After about 5 months our second i3, will be on a third 12v battery....
First time it was swapped during the CPO process, then swapped out again after 1 week of ownership (battery warnings)...now the i3 is back in the shop again for a bunch of faults (in addition to saying battery has insufficient charge, brought up a bunch of other warnings like steering and braking...the center console flickered out a few times while on the SOS call) that seem to be related to a 12v battery failing....won't know for sure until the diagnostics are complete...but if I had to guess, who can be this unlucky with 12v batteries...perhaps the 12v charging/dc-dc system is killing them prematurely?
Does anyone have resources they can point me toward the go over the dc-dc/12v charging system?
