I looked on the forum for any mention of this, but didn’t see anything... I didn’t drive my Clarity for 5 days while on vacation and the battery (that starts my car and runs the accessories), went from completely charged to 0%. I took it to the dealer because I had not left anything on, like a interior light, and it was completely drained. The dealer told me this is normal because our Claritys are supposed to be driven and we only have a little battery. He said the Clarity’s battery may run down within a few days on its own because of the computer on board that’s still using the battery to run updates, etc. Does anyone have any experience with this? Thoughts? I’m thinking that I can’t leave my car at the airport or train station without planning to call AAA when I return.
