2021 FORD F-150 HYBRID Wheels Problems

The rear wheels are locking up at acceleration after stopping.

The contact owns a 2021 Ford F-150. The contact stated while driving approximately 65-70 MPH, the contact was flagged down by a nearby driver and advised to pull the vehicle over to the shoulder of the road. The contact stated that the vehicle was driven to the shoulder of the road. The contact exited the vehicle and proceeded to inspect the vehicle. The contact noticed that the rear driver's side rim cap had detached. The contact stated that the center axle bolt was still attached to the rim cap. The vehicle was towed to the dealer where it was diagnosed with a failed rear axle half shaft and hub and the rear axle half shaft and hub needed to be replaced. The vehicle was repaired. The contact stated that the driver's side rear axle bolt had previously been replaced and was under an unknown recall. In addition, the contact stated that the failure had occurred on five occasions within two years and that the vehicle was unsafe to be driven. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 20,000.

Mileage: 20,000

On November 29, 2023 I took my 2021 F150 to Larry Miller Ford for servicing and repairs related to Recalls 22S71 and 23S35. When the tech was rotating the wheels he discovered that the axle shaft bolts were sheered off on both the left and right rear wheels. The service manager called to tell me that this was a serious safety issue and that only the brake rotors were preventing the wheels from falling off the truck. The service manager told me there was a "Customer Satisfaction Program 22B34" issued by Ford, but no Ford Recall relating to the problem. Larry Miller Ford has replaced both axles and axle bolts. I am waiting to find out if there is damage to the rotors, calipers or brake pads, a concern since the sheered off bolts were rattling around within that area since breaking off apparently between service visits. I strongly believe Ford should be required to issue a recall on this problem. I never received a notification on CSP 22B34. Had it not been for my tire rotation, the wheels could have fallen off at highway speed.

My truck has the Maximun payload axle upgrade. The axle bolts on the end of the shaft have broken. I first notice squealing sound of metal from rear of truck. I searched on line for the symptom and found the problem. I then removed passenger rear wheel to verify broken bolt. I took my truck for service to Morries Grand Ledge Ford in Michigan. They verified the problem, told me it was not safe to drive and have ordered parts. They also informed me that the defective axle is not covered by recall on my vehicle. The service representative did confirm that there are recalls for the same axle but not my vehicle.

The Axle bolts on both sides of the truck sheared off. The passenger rear axle bolt sheared at 15,000 miles into having the new truck. The driver side rear axle bolt sheared at 21,000 miles. This is a large safety concern and is not unique to just me. The first axle bolt sheared and was repaired once I figured out the problem at a Ford dealer. The second bolt is currently being repaired in the same dealer's service department. There was no warning or detection of this problem other than a rattling sound during acceleration and a wizzing sound during braking. I do not have either of the sheared axle bolts. They were kept by the dealer.

The driver's side rear axle bolt sheared off over the course of normal driving. Ford is aware of this problem, advises to not use/drive the vehicle, yet no recall has been issued. Without a recall, getting this issue fixed will take weeks/months and Ford should pay for a rental vehicle since this is clearly a manufacturing defect.

Rear axle bolt broke off

Bolt that holds the axle on to the vehicle is broken in half and therefore the axle can unexpectedly fall off the vehicle. It is the rear driver side axle. This was noticed when I recently replaced my tires and the broken screw was loose in the wheel.

Planned one week, 1,400 miles roadtrip along pacific coast during memorial day weekend. Before starting our trip I went to rotate the tires and upon removing the rear passenger side wheel a bolt and metal gasket fell out. Issue: Center bolt that locks the brake assembly to the rear axle shaft was sheared off with remaining half stuck in the axle shaft. How was your safety or the safety of others put at risk?: The truck would have been loaded for our week long roadtrip up North. On the way back we were going to tow our 5000lbs trailer. This bolt would have impacted the braking ability, cause damage to the rear axle assembly possibly resulting in an accident. If I didn't rotate the tires before leaving who knows what could have happened especially if I was towing. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Vehicle is currently at a Ford dealer for axle shaft replacement. The service manager had a broken bolt from another vehicle and asked me is this what happened? There are hundreds of F150 owners complaining about the same thing on various forums. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet. I'm glad it didn't get to that point. But from all users that had this problem and got replacement axle for what seems like defective bolts I would hope Ford would voluntarily inspect and issue a recall. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No fault lights but I did hear faint grinding sound when the windows are rolled down. I guess the bolt was spinning around in the wheel.

