Service Alert: VCFRONT_a557_TLVBMS

[Pianewman]

MacO512: I wonder why I always get an instant response in person? SC customer service variation, I guess.

Have you actually tried it, or are you just following Tesla's instructions?

I wonder if it’s because they’re managed by different teams, with different priorities.

Have you tried SC’s in busy areas?

I have zero concerns about driving, I'd need to see an error in the regular user Tesla screen to worry about that. I will wait for the next update to see if the issue is still there. Eventually if the issue persists for many months I'll probably schedule a service appointment.

Good points. Thanks!

Seeing the same VCFRONT_a557_TLVBMS_ConfigFromBmbModIdFailed error on a 23 MY. Got the error on Monday. Glad to see others got it as well - kinda comforting!

Well, Tesla pulled back 2023.32.4. Maybe it’s related to this service alert.

Is anyone also getting VCFRONT_a059_inputResistanceHigh along side the VCFRONT_a557_TLVBMS_ConfigFromBmbModidFailed???

I have not gotten that message. Another forum post indicates it might be a bad LV battery.

I was poking around in our new MYP (Austin build 8/23) service menu and saw the same alert. Wasn’t there prior to the new 2023.32.4 firmware, so wondering if a software bug (had been in there to install a Homelink module)? Have a service appt set for 9/18–will post when I find out more.

Any updates on this JCNE?

Nope

Looks like 2023.32.6 is being rolled out

 

[gjsrv2]

Has anyone received 2023.32.6? If so, did it fix this problem for you?

 

[Sai Ko]

Still waiting for the update. Hopefully it resolves. Service team looked at it and said wait for new update and nothing to worry about the alert regarding the mismatch in service screen

Thanks for the update. I’m taking mine in tomorrow, expecting the same response. I’ll report back once i get a response.

Thanks Sai Ko and jecsun. I just got a call from Tesla Service. I didn’t really understand exactly what he was saying - “there is no mismatch in the firmware in my car”. So, the car is fine. He observed that this error popped up exactly when the 2023.32.4 update was done, and he was aware that others have reported this error. He said it may or may not disappear with the next release. I’m happy - now I can relax and not worry about the battery being mis-managed.

I just did the 32.6 update and the error persists, but based on what the SC said above, I’m not worried

 

[Sai Ko]

Yes, the error is still there. Hopefully it get fixed in next update. I will switch to standard after receiving next update

 

[Sai Ko]

Just received 2023.32.7 now. Need to see if it fixes the seat calibration issue

 

[Sai Ko]

The bug is not resolved yet

 

[DigitalStorm]

I have this too, mine showed up Sept 23rd.

Just a quick update. Tesla service noted it’s likely a firmware bug and the error still persists on my car.

Unfortunately, while they were checking my rear occupancy sensor alert, they broke a latch/actuator on the seat and blamed the alert on that. When I picked up the car last week, there was a new “seat unlatched visual and audible” alert while driving, so beelined back to service immediately. They determined that the seat needs to be completely replaced, and ordered a new 2nd row right hand seat.

It’s being installed now — hoping they don’t return the car with anymore new issues. But with Burbank’s track record, I wouldn’t be surprised.
