Hi All,
Just collected my 4S from the dealer following an investigation of a single episode of 12V battery death earlier this month. My OPC has told me that they have applied a firmware update as part of a recall campaign which has fixed the problem I had. As far as I am concerned, my issue is the same as all the others reported here: 12V battery voltage dropping below 10V despite car being on charge overnight.
The recall campaign designation installed according to my excellent service advisor was WLG6. You can read more about WLG6 here: https://static.nhtsa.gov/odi/tsbs/2020/MC-10179210-0001.pdf
So the $64k question is whether anyone here has had the WLG6 update but has still suffered 12V Battery death? Others have mentioned WLG6 in this forum but I can't find any reference to someone confirming that they have still had the issue after WLG6 has been installed.
I'd love to think this bug has been squashed but WLG6 was released in August '20 and needs to be applied to the first 1486 cars off the production line. If your car was built after 11th August it should have left the line with this firmware already installed. You might imagine that most of those 1486 cars would have been updated by now in which case the number of cases should have dropped to zero if this is the fix. But has it?
So please post here if you know you have had WLG6 and have still had a 12V failure...
Thanks for your help and for all the great advice posted here on this issue, particularly from @louv and @daveo4EV...