The service bulletin needs to be a recall. The Program number is 22B34 where on all max tow packages the rear axle bolt breaks off. It is very common and need to be addressed and not just a satisfaction program. It happened to my truck at 27,000 miles.

Noise coming from driver's side wheel. Removed the wheel and the axle bolt and washer fell out. The bolt had broken completely off. https://www.f150forum.com/f129/2021-powerboost-rear-rotor-axle-bolt-sheared-515460/index107/

Ford F-150 CSP 22B34 Rear R/H axle hub bolt sheared off.

rear passenger side axle bolt sheered off.

Passenger side rear axle bolt failure. The bolt sheared off completely and was found rattling inside the center cap. Dealer states vehicle cannot be driven. Ford will provide rental until repaired but can’t provide estimated repair date.

Bolt that holds the rear passenger side axle in place has broken off. This was found during a tire rotation at the dealership.

BROKEN AXLE BOLT

Passenger side, rear wheel axle blot sheered off, been loose for ??? Was told not to drive the vehicle, safety issue. Seems to be a common problem with the Mac towing package.

Heard squealing in brakes and rattling in passenger rear area. Took to Ford service and they found loose bolt head and washer that was sheared. Recommended not to drive vehicle but could not confirm that it is a warranty issue at this time. Less than 24k miles on vehicle.

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.

The bolt that holds the wheel hub on the rear axel sheered off on both sides of the vehicle. This occurred on two different occasions about 3 months apart.

I took my truck in for it's first oil change and tire rotation. I was called by the dealer a few hours later and told that when they pulled my rear tire off, the rear rotor axle bolt was seared and the vehicle is unsafe to drive. As the tire had never been removed previously they said it had to come from the factory that way, and that I was lucky the tire did not fall off while driving the truck. I was told the parts would be ordered and repairs done under warranty but it's been over a week with no information or results. I researched the internet and found hundreds of owners experiencing the same issue with the rear axle bolt being seared, apparently at the factory. If this makes the vehicle unsafe for the road and it's obviously affecting 100's of vehicles that I can find in some internet search, the problem is likely much worse. I have the exact issue reported in this forum at https://www.f150forum.com/f129/2021-powerboost-rear-rotor-axle-bolt-sheared-515460/.

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.

Rear axle bolt sheared off. Per Ford axle must be replaced

Rear passenger axle bolt sheared off.

The wheel hub axle bolt sheared off under normal conditions-dealer was unaware this was even an issue and told me the bolt they found within my wheel assembly and its attached washer was picked up off of the road (road debris) that they removed it and it would not grind anymore. I did basic research as an uninformed consumer and within seconds learned this is an issue on hundreds of other power boost pickup trucks. There is extensive documentation online regarding this issue. I called my dealer who has yet to respond to me. This is a major safety issue-the only thing holding the wheel on is the brake caliper. With as many documented cases as I can easily see online-the fact that my dealer is not aware of this indicates Ford has done nothing about it. This should be a recall. Please advise.

Left rear axle bolt sheared off into the wheel spontaneously. It is available for inspection. . Currently at dealer right now for repair. Dealer indicates vehicle not safe to drive due to potential for loss of wheel, brake components and wheel hub/axle during travel. I have not experienced loss of a wheel while driving luckily. There were no warning lamps/messages etc. No symptoms of the problem prior to failure were noted. The only sign of an issue was loud squealing from the left rear wheel when brakes were applied or when turning the steering wheel slightly either right or left. Refer to the following for additional cases. https://www.f150forum.com/f129/2021-powerboost-rear-rotor-axle-bolt-sheared. No TSBs have been issued on this based on database search.
