My Cybertruck was bricked after FSD 13.2.2

It literally tells you 80% for recommended daily driving on the charge screen and in the app

The charge screen warns that 80% is recommended when you try to set it above that value. It gives no such warning if you set it lower.

Tesla is fairly cagey about this; they don’t want anyone to get the impression that you cannot use the full battery capacity, but they also know that charging to 90-100% regularly will accelerate degradation.

Also, Teslas will start crying when the SoC drops below 20%, although this is not harmful. They just know that stories of stranded EVs will exacerbate the range-anxiety narrative.

Yes it does, that screen is the charge limit screen and in the app it is the charge limit setting.

It use to be (still is on our 2020 X) 90% for daily.
Anyway not the reason for this thread.

OP, any word on what they have found?

Nothing yet. I’m supposed to hear something tomorrow Monday or Tuesday. Expected resolution January 2nd but that’s dependent what they find tomorrow or Tuesday. Which I understand the delays due to holiday season.

Yeah totally and I know most of us on here (you included) understand all of that I’m just trying to prevent someone who may not know (or new to EVs) thinking the should not charge above 50%. The reality of current battery tech with the awesome BMS Tesla has in the rides I think the average person would be hard pressed to see a difference in the battery over, oh say 100,000 miles, if the charged to 80% every day compared to 50% every day. Now I say that and only charge to 40% (50% if I have extra solar) myself unless really need the extra juice. I know it likely will never matter enough over the lifetime of the truck but I still cannot help but to think that it “does help” to charge only to 50%. I’m genuinely not trying to be difficult or combative in my post, just think at times we should provide more details outside of saying things like:

Recommended charge: 15-50%
Recommended charge limit: 80%

You should not always be at the limit!

Those post are not helpful to someone who is new to EVs.

Hope they get it back to you fast. I’m really curious what happened here.

I don’t want to argue about this but you are wrong. You can set the charge limit in both locations. I’m simply saying Tesla puts the daily recommended (maximum) SoC in the software in multiple places. Coming at the OP about why did you charge to this level blah blah blah is not helpful and not what this thread was even about.

Depends on the battery formula, the old high-cobalt-manganese (like in my Zero) don't like sitting around that low. But a day isn't bad, compared to 'storage', which is months to years.

Yes sir, I hope to get it back soon. Hopefully I’ll hear something tomorrow, at least some communication of what really happened and I will share it on this thread for others to be aware. Luckily, I got a loaner, a model Y since that’s all they had. I already own the model 3 and other ice cars still so transportation isn’t an issue. Although, I wish I had my truck because I needed it today to transport a pallet of pellets for heat.

It absolutely is helpful because the majority of people see battery degradation as the #1 issue with EVs and the majority of people don't understand how SOC affects battery degradation.

No, it unduly worries them to an effect which is probably going to be outweighed by other lifetime effects in any particular car.

The current batteries are outliving the cars.

It’s less about longevity, and more about preserving capacity and range.

Any “worry” is induced by the warning to avoid charging over 80%.. “If high SoC is bad, then what is good?” This is why the question keeps coming up.

Neophyte EV owners need to acclimate to a different paradigm from the ICE habit of “drive until the E lights up and then fill to F”.

I suppose.

The paradigm is for me 'plug it in if I'm going to use half or so of its range, or if it's fallen below half and I want to use it tomorrow... otherwise no'.

A Tesla is even easier, since it knows to stop.

Here's hoping you (OP) get some good news shortly. My CT "bricked" on day three of ownership, back in the summer. Ended up requiring a rear drive replacement (the truck has been perfect since).

Not related to your source problem, but related to getting into an unresponsive CT, I found during that episode of mine that my old jump starter was adequate to initially get into the vehicle through the left-front wheel well (I could raise the frunk, for instance), but was inadequate to fully awaken the truck's computer, which as I recall took about half a minute from the bricked state. I tried several times, with my jump starter connected to the truck's jump starter posts under the service panel, as in your picture.

The high-amperage 12v circuit on jump starters are designed for a quick burst of current. After some seconds my old jump starter - and I presume many/most/all on the market - would turn off that circuit, leading the then-partially-booted truck computer to return to the bricked state.

I ultimately ended up getting my CT back up by jumping it with an ICE vehicle and conventional jumper cables. (Ironic, I know). I'm an hour each way from the Service Center and towing would have been logistically difficult.

The bottom line is that you don't need a high-amperage 12v circuit in order to boot the CT. But you do need a sustained (lower amperage) 12v circuit in order to do so.

I ended up buying a more expensive, more sophisticated jump starter that includes a 12v DC OUT circuit (different from the high-amperage 12v circuit used for jumping vehicles) for any future such episodes.

Keep us posted.

I had this thought as well... some Teslas can pop the frunk with just a 9V battery, but that's certainly insufficient to power anything.

What power pack did you get? I've got one that says it has 12V output but I've never tried it.

The jump starter I upgraded to was this model from Anti Gravity Batteries:

And then paired it with this set of alligator clips which plug directly into the 12v DC OUT port:

https://www.amazon.com/dp/B089KJCKV8?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1


I'm sure a lot of others will work. But many/most are like my previous jump starter and don't come with a 12v DC OUT separate from the jump circuit itself.
