Total loss of Power Steering ! Warning light display: "Steering Assist Fault", "Service AdvanceTrac", turn signals unable to lock and release. Hard Fault codes present: U3000 96-C8, C200D, 49-48 C1B00, 64-48. This problem started somewhere in the last quarter of 2025, it started with intermittent and sudden loss of power steering, while driving, which is very much a safety issue, especially when my wife does not have a lot of strength in her arms while trying to maneuver a vehicle with manual steering only. It has happened to me as well. It used to be that when you get to a save pull over point, shut vehicle off and do a restart, it would reset back to normal operation, most of the time…
I am getting a Steering Assist Fault message on my dash as well as code C1B00:49-2F. I took my vehicle to the Ford dealership and the deemed I have a faulty steering rack. I noticed there was also a recall out for other 2021 F-150's experiencing similar issues. My VIN was not included.
Owner, who had bought the truck new approx. 3 1/2 years earlier, had driven about three miles on dry, paved, residential, hilly, roads and was returning to where he was staying when he came upon a waiting line of cars. He turned around to go a different way. Coming to a slight curve the power steering (EPAS) went out. Struggling to make the curve, the power assist kicked in and jolted him off the right side of the road. Had the curve been to the left, the truck may have been thrust into the path of an oncoming vehicle. Owner then slowly soldiered on, with the truck making an intermittent noise as if trying to activate the power steering, which it sometimes did, causing the truck to swerve…
Vehicle power steering failure, causing locked steering. After reading, am finding this is a major problem with many Ford models. There has been recalls on many other models.

My 2021 F-150 has been diagnosed with a failed electric steering gear Code PSCM C1B00 49 2F. I understand there was a recall on some 2021 trucks with similar steering issues, although my VIN is not included. The part is on national backorder and my dealer says there are approximately 150 vehicles ahead of mine. This is a safety-related steering component, part number "ML3Z3504G"
I have a 2014 Ford Explorer sport. I notice the airbag light went on. I ran my obd scanner, initially it gave B00A0 and B0061 error codes. After a couple weeks, my EPS doesn’t work after I turned the engine on, it won’t turn left or right. It went away after turning off and back on. It happened again after couple of days, i was leaving the gas station and the message went on and i tried to restart the engine twice, but it still didn’t fix it, but i had to leave cause there are people behind me waiting. I tried to drive forward and just end up blocking the way cause I couldn’t turn the steering wheel and people are getting upset. Thank God it worked after the 3rd restart. Then 3rd time it…
