2025 GMC Sierra 2500 Brakes Problems

“On highway taking an exit. The brake pedal sank and did not engage at normal pressure, I had to push the brake all the way down for it to engage. Concurrently the steering wheel locked up where I could not turn the wheel at all. I drove straight through the exit ramp to the entrance ramp, luckily no one was entering the highway at the same time. I very well could have hurt some one else or myself. The steering wheel finally engaged where I had full power steering again and I was able to remove my truck off the highway and cautiously drove to a parking lot to get it towed. …”

“Power steering pump failed when decelerating after 9500 miles. When power steering pump fails, power assisted braking also fails. Upon deceleration, I could not turn the steering wheel at all or stop the vehicle without extreme pressure on the brake pedal. I narrowly avoided impact with a concrete barricade at the entrance to a parking lot. GM issued a technical bulletin (DCS7112) on January 16, 2025 identifying the problem and failure and directing dealerships to replace the pump on inventory vehicles. No mention was made to repair or notify owners of the potential problem.”
