 1, add 2024 vehicles and the part list. Some 2021-2024 Bronco vehicles may exhibit a whistle noise below the lower left windshield area at the bottom of the A-pillar. This may be due to a missed body sealer application at the factory.
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.
