Chevy Silverado 1500 - has a feel like running over rumble strips and goes away. Occurs at or between 60 and 65 mph. It isn't continuous at all. Doesn't do it at lower speeds or higher speeds that I can feel. Truck was purchased brand new in 2020

2020 Silverado 1500 custom crew cab 4.6L, V6. Purchased truck onaugust 10, 2020. Took it to dealer on August 17, 2020 because of jerking forward at low speed (20-25 mph) and rear brakes making a deep rubbing sound. Of course, technician said there were no problems (because he could not duplicate) the jerking motion. After picking up my truck, I noticed that they did not even address the brake issue, nor did the service advisor note it on the form.

I was stopped N the drive thru at in-N-out with my foot on the brake and the eco system had turned off the motor. It spontaneously turned back on without me lifting my foot off of the brake and the transmission engaged and the truck launched forward approximately 12-18 inches. This is the second time this has happened to me. It also happened one night about 2 months ago. This could have been very dangerous, I could have hit someone or their car or I could have even received whiplash myself.

Put truck into park and shut off, started to get out but truck was starting to roll, tried to stop it, pushed on brakes, no effect, kept rolling and gained momentum till it hit our cabin and stopped. Length was 200ft appx of roll. Message center said " press brake to start " which I was doing as it gained speed. Also during roll there was a ratcheting sound all the way during the 200ft roll which in describing it to dealer I was told parking pawl may not have engaged properly causing that sound. I was able to start vehicle after it hit cabin so I could roll it back away from cabin. Started truck after accident, no warning lights on, brakes worked. In rural AZ, on our property when this happened. Taking to dealer tomorrow.
