I had this happen today. I purchased the 2020 silverado 2.7L Turbo 2 days ago with 5 miles on it. Drove it a good amount yesterday and today and at 150 miles I hit the gas to go around a vehicle that cut me off and it felt like the engine shut down. ESC light, brake light, tow light, and check engine light all came on. It decelerated quickly going into a drive safe mode but I was unable to go over 20 mph. Pulled it over, turned it off, restarted and everything went away except the check engine light. On my way to the dealership, I gave it a little gas because I was going on a hill and it happened again. Rinse repeat and finished my drive to the dealership, we'll see what they say.
