    Just got my car back from Lexus. Routine maintenance & Airbag recall.
    Prior to this moment the cruising range has always been about 270ish. Today after filling up it’s at 421. Has this ever happened to anyone?

    Welcome @Mctribe ... could the dealer have added fuel? Sometimes do on recalls.

    Thanks Ral!
    It’s possible, but I arrived at the gas station at zero on the cruising range (not too uncommon for me ‍♀️).
    I put in the same amount I usually do when at zero - about 20 gallons. And the cruising range showed 421 miles. It’s never shown anything above 270ish.

    If the dealer did some kind of software update it's possible it knocked out the real-world MPG data the car normally accumulates and uses to calculate the range. In general the first few tanks show an unrealistically large number and it gradually comes down and settles at whatever best matches how you actually drive.
