I just bought my XT4 Sport FWD on the 24th. I drove it to NJ from South Carolina, After 3 days, My Father went into the hospital in Margate, Fl. Now I am back in South Carolina. I have 3400 miles on my XT4 with no problems. The highway mileage was 32 mpg, much better than I expected. The only negative was that in Florida with local traffic and a light every mile or two, my mileage dropped to 18 mpg. I believe it was because of the 4cylinder turbo which I believe is not that efficient at a lot of stopping and going.
I love the car, especially CarPlay, but the Nav system works very well with the Heads Up Display. I also learn all the functions of the knobs and buttons on my multiple trips.
