2021 Ford F-150 Hybrid

Rear Rotor/Axle Bolt Sheared. Truck not drivable. Dealers in area can't look at truck for at least a month and saying shouldn't drive it either. They won't order parts unless I tow truck to them. I'm having the same issue as posted in these threads and various FB posts too. https://www.f150forum.com/f129/2021-powerboost-rear-rotor-axle-bolt-sheared-515460/ & https://www.f150gen14.com/forum/threads/f150-powerboost-axle-bolt-sheared-off.10392/

The bolt that holds the left side rear wheel to the axle sheered off. This was discovered when the vehicle had 9,200 miles on it. When the wheel was removed the sheered bolt and washer fell out. Based on the condition of the bolt it was apparent that the bolt had been sheered off for quite some time. This truck has not been off road nor has it been used to pull a trailer yet. The truck is a 2021 Ford F150 Powerboost truck Platinum edition.

I heard a very loud screeching noise around 4K miles and took it to the dealership, they said my axle nut on the driver side of the truck was sheared off. They said it was covered under warranty and repaired the issue. 8k miles after repair it is doing the exact same thing. No check engine lights for this issue ever appeared on the dash. Ford spend about 3 weeks or longer fixing this the first time. They promised when I purchased the truck if there where any issues I would get a loaner vehicle, nothing available to loan on the first time. Now that it’s happened again I called to scheduled a time to repair and they say I can’t even get seen until January 20th. So this truck has costed me a lot of out of pocket money for rentals.

The contact owns a 2021 Ford F-150. The contact stated while driving 65 MPH with the cruise control activated, the vehicle made a hard-left turn while attempting to merge into the left lane. The contact stated that a message to assume control of the vehicle was displayed and the navigation system independently deactivated. The contact aggressively turned the steering wheel to remain the lane he was driving in. The vehicle was taken to the dealer and a software update was performed; however, the failure persisted. The manufacturer was contacted and advised the contact to reach out to the dealer for assistance. The contact stated that a case was filed. The failure mileage was unknown.

ON 10/22/2022 I TOOK MY TRUCK IN TO THE FORD DEALERSHIP FOR OIL CHANGE AND TIRE ROTATION, UPON ROTATING THE TIRES THE TECHNICIAN FOUND THE AXLE BOLT ON THE REAR DRIVERS SIDE WAS SHEARED OFF AND PART OF THE BOLT WAS STILL IN THE AXLE. THE DEALERSHIP KEPT MY TRUCK AND ORDERED A NEW BOLT AND GAVE ME A VEHICLE TO DRIVE. MY TRUCK HAS 26,744 MILES ON IT. I AM CONCERNED AFTER READING MANY POSTS ON FORD FORUM THIS WILL CONTINUE TO HAPPEN AFTER WARRANTY EXPIRES. SOME OF THE POSTS STATED FORD DEALERSHIPS WERE REPLACING THE AXLES. PLEASE ADVISE THANK YOU

I took my 2021 F150 Powerboost with Max Tow package into the Ford dealership for service and to inspect a noise coming from the driverside rear wheel. When the wheel was removed the source of the noise was confirmed as a sheered-off axle retaining bolt. I was told by the service department the truck was unsafe to drive. I am unsure if this nut holds on the wheel hub assembly but I'm guessing it could lead to loss of power in the affected drivewheel or loss of the wheel altogether. Upon doing some internet research this is quite a common issue with the 3/4" floating axle that was new to the 2021 model year for the Max Tow package. This is an issue with the drivetrain of the vehicle that could lead to safety issues for the occupants and others and should be recalled with upgraded/redesigned parts.
