I figured I'd post this since it doesn't look like anyone here has experienced this issue yet.
Since the car is going to the dealership for a coolant leak issue, I figured that I'd also ask the service manager to look into an engine clunking noise that only seems to appear when the car is turned off in cold weather. Since moving back to Manitoba, where it gets much colder in the winter than where I lived in Alberta, I've noticed that in cold temps (usually -20c or colder), the clunking noise appears. See video below (notice the odometer shows just over 17k kms, currently the car has over 65k kms).
The clunk may be a little hard to hear because I had the doors closed in the video, but it's much more audible with the door open or the windows down.
I have not noticed any significant changes in drivability or performance, so I've kind of lagged on getting this looked at until now. Anyway, as soon as I mentioned this issue, the service manager suggested that it's likely a frozen motor mount, which actually makes a lot of sense. He said that the CX-9 uses oil-filled mounts, and that they are prone to freezing up in extreme cold. We recently had a few cold snaps here (-35c to -40c), so it sounds like the mount(s) have just frozen up again.
We'll see what they find after they take a closer look.
