2016 Model S 90D. It doesn't happen every time, but recently, getting into the car and putting my foot on the brake preparatory to hitting the road I'm treating to a message that the system is starting up -- and it lasts a long time. It's not the first time I've seen this message, but it's taking much longer than previously. With all the updates (some of which make me grind my Tesla-teeth) of late, I'm wondering if someone else A) has this problem or B) knows what to do about it, if anything. Thanks.
