2006 Nissan Maxima Sedan 3.5 SE 4dr Sedan (3.5L 6cyl 5A)
NIGHTMARE!
 A week after buying this car in July '12, I took it back, since it had beendriving badly.After about 15 minutes of driving, the engine would rev to over 4k RPM's and then jerk hard,even slamming me back into my seat.When it did it for my husband, he insisted there was definitely a problem with the tranny.Not slipping, but rather shifting hard. My dealer waited for Nissan to respond, and of course, Nissan refused to participate.So when my dealer offered to put in a re-built tranny, it also turned out to be bad.Now waiting on Nissan rep to come investigate.Disgusted that Nissan makes a car and only stands behind it for a few years.I now wish they would stand in front of it!
