Normal driving 40mph brake failure and power steering loss. Towed vehicle to dealership

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.

Reverse lamps are not bright. Camera does not brighten area either. Very unsafe to reverse in the dark. Have to touch the brake pedal to be able to see while backing. Also have tried the LEDs in the mirrors while backing- although the LEDs are bright- lights to see while backing are insufficient on the stop lamps.

The contact owns a 2025 GMC Sierra 2500. The contact stated that the front driver’s side door handle failed to operate as needed, and the contact was unable to exit the vehicle through the driver’s side door. The vehicle was taken back to the dealer, and a new handle was ordered. The part was replaced under warranty. Soon after the repair, the liftgate failed to open or close as needed and became inoperable. The vehicle was taken back to the dealer for the liftgate to be serviced under warranty. The manufacturer was not notified of the failure. The vehicle remained with the dealer unrepaired. The failure mileage was approximately 300.

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. I have not tried to drive sense incident as it is at the dealer for service. The GMC Dealer has not inspected the vehicle yet, they are backed up with other services. There were no warning lamps at the time nor before the incident. Symptons see bellow. I have had issues with the brakes and it has been to the dealer 4 times including this incident, Service issue #1 at 21,501 miles -Breaks were pulsating, squealing and rough and it was shaking the steering column - The smell of burning breaks was present after drives -Solution they sanded down the hot spots on both rotors and pads for the front brakes Temporarily fixed the breaking and steering column shaking ( it did not solve the burning break smell problem. Service issue #2 at 28,142 miles Breaks were pulsating, squeaking, and steering column shaking - The smell of burning breaks was still present after drives. solution new front brake pads and rotors. Service issue #3 at 39,893 miles Rear brakes locked up while taking a turn on to a street Breaks were pulsating Squeaking and steering column shaking Smell of burning breaks is still present after drives solution machine front brake rotors. could not reproduce brake locking issue Final issue as mentioned above #4 @43,426 miles I cant help but think the constant break issues were warning signs.
