Service bulletin TSB 24-2127

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

This article supersedes TSB 23-2298 to update the production fix date and parts list. Some 2021-2024 Bronco Sport vehicles equipped with a 1.5L engine built on 24-Jul-2021 and through 14-Dec-2023 may exhibit a hissing noise from rear liftgate area when driving straight between 35-50 mph (5680 km/h). This may be due to the absence of the rear floor insulator located in the spare tire compartment. To correct this condition, follow the Service Procedure to install a rear floor insulator in the spare tire compartment.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
