On the topic of recalls in general. An old buddy of mine in the auto industry believed that legacy automakers would do bogus or superfluous recalls on occasion just to get people back into the dealership. Where sales people could mosey into the service area and talk to the folks with older cars.

No hard evidence for it, but it did make me think. (I don't think this applies to Tesla)

Only on the cybertruck, the Y and 3 are still mostly 12v

I wonder why all electric cars aren’t designed from the start to use 48v.

Because all of the IC's that are attached to the battery are designed for 12V. Things like solid state relays (BTS7008 for exammple) and the 5/3.3 volt regulators.

To the contrary, the fact that this is a physical recall is perhaps the most interesting and noteworthy thing about it.

Are you hodling TSLA and concerned about the costs? I could see that being interesting...

No, but we own one of their vehicles and in years have never experienced a recall that involved physically recalling the vehicle. This one doesn't apply to us, but if it did, that alone would immediately make it stand out compared to every other recall we've experienced with the product (which have never had any effect on us whatsoever).

Interesting timing on this considering the earnings call coming up

Yeah, typically when you have bad news you want to get it all out at once. I know nothing about Tesla.

Considering the battery is such a core component, I don't see why they would waste any time on it once they've realized and narrowed down the issue.

12v is easier to adapt and take parts off the shelf. Remember that EVs weren't quite obviously the future at some point.

I have to wonder if this ever happened with the 6v to 12v transition somewhere in the 50's-60's

Component availability mostly, the entire automotive world is designed for 12v systems.

I would not have expected many shared components between electric and ICE cars. Especially Teslas.

Curious how it worked, I found https://www.tesla.com/ownersmanual/model3/en_us/GUID-A7A60DC... > At the bottom of the rear door pocket, there is a slot in front of the release cover. Slide your finger into the slot and lift to remove the cover. Pull the mechanical release cable forward. I wonder how people are supposed to be able to find that when in an emergency sitting in the backseat of someone else's car.

They're in even worse luck if they are in any number of cars that have rear-seat "child safety" locks that prevent opening the door from the inside. There's no way to bypass that except from outside the car.

That sounds pretty good in comparison to the Cybertruck, because that one can't be opened from the outside ever, if the battery dies.

The manual bypass for the driver and passenger seat is much easier to find than the one in the rear. Too bad the driver can't help rescue everyone else, because the door handles are electric.

Interesting, thanks!
