I watched a YouTube video that said that once the car is fully charged, the low-voltage battery will no longer be charged. So, when one leaves the car on the charger, but still not driven, (as in the COVID shutdown) the low-voltage battery would (in his words) "go flat" (run down).
I find this hard to believe.
He also mentioned a way to get into the frunk by accessing a pair of cables tucked under the wheel well molding on both sides of the car. I see that there is an emergency release latch that can be accessed from inside the frunk but no mention of these external cables. The Owner's Manual does not mention any other way to get the frunk open--other than using the key fob, app, or from the inside console. The point is, if the low-voltage battery is dead, how do you get the frunk open to recharge it? At one time I saw a hack to use a 9VDC battery to trigger the latch. I don't see a reference to that either.
