It seems only MY2021 Broncos are affected, but that’s still a substantial batch of vehicles. Ford’s correspondence to owners does not detail how many vehicles are involved but does provide production dates. If your Wrangler rival was built between the dates of September 23, 2020, and September 17, 2021, you may want to visit your local Ford service center.
According to the document, Ford dealerships will, if required, replace the front driveshaft at no cost to the customer – regardless of the vehicle’s mileage. However, Bronco owners shouldn’t delay this repair, as Ford will only replace the part at no charge until October 12, 2023. The repair should take an hour, but customers are asked to allow for more time.
