 I previously owned an FX/35 (now the QX70) and absolutely fell in love with that vehicle.  It was perfect for me...until I began expanding my family and needed more room.  Because I had such a fabulous experience with Infiniti I went back and selected a QX60 because it is a little bigger.  The good news - the fit & finish is great and gas mileage is better than expected.  I drive 70+ miles daily in rush hour traffic & I still average nearly 22 mpg.  The bad news - there is nothing else redeeming about this vehicle or Infiniti Corp.  The battery dies every 18 months like clockwork.  And, as others have stated, within months of purchasing this vehicle (with all of 12 miles on it), I began having horrible transmission problems.  I took it into the service group 7 or 8 times to no avail because it was intermittent and the techs could never duplicate it.  I was to the point of hiring an attorney when Infiniti SUDDENLY developed a 'code' that could detect the KNOWN problem I was having.  Finally, when I took it in, they read the code and BAM - new transmission.  The problem is that I have had bizarre and random hiccups with the transmission since...including a horrible clunking sound when shifting from reverse to drive.  Again, only intermittently so it cannot be easily reproduced.  I was told that, because I had the "newest version" of the transmission they would not replace it again.  Infiniti must have received an incredible number of complaints because 4 weeks after I had tried - yet again - for them to recognize the horrid clunking sound, Infiniti released a bulletin that said hearing a horrible clunking sound when shifting from reverse to drive (especially first thing in the morning) is considered NORMAL for this vehicle and had to do with either the motor or the transmission mounts.  That was it for me.  I have sworn off Infiniti and I warn everyone I know to not purchase one.  Unfortunately, in my state I missed my opportunity to sue under lemon laws, but I know I will never make that mistake again.  If I ever encounter similar issues with another vehicle I will immediately hire an attorney and get all of my money back (and my legal fees!).  My favorite part was when they told me they were extending the warranty on my transmission for another 30,000 miles...wait - you mean the transmission you swear is perfectly normal and refuse to address in any way?  Right....that'll do the trick.  Needless to say, I am now in search of a different vehicle and consider the experience a horribly costly life lesson.  DO NOT BUY THIS VEHICLE IF YOU SEE ONE AT A USED CAR LOT....seriously, don't.
