I can't post links yet because my account is new, but the above was copied from a Dec 11 article on the site named "cars" followed by "com" Google "2019 Toyota Prius: Recall Alert" to find it. One more nonspammy post and I can add it myself
The Noncompliance Information Report (PDF), with a few more details about the problem, and December 10 dealer letter (PDF), which identifies this recall, in the U.S., as 19TA21 (19TB21), have been posted on NHTSA’s website.
