 I've had several mechanical issues that just seem to linger - like a bad cold...  I've replaced both sensors - they keep going out.  Its December and it's 30 degrees outside and the heater doesn't work - at all.  They say it has to do with a wire that has broken from ANOTHER sensor.  Also, the car will just shut off - usually when I'm going slower.  But the car will usually start right up - that's always fun when you're coming to a stop light and the car just quits and you have to put your foot through the floorboard to stop the car.  To Nissan's defense, they have recalled for that very issue - we'll see if it gets fixed or not.  I doubt they'll reimburse me for the other repairs
