Our brand new 2023 Ford Bronco Sport was destroyed by a spontaneous under-the-hood fire that occurred within thirty days of delivery and with less than 50 miles on the odometer. An independent examination found this consistent with a fuel injector fire. Ford Motor Company has publicly acknowledged similar problems with the Bronco Sport models and purportedly has recalled and "fixed" all effected vehicles. We notified Ford of this incident, that the production and delivery dates of our Bronco Sport were well AFTER these recalls had been completed, and that the VIN of our Bronco Sport does NOT appear on Ford's recall registry. In the overwhelming interest of public safety, we have urged Ford Motor Company to recover this vehicle and conduct its own investigation. …
