 Updated 9/2017: After much heartache and difficulty in working with the dealer and manufacturer, it appears that Hyundai has finally resolved the transmission issues found in early model Tucsons.  We have not had a problem in the months since the most recent major software upgrade.  While I'll admit that my confidence in the vehicle has been weakened by our previous experience, I am cautiously believing that we will now be able to keep this vehicle for the duration.  It is also my understanding that those units manufactured after the initial production run did not experience transmission problems to the degree that many of the first available units did.  As stated in my original review, we love the new features and really enjoy the size of this model.  If no further problems arise, we will be very content with keeping it as our main family vehicle.We want to love this redesigned Tucson.  We actually traded a 2014 model to get the upgrades included in 2016.  However, after owning the car a year, we can firmly state that we would not purchase it again.  After less than two months of normal driving, we began to experience the huge delay and hesitation in shifting from a stop.  More than a few times, I felt that my safety was in serious danger.  We took the vehicle back to the dealership multiple times to address the issue, but they did not appear to take our complaints seriously until we escalated the problem to the corporate level.  At less than six months, our vehicle got an entirely new transmission replacement.  It had literally been in the service department a quarter of the time that we owned it.  We were very hesitant to accept the "resolution" of a new transmission, however we decided to give it a try.  Another six months later, we have begun to experience the same issues again, particularly if the A/C has been turned on right after starting the vehicle.  While the Aug. 2016 software update has yet to be installed, we are extremely disappointed in this vehicle.  Our feeling is that there will continue to be "updates" for the life of the vehicle.  We do not recommend it to anyone, because the time and energy spent trying to fix these MAJOR safety issues is not worth it.  We firmly believe that someone will end up getting critically injured in one of these vehicles, resulting in a class action lawsuit.
