I reached out to Thule again to see if they've been able to produce compatible mounts. This was their response:
"To date, there has been no update on this vehicle. As my colleague mentioned, we will update our website as soon as fit information becomes available."
I do have the factory cross bars, and they're fine. No noise and they fit in my garage. I was considering swapping them out for the Thule cross-bars as I believe they typically have models available with a wider horizontal mounting area suitable to carry both a kayak and another mount, but we're deep into the 2021 model year and they don't have a product yet, so I'm not hopeful that the situation will change anytime soon.
I got the OEM ones. They do sit high and come with the key. Mine were actually a dealer add on but they are priced at $495. Not sure from the link but I've tried buying stuff from them and...well lets just say IS needs to do an overhaul on that site.
