What print out did you happen to give them? I called my dealership to ask if they would calibrate the MPG and after the service woman I spoke with consulted "the lead tech guy" she told me that they didn't have the ability to perform such calibrations... -_-

jakemccoy I start looking for fuel at half tank. It is not extreme because I don’t drive much (about 8,000 miles per year). Also, it lowers stress. I “start” looking for gas, meaning if I find a station I want, I will get gas. If not, I will just keep driving and singing along to the music. To me, waiting until 1/8 is extreme and stressful. You have the stress of being forced to get gas, and you have the disappointment of sometimes settling for a station you don’t want.

That sounds pretty extreme.

I too tend to fill up around 1/4 tank - sometimes a little earlier, sometimes a little later, depending on circumstances. The only time I've gotten to 17 gallons the gauge was well below an 1/8th of a tank.

I just had the update done at the end of April, because it was in for service anyway, not because of any concern. I don't really have any use for DTE given my fill up practices. But despite my gauge showing well beyond F just after fueling up (as all my cars have always shown), I've never seen a car take 92% of its capacity (17 gallons in a 18/5 gallon tank) when showing 1/4 tank left. That would generate a bit of concern - and I'm not sure that the recall even addresses this instance.

I'd say it's worth understanding why it happened / may happen again.

Instead, just spit out the level of fuel in digital and graphical format.

(I still have never used the DTE even after getting it corrected, because I do not believe it is possible to calculate an accurate DTE every time.)
I'd go for that.

Lightingguy Had the update done on my ‘17. I’ve done multiple fill-ups since, the fuel used calculation went from being off by 2 mpg over to 1.5 mpg.

crazyfingers1 Confused. The manual linked above does not say anything about the 2017 Outback but I got a recall notice for my 2017 Premium. I wonder if it's the same process. I still have several thousand miles before my 18k service.

I have no idea how accurate my low gas warning is or gas gauge is, if this has anything to do with that. I always fill at 1/4 tank anyway.

I assumed fixing the DTE was right there after they opened things up.
sorry to hear but sadly not surprised
