NHTSA Complaint #11696884 — 2021 FORD BRONCO SPORT

I am submitting this letter to report a potentially widespread safety defect in the 2021 Ford Bronco related to the rear differential assembly. Many owners, including myself, have experienced or are concerned about premature failure of the rear differential under normal driving conditions. This issue can lead to loss of vehicle control and represents a significant safety risk on public roads. Ford Motor Company appears aware of the recurring nature of this defect but has not, to date, issued a recall or extended coverage for affected vehicles. I am requesting that NHTSA investigate this issue as a possible design or manufacturing defect that warrants a formal recall or technical action from Ford. Description of Issue: Premature rear differential failure / widespread owner reports Problem has been reported to Ford Motor Company as well as Sutton Ford Dealership. They did the inspection and diagnosed it. I took my vehicle to that dealership numerous times and told them about the noise I was experiencing and it came back no problems found. This truck has had several recalls and problems since it rolled off the assembly line.
