Dealer said ford advised them that the truck must sit till the axle is replaced due to it being a safety hazard to drive. My truck is now sitting at dealer waiting for a replacement axle.

13800 miles, broken axle/wheel bearing retaining bolt. Screeching noise. Bad wheel bearing. Dealer will not replace wheel bearing because they do not correlate the broken bolt to a bad wheel bearing. Leaving me with a bad wheel bearing that I consider prematurely worn out and is making a clicking sound. Dealer says they cannot replicate the noise so will not investigate further

Myself and several other individuals with 2021/2022 Powerboost F-150s are experiencing an issue where the whole vehicle will lurch forward as if hit from behind after coming to a stop. This can result in the truck hitting the vehicle in front of you if you are in tight traffic.

In May 2022, the passenger side right rear axle bolt sheared off creating a squealing/grinding noise from that wheel. The only thing holding the wheel onto the axle were the brake caliper bolts. The repair involved a new axle. In early Sept 2022, the driver side rear axle bolt sheared off with the same results. The vehicle is now in the shop waiting for the parts to arrive. Dealer advised that this is a serious safety issue and requested that the vehicle be towed to the service center.

Driving the truck the transmission shifts down hard depends on the day it-??s hard trying too get used to braking when it downshifts like it does. Then when leaving and up shifting sometimes it wants to jerk the truck and hesitates. My father owns a 2019 and his transmission is amazing. Mine is horrible. Since I bought the truck it-??s been like this and I just don-??t want to be stuck with a broke transmission when my warranty expires one day for it. The speed it jerks when it-??s low speed like taking off, the down shifting is going from like 50 down. This happens all the time. I just see people with my year truck getting new transmission because their transmission already is no good.

Upon getting into the vehicle, it was noticed that there was gear oil leaking all over the rear passenger wheel prompting me to remove the wheel cap. Inside, the axle nut that connects to the axle shaft was completely sheared off and not connected. I am not sure how long it was like this, but from my experience without this nut the axle could have slid into the differential causing a rear axle failure, if that were at highway speeds, or in descent while pulling a trailer that could have been very serious. The broken parts are with the vehicle at the servicing dealership Currently the vehicle is at the dealer being repaired. Due to part shortages and as noted by the dealer being unsafe to drive I will be without a vehicle for 3-4 weeks possibly. The problem has been reproduced by multiple other truck owners noted online in group forums etc., and the dealership was well aware of the issue noting there were 3 other similar trucks in for the same repair needed. There has been no inspection by they manufacturer, only by the dealership where purchased and servicing the vehicle. No noticeable issues right before the problem occurred. Approximately 4000 miles prior to the issue it was noted that the same wheel seemed to be locking and stuttering while turning. Almost as if the brakes/axle were locking right when taking the vehicle in for routine service. It was noted to the dealership, but being that only light service mechanics were on duty they could not do a full inspection. They did inspect brakes for locking etc. found no issues and the locking / stuttering was no longer noticeable.

Right real axle bolt is sheared. This appears to be a big issue with 2021 Ford F150's with the max tow option with the 3.5 ecoboost. Parts back ordered for over a month. Dealer will not release the truck due to safety issues and unsafe to drive.

The driver side rear axle retaining bolt sheared off rendering the truck not drivable. The truck is at the Ford dealership I purchased it from waiting for a replacement part. This is such a common problem that the axle shaft is on back order, so I am without my truck until the parts are available. Upon researching online I have found this to be a common problem that Ford is very much aware of but have not taken action to correct.

Drivers side rear axle bolt sheared off. Noticed noise coming from rear while driving, removed wheel, bolt head and washer fell to the ground. Bolt head and washer we-??re both retained. Local dealerships (albuquerque, NM) do not have the capacity to diagnose the truck for a minimum of two weeks. The structural integrity of the axle and drivetrain are in question.

Broken retaining bolt holding the wheel on the right rear axle. Dealer said too dangerous to drive so they replaced axle. Dealer has old axle and broken bolt. This problem exists in the 2021 F150 Powerboost truck with 9.75 in 3/4 floating axle. Several postings on F150 forum of this happening to others with same truck. Nothing holding rear wheel on except brake caliper if bolt brakes and wheel wobbles loose. When service tech takes wheel off to rotate tires the broken bolt falls on the floor.

Rear passenger axle bolt sheared off.

When drive train goes into electric drive mode, the vehicle will jump/lurch/bang after stopping like I was hit by another car pretty hard. This will only happen when the engine either goes into hybrid electric mode or engine turns off after a stop in sport and other modes. It will not happen in tow mode where the engine stays on. The issue is the aux pump on the transmission going bad, this was found by dealer and part is on national backorder. Truck can jump a foot forward at red light if foot is not smashing the brake pedal down - seems to be an issue popping up daily on forums from others having issues.

Truck does not always does not always downshift to a lower gear at a stop and instead remains in 8th gear. This poses a safety risk do to a lack of acceleration and also causes an unanticipated sudden jerk when it does finally does engage in a lower gear.

Drive shaft on 21 F150 broke in half while driving on 07/01/2022. I was traveling at 35+ MPH. This could have been much worse at a higher speed. Truck has been to local dealer (Mac Haik) for service twice in last few months, they never mentioned the recall. Dealer contributed to failure by not evaluating issue for over 20,000 miles.

I took the vehicle in for a tire rotation and oil change at approximately 18,000 miles. The dealer informed me that the passenger side rear axle bolt had sheared off and that the bolt had to be drilled out and replaced. The repair did not solve the problem and now the axle has to be replaced.
