On 08/20/2026 at ~3:00 p. M. , I was driving my 2025 Chevrolet Silverado 1500 high country (VIN 1gcukje87sz331415) in stop-and-go highway traffic with super cruise engaged. The vehicle ahead was a truck towing a low, empty flatbed trailer. My truck came to a complete stop behind the trailer. While stopped, with no accelerator input from me, the vehicle accelerated forward on its own and struck the rear of the flatbed before I could intervene. My foot was not on the accelerator. It appears the forward sensors may not have detected the low, unloaded trailer as an obstacle, so when the system resumed from the stop it accelerated into it. No injuries. The other vehicle had a steel rear plate and was undamaged; damage to my truck is estimated at $3,549. 68. A vehicle that accelerates on its own from a complete stop into a stationary object ahead is a serious hazard. This was low-speed property damage only, but the same failure at higher speed, or with a pedestrian, cyclist, or child ahead, could cause death. I have an infant, and the thought of this happening with my child aboard is alarming. I am concerned that low-profile or unloaded trailers may not be reliably detected by the forward sensing system — a systemic limitation, not a one-time glitch. I ask NHTSA to review whether other gm/super cruise vehicles have experienced unintended acceleration from a stop or failure to detect low trailers. I notified gm (Chevrolet claim #108672421) and requested the vehicle's event data recorder and super cruise/onstar telematics be preserved. I am filing this so there is an independent safety record.
While driving on the freeway with my family in the middle of a snowstorm, my 2025 Silverado 1500 with 8,000 miles on it, suddenly dropped gears down to 1st without warning. The check engine light went on and I later found out it was the valve body that caused it. This could have cause serious harm to my family had I not maintained control of the vehicle. The dealership fixed the problem only for it to happen again a month later. The truck is still in the shop.
The following issues with my truck. 1. October 29-November 4. Rear crossing traffic not working. Front windshield camera not working, side detection now working. 2. 17 December adaptive cruise would accelerate when not in use. Side camera not available. Back up camera not in use, all dash related to the radio, phone and google not working. 3. 5 Feb 26 blind spot indicator, forward collision, and rear crossing traffic warning working. 4 with all this issues this vehicle is an accident in motion a safety hazard to me and any body around this vehicle GMC has had this vehicle 4 times and can not seem to get it repaired.
On the evening of August 27, 25, when exiting the highway ramp, the vehicle's engine suddenly stopped and stalled, the gear automatically shifted to neutral, and the hazard lights could not be turned on. After about 2 minutes, it restarted normally and turned on the hazard lights.
