Since I have not changed my driving profile in the past three years, apparently it was not an issue for three years. Sure, an unfavorable driving profile over three years could have a "slow death" effect on a battery; however, many of these miles were done on long trips from Chicago to the West and Southwest with lots of high-speed-few-stops travel.
Last November when I reported the frequent excessive discharge messages, the tech said nothing about an unfavorable driving profile, he just blew it off with a "no codes stored" notation. In fact, the dealer has never said anything about an unfavorable driving profile, this last time only that I am locking/unlocking and opening the hood too much, which is ridiculous, as I know I am not doing this excessively.
This could be an artifact of my recent usage of a battery charger in response to the no-start incidents. When I charge the battery after no-starts, I do leave the hood at the safety latch position, rather than completely closes/latched shut. I suppose the computer might be periodically checking to see if the hood is closed to arm the alarm, and this could reawaken some modules. This might give a false reading of multiple hood openings during the charging period. However, this is not the problem as (1) this only was done AFTER the problems and no-starts began, and (2) the battery charger is attached during this period, so even if the modules awaken or fail to go to sleep, they would not be discharging the battery, And whenever the charger is attached, it does manage to reach a "fully-charged" indication.
In any case, the SA is a stand-up guy and, as noted earlier, he is insisting that a new battery be put in under warranty. I just hope that it's not just addressing the symptom and not the cause.
At the end of the day, if problems keep happening, I may have to just give-up on the dealer and do my own parasitic drain test wit a multimeter at home.
