My 12V start battery was depleted twice. There are different reports of depleted 12V batteries. Unfortunately this depletion made the 12V battery fail, there were bad cells. So Kia replaced it with a new 12V battery. Unfortunately the 12 V battery guarantee is only 2 years
I stated that more people have problems with the 12V battery, so there is sometimes a leakage, despite the Kia Soul EV is turned off correctly. Reports are that this could be due to the GPS module or when the charger stops in error. And because if this deep discharge of the 12V lead battery happens often, this will fail sooner or later.
The Kia dealer said there was an update, so when charging, also the 12V battery was charged. So they updated the BMS, the navigation software and cleared the ECU. I still have the feeling the real problem will not be gone and there is still a chance the 12V battery gets depleted. I am not sure if I should install a battery guard, so the 12V battery is not fully depleted. Anyone experience with installing this?
Nevertheless, all the values were reset when I checked with Torque Pro. So Min Det, Max Det, CEC, CED, all those values were reset to 0.
After the first charge from 50% to 100% the Avg Det was 14%. After a charge from 14% to 100% the Avg Det. did get back to 12.2% with 56158 km driven. Note that the new software does not contain Android Auto for my 2014 model. Also I can still charge till 80%.
