 I've owned the car for 6 months and the it has been in the shop for 4 months (and needs to go back). Filed a lemon law case with Nissan. Don't get me wrong I love the car - beautiful inside and out. But from day one the glass panoramic roof would pop and crack over bumps and turns... eventually the whole roof was replaced because they couldn't solve the problem. Now entire car rattles, pops and cracks. my roof isn't mounted correctly and is protruding in the back where the rear window meets it. When on the freeway the the car is extremely loud (like the window or sunroom are open) I believe it is due to the roof issues - because I don't recall this issue before the replacement of the roof. The rattling and popping is driving me insane - can't wait to get this replaced or my money back. this is my 4th Nissan in 20 years... huge fan of the brand - never had any issues with Armada, Altima and older Maxima. I have a feeling that I am in for a fight with the lemon law buy back!
