I had that warning pop up for a few days, called customer service, waited a couple days for my local service center to reach out and by then it went away and never came back again. No updates involved.
I also have 20s on the Touring and haven’t had any issues so far but only 2k miles in.
My code has never been used. Please consider using mine!
Code: XPXR585M

I didn't take a screenshot but it was just boilerplate like "Enhancements for the robustness of the software." They didn't state anything specifically.
