 We purchased the Q50 because we loved our G35X so much.When we purchased the Q50 in early October 2013, we knew there were issues with the computer system.The salesperson told us that there would be a fix in November and we would be contacted.During October and November, we experienced a range of issues with the navigation system and one touch system.We had to reboot the system almost every time we drove the car.We were not contacted for the fix in November or December and we started to experience many steering issues.My wife contacted the Pittsburgh Infiniti dealer to no avail. I guess they were waiting for someone to be killed by the steering problem before taking action.Review update - 8/12/2016: we have owned the car now for almost three years.  It has never lived up to our expectations.  Cochran Infiniti (where we bought it) has not helped with liking the car.  There have been many recalls on the steering and overall technology package on the car.  The updates to the computer are poor or simply do not work after they have been performed.  Either the dealer has poor techs or the updates suck.  Not only will I never buy another Infiniti, I will not buy anything from Cochran.  I believe that the majority of the issues we experienced were due to the new model, but neither the dealer or Infiniti have done right with resolving the issues.
