For example, they could have implemented some form of active cooling for the DSG gearbox to improve reliability but they didn't. A simple design say heatsink and fan that cost say usd150 to implement might have reduced the failure rate by half.
DSG rarely have issues related to heat, this issue hits the Ford Powershift DCTs. The DSG was designed in mind to have the efficiency of a manual with the advantage of quicker gear shifts compared to the normal torque converter automatics. In my opinion, what plagued the DSG was because of the focus on high speed efficiency and acceleration, which in the german home market, their autobahns' slow lane is at least 140km/h.Their market don't really need to deal much with traffic jams, so they left that out in the equation of the initial DQ200 unit (i presume) and designed it to be maintenance free without the need to change transmission fluids. Generally fine in home market, but when introduced to outside market starting in China, all hell breaks loose after just a handful of years of ownership. The frequent 1 2 3 gear shifts in a heavy traffic situation wares out the mechatronic module and coupled with the fact that consumers don't really understand that the dry clutch DSG actually houses a pair of clutch which wears of like what a manual gearbox does, a lot of complains were raised from the cost of maintenance.
Hopefully, the DSG's starting from the new Jetta and upcoming passat can last longer as they incorporated improvements to reliability and also shifting behaviour to be less harsh on slow crawl situations. I can't confirm it, but it could be the newly improved 7 speed wet clutch unit.

The only Japanese that drives like a European car is Mazda. Mazda drives more European like but the NVH is below Japanese. I think if Mazda had a turbo option, improve their NVH, we might have a Japanese that exceed European in all aspects.
All your stated points shall be fulfilled in the upcoming CX9. There are already a number of video reviews for this model. This post has been edited by wkc5657: Nov 4 2016, 11:06 AM
