Returning from a 3.5 week vacation I encountered a strange thing for both our garaged 2017 RX350 and our 2014 ES350. Both started fine, but for both cars the screen had a message that basically said that it was doing a reload. All was fine when this was completed (about 10-15 seconds) but a few minor settings had to be manually reset. Very strange. Has anyone heard of this? And why did it happen?
