I don't know, whether the best branch to post, but decided to share my little so far but experience of driving my recently bought X1 `2016 at 105K miles. This gearbox isn't ideal. She's not perfect when's shifting down to the 2nd gear. the most embarrassing for me. Unfortunately car doesn't understand this during cornering as well. I think it's more software/electronic problem rather than mechanical. But it's just my driver's feeling. My bet is for, for that... that this Aisin gearbox is quite robust. I also get use to it and discovered some features. Not sure from car's model to model, but I have Eco mode option, which powers on only front wheels. In this mode, shifting up and down is way smoother. Good if drive alone. Also when someone sits in the car, an adult or two, e.g. adding more mass to the car - getting better with shifting as well! Such a trick, so put some rocks in the boot. Joke, but seriously, I'm about to feel, that the big part of complaints may be around a specific of this gearbox, not ideal to be fair, but probably quite robust... My point - can be drivable. Service's on soon. Will see how'll go though...
