Traded an 08 CX-9 for the JX.
The Mazda handled much better but the JX feels more refined.
I also have a G35 and the JX is far from handling expectations for Infiniti which is becoming more disappointing after living with the car.
It is quiet, I do like the CVT especially after 3500RPM, milage is good, lots of great tech, and great entry to 3rd row without massive rear doors.
Build quality has not been great. In 2 months, had multiple rattles, had loose trim, and now the HVAC fan is making noise.
Overall I give it a B.
Not sure i would do it again now that the honeymoon period is wearing off.
Bottom line-- test drive it multiple times before signing the papers.
Java interior, great technology, front seats are comfy (but wish there was more tilt to seat bottom).
I personally like the exterior design.
Looks much better in person that in pictures.
Interior quality is good.
CVT gets a bad rap... it feels alive but RPMs need to get above 3500 then it feels like a wound top.
2nd and 3rd row seats are too low so there isn't much leg and thigh support.. feels like you are sitting on a bench made of soft cushy leather.
Way too many rattles and poor execution issues for a $50K+ car.
luggage rack is useless.
Steering could be tighter.
Disappointed that the Nissan Pathfinder is almost identical for several grand less (what are you thinking, Nissan? Ford and GM tried this strategy with their premium brands and it did not work for them).
