What % of owners have experienced 12v battery failure?

[foxerson]

I have been fortunate. 1.5 years and 30k miles without any 12v battery problems. However, I know that many others have endured frustrating failures. It got me wondering just what % have failed.

I imagine that build date, mileage, dual vs. single batteries, charging habits, and environmental conditions all play a role in the likelihood of a failure. But, that's a more complicated data gathering effort. So, I set this up as a basic yes or no to see if we can come up with a simple % from this community.

I'm sorry but I'm afraid to vote in the poll because if I call attention to it I know my fate will be changed.

I guess that makes me braver (or dumber) than you for temping fate by posting this poll.

I have 2 Rivian’s and can only vote no once :shrug.

Ultimately there's only two types of owners: those who've experienced a 12v failure, and those who haven't experienced one yet. ?

Same as every other motor vehicle made either ICE or EV.

FWIW my 24 Maverick 12V died in the first 3 months, but my Rivian hasn't yet.

This makes me wonder tho is the 12V battery 'jumpable' like we're used to doing in ICE cars?

It is from the rear bumper. I bet putting it on an optima charger would charge it and tell you the battery health along with desulficatefy it (if that's a word)

Definitely doable (That's how I got mine unlocked and able to retrieve my work laptop from it) but it requires A LOT of amps so a small jump starter won't cut it

I saw somewhere, maybe it was this thread, someone saying how you cant charge it properly though from the hitch leads. Jump, to be able to do minimal things with the car, but I thought that's it.

Do I vote twice if I had two failures? ?

Sounds like we can call it a wash.

IF you're afraid it will be changed, I'd say you just let us know your experience!

Wonder if dual 12 V battery has a different failure rate, or if related to VIN/production date
