While in the fast lane today, my '16 XT started decelerating like I took my foot off of the gas. No response when I pressed down. Had to coast over 4 lanes to the shoulder. No lights came on. Turned it off and waited, started it up and drove straight to the dealer with no issues. They checked it out and said it wasn't giving them any codes. They gave me a loaner and are hanging on to it for a few days to try to duplicate the issue. This has happened once before, but in town. I'm freaking out because this thing is out of warranty except the powertrain and CVT.
