My infiniti q50 will, at random, heavily pull and shift across multiple lanes of traffic. the pulling is worse during acceleration and has had at least three alignments in 2018 in attempt to correct the issue. infiniti has been unable to fully resolve the pulling and the technician, in his own words, described the vehicle as dramatic and unsafe. additionally, infiniti has replaced my driver mirror twice in efforts to reduce vibration at highway speeds. while driving at highway speeds, the mirror will vibrate making visibility and use of the driver mirror limited to not usable at all.
