You should research the lemon laws in your state. If they can't get it working properly after so many tries, you might qualify for another JX. Hopefully, it's just a one time deal with that particular car. Mine hasn't had any issues at all for almost 5000 miles now. There's another thread about rattles in the dash, and thankfully, that seems to be limited to certain vehicles as well. I was sort of expecting the build quality to a little below all the previous Infiniti vehicles that were from Japan. That's part of my reasoning to go with a lease that's fully covered by the initial warranty.so my jx has been at the dealer for a week and they ordered some new parts but now they claim they can't get anything to work in the car. this is driving me crazy because its under 300 miles.
