2013 Traverse has newer battery and starter. Battery is charged. Whirring noise when the key is turned, no engagement or attempt to start. Any ideas what might be the problem?

If the starter is spinning, but not turning the engine, it's possibly a bad starter solenoid (most likely), or you've stripped some teeth from the flywheel, which have now lined up with the starter gear (less likely).

You say a "newer starter." What was the previous issue? Maybe your previous starter issue was really teeth missing from the flywheel and now it's lined up with them again.

Missing teeth doesn't seem to happen very often these days, but my son recently bought a 2006 Cobalt with 140,000 miles that he intends to build a kit-car from and he just discovered it has this problem. (He knew when it bought it that there was some kind of starter issue.)

The starter was replaced a couple years ago. Prior to that, it was about 50/50 that it would start. It was making a similar sound to what is happening now.

Sounds like starter drive is slipping / not engaging. That's the usual problem on a it does or doesn't crank over issue. If it sounds the same as a previous repair fixed, then that noise it probably is the same issue.
Rebuilt starters are not as ''robust'' as a new replacement.

An old school test to try is to tap the starter with a hammer prior to attempting to start. If it starts afterwards than the issue Is the starter. Worth a shot at a free troubleshooting method

take the starter off and look at the flywheel, if the teeth look good bench test the starter.

This used to be a common problem back in the 60's and 70's, surprised that after more than 40 years, they haven't solved this problem.
