Jun 11, 2026SteeringLane Departure

The EPAS (Electric Power Assisted Steering) module experienced an internal sensor failure, causing a sudden and complete loss of power steering assist. The vehicle is available for inspection upon request and the EPAS module has been retained. The loss of power steering occurred without warning while the vehicle was in motion, requiring significantly greater physical force to maintain control of the steering wheel. This creates a serious risk of losing vehicle control, particularly at higher speeds, during lane changes, or in emergency maneuver situations. Because the failure occurs randomly and without any prior indication, there is no opportunity to safely prepare or pull over before it happens, putting both the driver and other motorists at risk. Yes. The issue has been acknowledged by multiple Ford dealerships and independent mechanics, all of whom confirmed this is a known and recurring problem with this vehicle’s EPAS system. Numerous online automotive forums also document other owners experiencing the identical failure, suggesting this is a widespread issue rather than an isolated incident. The vehicle was inspected by an authorized Ford dealership, which confirmed the EPAS module failure and acknowledged familiarity with the issue. No warning lights, dashboard messages, unusual sounds, or handling changes occurred before the failure. The power steering loss happened suddenly and without any prior symptoms, leaving no opportunity to anticipate or react to the malfunction before it occurred.

After a day of heavy rain, the vehicle stalled at a stop light and would not restart. The steering wheel and transmission locked, preventing the vehicle from being placed in neutral, creating a safety hazard as the vehicle was immobile in traffic. No warning lamps appeared prior to the failure. The vehicle required a tow. The dealer confirmed water had intruded through the passenger side cowl/firewall seam due to inadequate factory sealing, tracking down and pooling directly onto the Body Control Module (BCM) mounted on the passenger side firewall. The BCM failed due to water damage, causing PATS desynchronization and the no-start condition. The BCM failure subsequently shorted out the starter motor. Dealer replaced the BCM, repaired the leak, and replaced the starter. Total repair cost approximately $3,200. Failed components are available for inspection at the dealership. This identical failure; passenger side cowl water intrusion leading directly to BCM damage — is documented across numerous 2021+ F-150 owner forums, indicating a widespread factory sealing defect at the cowl/firewall/inner fender seam junction.

September 2025, we were on a vacation when we noticed that the column gear shifter on our 2021 Ford F150 seemed a bit "loose" when shifting. No issues getting into the appropriate gear…but a weird loose feeling. My husband pulled off the leather boot on the column (not sure if this is what it is called, I believe it keeps dust out) and found the problem. Two missing bolts! Earlier that year, I had found a bolt in the floor of the truck, and, unable to find where it came from (or did it even belong to the truck? I did not know) I put it in a ziploc bag, into the glove box. Turns out that bolt fit. So we had one bolt, and the shifting felt okay. But we still needed one bolt, so I did some internet sleuthing. I found the part (W790628S900) and ordered it, and we installed it when we got home. We theorize that the “ziploc bolt” came loose early in 2025, and the second bolt (never found) came loose on our trip. We know that up until this problem, we had never, ever, removed that dust cover, so we were not responsible for the two bolts coming loose. Components: that "failed" would be the two bolts on the column gear shifter (under the dust cover) Safety: we were very worried that without the two bolts, we would not be able to shift at some point! Confirmed: no, because we were camping on vacation, and did the troubleshooting ourselves Inspected: we will ask our mechanic when we next take the truck in Warning: no, just that we noticed that the column gear shifter was "loose" (again, likely that this was after the 2nd bolt came out).

At a stop light vehicle will turn off and nothing electrical will work. It will have to be restarted, While turning at low speeds the electronic steering completely stops working and almost hit another car. All electrical power failure until modules reset then will start. This all happens randomly so it could happen at any point and cause serious injury. Ford can't seem to find a repair for the intermittent issue.

The steering had a failure while driving on the highway. Driving straight, not making any turns, and a steering error came across the dash for the failure. Complete loss of steering functions. THis happened at 58000 miles. The problem is now occuring daily and is thought to be the power steering module. All steering control is lost.

The spark plugs were replaced, and the vehicle was repaired. The contact stated that on a separate occasion, a month after the repair, there was an abnormal sound coming from the steering wheel. The vehicle was taken back to the dealer, where it was diagnosed that the wheel bearing and axle had failed and needed to be replaced. The vehicle remained at the dealer unrepaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 56,000.

Power steering rack failure, while driving though a puddle less than 6 inches deep. Cost over $1900 to replace. My wife's 2014 volkswagen passat is able to drive though deeper water.. on 8/13 I was unable to move over on a road that had some puddles due to oncoming traffic. After driving though the small puddle my power steering went out. Took to the mechanic and he said its a known issue due to how Ford did not seal their wiring well under the trucks and it hangs lower allowing the water to seep into the cables and cause the powering steering rack to fail.. this is unacceptable its a truck a puddle should not cause a truck to loose power steering.

When driving across railroad tracks, or at lower speeds primarily when turning sharp or into parking spaces, a power steering assist fault light flashes and steering becomes difficult unless truck is moving. The only remedy that I know is to put the truck in park, turn off, and restart. This corrects the issue until the criteria mentioned above is met and then it happens again, and again...... The vehicle has been taken to a repair shop where they recommended a new rack and pinion. They mentioned this is a very common issue with ford vehicles. This vehicle has 34k miles and has been well maintained. I'm very disappointed that it consistently has this issue and worry about the loss of steering at a higher rate of speed.

When starting the vehicle a message displayed stating "Power Steering Fault Service Required". I was able to shut off the vehicle and restart with no issue. Currently, restarting the vehicle no longer has any affect and the power steering is out completely. An appointment has been scheduled with Ford in two weeks. Unfortunately, this is my only means of transportation. I was at work when the power steering went out completely and had to drive home. On my drive home, the traction control tripped jerking the wheel and it felt like the whole vehicle jumped.

The power steering assist model failed rendering the truck without power steering. I called my dealership and they told me that the part is not available until sometime after February but could not give new a more precise date. I called Ford customer service on [XXX] and they could not give me an availability date on the part (Ford customer service case # [XXX]). They also informed me that the part is not under recall. This leaves me with an truck that is basically safe to drive for the last 60 days. I am the ogival owner of the truck and it has only 5300 miles on it.

The ford is a ford F150 2021 with only 47,000 miles on it. It is a well taken care of truck with all routine maintenance done. The power control steering module has completely gone out in my truck. Unfortunately this problem began to occur with my children in the car when a warning light came on and then the power steering completely went out making it extremely difficult to turn and steer the car. Thankfully this occurred on a backroad and not the highway. Needless to say, it is not safe to drive my car and is now sitting in the shop. Ford has confirmed the problem but is unable to get a new PSCM because it is back ordered meaning many people are facing the same issue. We are told they are unsure if the part will become available in a month or 6 months which means we are out a car for that long. With the part being on such a back order, I would hope this would be a red flag to not only ford but to the NHTSA that this is a common problem and error on a faulty part which is extremely dangerous.

The steering wheel would not turn. Similar to when cars did not have power steering but much worse. Had the truck taken to the Ford Dealership. They reprogrammed the computer and said that fixed the problem . Started to leave and didn’t even get off the lot when it basically’froze up’ again. They kept the vehicle for a second time. When they called and said it was fixed, I was able to drive it but discovered to will ‘freeze up’ when trying to make a sharp turn(almost all the way to the stop), either to the right or left

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Ford F-150 Super Cab Diesel verdict →
