im a mod over at the infinitiforum site. i figured you were talking about that thread as thats really the only major active forum of this new model q across the internet.
still, thats not a lot of people, and any man made machine will have issues.
all cars have TSBs even bmw's..
the new q is born and made in japan as opposed to a line in alabama (as the armada and titan is and the old q) so the build quality is going to be better.
the new q is solid. as stated ive a 2012 all trim options AWD and have had no issues at 35K miles thus far.
