Yes.

Don't most trucks and cars now have their lights on a timer so they shut off if the vehicle isn't running?
My old 2006 Ford F-150 does.

I would not be concerned if it’s a new vehicle. Modern cars/trucks that have elaborate electronics and monitoring draw current to maintain all of the memories when the vehicle is off. If the vehicle is not run to charge the battery for a long while it can draw down the reserve.

I have 4 vehicles for 2 drivers. I used to have a 5 series BMW sedan that if I parked it for more than a month it would give me a battery depleted warning until it had been driven enough to recharge the battery. Even when the battery had very little age on it. The car just had so much technology on it. Car dealerships have to jump off cars frequently when they sit for months at a time.

New? Like 80 grand new? Plenty of good used trucks all over for 8 grand or so, use the savings for more pins!

You are in NH. Batteries can freeze if they are dead. If this is a new vehicle the computer could detect a battery problem, and light the service light. An issue with the battery will show up right away. New car dealers do use remote lots, as there is usually no way to hold the units that the manufacture insists they carry, at the dealer site..

The vehicle may have some electrical fault that runs down the battery, leaving them to assume someone must have left the lights on, so beware.

It's pretty hard to kill a battery with a new vehicle these days. Most of them are smart enough to turn things off. Hard to say if they're telling the truth or not.
