Replacement battery $2500!
#347
Bottom line what they have done to save weight and money the AGM battery is too small 60 A should be 90. Combine that with having the charging system run as little as possible to maximize Fuel economy. The icing on the cake is a high parasitic draw when the car sits. As I said in my earlier post my Gt3 always runs 13 3 to 13 five so it seems that they run the charging system constantly . I would assume they’re having more trouble with the AGM batteries than the Li-on?.

I strongly suspect this is not an OTA from what he said.

Yes, please keep us posted. That in 2022 a leading manufacturer like P can't install software updates OTA is beyond pathetic, especially considering the importance such an update is to those suffering from this issue. Nuff said.

(1) They replaced my lithium battery and did the software update I referenced above.
(2) The dealer also did some work on the ground post.
For those impacted, I hope this is useful.

Thanks for posting this. Don't know what the Connect Control Unit is, is this referencing the BMS? I'm looking at my VAL to see if I can find a version number for the CCU.
Unable to find any mention of CCU or related in my VAL; 2021 992C4S LiFePO4.
PLEASE NOTE:
Grounding post work referred to is UNDER the engine and not the battery. The strap and specifically the "nut" could be corroded and thus the work done.

My notes from the latest service; very similar to @aquatone , same basic issue and same mention of the Connect Control unit although no mention of bulletin #2229 and states software level now 0412 rather than 0420 as mentioned on @aquatone's post. I got it back last Thursday and touch wood so far so good.
Interestingly over in Polestar 2 land (a.k.a. the electric Volvo sedan made in China) there are persistent issues with what they call their 'TCAM' module. TCAM stands for "Telematics and Connectivity Antenna Module" and while most of the issues are resolved by resetting that module, i.e. power reset, on occasions owners also report the 12v battery also dies. Sounds erringly familiar when you read the thread like this one.

Not sure if that was mentioned before. Apparently, the parking brake, when engaged, is a constant drain on batteries. I learned it the hard lesson...when the battery died it releases the parking brake and displays a message on dash that the car my roll away. Wonder if you guys with Lithium batteries and parking your car for extended time engage the break or not.

PS: Solenoids dont need a lot of power to stay engaged but its not zero either....long term parking may do the trick to help draining the battery. Maybe this was discussed before? Thread is too long to search for it.

I do engage the parking break though!
