Anyone else getting poor gas mileage after software update? And just worst performance all around (not accelerating as well)

I recently replaced the engine filter and cabin filter (only one I know how to do myself....I'm not mechanically inclined)

Its going to the dealer tomorrow for a 30,000 mile maintenance...anything I just have them specifically look it?

Yep I am getting lower mileage since the software updates. I used to easily get 29-31 MPG on highway and sometimes even better, but now I barely break 27 MPG on the highway. Another change I have noticed is that that ECO button that used to be on by default is now turned off by default.

Update: It was in for service this weekend and after doing a reset and upgrade of the software in it, they test drove it and were getting 26mpg around the city. Dont have it back yet to confirm this change and will let you know when I do.

They are also changing both fuel filters on it (who knew there were 2!?) because its at 29,000 miles, I've never had it done before and I'm about to go on a 2000+ mile road trip and dont want to get the notification mid road trip.

Any other regular maintenance or pre-road trip maintenance I should be thinking about?

If you haven't checked your DEF level recently, you'll want to do that and fill it if needed. 2000 miles may use about 1/5 of a tank of DEF, so if you are around 25% or so, I'd fill it. You don't want that to run out and stop you on the side of the road.

I apparently haven't had this software update yet since my "eco" button still defaults to being turned on. Which update is this?
