HVBATT_a170. Msg

[tthrower]

Anyone familiar with that and what it means?
I have the yellow turtle icon with msg”acceleration and top speed reduce. Performance may be restored on next drive”.

CT is driving fine and I don’t notice anything out of the ordinary.
Tks

I had this and several other HV Batt errors for a few hours. It went away after the vehicle went to sleep for a bit. It’s been a week and they haven’t come back again. I was unable to charge too.

I believe that’s a High Voltage battery error. Looking at some post on other sites it seems it could turn into a big deal from getting stuck to needing to replace the HV battery

thanks. I also had problems getting it to charge several days ago. After driving it for a bit it charged just fine. Temps were in the 20’s so I thought it was cold related.

Yeah, below zero here too so I’m hoping it’s a cold related software bug or something. I have a service appointment later this month to double check things.

Tried to initiate charging this morning and received HVBATT_a174 message. Temps are low 30's here currently.

Yesterday got mine back from Service, and this immediately happened to me. Went into turtle mode. It back in the shop, I will let you know what service says...

Any result on this?

They said coolant levels were too low after the recent service because there was an air bubble somewhere. Topped it up and havent had issues since.

Thanks - just got this error this morning. Appreciate the info!

Just to be clear, the service org topped it up. It was after the front drive replacement that I had done..

I brought mine in this week - tried all the normal tactics of reboot, sleep etc and it didn't clear. Service advised me to bring in right away. They reset the BMS, supercharged it and kept it overnight for observation. Did a number of test drives and it was all fine.

One interesting note... on my drives the SOC displayed was stuck at 75% and wasn't changing.

So software bug? A little unsettling. Hopefully all stays stable.

I did get 2024.45.32.10 (fsd 13.2.6) pretty much as soon as I got home after the service.
