    2018 tundra 4x4.....truck has been running just fine, no issues with start up or anything and this past Friday , stopped to get a haircut and was there maybe 30 minutes and came out and battery was dead.

    dealership replaced the battery for free as its still under warranty....but the thing I noticed is that when I left the dealership Saturday to get some gas and normally when I have a full tank , it will tell me the range for how many miles I can go is anywhere from 434 to 474.......now it reads that it can go 569 miles.

    why the change from just a new battery being put in ?

    Function before sparkle.
    Computer is optimistic after a reset. It will learn to be more realistic soon.

    2"CB shackles, bushings and 1 shim, lockerdown console vault, rear folding seat back mod, snugtop shell with opening side windows, 46g fuel tank, SDHQ sliders and hidden winch, Decked Drawers, Alcan leaf springs and got rid of the interior chrome
    Disconnecting the battery rebooted the system and it defaulted to factory settings. It will relearn your stuff and return to reality after a few tanks of gas
