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

Some 2021\-2024 Bronco vehicles may experience a repeat loss of window initialization which results in a loss of short drop and/or one\-touch up and one\-touch down feature operation. This may be due to a recent short drop enhancement that is contained in the driver door module \(DDM\) and passenger door module \(PDM\) software. To correct this condition, update the DDM and PDM to the latest software levels then download and run the Loss Of Power Window Initialization Concern application using Ford Diagnosis and Repair System \(FDRS\). When prompted by the application for a password, use DSPWR\-308. If the vehicles DDM and PDM had software part numbers ending with CN or CR when it arrived, advise the customer that the vehicle will no longer exhibit a short drop event to all door windows anytime the vehicle is unlocked using the remote keyless entry \(RKE\), accessory keyless entry keypad, or the interior door unlock switch.
