2025 GMC SIERRA 2500 Steering Problems

i experience a steering wheel shimmy between the speeds of 70- 75 miles an hour

While towing a less than 2000 lb trailer I had total loss of power steering when speeds dropped below about 5 mph. I got off interstate and was turning right at the end of exit ramp and I could barely turn the vehicle. At the next stop sign it did the same thing. I stopped turned off the vehicle and restarted it and it continued this for the next few miles. Then just as suddenly as it started it stopped doing this and worked fine the rest of my trip.

The contact owns a 2025 GMC Sierra 2500. The contact stated that while driving at an undisclosed speed, after driving over a small pothole on the road, the alignment was dramatically altered, causing the vehicle to slightly veer out of the intended lane even though the steering wheel was centered. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The contact stated that he previously owned another vehicle of the same year, make, and model that had experienced the same failure and a case was filed with the manufacturer for the vehicle, resulting in a buyback. The failure mileage was 2,000.
