When the eco Start/stop engages and the engine restarts, the restart is hard and causes the car to noticeably shudder. Dealer told me I could turn off the start/stop, but then I would lose fuel economy. I think they fixed it for the 2018 model year, but make sure you test it before buying.

The only real gripe I have with the car is the cup holders. They are pitifully inadequate. At times it is so difficult to use that you can't get your drink in without actually pounding it in the holder. This is completely unacceptable for an automobile of this, or ANY, caliber. As for everything else, it is what it says it is and does what it was made to do very well! I can not give it a rating for the snow as I have not yet driven in the snow.
