I’d be curious too, if you do end up figuring out where you can find the build date of our trucks.My goal was for information only.
It’s not uncommon for vehicle manufacturers to make revisions at any moment during a production year based on market feedback, issues, whatever.
It’s good to know if your particular vehicle would or would not be affected by developing issues.
A quick example is the Harley M8 motor and its 5 or so oil pump revisions. Production dates dictate the start of a given revision.
I’m not up to speed on the Silverados.
And, relying on the manufacturer to issue a recall is a lost cause.
I only wanted a more defined date for future reference.
