I have had the keyless start issue since Nov 2019 on my 2016 Touring model but it was so intermittent it actually went away a few months. It would come on periodically with both keys, both keys with new batteries as well. I finally had a chance to take it in to the dealer while the light was on. They claimed it was actually the start/stop button causing the issue. They replaced it and the light has not come back on for a week now so they might have been spot on. I think it was a $240 line item with labor but thankfully the extended warranty covered it.
