Thank you all for the quick responses and insightful comments—I really appreciate you sharing your experiences!
It is very helpful to know that others haven't run into this even in mid-30s ambient temps. That certainly points towards a specific component or thermal tolerance issue unique to my car rather than a universal platform bug.
My local dealer is currently investigating the issue further and is scheduled to give me an official update on August 24th. I will make sure to update this thread as soon as I hear back from them.
Thanks again for the input!
