I've seen online that others have this issue on their 2017 but there's no fix that I know of.
-Battery is good, it cranks fine
-MAF sensor, air filter, throttle body are clean
I've tried cycling the ignition on and off, leaving it on for a bit, keeping my foot on the brake too long, taking my foot off the brake early, mashing the throttle when it's struggling (which helps sometimes) etc.
So-
It's been doing this since 25k miles or less.
About once a week (car has 90k and is driven often) when the engine is cold or has mostly cooled down and you try to start it, it'll crank fine but longer than usual and then start shaking because the engine is literally hovering at about 50rpm or less!
After 3-5 seconds of a nasty, bogged sounding engine, it'll hesitantly fire up and slowly rev to it's cold idle. During this time the idle is a bit unsteady and will soon drop VERY quickly to about 500rpm and then rise back up to cold idle ~1800. When it drops it sounds like it dies.
This seems to happen more in cold weather but I'm not sure. It will do it about every week at 100 degrees and at 10 degrees (fahrenheit)
I can't tell when it will happen and rarely cold start the car with somebody, so I can't spray starting fluid every time I start it to see if its a fuel issue. There have never been active or pending engine or transmission codes.
Last night it did it and was pretty bad, so I'm hoping to get to the bottom of it before it ends up being a problem, if at all.
