Thanks Pistols. Glad to hear. I had a '15 Silverado 2500 HD LTZ 6.0 that did not have those noises. Probably those new Taiwan chips made on Friday.Yes, mine does the same. Will also be multiple clicks and clunks and noises from inside the cab after shutting the vehicle down if you stay inside it long enough.
Edit: I do believe all these sounds are normal. Fuel system prime at the time of vehicle unlock and shutdown procedures after vehicle shutdown. Fans, vacuum seals, electronic protections ect.
