$60K+ Fun to drive, but has some interior rattles
 At times I think this is the Ultimate Rattler.  Less than two weeks into ownership and there are LOUD rattles emanating from the plastic entertainment console. Simply pressing on the frame halts the annoyance for a brief time or until the next bump.  Other rattles are starting and can't determine their source.  My 10 year old Infinitis have zero rattles.  This car is difficult to get in and out from and the command center is not very intuitive. I'm 6'2" and sports seats have good support but the seat section could be wider. More than enough leg room, which is great. The car has terrific storage capacity, comparable or better than many SUV's. Never have to worry about the car bottoming out on rough road or a steep driveway, as it rides fairly high. AWD gives immediate handling confidence. Update 03/18/17: Still enjoying the car, less the "premium" rattles. Dealer did not resolve the problem...they applied a smelly oily substance between the plastic parts and no improvement. Interior rattles when temps are between 60-80 degrees. I recently noticed, in very bright light, that the #5 radio button has a horizontal hairline crack. I suspect that my radio was roughly handled before it was installed.Update 10/17/17: Had car serviced and they replaced cracked radio buttons and reinstalled radio. Alas, the problem was finally resolved and there are no annoying rattles. Of course, this did not affect performance, but I can add that I am enjoying my car much better since the rattling stopped.Update 04/18/18: Love my car more than ever. No problems at all with it.
