Started hearing rattle noise especially in colder temp below 30F coming from the driver side - seems like just from behind the console - anyone else experience this and eventually fix? 27K and still under warranty

Yep. Too many rattles to keep track of. They often come and go, and different ones become prominent at different temperatures. I've given up trying to fix any of them. These 3G RDXs are rattle boxes.

You could try shoving foam in between the dash and the windshield. Some people says that helped. It didn't do squat for me. I get a nasty one seemingly coming from the passenger side dash somewhere in the footwell.

Do you have an Advance trim? The HUD is a common cause of rattles in that area.

No, I do have TECH and I am glad I did not spent extra for Aspec I was crazy about it. Indeed, my sunroof rattles like hell in winter, in summer its pretty quiet, the dealer said that crap is not "fixable" ; however they adjusted back door for mooning sound. Now its serviced at the dealer for bad fan motor and whistling sound. The list of replaced items in this 3 year 27K car is kind of long, but still has 9 months full warranty so if anything needed to be replaced it will be replaced.
The only what I am finding now is cheap front suspension. Not sure if replaced control arms at 7K had anything with it, but my RAV4 with 60K sounds a way better and solid (front suspension) than this 27K miles vehicle. I drove a couple of others RDX 20,21, and even 22 all with over 20K has front suspension kind of like its loosen. Of course dealer does not replace control arms in their demo cars so I drive old mattress.

Good luck with the rattles. They can be most difficult to pinpoint ecactly where they are coming from sometimes. Our '19 (19,000 miles) has been 100% rattle free until the past few months where it seems like rattles are coming from all over now. In the past a big help has been letting my wife drive while I try to twist, turn, and grab anything that might be the culprit, trying to get it to stop.Once you know what part is rattling, at least you can start coming up with a game-plan. Looks like I need to get moving on that.
Agree on the suspension, or something in that area. We just started test driving a few new vehicles over the last couple weeks and (of course...they are new) there was quite a difference how quiet/solid the front end was----we drove a GV70/Palisade/Telluride all 3 of which well exceeded my expectations. I remember thinking how abnormally large the RDX infotainment screen seemed when we bought it...but compared to these 3 cars we drove...not so much anymore.
