I have a 2018 2.5i that has a strange, very brief, whine or bearing noise on start-up about 1-2 seconds after the engine starts. I notice it only occurs when the engine is cold. Also, it makes this noise with the AC off, so I doubt it's the AC compressor. Thoughts?

Took me several plays to ID the noise you're referring to.

My old '99 Subie has a whine on start-up cold that I stop by counting to 3 seconds after start and then shifting from Park to Neutral to Park quickly; fast idle and noise drops away. Noise won't recure that day. Been doing the noise thing 'for a long time, but not since new.' ... total guess this noise is starter related, maybe the fast idle grabs starter gear and won't immediately release it after the flywheel start engagement. If this guess is correct, the starter is overspun (whining) for a short while. Starts reliably; so it's not broke in my book, and I'm not looking to fix it.
