For all those experiencing battery issues, this is by no means the only vehicle that has that issue. Gen 5 RX came out in '23. They quickly came out with a TSB:

The Lexus Gen 5 continue to have battery drain issues both hybrid and, it appears, straight ICE

When I say Lincoln at least appears to be trying to work the issue, tamping down the parasitic drains via SW updates, that's something Lexus has been VERY slow to work on, best I can tell, at halfway into the second MY of the platform.
(I've been a fan of Lexus, 5 RX since initial introduction, happy with my current Gen 4 '17, but their Gen 5 has been a mess. They haven't had an injector tip issue, but have had on-going transmission issues (requiring up to full transmission replacements). They've had fit/finish issues resulting in misc. shouldn't-be-occurring noises. Software updates are a bit of a running joke. The Gen 5 has been what got me searching for an alternate - very happy I came across the updated Nautilus.)
