2021 FORD F-350 SD Complaints

The contact owns a 2021 Ford F-350. The contact stated that while driving at an undisclosed speed, the steering wheel was vibrating. There were no warning lights illuminated. The vehicle was taken to an independent mechanic who informed the contact that the failure was due to the driveshaft. The vehicle was taken to the local dealer who informed the contact that there needs to be weight in the truck. The contact attached a trailer to the vehicle however, the failure still occurred. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 89.

This truck on a daily basis, shuts down with out warning. Check engine light comes on some time, some times get P0191, P0171 and other codes dealing with fuel rail and pressure. Vehicle had less than 10000 miles when started. Dealer don't know what to do. Shuts off when you are in a turn and leaves you with out steering, and shuts off when coming to a stop sign, or trying to park. Fuel filters have been changed 2 times in 2 months. Truck is not safe to drive because it keeps surging and cutting off. Idle speed varies as much as 250 rpm when sitting still. Now

When my F-350 had only 2,265 miles on it, I was getting in my truck and closed the door. When it closed, the rear window shattered. There was no object that had been thrown at or through the window(no lawn service around that day, etc.). I immediately called the local Ford dealership(Landers Ford in Collierville, TN) and was told that the window would not be covered under warranty. I then called the Ford customer service # on the ford.com website and they stated that this was not a quality issue and that it would not be covered under warranty. It is clear by looking at the picture that the window shattered out as though the pressure in the truck when the door closed caused the break. This occurred on 9/10/21 and I took the truck to Safelite on 9/13/21 to have the window replaced at my own expense.

An unknown electrical issue possibly sensor, module or wiring related causes several faults in the system and they appear on the dash. These faults disable many safety features built in to the vehicle and a few convenience features as well. The faults displayed are: "pre-collision assist not available", "hill start assist warning", "service advance trac" and "drive mode not available" When this happens randomly the vehicle will stop producing forward acceleration and slow down very quickly as if I took my foot off the accelerator. When this occurs it is a dangerous situation made worse at higher speeds and I must quickly move off the road without causing an accident. The vehicle has been to the dealer 4 times since new (4765 current miles) and there is no definite solution at this time.

The contact owns a 2021 Ford F-350. The contact stated while driving 72 MPH, the contact heard an abnormal sound coming from the vehicle. The contact pulled over and upon inspection of the vehicle discovered that the sliding glass on the panoramic sunroof had shattered without incident. As the contact continued driving, the contact could hear the headliner shaking as the glass began flying off the vehicle due to the failure. The contact was forced to pull off the road again and clear all the shattered glass pieces from the top of the vehicle. The contact then took the vehicle to a dealer where he was informed that they would perform an inspection of the vehicle to determine the failure. A week later, the contact was informed by the dealer that the manufacturer had denied repair of the vehicle and that the failure was not a mechanical defect. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was 6,237. The VIN was not available.

Tailgate has randomly opened twice. Tailgate function on the remote was definitely not being pressed.

Electronic tailgate on the 2021 Ford F-350 is opening on its own while driving. Doesn't matter the speed...its happened at 10 mph and at 60 mph. This is a critical issue since it is damaging RVs. My latest occurrence is noted in the Additional Details section, but it has now happened three (3) times since I purchased brand new with 6 miles on it...now has about 10,900 miles. There was a recall on model years 2019 and prior for this very symptom caused by moisture getting into the wiring harness.

I was recently informed by Ford that my vehicle is subject to a recall (21S31) because the rear axle may deform and detach from the vehicle. I believe the Ford Safety Recall Report (and NHTSA Recall Number) is 21V-536. My concern is related to the proposed remedy. Ford States that additional welds will be applied to the axle. Based on the information provided, I believe this will only mask the symptoms of a failure (detachment of the axle), and not the problem itself (crushing of the axle tubes due to insufficient tube wall thickness). I am a licensed professional engineer, which is to say that I have a basic understanding of material behaviour. With this in mind, I would respectfully ask you to consider the following: 1) Primary: Outright replacement of the defect axle housing with a unit that is manufactured with the "old design" axle tubes. If item 1 above is not chosen, I propose the following alternatives (in combination): A) Requiring replacement of the axle housing if paint loss is observed at the locations where the u-bolts are used to strap the axle to the spring perches. Many people have observed paint loss at this location, and it would indicate deformation of the tubing. B) Warrantying the axle housing for an extended period of time - perhaps 8 years or 100000 miles as was done by Toyota due to the frame defects which affected their pickups. C) Certification by a licensed professional engineer that the proposed remedy (welding the axle) will prevent deformation under rated conditions. I believe this is important because it will require a "person" to certify the adequacy of the repair. My intent in suggesting this is to ensure that the defect is not left in place. Again, the proposed remedy seems only to "mask" the problem. I fear it could result in another "Firestone Situation", where the public is put at unnecessary risk. I greatly appreciate you considering this request.

My setup: truck is level, trailer is 3/8" drop in front, and hitch ball up leaving one hole open from top. After installing product, ensuring proper setup, there is concern for towing safety, as the bottom of the drawbar drop is ~8-1/2" from ground, with reports from others that this setup has on numerous occasions, caused the drop portion of bar to contact pavement under normal towing conditions across the U.S. This has caused concern for possible catastrophic failure of drawbar drop when towing, believing that the welds on drawbar could become weakened and result in a disconnect of tow vehicle and trailer. I contacted the company, asking if they had plans to offer a 0" (would be an actual 3" length drop per their specs on the 6" and 8" drops) drop, or if they could say how much of the excess could be removed/cut from the drop safely. Their response is that there are no current plans to offer other drops and modifying the drawbar would void warranty. Others on various social media have warned of the drop making contact with pavement during the likes of National and State park entries/exits, as well as intersection transitions, etc.. I continued with my order/install, believing they had possibly installed incorrectly, but now see the concern, and do not want to void warranty, and in turn do not want to have a catastrophic failure that could kill someone..
