2021 Ford F-150 Hybrid

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.

When I come to a stop, my truck will try to lunge/jump forward after a few seconds. It has been happening for a few weeks now. This could result hitting another car in front of me or potentially a pedestrian if I am stopped at a cross walk. I took it a dealer yesterday and they confirmed the problem. They attempted to reprogram it and said it fixed it. Later that night and again this morning, it did it again.

The rear axle bolts sheared off for unknown reasons. The symptom was a metallic rattling noise from the back of the vehicle - the noise was pieces of the axle bolts bouncing around inside the wheel center cap. The bolt in questions holds the rear axles in place. Vehicle has been at dealership for 2 weeks as they said it was a common problem that is a safety issue. Said it was possible for one or both of the rear wheels to fall off if I had continued driving it. Obviously losing one or two wheels is a huge safety concern. My dealer said he has seen this exact issue 4-5 times on similar trucks. Vehicle is less than 9 months old and has less than 13,000 miles on it. Vehicle is being repaired under warranty but using the same parts.

A noise being heard any the rear-end of the truck. Upon taking the rear tire off for investigation a bolt head was noticed in the center of the rim. This bolt came from the axle. The bolt in question holds the axle in place, if driven for a great distance then a chance of the axle floating towards the gear which could have caused a major safety concern for the occupants of the truck and anyone on the road Truck is currently at the shop, but dealer is replacing parts with same components. No root cause has been found to address concern. Other side of axle could reflect the same condition

I brought my truck in for routine maintenance oil change & tire rotation and was notified by the dealership that the right rear axle bolt was broken off and that the axle needed to be replaced and that it wasn’t safe to drive it until it was replaced well here’s my problem I didn’t know it was broken or unsafe to drive and had I not brought it in for the oil change early I would still be driving it like that this is a serious problem which could result in a loss of control and accident I’m not the only one that has had this happen I’ve researched it a little and found multiple people on an F150 forum that have had the same experience

There is a fairly common issue where there are bolts at the end of the rear axles (P/N 19S426) have the bolt head shearing off and rattling around inside the wheel. I had one such broken bolt. The issue is large enough that hundreds of owners are reporting this on Ford Truck forums, namely on the 2021 Ford F-150 Powerboost with the Max Tow Package like mine. Ford needs to recall this.
