Lost Communication With Power Steering Control Module

While driving at highway speed, my 2025 GMC Sierra suddenly began slowing down without warning and lost propulsion. When I pressed the accelerator, there was no acceleration response. The vehicle felt like it was braking or dragging instead of accelerating, creating a serious crash risk in traffic. A warning message appeared instructing me to “Put in neutral and restart truck.” I followed the instruction, but the vehicle would not restart. It sounded like it was attempting to start, but it would not start normally. A “Service ESC” warning also appeared. The vehicle was towed by AAA to a GMC dealership and remains available for inspection. The dealership provided a diagnostic trouble code…

I own a 2022 Chevrolet Silverado LTZ Texas Edition with 51,000 miles, equipped with the factory multi-camera system and rear backup camera. The camera images are clear and all cameras function normally, but the forward/reverse guide/trajectory lines no longer appear. When the cameras are activated, a blue hourglass appears in the upper-left corner and the guide lines never load. This is a safety concern because the guide lines help the driver judge the vehicle's path and distance when backing up and maneuvering in tight areas. The loss of this feature reduces the functionality of the factory safety/parking camera system. I took the truck to an authorized GM dealer. They diagnosed a front…

I am reporting a safety-related defect involving the electric power steering system on my 2017 Ford Explorer. The vehicle displays a “Steering System Fault” warning, and when this occurs the power steering assist is reduced or disabled, creating a safety risk during low-speed driving, turning, and parking. When the ignition is on with the engine off, multiple communication fault codes appear, including U0100, U0131, U0140, and U0151. After the engine is started, these communication codes disappear, but the steering fault warning remains illuminated and no active fault codes are stored. This behavior indicates the steering system enters a fail-safe state during startup and does not recover…

While driving I will get a wrench symbol with a bunch of codes pop up u0121:00:28 u0131:00:28 u0137:00:28 u0164:00:28 u0199:00:28 u0200:00:28 u0212:00:28 u0252:00:28 u0256:00:28 u1012:00:28 p0557:00:28 p1935:00:68 p193e:00:28 I have also had it jerk while driving ( went down into first gear) while having no power to my gauge cluster ac nothing

Sudden Loss of Power Steering Assistance and Simultaneous ABS/AdvanceTrac System Faults I am submitting this complaint to document a serious vehicle safety incident involving my 2014 Ford Fusion SE. The vehicle experienced a loss of communication with the Power Steering Control Module (PSCM), accompanied by faults affecting the ABS and traction/stability control systems. During the incident, the dashboard illuminated multiple warning lights, and the steering suddenly became extremely difficult to operate. The simultaneous loss of power steering assistance and warnings involving critical vehicle safety systems created a serious potential crash hazard, particularly at highway speeds or during…

Daughter was driving and noticed initially that the steering wheel briefly lost power making right turns and applying the brakes. The next day while negotiating a curve the steering wheel froze and warning light came on stating “steering wheel assist fault.” Almost left the roadway before steering returned. Went directly to mechanic nearby. Mechanic scanned and found code U0131 Lost Communication with Steering Control Module A. Vehicle is unsafe to drive and left at mechanic for repairs.

I am remembering one incident I had years ago. It was my first year since I got my first driver license. I parked my car. While I was getting off with half of my body already outside the car, my car started moving forward. I jumped back in a car in a shock and tried to stop the car. I realized that I had not removed my car key. I also realized that a stick shift was in neutral position. I told myself that it was my wrong-doing, but after reading numerous complaints and lawsuits against Ford Fiesta over the last years, I am not so sure if it was my fault or the car's defect. It happened only once and can not reproduce this. Around the same time, I have also experienced car not starting…

I went to this dealership today to get my steering column control module reprogrammed. Which includes What the Dealer’s Reprogramming Usually Covers (Standard & Expected) • SCCM (Steering Column Module)programming/configuration — Loads the correct software and vehicle-specific data into the new module.• Steering Angle Sensor (SAS) calibration — Teaches the system the straight-ahead wheel position (critical for fixing hard steering and related codes).• Intelligent Battery Sensor (IBS) relearn — Calibrates the new sensor so the vehicle accurately monitors battery voltage/charging (helps with electrical gremlins and odometer issues). • Instrument cluster synchronization/reset — Clears the…

My 2025 Ram 1500 has experienced seven separate incidents in which the steering suddenly became extremely difficult or impossible to turn. The most recent incident occurred on August 20, 2026. During these events, I temporarily lose the ability to steer the vehicle normally, creating an immediate risk of a crash. A vehicle diagnostic scan recorded repeated U0131 faults for lost communication with the Power Steering Control Module in multiple control modules. The Electric Power Steering module also recorded communication faults involving the PCM, transmission, ABS, and body control module. The scan additionally showed an active B2204 ECU configuration mismatch. This steering failure has…

Truck worked perfectly fine, then it was parked for a week because I had to have emergency eye surgery. After a week, started truck. Truck started spewing errors U0121 and U0131. Managed to get it to dealership with no steering and am told it is a power steering module failure and the cost to fix is $1800. The truck is barely out of warranty and I have seen numerous posts on forums across the Internet of others that have also experienced problems with their 2019 Colorados and the recalls on the 2015s for the same issue. - Component: Power Steering Module - Safety: Absolutely no power steering, extremely difficult to almost impossible to steer. - Reproduction: Yes, truck is at dealership…
