NHTSA Complaint #11515862 — 2021 FORD F-150

My pickup was at the dealer getting an oil change and tire rotation (23140 miles) and I was informed that the right rear axle bolt had sheared requiring replacement of the axle assembly and that it was not safe for me to drive the vehicle off the lot. This is the second time that the right rear axle bolt has sheared. The first time, the axle assembly was replaced at this same dealer at 14482 miles. I no longer have the original bolt that sheared, I will request the second sheared bolt so it could be inspected if needed. I do not know what the safety ramifications are except to say that both times, Ford said it was not safe for me to drive the truck off the lot. There are numerous reports of rear axle bolts shearing in 2021/2022 F-150s with the Max Tow package (apparently, this package has a different axle configuration) on the Internet. For example: https://www.f150forum.com/f129/2021-powerboost-rear-rotor-axle-bolt-sheared-515460/index21/#post7265683 The vehicle has been inspected (and the axle assembly replaced already once) by my local Ford dealer. It is currently being held by the dealer for the second repair. There were no warning lights, noises or any other indications that the axle bolt had sheared. When the first bolt sheared, I heard a rattle from the right rear tire and I expected to find a broken lug bolt or loose lug nut but instead found the sheared axle bolt. No noises were heard when the second bolt sheared.
