Can a dying 12v battery cause a VCfront A552 and others?

[ericscottf]

Hi all,

My Nov 2018 model 3 is on its original 12v battery. Not a bad run!
I just got the 12v dying warning (VCFRONT A182 - schedule service to replace lv battery), but it comes along with a few others (parking brake degraded), including a nasty looking VCFRONT A552 - Condition detected with a vehicle controller.
I'm hoping that the vehicle controller issue is *due to* the battery being low, and I can swap the batt and be good (going to swing by the SC tomorrow to get a new battery and DIY install since a mobile visit isn't available till Friday).
I'm wondering if anyone has any insight into this, is it reasonable to assume these errors came about this way, or is it more likely that an issue with the VC front module is killing the LV batt, and I've got a more serious problem?

Thanks

Hope yours' is different. I just had my vcfront module replaced on my 18 Model 3 because it turned out to be bad. My 12 volt was only a couple of months old. Good luck.

Thanks for the reply. Do you know which error(s) you were getting? and what did it cost you to get it replaced? was the car dead or were you able to drive it while you waited?

I believe it was the VCfront 552- condition detected with the controller. It cost around $800 to fix. I was still able to drive the car to the SC. Hope that helps.

Did the fix take a long time?

FYI I had the battery replaced and all issues resolved. No problem with VCfront apparently.

Thank you for updating, had the same thing happen to me today. No service appointments for a week and a half, so headed to the SC to pickup a battery tomorrow.

As was the case with the OP, the VCFRONT A552 - Condition detected vehicle controller went away with the battery replacement.
