Everythings is great---if only it didn't rattle
 There is so much I love about this car---design, styling, acceleration, interior appointments, handling, general comfort.  But unfortunately it is sort of ruined by too little attention to quality when it comes to a quiet driving experience.  I've never had a new car that has this many really severe and irritating rattles and noises.  The worst, perhaps, is a sound in the driver door or right pillar that starts over 50 mph and is wind related.  I think I isolated it to the rocker panel which must catch wind and then rattles like marbles in a rock polishing machine.  The dealership didn't do a wall job on it, but also didn't solve the problem.  The other two really annoying rattles happen when it gets below freezing.  There is an annoying clack somewhere in the back every time you hit a bump.  It's loud.  I thought it was related to the spare, but it's not.  The third rattle also occurs at road bumps or expansion joints.  It comes from the instrument cluster, and sounds like a pack of Tic Tacs over every little bump in the road.  For me, that is enough to ruin the driving experience.  Despite liking nearly everything else about the car, I probably wouldn't buy another, and this is my fourth Maxima.
