COMPONENT / SYSTEM FAILED: The Electronic Power Steering Assist / Power Steering Control Module (PSCM) and vehicle electrical ground system failed. The vehicle is available for inspection upon request. RISK TO SAFETY & NEAR-MISS INCIDENT: While driving on the highway at 62 mph in light rain, the electronic power steering assist cut out completely without warning. The steering wheel instantly became extremely stiff and heavy, giving the immediate sensation of locked steering. Because power assist cut out without warning, the vehicle drifted toward a concrete side wall and adjacent highway lanes with heavy semi-truck traffic. I had to exert significant manual force to keep the car straight, gradually decelerate, and bring the vehicle to a safe stop. This failure created an imminent risk of a high-speed rollover or collision with surrounding tractor-trailers. DIAGNOSIS & INSPECTION STATUS: The incident occurred over the weekend on October 10, 2026, while the dealership service center was closed. The vehicle has not yet been inspected or reproduced by a dealer, service center, or law enforcement, but will be presented to the dealer as soon as they open. WARNING SYMPTOMS & TIMING: There were no warning lamps, messages, chime alerts, or steering symptoms prior to the sudden failure. The failure occurred abruptly at highway speed.

What owners say
While making a slow turn I heard a popping noise then the steering locked up completely. I shit the car off and started it again to regain steering and get the car home. I used FORSCAn to retrieve codes U0401 and U0415 for the PSCM, both codes have same time frame. This indicates the PSCM lost communication with multiple modules at the same time during a low-speed turn, resulting in loss of power steering assist / steering lock. This is a safety issue as described in Ford Recall 19S26, but my VIN does not show this recall as applicable. Vehicle has not been repaired. Codes have not been cleared and are available for inspection.

I have a local mechanic looking at it but they said the part is on back order which means this must happen a lot. They finally got the part and now are saying it won’t program so are needing to order another part. When I turned the car on to leave my destination it said service powersteering system and abs, but before that there were no warnings. I unplugged the battery for 30 minutes to rest the car and everything worked fine for another 1, then driving down the road it went out again.
