No? I wouldn't toss the possibility.
Point of thought: A car keeps throwing a code related to the charging system, that ultimately ends up disabling certain features on the car. Thorough diagnostics indicates the entire power and charging system is working A-1, 100%. Can't find anything wrong....
After significant time monitoring various circuits, it is noticed that there is some "extra" power on a circuit that wasn't originally designed to be there. Come to find, some engineering team made a design change, there was a mix-up/fault in communication with engineering teams, and this was not accounted for with the circuit design/power distribution and malfunction code logic. Ooops.
Of course, none of this was present in the prototype vehicles as the change was made late.
(This is based on a true story)
Anyway, my 2016 SS I could leave for at least 2 weeks before it was hard to start (I think I left it once for 3 weeks). My 2017 SS 1LE, I can't leave undriven/not on a battery tender for more than maybe 10 days or it won't even start. Not my biggest concern right now, but I am looking into this.
