OK, I purchased a 2020 Chevy Silverado 3500 for a fire department. The requisite emergency lights are installed and working. While working at a car wreck at night, using the truck to block traffic, with all the emergency lights on, the truck shuts off, including all the lights. Seems a bit dangerous, if I'm busy cutitng someone out of a car, to ahve all the lights shut off. Just seems a bit funny. The dealer said that there is no fix for this and GM said it would have to be done at the manufacturing plant.
