Accepted the noise as normal. Some 5.3's louder than others. Felt the clunk in drivetrain in a 2015 Silverado, so guess that's normal too. Time will tell.

I have a 2016 1500 Silverado 5.3. Since its been colder out (maybe 32 or colder), on cold start up there is a rhythmic loud tick/knocking sound until warm. It is a loud noise you can hear it 10 ft from the truck. It starts about 5/10 seconds after cold start up and once engine is warm goes away. This happens every time i start the truck if its cooled down since its been cold out. Have about 7400 miles on the truck. Brought to the dealer and they thought PIP5395A would take care of it, it didn't (they didn't bother letting the truck cool for hours and start to see if it fixed the problem either, winter here now). I'll bring it back in but wanted to post this to see if anyone has had the similar sound/issue and if so was it diagnosed and addressed? Not sure if its related with something in the trans but when I coast down to 20 from about 30 mph then press the gas to go the truck clunks and slams into 2nd? gear from 3rd? kind of worrisome. Not sure if I made the right decision to buy this truck... Video link: Thanks, Brian
