2015 Ford F-150: loss of power steering

Filed Oct 7, 2026 · Steering · FL

I am writing to express my serious concern about a power steering failure in my 2015 F-150. Within the last few weeks, it began losing electronic power steering assist intermittently. The loss of assist happens suddenly, with no warning light or message on the dash. When it happens, the steering becomes extremely heavy and difficult to turn, and it can happen at any speed. The vehicle is very hard to steer without power assist, and becomes a serious risk to avoid an obstacle, hold my lane in a curve, or make a necessary maneuver in traffic. A sudden loss of steering control like this can easily lead to a serious accident, with the risk of injury or death to me, my passengers, and others on the road. Because of this I have already had a close call. The power steering went out while I was making a right turn at a traffic light on a major road. The truck drifted wide into the oncoming lanes, and I had to brake hard to avoid a collision. I pulled over and turned the truck off. When I started it again, the power steering seemed to work, and I was able to drive to the nearby Ford dealership to ask about the problem. Because I was about 30 miles from home, they advised that the best thing I could do was to get the truck back to my local dealer. When I brought my vehicle to my local dealer, the service department confirmed that recalls and bulletins exist. However, they told me that my truck's VIN does not fall within the affected range. This is the pattern I have seen every time: the power steering returns after the truck is restarted, but then goes out again at random, with not warning, and with no way for me to predict when. It is clearly not normal for a power steering system to fail on a vehicle with only 60,000 miles. A steering system is a critical safety component and should be expected to last well beyond this mileage. A failure this early points to a defect, not ordinary wear and tear,

The timing belt/chain is failing on F-150 trucks and multiple people have sent in issues. i think from 2015-2018. It looks like you are already looking at other Fords with same issue. what i was told is that there could be sudden stalling: If the timing is thrown off or the chain snaps, the engine cuts out instantly. Losing power steering and engine power while driving in traffic creates an immediate crash hazard. Severe Misfires and Power Loss: A slipping chain causes rough idling, violent shaking, and an inability to accelerate which happened to the truck. Due to this i had to get mine fixed in June of 2024 i have attached the invoices. I tried to upload invoice but said there was an error

For the past 3 days, I have had intermittent loss of steering from a power steering failure while driving on interstates/highways. Almost completely unable to steer it to safety on the side of the road. Ford has a recall(15S18), but I was told its vin-specific. My truck's vin does not fall under the recall, yet im having the same problems as the recall claims. Reaching out to see if this can be resolved and have a recall initiated. Thank you

PS111 Error Cody: Throttle Body Assembly is malfunctioning. My vehicle lost power steering and went into full shut down mode a dozen times over the course of driving it the latest ~500 miles with the truck shaking at a stop before restarting it and working again. Many times this could have been FATAL collisions as they happened on roads without shoulder lanes. This issue is SUPER scary to have your vehicle randomly shut off on you leaving you minimal time/distance to react and often in the middle of the road with multiple lanes. I've had it at the Ford dealership for 3.5 weeks where they are trying to fix it for $1,100, however, they said Ford currently has 15,000 of the same part on back-order. This issue should be a safety recall immediately, in addition to the shear number of the same part on back-order is clearly an indicator that Ford has an engineering issue and should be held liable to replace the part that frequently defaults at their expense but also to keep the roads safer.

When driving my truck on the freeway the steering became hard to turn and to control the truck. Steering wheel would turn and click but hard to keep straight on road. was able to drive slowly to a auto repair shop, almost nearly crashed into railing on freeway. Took 190 days for ford to deliver the part. (Sounds like this happened before to other vehicles). The issue was the steering gear stoped working.

When driving on the highway an alert popped up on the dash stating Hill Descent Control Fault which was followed quickly by Service Advancetrac and a yellow wrench and see manual. These warning continued to cycle and the truck seemed to lose ability to maintain speed as is slowed down and the steering became difficult. I was able to get it off the highway without incident as there were not many vehicles on the road, but if it would have been busy, I would have been in trouble. Once on the shoulder I placed it in park and the truck began to shudder and run rough. I turned the truck off and let it sit for a few minutes and then restarted it. Upon restart everything appeared normal and there were no warnings, I was able to continue to my destination. I called the dealership and they sounded like they had heard this story before and told me I could bring it in within a weeks time. I was also told that it would not cause any damage to continue to drive it. While waiting for the repair I did have to continue to drive it and this same thing would happen randomly just going down the road and all of the sudden you get a warning lose the ability to maintain speed and steering becomes difficult. Being on the highway in this situation is dangerous since you never know when it might occur. After going to the dealership they listed the repairs on my form as: installed BL3Z9E926 B Throttle Body and Motor Asy installed BL3Z 12029 C Coil Asy - Ignition installed BL3Z 12A402 A Boot - Ignition wire prot (5 items) installed CYFS 12 YT4 Spark Plug (6 items) The parts and labor of this repair came to $972.56. I have read forums online that that state others have had this repair done as well and some people say their steering rack was replaced as well. This repair was just done yesterday (6-26-21) and I am hopeful that it will fix the problem. I feel that based on the reading I have done this has happened to lots of people and is dangerous, so I wanted to report my incident.

I own a 2015 ford f150 and while going through the mcdonalds drive through, at approx 5 MPH I lost power steering unable to turn left or right. Errors displayed on dash for electronic power assist fault, advance trac fault, hill start assist fault. Also no cruise control. Pulled over in an empty parking spot, shut down the truck and restarted the truck, but there was no change to the string. Unable to drive further, I had to have the truck towed to nearby dealership greenway ford in orlando. Per the service department, the steering control module is bad and will require replacement of the steering rack. Cost to me $1700. I purchased certified pre-owned extended warranty, but unfortunately the warranty doesn't cover steering rack. I am grateful we were not driving on the highway, as this could have turned out horribly.
