I brought my 17 in for the cam phaser tsb last fall. When I went back they told me they also did a tsb reprogram of the transmission. That was the last time I drove it until this spring. During the 10,000 miles before the recall I averaged 16.7 mpg all around, at least according to the speedo. I just did a fill up and reset the trip info . It now says 14.3 mpg avg and when I filled up it used to say 541 miles til empty. Noe it said 496. Anybody else experiencing this? I’m not liking losing 2 mpg.
