brand new Tahoe premier and was starting it this morning in -20. Truck started up no issue but after running for 10 min I get an OnStar alert that my battery is critically low. Then a message on the dash that the truck is running in battery saving mode. I got 5000 miles on this 2017. Don't have a clue what battery save mode is. And why I would have a bad battery already. Any one comment on this or what may be going on?
New Tahoe another issue. ...

Sitting on the dealer parking lot and not being started for extended periods of time. Others have experienced the same issue. New battery and issue resolved.

Battery saver mode is used for long term storage, like cross-country shipping.
Yukon Battery Saver Mode
Battery Saver Mode (Transport Mode)
Battery saver mode (transport mode) reduces the parasitic load of some modules during overseas shipment or during vehicle storage conditions. This improves the drain time on the battery (up to 70 days without the battery going dead). When a vehicle is in transport/storage, some features may have reduced functionality while in the battery saver mode, such as disabling keyless entry, afterblow, and content theft features. Battery saver mode is initiated by turning on the hazard flashers, applying the brake pedal, and then turning the ignition key to the start position or pushing the ignition mode switch with the foot on the brake for greater than 15 seconds. The mode is disengaged by repeating the previous process. The driver information center (if equipped) will display Transport Mode is On when battery saver mode is enabled and Transport Mode is Off when battery saver mode is disabled. For vehicles not equipped with a driver information center, the battery indicator light will constantly flash on the Instrument Cluster when battery saver mode is enabled. This feature can be used as many times as necessary if the vehicle is to be stored for an extended period of time.

It happens. Dealership should swap in a new battery under warranty without any issues. Sure it's a PITA and frustration but something that can easily be fixed and you should be good to go after the replacement.
