Bricked Truck After 12V Swap

[mroe]

Two weeks ago, my truck started showing the "Replace 12V Battery" warning. I checked the voltage in the RiDE menu and everything looked normal (13-14V). The car was fully operational with the exception that it would not install the latest software update because of the the 12V error. The soonest I could get a mobile service appointment was a few weeks out.

The service tech came out to my house today. It turns out the RIDE menu only shows the primary, not secondary, battery voltage. The secondary battery voltage had dropped to just under 12V and presumably that's the signal for the error. The tech said they'll just replace both batteries as a precaution.

After about two hours of work, the service tech notified about the bad news: the car was wouldn't boot after the 12V swap. The new 12V batteries were solid, connections good, but the truck was bricked.

Service tech decided it needed a tow. Windows and frunk were open when the truck went dead so they hilariously duct-taped the frunk closed for transport. Tow process was sketchy on skates and visually looked threatening to the drive units.

I haven't gotten any update from the service center since they received the truck.

Will update this thread when I learn what went wrong.

Damn, sorry to hear that!! Hope they put priority on this, since it happened on their watch.

Electric cars are simple and reliable with little to break down or service. ?

Can't help but wonder if the techs accidentally/carelessly shorted something out while swapping.

We had a 12v battery issue back in March. The mobile tech came out and tested the battery and said it was going bad. He replaced the 12v within about 15 mins. and all has been good. He even did the all point inspection and refilled the windshield wiper fluid.

I am hoping that they can figure it out. I would be ticked about the duct tape on the paint. Make sure when you get it back that it has been detailed and there is no tape residue.

My parents attic probably still has my first EV racing set... and I bet it still works.... trouble free for 35 years...?

Yeah, they need to connect both 12V positive leads almost simultaneously which is difficult at best.

They would be better off disconnecting the common negative leads to the vehicle, combining both of those negative leads to just a single common negative cable then they could connect both positive leads at their leisure and finally connect the one common negative lead to the vehicle. That would 100% eliminate errors caused by not connecting both positive leads at different times.

What kind of stupide design is that? If it's 12V it shouldn't matter one or 2 batteries at the same it would be less amperage but same voltage.

They are independent systems.

Is this limited to vehicles with two 12 V batteries? Are vehicles with one battery and the capacitor not affected by this?

Don't believe so, My R1S definitely has the newer (Bat + cap) system and had the same issue - even had the weird "bricking" after the replacement, the tech could not get the new battery to be "accepted" by the vehicle and it was unusable. They had to come back later that day with a different tech and after another hour or so of fiddling they were able to get things sorted though it seems to have created other issues (drivers side bluetooth and air compressor are dead - being addressed this Friday). But I think this can happen to anyone.

My story - with updates through the process - is here

Yes, a poor design.. and to make matters even worse, they decided to basically split the vehicle 12V system devices into one 12V battery powers the left side of the vehicle and the other 12V battery powers the right side of the vehicle. So if you don't reconnect the two positive leads at almost the same exact time, you get systems on different sides of the vehicle powering up at different times! Can you imagine the problems something like that would cause??

Yeah, I can, I'm pretty sure I was a victim of them

They need a procedure for this because battery warranties are expiring for people. This is worse than replacing an iPhone battery.

You would think they would just loop and wait for the other side like every other software defined system
